Recharging the XPower Powerpack Battery

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 AC charger Input socket.

You will need to purchase a standard 5.5 mm OD × 2.5 mm ID (0.217 × 0.10") coaxial DC (barrel type center positive) connector to mate with the AC charger input socket.

To wire the coaxial DC connector:

1.Connect the solar panel’s red positive (+) wire to the coaxial plug’s inner or center contact.

2.Connect the solar panel’s black negative (–) wire to the plug’s outer contact. See Figure 4-1.

Once the connector is inserted into the AC 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 28.

It takes about six hours in direct sunlight to recharge the XPower Powerpack from a 2.5 A solar panel.
