With a peak current of 6,000 amps, this compact Avapow jump-starter is the most powerful model you’ll find on this list, and it can handle just about any vehicle on the road. That includes any gasoline engine, and diesel engines of up to 12 liters — making it great for cars, trucks and motorcycles, as well as boats, ATVs and more. Plus, the intelligent jumper clamp has eight different protection systems in place so you don’t damage the starter or your battery. Just note that you’ll have to add it to your cart to see the discount.
