Editor's Pick: When your car won't start after sitting for a while, or the tire pressure warning light comes on, having one of these in your trunk can save you a lot of hassle. Just clamp it to the battery to jump-start, and it can handle gasoline and diesel engines up to 10L. When inflating, it stops automatically once it reaches your set tire pressure, so you don't have to squat there watching the gauge. If you break down at night, it doubles as an emergency light, and the port can charge your phone enough to last until help arrives.
