Editor's Pick: If your car has been sitting for a long time and won't start, or the battery dies in winter, just clamp it on and it starts in seconds. Peak current of 4000A can handle gas engines up to 12L and diesel engines up to 10L. The 20000mAh capacity can jump-start about thirty times, and it doubles as a power bank for fast-charging your phone. IP66 waterproof, so you don't have to worry about moisture in the trunk, and if you break down at night, the built-in flash and SOS lights come in handy. Comes with a hard shell carrying case and smart clamps, so you can pack it away right after jump-starting without taking up space.
