Although the vast majority of smart electronic devices are equipped with built-in lithium batteries without the need to purchase additional batteries, most devices still need to use No. 5 or No. 7 batteries. Like the author's wireless mouse, wireless keyboard, calculator, home remote control, etc. Non rechargeable alkaline batteries or carbon batteries are disposable in use, which is neither environmentally friendly nor convenient. This time on Love to play computer games Get the opportunity to experience Shuerbo USB rechargeable lithium battery that can be recharged circularly, environmentally friendly and convenient. I believe this gift can perfectly solve the power supply problem of wireless mouse and other products that I encounter in my life.

This time, the author obtained Shuerbo rechargeable battery No. 5. The battery is much more practical and convenient than the traditional battery in terms of external packaging. Many traditional disposable batteries are packed in plastic paper and can no longer be used after being opened. The USB battery of Shuerbo is packed in a hard plastic box. The package can be recycled. If the battery is not used temporarily, it can also be temporarily stored in the package to prevent loss.

There is also a layer of paper box on the periphery of the hard plastic box package. The main parameters of the product can be seen from the paper box: 1.5V standard voltage; The capacity is up to 1200mAh, which can make the equipment use longer; It takes about 1 hour to 2 hours to charge.

Open the package, you can see a total of four No. 5 batteries lying in the package. In terms of packaging accessories, the No. 5 battery I received is just four batteries, and there are no other accessories. Since the charging interface of No. 7 battery is on the side of the battery, there is a charging wire attached to No. 7 battery.

Compared with No. 7 battery, which needs to be connected and charged by wire, No. 5 battery is more convenient. Just open the yellow cover of the positive pole of the battery to see a USB interface. Connect it to the charging head to charge the battery.

In addition, the place where the yellow cover is connected to the battery is designed to be transparent. At first, the author did not understand the reason for this design. Later, when charging, he realized that this design is because the indicator light effect will be displayed here when charging the battery.

The indicator light can be divided into two forms: red and green. Red indicates that the battery is not fully charged, while green indicates that the battery is fully charged. In addition, since the lithium battery has no no memory effect, it does not need to wait for the battery to run out of power before charging and so on. You can charge the battery as needed.

In addition to supporting cyclic charging, Shuerbo battery has the advantage of supporting fast charging. After the author got it, he charged it, which took about an hour, and the other two took several more than ten minutes. It can be seen that the charging and discharging performance of the USB charging battery of Shuo Erbo is very stable.

In fact, No. 5 and No. 7 batteries have a wide range of applications. For example, the remote control at home is usually a No. 5 or No. 7 battery, as well as a clock at home. I got a remote control, but I used No. 7 battery instead of No. 5 battery.

Fortunately, the Xiaomi wireless mouse that the author often uses is battery 5. In this way, the author will no longer have to worry about buying batteries when the mouse battery runs out.

In addition, for financial workers, Shuo Erbo USB battery should be more practical. Like calculators that are often used, they usually use two or even four batteries, and the battery consumption is also very open. The problem can be solved by using Shorebo batteries.

The USB rechargeable battery of Shorebo has a wide range of applications. It is portable, recyclable and supports fast charging. It can not only protect the environment and save energy, but also solve the problem of power supply for digital devices in people's lives, killing two birds with one stone. Moreover, the price of Shuo Erbo battery is not very expensive. It is recommended to prepare a set in the family so that you don't have to worry about the power loss of the remote control.
