Abstract
The utility model discloses an emergency mobile power supply for handsets, which facilitates the emergency power supply operation for handsets. The emergency mobile power supply comprises a battery holder capable of accommodating three AA-sized batteries, and a USB connecting wire. The positive electrode and the negative electrode of the battery holder are electrically connected with the positive electrode and the negative electrode of the USB connecting wire respectively. Since the voltage of a circuit formed by the serial connection of three AA-sized batteries is 4.5V, the emergency mobile power supply can be used for directly charging a handset without any other complicated circuit boards. Therefore, the emergency mobile power supply for handsets has the advantages of simple manufacture, convenience and practicability.
Description
