Recharging the XPower Powerpack Battery
30
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 centre positive)
connector to mate with the AC Charger Input Socket.
To locate this part, search on the Internet for 5.5 mm OD ×
2.5 mm ID plug for AC adaptor barrel-type coaxial plug for
use with Universal AC Adaptors, or contact a consumer
electronics parts store with this description.
To wire the coaxial DC connector:
1. Connect the solar panel’s red positive (+) wire to the
coaxial plug’s inner or centre 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 26.
It takes about six hours in direct sunlight to recharge the
XPower Powerpack from a 2.5 A solar panel.
