Multi-source charger

Abstract

The invention provides a multi-source charger, which has a box body, wherein the upper side of the box body is provided with an illuminating lamp and a Mini USB interface; the lower side of the box body is provided with a standard USB interface; the left side of the box body is provided with a power indicating lamp and a press handle; the right side of the box body is provided with a DC input interface, a handle clamping lock and an AC rotary input interface; a generating device, a control circuit board and an built-in energy storage device are arranged inside the box body; the generating device is connected to the press handle; and the illuminating lamp, the Mini USB interface, the standard USB interface, the power indicating lamp, the DC input interface, the AC rotary input interface, the generating device and the built-in energy storage device are both connected to the control circuit board. The multi-source charger provided by the invention can convert AC commercial power or a dry battery into standard power so as to be output, generates power by use of the built-in energy storage device or manually when no external power source exists, is used for supplying power to mobile equipment or charging 3.7V standard lithium batteries, is suitable for all mobile equipment holders, and can charge the mobile equipment or the 3.7V standard lithium batteries under the circumstance with or without a power source.

Description

Technical field: [0001] The invention relates to a mobile device power supply device and a device for charging a 3.7V standard lithium battery, in particular to a multi-source charger. Background technique: [0002] With the rapid development of the digital product market, portable mobile devices such as mobile phones, MP3, MP4, and digital cameras are becoming more and more popular, and their supporting chargers are also changing rapidly. The existing technologies and products can no longer meet the needs of the market. Therefore, there is an urgent need to develop new products and new technologies to improve the existing situation. [0003] Most of the existing chargers are standard chargers with mobile devices or universal chargers, both of which have their own advantages and disadvantages. [0004] The quality of the standard mobile device charger is good, and the functional parameters match the product specifications. However, the design specifications and circuit comp...

AI Technical Summary

Problems solved by technology

[0004] The quality of the standard mobile device charger is good, and the functional parameters match the product specifications. However, the design specifications and circuit components used by each manufacturer are different, resulting in differences in interfaces, output parameters, etc., or a manufacturer’s charger can only It is not versatile for the products produced by the factory. Once the product is scrapped or lost, the charger will also be scrapped, resulting in a huge waste. At present, there is still a blank in the waste recycling of chargers in China. They are all disposed of in a discarded manner, but such products often contain heavy metal components, and random discarding will cause serious pollution to the environment

[0005] Although the universal charger currently on the market has a wide range of applications and can charge the standard battery, its structure and circuit are very simple, and it cannot correctly detect and judge the overcharge and undercharge of all batteries. It will cause damage to the battery and affect the service life, and after the battery is damaged, its internal structure will change, and continued use will cause great safety hazards

[0006] Whether it is the original charger or the universal charger, it is generally charged after converting the AC mains power. If there is no AC mains connection on the vehicle or ship during the trip, the product cannot be charged.
