Method 2: Charge the speaker to fix not turning on issue

There are instances when the problem is caused by a fully drained battery. If this is the culprit then all you need to do to fix this is to charge the speaker.

  • Insert the USB-C charging cord  into the charging port of the speaker.
  • Insert the other end of the USB-C  charging cord to a USB wall charger with an output of at least 1.0A.
  • Connect the wall charger to a power outlet.

Leave this charging for at least 4 hours then check if the device will turn on.

Method 3: Faulty battery

If the 7500 mAh Li-ion battery of this Bluetooth speaker is defective and doesn’t have any charge anymore then you won’t be able to turn it on. The best way to proceed in this case is to replace the battery with a new one. It’s recommended that you have this done at a service center.

Some of the causes why a battery will fail is if it is constantly being overcharged or when it is always being exposed to heat. These factors will rapidly degrade the battery performance.

Method 4: Faulty circuit board

Even though this speaker has an IPX7 rating it is still possible for water to get inside it. If the circuit board gets wet then it will get damaged. If this is what’s causing the problem then you will need to have this fixed at a service center.

Having power issues on your Bluetooth speaker can be a frustrating experience. Hopefully, this solution will help you fix the problem.
