Important: The 24-hour charging time for the XPower
Powerpack assumes that there is 120 V AC at the AC wall outlet.
If the voltage is less than 120 V AC, it may take more than 24
hours to fully recharge the XPower Powerpack. If, after 24 hours
of charging, the Battery Status LED remains red, continue to
charge the unit for another 12 hours. The unit will be ready for use
even if the Battery Status LED remains red.
Important: If you keep the XPower Powerpack in storage, the
battery will self-discharge over time. Remember to recharge the
battery every three months to keep the XPower Powerpack

reduces to a maintenance charge mode, and the XPower
