When charging via PC connection, the charge time may
change depending on whether the device is On or Off.
The maximum charge time with a 5V 2A charging adapter is
4 hours and 30 minutes. (Fully discharged battery, power Off)
If the device is On and/or being used while charging, the
charge time may be longer or the battery may not fully
charge. Charging with the device turned Off is recommended.
The device may not charge if the PC or USB connection
goes into standby/sleep mode.
The device may charge slowly or not charge at all in
extreme temperatures. Charging in a room-temperature
setting is recommended.
The built-in battery will gradually lose capacity over time
according to the number of charges/discharges.
Be sure to use a high-powered USB 2.0 port. A low-
powered USB port (i.e. keyboard or USB hub without a
dedicated power supply) will increase the charge time.
Do not use a Micro-USB cable other than the one supplied
with the device because doing so may cause a malfunction.
