Novel mobile power supply and preparing method thereof

Abstract

The invention provides a novel mobile power supply and a preparing method thereof. The novel mobile power supply comprises a charging battery and a circuit board; the circuit board comprises a battery protection circuit, a boosting circuit, a voltage stabilizing circuit, an MCU (microprogrammed control unit) control circuit, an electric quantity circuit and a USB (universal serial bus) interface; the battery protection circuit is connected with the charging battery, the boosting circuit and the voltage stabilizing circuit; the voltage stabilizing circuit is connected with the MCU control circuit connected with the electric quantity circuit and the boosting circuit; the boosting circuit is connected with the USB interface; the charging battery is a lithium iron phosphate battery with the capacity of 25A and the reference voltage of 2.5-3.6V. The preparing method of the novel mobile power supply comprises the steps of machining a circuit board, connecting the circuit board with the lithium iron phosphate battery, loading into a shell after the functional test of the circuit, and packing the finished product for storage after a full functional test. The mobile power supply is large in battery capacity, the charging capacity and charging times are greatly increased and the mobile power supply is very convenient to use outdoors for a long time.
