Mobile phone charger employing dry battery

Abstract

The invention discloses a mobile phone changer charging a mobile phone with a dry battery. The mobile phone charger mainly comprises a dry battery, a DC / DC voltage booster circuit, a voltage set circuit, an output control circuit and an input interface and adapter cables matched with the output interface, wherein the output control circuit is formed by parallelly connecting an old-standard output circuit and a new-standard output circuit, and the output interface is matched and connected with an old-standard adapter cable and a new-standard adapter cable. The old-standard output circuit is formed by connecting a chip resistor, a field-effect tube and a resettable fuse. The new-standard output circuit is formed by connecting a chip resistor, a field-effect tube and a resettable fuse. The old-standard output circuit and the new-standard output circuit are parallelly connected with the output interface formed by a mini USB socket. The old-standard adapter cable and the new-standard adapter cable are mini USB adapter cables matched with the mini USB sockets. The mobile phone charger has the characteristics of meeting charging needs of new and old-standard mobile phones, along with simple structure, convenient use, high battery energy conversion efficiency, high battery utilization rate and so on.

Description

technical field [0001] The invention relates to a charging device for a mobile phone, in particular to a device for charging a mobile phone with a dry battery. Background technique [0002] In modern life, mobile phones, Mp3, handheld computers, digital cameras and other digital products are used more and more frequently, and AC-powered chargers can no longer meet people's charging needs in special occasions. The mobile phone emergency charger powered by dry batteries is small in size, easy to carry and easy to use, so it can solve the charging problem of mobile phones and other digital products when people are in the field, on the road or in other places far away from AC power supply places. However, the existing mobile phone emergency chargers can only basically meet the needs of mobile phone emergency charging, and there are still shortcomings such as short charging time, low battery utilization rate, and insufficient versatility of the conversion interface. Especially a...

However, the existing mobile phone emergency chargers can only basically meet the needs of mobile phone emergency charging, and there are still shortcomings such as short charging time, low battery utilization rate, and insufficient versatility of the conversion interface.

Especially after the country implements the new standard of mobile phone chargers, the mobile phone chargers charged with dry batteries on the market at this stage can only charge the old standard mobile phones, and cannot charge the new standard mobile phones, which brings great inconvenience to users.
