Recharging the power pack battery
CAUTION: Do not operate DC appliance while the power pack is
being charged.
Charging with the AC charging adapter
Using the AC charging adapter is the simplest method for recharging the
battery. While charging from an AC source, the charging status LED indicator
will light red. When the battery has reached capacity, the indicator will light
green. Charging when the battery is fully discharged takes around 23 hours.
NOTE: Recharge the mobile power pack as soon as possible after each use.
When not used the power pack, it should be recharged every 3 months!
To recharge with AC charger:
1. Turn the rotary switch to the “OFF” position.
2. Plug AC charging adapter into charging jack on the front of the unit.
3. Plug AC charging adapter into 120V AC electrical outlet.
4. Continually charge until the battery is fully charged.
CAUTION: Full charging time for the unit assumes that there is 120V at the
AC wall outlet. If the voltage is less than 120V AC, it may require more time to
fully recharge the internal battery. Once fully charged, the charging current
automatically reduces to a floating charge mode, and the unit may be left
permanently connected to the AC charger.
