B. About Power Bank battery
Make sure your PBC-20 is fully charged on its first use.
When recharging your PBC-20 or charging a device with your PBC-20,
make sure you use a standard charging cable (USB to micro USB).
If all indicators go off when charging a device with your PBC-20, recharge
your PBC-20 shortly.
Disconnect the PBC-20 case to avoid further discharge once your device is
fully charged.
Note:
The PBC-20 contains a built-in temperature monitor sensor. If it measures
that the battery pack temperature is outside acceptable limits it will
control and stop the charging function. The charging function will be
automatically restored when the detected battery pack temperature
returns to within normal limits.
C. Charge Power Bank case
Plug the Micro USB connector of the cable into the PBC-20 input port and
the other end into a USB power adapter (not included), or USB-A port on
your laptop computer. The indicator lights will flash and then stay on solid
one by one as the charging progresses.
