From The Manufacturer

With the STANLEY FATMAX J7CS 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 700 peak amps and 350 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. A high-powered LED light rotates 270 degrees to help you work in the dark. This jump starter is equipped with a 120 PSI air compressor to help inflate tires, sport equipment, or other items with low pressure. 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 FATMAX J7CS 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.
