Charge Long Time

Please replace the charger and use the Quest 2 charger and cable, or a charger that supports DC5V2.6A-5V3A. Charge the B2 separately for 3 hours, and then observe the actual battery level.

If replacing the charger and charging cable does not solve the issue, please provide the following information:

  1. A video showcasing the problem you are experiencing.
  2. An order invoice that includes product information and order number.

Please send these to our after-sales support email at so that we can better assist you in resolving the issue and providing after-sales support.
