Run a full charge/discharge cycle at least once every 4 months to
avoid shortening the life span of the internal battery.
If long term storage is likely to occur between uses, we
recommend storing Power 144 at approximately 50% full.
The USB and LED control circuit needs to sense at least a 1W load
to stay energized, otherwise it will turn off to save energy. If
powering a very small load, it may be necessary to turn on the
white LED light (double press on power button) to keep the USB
output energized. The LED draws approximately 2W from the
battery so there will not be a significant battery drain.
Using your Powerbank in temperatures below 0C or above 40C is
highly inadvisable and may damage the internal battery. Under
no circumstances should you charge the Powerbank if it is below
freezing. Allow the Powerbank to warm up before charging.
