Recharging
Recharge every 30 days and after each use. Failure to do so will result in possible damage to the internal battery and result in poor performance or failure to work at all.
1. Plug the AC Charging Cord supplied into the 120 Volt-in connection on the back of the Jump Pack.
2. Plug the other end of the cord into a 110/120-volt AC outlet.
3. The Red charging LED light will glow and will remain ON during the charging process When the internal battery is completely full the Green FULL CHARGE LED light on the control panel will turn on automatically. This can take up to 72 hours depending on the condition of your internal battery. You can unplug your AC Charging Cord at this time OR leave it plugged in indefinitely as the CUL™ listed internal charger is float charge equipped to maintain the internal battery
