A sheet-shaped insulating plate 13 is arranged between the battery pack and the circuit board to prevent the circuit board from being conductive due to the fact that the circuit board is close to the positive and negative pole pieces of the single battery. It should be noted that the insulating plate may not be provided when the circuit board and the pole piece of the battery are far enough away from the pole piece of the battery to not affect the circuit board.
Referring to fig. 7, in this embodiment, the interface 201 of the universal mobile power supply includes 3 independent interface units, which are a charging interface unit 15, a first discharging interface unit 17, and a second discharging interface unit 19, respectively, and are disposed on the circuit board 300. The charging interface unit 15 can be connected with a charger, the charger is connected with a power socket on a wall, and when the universal mobile power supply is insufficient in electric quantity and needs to be charged, the universal mobile power supply is charged through the charging interface; the first discharging interface unit 17 is connected with an external portable electronic device to supply power to the portable electronic device, a corresponding interface unit is arranged outside the portable electronic device, an energy storage unit and a working circuit are arranged inside the portable electronic device, the energy storage unit supplies power to the working circuit, when the portable electronic device is connected with the universal mobile power supply, the universal mobile power supply can charge the energy storage unit inside the portable electronic device, and when the portable electronic device is not provided with the energy storage unit or a user chooses not to charge the energy storage unit, the universal mobile power supply can directly supply power to the working circuit; the second discharge interface unit 19 can output the electric energy required by the electric tool to supply power to the electric tool.
