Although rechargeable lithium batteries are very popular nowadays, the traditional No. 5 or No. 7 batteries are still used on some special devices, such as game consoles, remote controls, Bluetooth mice, etc. The traditional dry batteries have to be thrown away when they are used up, which is wasteful and not environmentally friendly. However, those traditional rechargeable batteries need special chargers (there are too many chargers now). Because of this, USB rechargeable lithium battery with the shape of traditional dry battery came into being.

From the appearance, this kind of battery is the traditional No. 5 battery, which is also used by most devices now. In other words, it can be used in many electronic and digital devices that need batteries. The appearance of No. 5 dry battery, USB charging plug and built-in lithium battery are really a good combination.

I have been exposed to some traditional No. 5 rechargeable batteries before. Many batteries have a single capacity of more than 2000mA, and the service time will be relatively long.

The capacity of Schreber is 1200MA. Why is the capacity relatively small?

I'll talk about it later.

Four batteries are one piece, and a clinker box can be used for both packaging and storage. I also need to take such things with me on business trips. In fact, I wrote it when I was on business trips, and I also took the battery with me. The MagicMouse I usually use actually uses a No. 5 battery, which is convenient to carry and charge.

There is a clear boundary in the appearance design of the battery, which is very similar to many ordinary dry batteries today, but different from the decorative role of many ordinary dry batteries. Here, Shuo Erbo designs a USB plug protective sleeve and acts as the positive pole of the battery.

The cover is connected to the main body with a rubber band, which is not too elastic, so it is easy to pull apart. The length is slightly longer than the USB plug, so it will not hang too long when charging.

There is a metal contact on one side of the rubber band under the cover, which is used to connect the positive pole of the electric core. Is there any poor contact in this design? Of course not, because the cover of the battery is tightly pressed when it is used, and there is no accident after several days of use.

The bottom battery cathode is the same design as most batteries, and there is nothing to say.

There is a transparent plastic ring between the cover and the battery body. Here is the battery charging indicator, which displays red when charging, and green when the battery is fully charged.

The official charging time of Shorebo is about 1 hour. According to the actual test, the 5V voltage+0.4A current is not very powerful. However, considering the volume of a single battery and the actual use scenario, this battery is not suitable for fast charging with high power. First, small size is not suitable for high-power charging circuit; Second, in order to facilitate me to use the computer for direct charging, the power of the computer USB will not be too large, and it is meaningless to design too large. In addition, four batteries are available at a time, which is better and convenient for standby.

I use a lot of battery equipment. I often buy ordinary dry batteries for use, and throw them away after use. I feel that they are wasteful. However, there are quite a lot of equipment. Four batteries are not enough. We should start more in the future.

summary

In terms of battery capacity, it is naturally inferior to many traditional rechargeable batteries, but its convenience and usability are not comparable to those batteries. In my personal use scenario, the power consumption of the device is not very fast. Anyway, it has not been recharged for nearly ten days since the start of use, and the power is still sufficient. It's OK to take the battery with you when you go out, and you don't need the heavy charger. The compatibility of charging mode is its advantage. It's really convenient to use when you go out.
