Four-in-one mobile phone charging stand

Abstract

A four-in-one mobile phone charging stand including a stand body having a first charging groove for charging a specific type mobile phone in a vertical position and a second charging groove for charging or discharging one or two separable batteries in a horizontal position; a charging circuit positioned within the stand body and adapted to control the input DC current, the charging circuit having a first charging loop relative to the first charging groove as well as a second charging loop relative to the second charging groove so that either of them can be selected for performing the charging process; a DC TO DC voltage booster circuit coupled to the second charging groove for boosting the output voltage of the batteries in the second charging groove from 1.5˜3V DC to 4.5˜9V DC, thereby creating a third charging loop relative to the first charging groove; and a switching circuit adapted to control either the first charging loop or the third charging loop in such a way that the mobile phone in the first charging groove can be charged. Therefore, the mobile phone charging stand of the invention has the four functions of mobile phone charging stand, charger of secondary battery, non-stop charger, and the emergency power supply.
