How do I charge the drive?
JA-02 II has a built-in lithium battery, you can charge it with the connected USB Type-C charging cable. When the battery is low enough, JA-02 II will turn off
automatically down. Remember to charge it in time, the battery will lead to irreversible loss of battery capacity for a long time. Please note:
The power indicator shows the charging status only when it is off, the power indicator is on and red under normal use.
The power indicator is yellow when turned off and charged, the power indicator turns off when fully charged.

Note: JA-02 II only has one USB Type-C charging cable included, you can use any 5V charger. If you are not sure which
One is right, use the charger of the smartphone to charge. Please make sure the rated output current of the charger is ≥ 1A. (Almost all smart
Phone chargers meet this requirement.)
Note: Since it has a built-in lithium battery, do not disassemble JA-02 II.
