Schumacher PS-400-3A Instant Power Jump Starter

The versatile Schumacher PS-400-3A has a maintenance free, 18 ampere hour battery that delivers 850 peak amps and 250 crank assist amps. It provides extra power that 12 amp units just can't provide, making it perfect for truck and heavy duty applications. With the PS-400-3A you can make sure you're never stranded with a dead battery again. Forget about flagging down a stranger for help or fumbling with unruly jumper cables, the PS-400-3A is a rugged jumpstarter that will charge your battery and get you back on the road. And if you can't stay away from your work while you're out of the office, you can even count on the Schumacher to provide standard 12-volt power -- plug in your laptop or other devices just like you would at home. Safety and Convenience Features The PS-400-3A is loaded with safety and convenience features, including a reverse hookup protection to safeguard the car battery, computer, and Instant Power from damage in case the cables are connected to the wrong terminals.
