Magnetic charging banks may charge more slowly than other charging methods. Magnetic charging bank is usually connected to the charging device by magnetic adsorption, which may have a certain energy loss when transmitting electric energy. In addition, the magnetic charging bank may also be limited by the power of the charging device, resulting in a slower charging speed. If you feel that the charging speed is too slow, you can try to change to another charging method or use a higher power charger to speed up the charging speed.
