Now follow the below-given instruction to create your DIY charger successfully. 

  1. First, disassemble your Bluetooth speaker to take out the Printed Circuit Board (PCB). Be extra cautious during this process to not damage any internal parts, like input lines.
  2. Now, solder the two wires of the +5V on the PCB. 
  3. After connecting 9v on the emitter side, check whether your speaker is charging or not.
  4. If it's charging, tape the coil under the speaker's case and insert the PCB. After completing this step, restest your wireless charger.

Additional Tips: 

  • Make sure there is enough space inside the wireless speaker to fit the coil.

So play safe!

Consider Replacing The Battery
