Abstract
The utility model discloses a portable mobile phone charger which comprises a dry battery, a charging main circuit and a connector assembly, wherein the dry battery is used for providing charging current. The portable mobile phone charger is characterized in that: the anode of the dry battery is connected with an input end of the charging main circuit; the connector assembly is provided with three output end points which are not conducted with each other; a resistor R, a grounding end of the charging main circuit and the cathode of the dry battery are respectively and electrically connected with the three output end points; and a transformer is arranged between the cathode of the dry battery and the third output end point. The connector assembly is provided with the three output end points which are not conducted with each other, so that the cathode of the dry battery is conducted with the grounding end of the charging main circuit only when plug-in switches are inserted into the connector assembly, or else, the cathode of the dry battery is not conducted with the grounding end of the charging main circuit, so that any static work current is not generated; but an LED (Light Emitting Diode) lamp can be used for conducting switchover with the charger so that operation can be carried out under darker light.
Description
[technical field]
The utility model relates to charger for mobile phone, relates in particular to a kind of small-sized portable telephone charger, and this charger can replenish the energy to mobile phone under the situation of outdoor no civil power.
[background technology]
Mobile phone is as a kind of universal communication tool, the effect of playing in life and work is more and more important, and one one of staff is carried basically, and the busy personage of commercial affairs uses and frequently causes the follow-up nothing of mobile phone easily, can give cell-phone charging at any time, could conveniently feel at ease to use.Existing charger generally all is directly to connect civil power alternating current is converted into direct current gives cell-phone charging then, and this is adapted at family or uses in office, in case go out external or just be difficult to the mobile phone electric energy supplement in public.
Wish to propose a kind of mobile energy storage charging device, can both give cell-phone charging at any time in any occasion, keep mobile phone unimpeded, can not have influence on important affairs because there not being electricity.In addition, owing to may charge to mobile phone, preferably this portable energy storage charging device had more convenience designs in the open air.
[summary of the invention]
