If you are facing charging issue for your Jabees Beebud. You may follow these instruction for troubleshooting.

Portable Charging Box (PCB) unable to charge fully.

There is one resistor in the PCB act as a protection to the battery, when the charging input is on higher current, this resistor will hold off the charging, preventing PCB to be charged fully. Please try with another AC charger.  

Earbuds unable to charge, no light.

Tried to clear the 3 charging point on the earbud itself using dry tissue or alcohol wipe. this issue will occur if any of the charging point is obstruct while trying to contact with PCB's charging pin.
