The magnetic attraction of the wireless charging belt will have an impact on charging, mainly depending on the location and strength of the magnetic attraction. During the charging process, if the magnetic device overlaps with the coil position of the charging bank or charging device, the charging efficiency may be affected and even the charging failure may be caused. In addition, too strong magnetic attraction may also cause coil dislocation or damage, which will affect charging. Therefore, when purchasing a wireless charging bank, it is recommended to choose a product without magnetic function to ensure charging effect and safety.
