BLACK+DECKER J312B Power Station Jump Starter: 700 Peak/300 Instant Amps, USB Port, Battery Clamps

With the BLACK+DECKER J312B jump starter and power station, you no longer need to dread roadside emergencies when your vehicle won't start. This compact, portable device delivers jump-starting power with 600 peak amps and 300 instant starting amps. That's enough power to jump-start your car, truck, SUV, motorcycle, boat, RV, ATV, or tractor; all without the need to use another vehicle for assistance. Simply connect the clamps to the battery, turn on the switch and start your vehicle. The reverse polarity alarm will alert you when there is an improper connection. The built-in USB port comes in handy to charge your phone and electronic devices. It features an integrated charging cube (a 120V charging adapter) that allows the STANLEY J312B jump starter to be charged using a standard extension cord, so you don't need to keep track of a separate specific charging cable.
