Best Tested Portable Power Stations in 2024

Which is the best portable power station?

Some portable power station features, like wireless charging, set one device above the rest. The standout for us was the Jackery 2000 Plus. Jackery’s offerings are usually solid in the portable power station arena. Helping set this model apart: the ability to expand the 2000 Plus by adding external batteries, increasing its overall capacity and capabilities. And with Fourth of July sales underway, many of these picks are seeing significant savings.

As electronic devices become ever more integrated into our daily lives, the need to keep those devices charged and online increases, but we can’t bring the power grid with us wherever we go. Portable power stations are the perfect solution to keep us electronically powered anywhere. These devices have enough bells and whistles to justify adding one of these to your everyday life, but they can also be an inexpensive stand-in for generators when you need to keep your absolute necessities up and running.

If you’re looking to juice up your devices, you’ll have way more options than bulky, simple power banks with basic outlets. Portable power stations have undergone major improvements since we first started reviewing them here at CNET, bringing about features like USB ports, solar panel inputs and wireless charging. You can daisy-chain some models for even more power, or connect others to your home’s electrical system, giving you backup power in an emergency or power outage. You’ll also find plenty that work just as well as portable generators for camping trips and other off-grid activities.

To find the best of the bunch, I spent hours putting each power station through its paces, and I also considered factors such as battery life, power output and input charging options, plus output options for juicing up my gear. Power stations that only sport AC outlets and force you to use adapters are no longer viable. Each is more than just an on-the-go phone battery charger or glamping must-have. These power bank performers have wide-ranging uses, from building and construction to staying connected with the office or family to having access to emergency lighting and power wherever you roam or call home. 

Best portable power stations for 2024

How we test portable power stations

Currently, we look at two main performance metrics for portable power stations: charge time and discharge capacity. Every company that sells portable power stations provides the expected number of watt-hours its products are supposed to last. For the Jackery Explorer 240, that’s 240 watt-hours; for the Ecoflow River Max, it’s 576 watt-hours. Bluetti AC200P claims 2,000 watt-hours. 

That means if you run a device with a 1-watt output on the Jackery Explorer 240, it should last for about 240 hours. You’d get 576 hours from the Ecoflow model and an impressive 2,000 hours using the Bluetti generator. That would last you almost three months. For reference, a USB-C iPhone charger draws up to 18 watts, a 3-quart Instant Pot draws 700 watts and a standard microwave draws around 600 to 1,200 watts, depending on the model. But how accurate are those figures?

Usable capacity

A power station’s capacity should be a no-brainer. You should be able to look at a device’s rated watt-hours and purchase accordingly based on your needs. Generally, you can do that. That said, I’ve found that you typically won’t see the entire capacity rating as usable power. 

Lots of factors can affect this, and most of them center on how the manufacturer chooses to build their units’ internals to manage their charged capacity. There is some (usually negligible) amount of power that goes to fuel the various indicator lights and readable LED panels on the units. Some of the larger units even have their own operating systems, so it’s almost like powering an additional mini PC on the inside. Other units can have power-saving features where they reduce outgoing bulk power as they come close to depleting their charge.

To run our capacity tests, we connect a number of 10,000-lumen LED work lights, rated at 110 watts, to each unit. (The number of work lights is based on the overall watt-hour rating of the unit under test, or UUT.) We record the outgoing voltage and wattage using external measurement instruments or the UUT’s own measurements if available. Once we have this data, we can leverage the calculations into a dizzying array of information about the UUT’s performance. The main piece of information we look at here is the observed capacity, based on our measurements, compared to the UUT’s stated capacity.

Here’s that mass of data in a nifty chart, where longer bars indicate power stations with greater percentages of battery capacity that you can put to use.

In every case, that percentage ends up at less than 100%. Most manufacturers say you should calculate expected usage at 85% of stated capacity. Two of our smaller units (green bars) both clocked 98% capacity — the Jackery Explorer 240 and the Togo 350. Generally speaking, the midsize units (blue bars) didn’t fare well. The large-sized units (yellow bars) did better, with the Bluetti AC200P scoring highest at almost 96%. As for our extra-large units (purple bars), the 3,600Wh EcoFlow Delta Pro fared the best, with a usable capacity rating just over 92%. Behind it, Oupes, Mango, Yoshino and Dabbsson each had extra-large power stations (at least 2,200Wh) that scored above that 85% benchmark for usable capacity.

A quick word on our math here. If you blindly accept both a unit’s stated capacity and our work light wattage rating of 110 watts, the numbers look very different. For example, we will take the GoSun PowerBank 1100 (to make the math easier) and attach four of the 110-watt lights. That load rating is now 440 watts and the GoSun’s capacity of 1,100 divided by 440 is 2.5. We would expect to see 2.5 hours of usage. The actual run time for this unit was 2 hours, 50 minutes — 113% capacity. Sounds great, Right? We’re missing some key factors. Without going into a long(er) explanation of how to more accurately measure power, the fact that this unit has an output of 110 volts AC (compared to 120VAC) and the actual output wattage to the four lights is 352 watts, our real expected run time is 3 hours, 8 minutes, which drops the capacity rating to 90%.

One other testing note for these numbers — the Oupes 600W data might be off. The unit turned off the lights at 9%. It would allow me to start the lights again but would turn them off again after some time. I repeated this process at least 20 times before the unit wouldn’t power the lights for more than a couple of seconds at a time.

Charge time

Charging performance can be nearly as important as knowing your capacity stats. It helps to know how long your device will take to charge, especially if you’re crunched for time or need to be able to charge quickly for whatever reason. Will it take 1 hour or 2? What about 10? Or 12? (That’s an actual number from our tests.)

We report three data points for charging performance. Each unit is plugged in for AC charging and we record how long it takes to reach 50%, 80% and 100% charge. Half-full is probably the least amount of power you’re going to want, especially from the smaller units. 80% is the “magic number” for many rechargeable batteries. 

Here’s a simple-ish way to illustrate it: Imagine a swimming pool with room for 100 people, each person representing 1% of the total space. When you first start charging, and that first person dives in, you don’t have much to worry about. You’re not going to run into anyone else, so dive, splash around, whatever you want. But as we add people, it gets a bit more crowded and complicated. You’ve got less room for people. Once you have 80 people in the pool, that next person is going to take a few extra seconds to choose their entry without causing any issues rather than just jumping and hoping no one is in the way.

Each manufacturer deals with this purposeful slow-down in its own way, so you won’t see the same performance changes from one manufacturer to the next. True to the analogy, person number 100 into the pool can sometimes be very slow, taking several times longer to get in than any of his predecessors.

Take a look at the full charge test results below. Charge times are listed in hours, so shorter bars indicate power stations that charge faster. In many cases, you can see how the charge rate is fairly constant between 0 and 50% (red) and from 50 to 80% (yellow), before slowing down from 80 to 100% (green).

Other portable power stations we’ve tested

Ampace Andes 600 Pro (584Wh): This is an OK unit. It sits right around the industry standard for usable capacity. However, we did find that the charging moved much slower than the marketing materials claim – 90 minutes to 80% charge vs the advertised 60 minutes.

Anker 555 PowerHouse (1,024Wh): An increasing number of portable power stations are shipping with LifePO4 batteries, and I love that. The 555 is slower to charge than most of its competitors but sports a 94% usable capacity and an attractive price versus the number of watt-hours; the better to power those six AC outlets.

Anker Solix C1000 (1,056Wh): Another good option from Anker. It tested well in our lab and I don’t have any real complaints about this one. Anker currently has it at $250 off, which is great, but it also offers 30-day price matching. You could end up with an amazing deal this time of year. 

Anker Solix C800 Plus (768Wh): So, I kind of like this guy. It only really performed average in our standard tests for power stations, but it has a feature that is quite interesting, if not a bit gimmicky. In a storage compartment on top of the unit, you will find a telescoping pole that can be mounted onto the power station to support one of two rechargeable camping lights. You’re not getting a ton of light out of these things, but, some light is infinitely better than no light. Plus you get the hands-free mode with the telescoping pole mount – maybe that is what the ‘plus’ is for?

Anker Solix F1200 (1,229Wh): This unit was previously known as the PowerHouse 757 from Anker, and was also CNET’s previous pick for “best portable power station for backup.” Its UPS mode was one of the earlier units to boast “less than 20ms” switchover time in the event of a power outage. It’s also currently $349 off on Anker’s site. 

Anker Solix F2000 (2,048Wh): Previously known as the Anker PowerHouse 767 and previous winner of “best large portable power station” here on CNET. This model has lots to offer by way of features and options — pretty much anything other than wireless charging. It also performed well on our usable capacity and charge time tests. 

Bailibatt 300W (257Wh): Another small, affordable unit. The Bailibatt comes in at 84% usable capacity, which is good. But it takes 11 hours to charge, which is…. not as good. If you have specific limited charging needs and plenty of time to recharge, the price tag makes it worth considering.

BioLite BaseCharge 600 (622Wh): Here’s a unit that’s about average with an OK price. It has 87% usable capacity, a Li-ion battery, average features and is maybe a little slow on the charge time. On the plus side, it does have wireless charging.

BioLite BaseCharge 1500 (1,521Wh): Having tested both the 600 and 1500 models of the BioLite BaseCharge, I can tell you that this company is consistent in its product manufacturing. The BaseCharge is about 2.5 times the capacity of the 600. That 2.5 modifier carries across the board fairly accurately from price to capacity, charge times, everything. If you like the 600 but you wish you had two and a half of it, save yourself the effort and just buy the 1500.

BigBlue Cellpowa 500 (537.6Wh): This is a better-than-average performing unit at better-than-average pricing. But there’s nothing outstanding about it. 

Bluetti AC180 (1,152Wh): This unit tested well enough, scoring 88% usable capacity and charging via AC outlet at 13.88 watt hours per minute, but one thing to clarify, unlike many of the other Bluetti units that use the same physical format, this unit does not support capacity expansion via external batteries. 

Bluetti AC180T (1,433Wh): I like this unit, but I’m just as, if not more, excited about its energy platform, the SwapSolar Ecosystem. Not unlike some of the Runhood units we’ve tested, this ecosystem uses interchangeable batteries that will power multiple products from the brand. We have also tested an electric cooler on the same ecosystem. As far as large power stations, the performance metrics were great with this unit, just not quite enough to capture a title.

Bluetti AC2A (204.8Wh): A great option if you don’t need a ton of capacity but do need options beyond just USB connectivity. This unit is in the capacity ballpark of a very large power bank and priced similarly while currently on sale through the manufacturer for $159.

Bluetti AC200P (2,000Wh): This is one of Bluetti’s earlier large portable power stations and a previous winner for “best large portable power station.” It’s currently over $500 off on Bluetti’s site. It still offers plenty of power and options, but is likely nearing the end of its product cycle lifespan (hence the $500 discount). 

Bluetti AC240 (1,536Wh): I’ve tested a dozen or more Bluetti power stations at this point. The AC240 is good, as are most of Bluetti’s offerings, but I wasn’t particularly blown away and didn’t find anything new to be excited about here. It performed slightly below many other Bluetti units on the usable capacity test, but does have many of the expandability options I admire, and UPS switchover times are coming down across the board – 15ms on this unit, although I’ll be happier when sub 12ms is the standard.

Bluetti EB3A (268Wh): If you’re interested in something small to work for your personal charging needs but those pocket-sized battery packs just don’t cut it, this could be your option. As a previous CNET “best value” winner, the EB3A has what you need to keep rocking for a couple of days. 

Bluetti EB55 (537Wh): We’ve liked almost every unit from Bluetti, and three of them took previous titles in this best list, but this unit was overshadowed by its siblings. Offerings that are just as good or better at better prices keep the EB55 out of the winner’s circle.

BougeRV Fort 1000 (1,120Wh): I’m a fan of BougeRV’s approach to camping and outdoor products in this space. It’s worth checking out, especially if you’re looking for more flexibility in areas like solar panels or DIY options. The Fort 1000 did well in our tests but didn’t stand out enough to capture any titles. 

Dabbsson DBS2300 (2,300Wh): I love that it’s a modular format, expandable up to 8.33kWh. The 87% usable capacity is good, and charges relatively quickly. It charges at over 18 watt-hours per minute, for a total of 122 minutes to charge the entire 2300Wh.

Dakota Lithium PS 2400 (2,060.8Wh): What I believe is Dakota Lithium’s first traditional portable power station (certainly the first I’ve tested), is a home-run. It showed a respectable 90.72% in usable capacity while also giving us our fastest charge metric to date. We showed a charge rate of 26.76 watt-hours per minute, just edging out the Oupes Mega 3 by about .3 Wh/m. Of course, Dakota Lithium is not new to the power game, and that momentum is likely why we’re seeing such a strong start for them in this space.

DaranEner NEO2000 (2,073.6Wh): This unit didn’t win any categories, but it did perform in the top tier for our charge tests and came in about average for our usable battery capacity tests. This sturdy unit has plenty of features and one of the lowest prices per watt-hour.

Deeno GT S1500 (1,036Wh): We previously tested the Deeno GT X1500 and the S1500 is a big step up. It has the same capacity and same pricing, but with nearly 20% more usable capacity than the previous model and it charges nearly 5x faster.

Deeno X1500 (1,036Wh): The X1500 did not fare well in our tests. It came through with one of the lowest usable capacity scores we’ve collected so far at 69.88%, meaning you see about 724Wh out of the stated 1036Wh. For the price, there are better options. 

DJI Power 1000 (1,024Wh): I want to note first off that I do not have a drone that is compatible with the SDC super-fast charge function for select DJI drones. And I think that is likely to be one of the best selling points for this particular unit. I’m also happy that there are two 140-watt USB C ports. But outside of those features, there isn’t much else to talk about. It does charge fast but it came in low on our usable capacity test.

Duracell Power 500 (515Wh): This is the first Duracell unit I’ve tested, but not the first battery brand (see Energizer at the top of this list) to put out a portable power station. So far, the results are similar. Test results come back with under average performance and questionable prices. 

Duracell M250 (219Wh): Overall, this smaller unit is proportionally comparable to the larger Power 500 Duracell model. The M250 came in at 75% usable capacity, just a couple of points higher than the Power 500. And you’re getting approximately half the capacity for half the price. Charging is also in line, taking around the same time (4 hours plus) to charge half the capacity (at half the input power). I like the cylindrical shape — I’m guessing Duracell wants it to look like that familiar battery profile — and that the lid opens up to allow for power cable storage within the unit.

EcoFlow River Max (576Wh): Blazing fast charging and a low cost per watt-hour make this a reasonable pick, although this unit did test lowest in measured versus expected capacity, putting it at 425 usable watt-hours. Where’d those extra 151 watt-hours go?

Ecoflow River 2 Pro: A previous title holder for “best budget portable power station,” this is still a great pick for anyone looking for affordable power options. It charges fully in just over 1 hour and accesses a respectable 82.6% of the battery’s 768Wh stated capacity.

EcoFlow Delta 2 (1,024Wh): The EcoFlow Delta 2 is similar to the Anker 555 PowerHouse across the board — features, pricing and so on. The main differences you can see from our tests are the usable capacity percentages: Anker with 94% versus EcoFlow with about 70% and charging rates. Both are rated at 1,024Wh. The EcoFlow Delta 2 charged to full in only 86 minutes, 275 minutes faster than the Anker model. Another point for EF is that it can wire in a secondary battery module, taking the capacity from 1,024Wh to 2,048Wh. Expect to pay an additional $300 for that battery expansion. 

EcoFlow Delta 2 Max (2,048Wh): Another example of a great product that didn’t capture any of our titles. The Delta 2 Max performed well in all of our tests, and with the ability to expand to 6.144kWh, you’re really walking the line between a portable power station and a whole-home energy solution. 

EcoFlow Delta Pro (3,600Wh):The EcoFlow Delta Pro is one of the largest portable power stations on our list at 3.6kWh (expandable up to 25kWh), and also happens to be one of the fastest charging. Lots of power, and plenty of charge options to keep that power rolling.

Encalife UAF550 (595Wh): Of the three Encalife chargers, this has the largest usable capacity percentage at 87% but the slowest charging at 1.98-watt hours per minute. 

Encalife UAF1100 (992Wh): Industry standard usable capacity here at about 84%, but a bigger drop in the charge capabilities at 3.35-watt hours per minute from its larger sibling.

Encalife YUE2000 (2,048Wh): A bit of variation in our model hierarchy groupings with Encalife. As you might expect, charging capabilities do increase with larger units. The YUE2000 being the largest of the three charges relatively quickly, at about 11.13 watt hours per minute. In this series, the usable capacities trend in the other direction, with this unit showing 73% usable capacity.

Enernova ETA 288 (288Wh): This is another example of a hierarchy of models where the smaller units underperform, but larger models improve. This unit took about 3 hours and 40 minutes to charge, but it reached about 81% usable capacity. 

Enernova ETA Pro (1,050Wh): Moving up a notch, this one has 83% usable capacity and charges 1kW in about 1 hour and 30 minutes. It’s a better showing and about 10 cents cheaper per watt-hour than its smaller sibling. 

Enernova ETA Ultra (2,150Wh): This is the best of the three, sporting 2160Wh, 87% usable capacity and it charges in under 2 hours. 

Energizer PPS700 (626Wh): OK performance and features overall, but one of the lowest-tested capacities, making the usable capacity closer to 477Wh.

Fanttik Evo 300 (299Wh): This is a solid pick in the small power station category, and this unit has my favorite display: It’s extra large and easy to read. We did see average performances on our charging and capacity tests.

Generac GB1000 (1,086Wh): Generac has been a household name in the power landscape (especially generators) for dozens of years in the US. It isn’t that surprising to see it here in the portable battery space. That being said, I wasn’t blown away by this unit. It tested quite average (if not a smidge below on charge speed) but overall, still does what you need it to — transport power.

Geneverse HomePower One (1,002Wh): This unit was the second slowest overall to charge, but did well on its usable capacity rating at 91%. Its display is small but offers all the standard input and output features you’d want.

Geneverse HomePower One Pro (1,210Wh): This is the grownup version of the Geneverse HomePower One. The feature specs are about the same, but at $500 more, you’re only getting about 200 extra watt-hours. In addition, the standard One model comes in at 91% usable capacity versus the Pro model’s 73%. That gives you 912.6 usable watt-hours with the standard and only 886.7Wh on the Pro. The Pro charged in almost a quarter of the time it took the standard version. 

Goal Zero Yeti 200X (187Wh):: The Goal Zero products are solidly made, but we got the lowest score in our “usable capacity” tests from this unit. It’s about 65% compared to the industry-accepted norm of 85%. There are better products in the small portable power station category. 

Goal Zero Yeti 700 (677Wh): Overall this unit tested OK — nothing outstanding. One of the more interesting aspects of the design is the use of these plastic protective ‘flaps’ covering the in/output ports. The use case here seems to be a more rugged durability for camping or otherwise roughing it where you might have an increased exposure to mud, dirt, dust or water. Outside of those environments, the flaps can be a bit bothersome.

Goal Zero Yeti Pro 4000 (3,993.6Wh): Runner up for our best extra large power station title, the Yeti Pro 4000 is a tank (which, by the way, is the name of the expansion battery “Tank Pro 4000”). You get tons of input and output options, and overall expandable to 20kW capacity. We were able to charge this via standard AC outlet in 2 hours and 49 minutes, giving us our third fastest charging rate so far at 23.63 Wh/min charged, and also offers 3,000W solar input. If you’re looking into home backup, also check out the Haven10 transfer switch accessory to bring your home online.

GoSun PowerBank 1100 (1,100Wh): I wanted to like this unit more, partially because of GoSun’s extended offerings of solar-friendly devices. As far as capacity goes, this runs in the middle of the pack, but man is it slow to charge. It took nearly 12 hours — over 6x as long as our largest power station (Jackery Explorer 2000 Pro) — which offers nearly twice the capacity. At $1,099, I’d like to see a faster charging option and maybe more outputs or at least wireless charging.

Jackery Explorer 240 (240Wh): We’ve been fans of all the Jackery units we’ve ever tested in the past, and that doesn’t change here. Just missing the best small power station title, this unit still boasts the second-best capacity rating of all the ones we tested. It was a little slow to charge but is offered at a great price.

Jackery Explorer 300 Plus (288Wh): Another nice entry into the platform, the 300 Plus offers a solid power option in small form. Not a ton of frills, but it does what you expect it to do. 

Jackery Explorer 700 Plus (680.96Wh): If you need more power output than the 300 Plus (300W/600W) then the 1,000W (2,000W surge) of the 700 Plus may be what you’re looking for. It will charge via AC in about 1 hour and 30 minutes, and it has one of Jackery’s higher usable capacity percentages at 88%. 

Jackery Explorer 1000 Plus (1,264Wh): The 1000 Plus has a stated capacity of 1,264Wh paired with a 2,000W output. The new “Plus” line also supports capacity expansion through external batteries. With this unit, you can add up to three extra batteries for a total of up to 5kWh. Charge via wall outlet in about one and a half hours; double that if you max out the 1000 Plus’ 800W solar charging input and go that route instead. 

Jackery Explorer 1000 Pro (1,002Wh): The 1000 Pro falls into our large portable power station, which begins at 1,000Wh (this Jackery weighs in at 1,002Wh; the same as its big brother, the 2000 Pro). I like the 2000 more than the 1000 for a few reasons, so the 1000 never had a shot at taking the “large” category. That said, it still has good performance, nice features and amazing charge times.

Jackery Explorer 1500 Pro (1,512Wh): With this Jackery you will get a dependable machine that performs well in our usable capacity tests at 90.4% and charges quickly: 0 to 100% in 2 hours, with AC-only charging. Toss in a couple of solar panels and you can drop that time down quite a bit. 

Jackery Explorer 2000 Pro (2,160Wh): This was a previous title-holder of the “fastest charging portable power station.” The Jackery units overall are great and dependable. If you’re looking for a model (really, an entire lineup) that will recharge fast with multiple, even combined options, Jackery is a no-brainer. 

Jackery Explorer 3000 Pro (3,024Wh): Another beast of a unit and a great offering from Jackery. If you’re already a Jackery fan but need more battery capacity, this is an easy win for you. Otherwise, recent improvements include wheels, telescoping handling and that round RV plug we’ve been waiting for.

Lion Energy Safari (1,612Wh): I tested two units, the first I’ve had my hands on, from Lion Energy. Two immediate observations on the superficial side: First, I like the physical packaging of these units. Reminds me a bit of Oupes, which I also like. And second: These things sound like the names of energy drinks.

Otherwise, I wasn’t impressed. This larger unit also had a bad connection to its display screen. In general, the color screen looks better than most other options. But in my case, I had several lines plaguing each view.

Lion Energy Summit (665Wh): The TLDR is above with the larger unit, but for additional context, but units tested about average in terms of usable capacity. My main performance complaint would be with charge speed. Both units are a bit low for their capacity category. I would be happier if the Summit charged at the Safari rate, and the Safari was retooled for near double its current speed.

Litheli PowerHUB B600 (562Wh): This one can be slow to charge, but otherwise, there’s a lot to like here. It has good usable capacity at a decent price since it’s currently marked at about 30% off. Litheli is also offering a battery platform (U-Battery) with this unit. Two smaller batteries plug into the main unit that you can then use with a variety of other tools. Check out our upcoming coverage on handheld vacuums to see Litheli’s performance there. 

Litheli PowerHUB Eclair1000 (1,069Wh): Another unit from Litheli offering the U-Battery platform, but it’s closer to double the capacity of the last unit we tested. The capacity score was low, but the charge speed has vastly improved from the B600. Worth a look if you’re interested in the U-Battery platform.

Mango Power E (3,530Wh): I mentioned this unit earlier as the runner-up in the “fastest charging” category. This thing is loaded with features, even allowing you to provide 240-volt service by linking a second unit. There are also battery expansions for the Mango Power E. The one downside is the price tag, as this unit also comes through as the most expensive portable power station with a list price of $2,799. 

Milwaukee M18 Carry-On Power Supply: This is a different unit to include on this list, but it does meet all the requirements, so here we are. Likely interesting mostly for Milwaukee tool platform fans, here is what you need to know: It isn’t a great portable power station. That being said, you’re probably considering buying it because you’re already on the platform. And if that’s the case, I say go for it. It will work with all batteries on the M18 platform, so you have some control over how much juice you want to carry around. This will put a fair amount of convenience into situations for people who are Milwaukee tool users and find themselves in energy-shy situations.

Monster Power Grid 300 (296Wh): The Power Grid 300 can be slow to charge but did test at over 90% usable capacity. It has all the bells and whistles you’d expect at this level at a price that’s potentially a tad high. 

Oscal PowerMax 700 (666Wh): Another unit that didn’t perform particularly well in our tests, but does boast a ton of features including a “non-stop continuous power supply mode.”  

Oukitel BP2000 (2,048Wh): This is the first unit we’ve tested from Oukitel (along with its expansion battery — we will be publishing more on expansion batteries soon) and we were pleasantly surprised. To begin, the BP2000 scored an impressive 90% on usable battery capacity and also scored well in our charge tests, taking less than 2 hours to charge all 2048Wh of capacity. Oukitel is also leaning into the modular and expandable approach, allowing you to add up to seven additional units for a total of just over 16kWh of power. As well, the BP2000 boasts sub 10ms switchover time as its UPS feature.

Oupes 600W (595Wh): Not a bad little unit. I love that it has the LifePO4 battery. It performed about average (maybe a hair under par) and I feel like it could be cheaper. The name can be hard to pronounce, though. “Oops” is our best guess.

Oupes Mega 3 (3,072Wh): Another great offering from Oupes with stellar performance. The numbers from our test lab slightly favored the Mega 3 over the Mega 5. We also tested the B2 expansion battery with this unit and further improved the numbers for usable capacity. The Mega line continues to impress with both performance and value.

Oupes Mega 5 (5,040Wh): Previous titleholder for “best extra-large power station,” the Mega 5 is a beast. It maxes out at 5,040Wh, with a single expansion battery option, the B5, bringing the total to 10.08kWh. At 4,000W output with a 7,000W surge, you’ll be able to power pretty much anything you want (as long as it uses either a standard 120-volt plug or the round RV type). It also has a large solar charging capacity (4,050W) and in our tests, proved to be one of the fastest charging units we’ve tested (second actually), going from 0 to 100% in 214 minutes, or 3 hours and 54 minutes. That ends up being 23.55 watt hours per minute charged, which is the second-highest rate we’ve recorded. 

Pecron E1500 (1536Wh): I will say that I’m a bit torn with this unit. I tested the E2000LFP model first and was impressed with the results. The E1500LFP did not fare as well. Specifically, the usable capacity came in especially low at 68% compared to the E2000 at 94%. Other than that, the charging is beefier, charging at about twice the rate as the other unit. And you still get perks like wireless charging and expandability from 1536Wh up to 7680Wh.

Pecron E2000LFP (1,920Wh): I discussed this unit briefly earlier as the runner-up to the Delta Mini in the “best portable power station for camping” race. It has more options than the Mini and is suitably priced. I’m also a fan of any of the companies that adopt the modular approach with the capability to expand capacity with external batteries like Pecron has done. You can also pick up a rolling caddy for the unit if you’re on the go.

Phyleko ENF1000S (1,024Wh): I’ve seen this body style before in the GoSun 1100 — it feels super sturdy and I do like the larger colorful display. Otherwise, this unit landed just under average in our tests. 

Power Cache 300 (293.76Wh): We tested a trio of power stations from Power Cache. The 300 model did well as far as usable capacity goes (91%) but did take over 7 hours to charge. Another upside — it’s affordable, with its $199 retail tag.

Power Cache 600 (642.6Wh): Costing $250 more than its smaller sibling, this middle child showed the least impressive performance of all three models coming in at only 72% usable capacity and taking over 8 hours to charge to 100%. But if price is your main concern, it’s an affordable option.

Power Cache 1000 (1,075Wh): The largest of the three units, this one performed moderately, coming in at 82% usable capacity and taking about the same amount of time to charge as the small 300 model, which is just over 7 hours. That does mean it charges over four times faster than the small unit, but 7 hours is still 7 hours. Selling at $800.

Renogy Phoenix 200 (189Wh): Slower to charge, but it has 96% usable battery capacity paired with the lowest price of any unit we’ve tested. This a great option for smaller use cases or for people generally interested in checking out portable power stations at a reasonable price. 

Renogy 1000 (998.4Wh): This is another decent performer. It charges fast enough for its relative capacity category, but only offered us about 80% usable capacity. Normally I wouldn’t be too bothered, but the smaller Renogy unit we tested clocked in at 96% usable capacity, so I was hoping for more. 

Rockpals 300W: This unit also came in under the line in usable capacity. Given the industry standard of 85%, Rockpals’ 78% is lacking. In terms of charge speed, this unit is one of the faster small portable power stations. It has decent features and kind of looks like a handheld radio. 

Rocksolar Nomad RS650 (444Wh): Until the company updates this unit, there are likely better options for almost anything you’re looking to do. It has a high price, low usable capacity, slow charge time and is low on features and options, but it does work. 

Runhood Rallye 600 (648Wh): There are a couple of these types of units on the market now, and I’ve been waiting for their arrival. This Runhood unit is the first modular-style portable power station I’ve been able to get my hands on, and I love what it means for the industry. Performance-wise, this model was about average, but it could offer you more in flexibility and convenience than many other units. The batteries are swappable, so you can pick up extras, in addition to standalone AC and USB modules that can use those extra batteries without being plugged into the main power station unit. This could be a game changer for trips where every member of the family is off in a different area draining some electronic device. I look forward to adding a “best modular power station” category soon.

Runhood Rallye 1200 (648Wh): The capacity is the same for this unit as it is for its younger sibling, the 600 (listed above). The 600 and 1200 designations refer to the constant power output in watts, with each unit’s peak power doubling that constant power number. You do get an extra AC outlet but the increase in power output is the main difference. Likely worth it if you’re into the modular design, but need more power than the 600 has to offer.

Togo Power Advance 346 (346Wh): This unit held the title for best small portable power station for about two years on this list; solid performance, great features and an attractive price tag. 

Ugreen Power Roam 600 (680Wh): This unit didn’t do great in our tests, but it has a reasonable price. It charges quickly, but that has more to do with the smaller capacity than an elevated charging capability. 

Ugreen PowerRoam 2400 (2,048Wh): I was happy to see that this model did better than the previous smaller model we tested. 83% on usable capacity and it charged in the same amount of time as the smaller unit, about an hour and a half for each one, which means the 2400 was charging at about four times the rate. This one also has wheels and a telescoping handle for ease of movement.

VTOMAN Flashspeed 1000 (828Wh): This is the second VTOMAN Flashspeed I’ve tested, and the smaller of the two. This smaller unit didn’t fare as well as its big brother in our tests. While it’s a capable machine, I would struggle to find a scenario where the minimal cost difference between the two would keep me from buying the 1500 over the 1000.

VTOMAN Flashspeed 1500 (1,548Wh): This unit did about average on our usable capacity test, but, charging from 0 to 100% in 64 minutes, the FlashSpeed 1500 sees 24.19 watts-per-minute charging from a standard 120-volt, 20-amp residential outlet, which is one of the fastest charge rates we’ve seen here in the test labs. If charge speed and time are primary concerns for you, it’s almost impossible to do better than the Flashspeed 1500.

Yoshino B330 SST (241Wh): This is a “cute” little power station. It has a USB-C 100W port, a couple of AC outlets and is pretty light for what it offers. It comes in just above average for usable capacity but does have a slow charge rate. But if you’re looking for a little power in a compact package, it’s worth considering.

Yoshino B4000SST (2,611Wh): This unit tested fairly well in our lab. 87% usable capacity, blazing fast charge speeds and a decent feature set. It’s an option worth considering if you can find it on sale. 

Zendure SuperBase Pro 2000 (2,096Wh): The first unit we tested with the Li-NMC battery composition. This unit also just missed the best large portable power station title. It has a weight-to-capacity ratio, likely thanks to the NMC composition and boasts our highest solar charging capacity to date at 2,400 watts. Its telescoping handle and wheels make it easier to manage, but the form makes it better for navigating paved walkways than “off-road” terrain. 

70mai Hiker 400 (378Wh): This unit didn’t fare too well in our tests, coming in at about 75% usable capacity (versus the industry standard of 85%) and taking about 4 hours and 30 minutes to charge its 378Wh. 

70mai Tera 1000 (1043.9Wh): The larger of the two 70mai units tested better, hitting the industry standard for usable capacity and taking about 20 minutes less to charge nearly three times the capacity of the smaller model.
