How do I charge the EverStart Jump Starter 750 Amp?

Lift the protective cover of the built-in 120 Volt AC Charger, connect an extension cord to the unit, and plug it into a standard 120-volt AC wall outlet. Charge for approximately 24 hours or until the Battery Status Icon shows 4 solid bars. When charging is complete, unplug the AC extension cord from the outlet and then disconnect it from the unit.
