Editor's Pick: When your car has been parked outside for a few days and won't start in the morning, this saves you from waiting for roadside assistance. Clamp it to the battery and it starts in seconds, and it can handle 10.0L gas and 8.0L diesel engines, working even in sub-zero winter weather. It also doubles as a 20000mAh power bank for fast-charging your phone, with three built-in LED light modes for nighttime repairs or camping. A full charge holds enough for about 50 starts—just top it up every three months.
