CHARGING
Prior to first use, the battery should be charged for at least 6 hours using the included AC
power adapter. Alternatively, it can be first charged for at least 12 hours using compatible
solar panels (not included). Additionally, the battery should be fully charged after each use
and at least once every three months to prevent damage to the battery.
AC Power Adapter
Perform the following steps to charge the
battery using the included AC power adapter.
1. Plug the DC barrel connector on the
included AC power adapter into one of
the Charging Input Ports (10) on the
Power Cache 220.
2. Plug one end of the included AC power
cord into the AC power adapter, then
plug the other end into a nearby AC power outlet. The Charging Input LED Indicator
(2) will glow Red and the LCD Display (1) will blink the current charge level.
3. When charging is complete, the LCD Display (1) will show a full charge and the
Charging Input LED Indicator (2) will change from Red to Green.
4. Unplug the AC power cord from the AC power outlet, then unplug the AC power
adapter from the Charging Input Port (10).
Note that while charging is in progress, the AC power adapter may become warm
to the touch. This is normal.

in position to capture solar energy.
2. Plug the DC barrel connector on a
compatible solar panel (not included)
into one of the Charging Input Ports (10)
on the Power Cache 220. If the solar
panel is capturing energy, the Charging
Input LED Indicator (2) will glow Red
and the LCD Display (1) will blink the
current charge level. If using two solar
panels, repeat the process to connect
