With the STANLEY J309 Jump Starter and Power Station, you no longer need to dread roadside emergencies when your vehicle won't start. This compact, portable device delivers 600 peak amps and 300A of current to a 12V battery for a quick and easy startup of your vehicle. 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. A high-powered LED light rotates 270 degrees to help you work in the dark. The built-in triple 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 J309 Jump Starter to be charged using a standard extension cord, so you don't need to keep track of a separate specific charging cable. Extension cord sold separately. For optimal performance, the unit should be charged every 30 days when not in use. Once used, the unit should be charged immediately overnight.
