Portable power bank is also called "external battery", "backup battery" and "digital charging partner". The concept of the portable power bank is developed with the popularity and rapid growth of digital products, and its definition is convenient and easy to carry a large capacity portable power supply. The functions of digital products are increasingly diversified and used more frequently. How to improve the use time of digital products and give full play to their maximum functions is becoming more and more important. the power station supply is the best solution to solve this problem. With a power station, you can provide power (power supply or charging) for a variety of digital products anytime and anywhere in the mobile state.

    The capacity of the portable power bank varies from 2000 to 20000 MAH, generally, more than 18000 MAH of energy can be used to power laptops, generally called universal mobile power. Less than 10000 capacity, generally smaller, are called portable power banks, mainly used to charge digital products.

    How to use a portable power bank?

    a. The output voltage of portable power bank should be 5.3v ± 5 V, otherwise, it can't charge some brands of mobile phones;

    b. The transfer connector must be matched. The principle of using power station products is to charge the digital devices through a USB cable. One end of the cable with a USB interface is connected to the Portable power bank, and the other end is connected to the digital devices. Therefore, the interface of the other end must be consistent with the interface of the digital devices, otherwise, it cannot be charged.

    c. Portable power bank should be handled in a dry environment. Rain, moisture, and various liquids or moisture can corrode electronic components and circuits.

    d. Portable power banks cannot be stored at high temperatures. High temperatures will shorten the life of electronic devices, damage batteries, and age some plastics.

    e. It is not allowed to throw or knock the power station supply in a rough way. Rough use may damage the internal circuit board and precision machinery.
