Abstract

A portable multifunctional power bank device includes a built-in battery, a protection circuit, a charger, a DC to AC Inverter, and a LED lighting circuit. The built-in battery provides a Direct current. The protection circuit is connected to the built-in battery to control charging and discharging. The charger is connected to the built-in battery, wherein the charger has an input terminal connected to a Mains power supply, and the Mains power supply charges to the built-in battery through the charger. The DC to AC Inverter is connected to the built-in battery, wherein the DC to AC Inverter has an input terminal for inputting an Alternating-current. The LED lighting circuit is connected to the built-in battery to supply power to the LED lighting circuit.
