Yes. If all four lights on the mobile power supply flash together, it means the motherboard is broken. If only one light keeps flashing and cannot be charged, it means that the mobile power supply has entered the charging protection state. Once the motherboard is fried, the power LED may flash abnormally. When the mobile power supply is overloaded or the charging voltage is too high, the mobile power supply will enter the charging protection state. At this time, it will not be charged. Plug the mobile power into the computer's USB output port and. charge for 2 hours to release the charging protection state.
