follow up below step for charging.

        USB charger (USB adaptor or USB output port like on PC, USB rating output: 5V/1A, other 
        USB charger with current equal or above 1A). The micro USB connector should connect 
        with the DC 5V power jack on the rear panel of speaker, and the another terminal connect 
        with USB charger. Then plug your USB charger on household AC power.

        when the battery is fully charged.

Important:

 We recommend connect the USB charger with rating output spec at DC 5V/1A, or 

equal  or  above  1A  output  current  USB  power.  The  general  USB  output  on  PC  (personal 
computer)  is  5V/1A  (please  reference  your  PC  spec  for  checking).  There  may  have  some 
charging  noise  or  abnormal  function  from  speaker  if  the  charging  current  is  too  low.  If  it 
happened,  please  remove  the  charging  power  and  put  the  speaker  in  a  while,  then  the 
speaker will reset the function in normal. Please kindly note this is not malfunction.
