Editor's Pick: When you head out on a winter morning and find your battery is dead, or your tire pressure warning light comes on, having this little box in your trunk can handle it. It combines a jump starter and an air compressor into one unit, so you no longer have to wait in line at the gas station to inflate your tires. The peak current can start 8.5L gasoline and 6.5L diesel engines, and it has reverse-connection protection, so even first-time users can follow the instructions and avoid mistakes. The 150PSI digital display air compressor automatically stops once you set your target tire pressure, and a full charge can provide around forty consecutive jump starts. It also works as a power bank to charge your phone, and the LED light has both steady-on and strobe modes so you can see what you're doing when changing a tire at night. At about 2.2 pounds (1 kg), it doesn't take up much space in your glove compartment.
