Recharging the XPower Powerpack Battery
975-0218-01-01 35
Recharging From a Solar Panel
Small, unregulated 12 V solar panels rated to produce a
maximum of 2.5 A (or 30 W) can be used to charge the
XPower Powerpack through the Charger Input Socket.
You will need to purchase a standard 5.5 mm OD × 2.5 mm
(0.217" × 0.10") ID DC Coaxial (barrel type) connector to
mate with the Charger Input Socket. This type of connector is
available at consumer electronics stores.
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 31.
It takes about ten hours in direct sunlight to recharge the
XPower Powerpack from a 2.5 A solar panel.
