hi, jharker, thanks a lot for your reply, recently ,i have read a lot of words you wrote.
the battery icon is still white, I have charged for hours.
maybe there is something wrong with hardware. I have made a mistake,first time ,I take cathode as anode,the connect is totally wrong and the protectd card is overheat.
does it do harm to hardware? when I correct it ,it power on normally,
