Editor's Pick: When your car has been sitting too long and won't start, or your tire pressure is low, having one of these in your trunk can save you a lot of hassle. With 3000A peak current, it can handle both gas and diesel vehicles, and the BOOST mode can get you going even when the battery is severely drained. It has a built-in air compressor—just set your target pressure up to 150 PSI and it stops automatically, so you don't have to watch the gauge. Five inflation modes with different nozzles cover cars, bikes, and sports balls; inflating a Model 3 tire takes just over a minute. It also works as a power bank to charge your phone, and the built-in LED light comes in handy in emergencies at night.
