Recharging From a Solar Panel
Small, unregulated 12 volt solar panels rated to produce a
maximum of 2.5 amps (or 30 watts) can be used to charge the
XPower Powerpack through the Charger Input Socket.
You will need to purchase a standard 5.5 mm OD x 2.5 mm
ID DC Coaxial (barrel type) connector to mate with the
Charger Input Socket.
To recharge with a solar panel:
1. Connect the solar panel’s red positive (+) wire to the
coaxial plug’s inner contact.
2. Connect the solar panel’s black negative (–) wire to the
plug’s outer contact.
Once the connector is inserted into the Charger Input
Socket and the solar panel is placed in the sun, the
XPower Powerpack charges automatically just as with
the AC Charger. See “Recharging with the AC Charger”
on page 27.
It takes about ten hours in direct sunlight to recharge the
XPower Powerpack from a 2.5 amp solar panel.

Battery Life
The high quality battery used in the XPower Powerpack will
serve as a reliable power source for years when properly
maintained.
To maximize battery life, it is important to recharge the
XPower Powerpack battery after each use.
Note: Battery Level indicators are only accurate when the
XPower Powerpack has been disconnected from all
appliances and all charging sources for fifteen minutes.
