Abstract

The invention provides a mobile phone lithium battery emergency charger, which is characterized by comprising a 3V battery pack, a self-excited oscillation circuit, a positive feedback circuit, a voltage stabilizing circuit and a mobile phone lithium battery charging loop, wherein the self-excited oscillation circuit consists of a NPN type tirode VT1, a high-frequency transformer T1, a starting resistor R1, a resistor R2 and a capacitor C2, the positive feedback circuit consists of a high-frequency transformer T1 feedback coil L2, a capacitor C2 and a resistor R2, the voltage stabilizing circuit consists of a voltage stabilizing diode DW, a switch diode D1, a resistor R3 and an electrolytic capacitor C1, the mobile phone lithium battery charging loop consists of a Schottky diode D2, an electrolytic capacitor C3, a resistor R4 and a charging output terminal. In order to solve the emergency use problem of a mobile phone lithium battery, the mobile phone lithium battery emergency charger realizes the emergency charging by using two sections of AA batteries or rechargeable batteries.

Description

technical field [0001] The invention belongs to the technical field of mobile phone battery charging, and relates to an emergency charger for a mobile phone lithium battery. Background technique [0002] With the multi-functional development trend of mobile phones, the power consumption of mobile phones has also increased significantly, which puts forward higher requirements for batteries, but on the other hand, batteries are becoming more and more Smaller and thinner, but the battery power supply technology has not changed fundamentally, which brings about the problem of reduced standby time. Occasionally, when it is necessary to make a call, all communication information cannot be called out due to the lack of power of the mobile phone. This special situation is really helpless, and it brings certain troubles to people's use of mobile phones. In order to solve this problem, many people adopt the configuration scheme of dual batteries and double charging when purchasing mo...
