Description

A mobile power supply with dual storage channels

technical field

The utility model relates to a power supply system, in particular to a multifunctional mobile power supply.

Background technique

With the popularity of smart phones and other smart devices, smart electronic products have fully entered people's lives and work, which has greatly changed people's way of life and work. However, the current battery technology for smart electronic devices is still not able to provide an ideal technical solution with stable performance and long-term battery life, and the performance of most existing smart device batteries will decline significantly after long-term use, thus affecting the use effect , especially in inconvenient charging occasions. The current popular solution is to additionally equip mobile batteries to provide power supplements for power-deficient devices. In the mobile power solution of the prior art, the USB interface is usually used to charge the mobile power, and the mains power cannot be directly used for charging, which lacks flexibility in use.

Utility model content

In order to solve the power supplement problem of intelligent electronic equipment and further optimize the charging scheme of the mobile power itself, the utility model provides a mobile power supply with dual storage channels, which can charge the mobile power supply by using the mains power or DC charging mode at the same time.

The technical solution adopted by the utility model to solve the technical problem is that a mobile power supply with dual storage channels includes a casing, a battery, and a circuit board.

There is a battery in the casing, and the battery is electrically connected with the circuit board. The circuit board has a power storage interface and a discharge interface, and the two interfaces are electrically connected with the circuit board. There are AC folding pins on the casing, and the AC folding pins are electrically connected with the circuit board.

There are control switches and indicator lights, which are respectively electrically connected to the circuit board.

Preferably, the power storage interface adopts a Micro-USB interface, and the discharge interface adopts a USB-A interface.

Preferably, the casing includes a lower bottom box and a lower cylinder sleeved outside the bottom box. The battery and the circuit board are located in the lower bottom box, and the lower cylinder is set on the outside of the lower bottom box.

The beneficial effects of the utility model are: the AC folding pin and the power storage interface provide two charging modes, and the mobile power supply can be charged by the mains charging or the DC charging mode; the discharge interface can charge ordinary smart devices; the overall structure has a strong novelty and practicality.
