The classification of the power bank

Power Bank is the popular name of mobile power and there are currently numerous brands in the market. Therefore, some people may pose some problems to decide which is the best power bank for smartphones. And knowledge of the power bank categories can serve as a hand to make the purchase decision.

Classified by capacity

In general, most power banks can be divided into 3600mAh, 5000mAh, 10000mAh and 20000mAh. The biggest difference between them lies in the capacity of the battery, which leads to different times of giving full power to the cell phone.

To help you better understand the concepts, we can take 10000mAh, for example. You can fully charge our 2-3 mobile phone times. And the power banks whose capacity does not exceed 1000mAh can be taken to the plane. So this specification is suitable for most people.

Sorted by Appearance

We can see many styles of power bank in the market, such as the rear clip style, which can also serve as a case for smartphones and is easier to use during charging, since there is no cable. Those with cable may be the most common style of power bank.

And there is also a model called fast two-way charging, which means that the power bank itself can be charged when charging the cell phone, which saves a lot of time.

In addition, the mini power bank, as well as the magnetically charged mobile power, is also popular. The latter is the new recent Power Bank model, which is smaller and easier to carry out. And more importantly, you can not only charge the mobile phone, but also the smart watch, etc.

Classified by interface

Normally, there is a USB port and a type C port for the power bank. It is relatively simple to choose, since you only have to choose the one that is suitable for your own cell phone port. And many power banks now have multiple interfaces, which is more convenient.

Rated by loading speed

Power banks can be divided into fast and normal charging speed and the main difference is the input and output power. The higher the power, the faster the load.

Most of the power banks after the update have adopted a new charging protocol. Like the data cable, whose input is 5V / 3A, 9V / 2A and 12V / 1.5A belong to the fast charging type. The output power is the same as the input. This can also serve as an explanation of why some power banks can charge quickly while others cannot.

Classified by function

If it is categorized by function, there is the ordinary and the intelligent. The ordinary can only load and unload, and tend to have a fixed output current, so the function is silent.

While its smart counterpart is able to accurately display the power and automatically adjust the battery according to the device. As the era of intelligence approaches, it is also necessary for the power bank to be intelligent.

4 Tips for choosing Power Bank

For a world in motion, it is imperative to ensure that your devices remain charged for a day of constant use. If you know what specifications to look for, research and get all the notices, so here we will tell you how to choose the right power bank for you and keep your devices charged for as long as you want.

1. Conversion Rate

The conversion rate has a lot to do with battery capacity. The higher the battery capacity, the lower the conversion rate and the visa verse. If the battery capacity is small and the conversion rate of the electric card is high, you can charge cell phones more times.

The overall conversion rate is approximately 85%, and if it is above 90%, it is most likely misleading.

On the other hand, if the conversion rate is less than 75%, it can be considered as a lower power bank.

2. Compatibility

It is advisable to choose one with high compatibility and it is better to choose a power bank with data cable in case we forget to bring one.

3. Charging method

Compared to the linear power bank, it is preferable to select the pulse charging mode that allows a large charging current and a low charging temperature and a long battery life. However, the premise is that there is cargo protection, otherwise it will be dangerous.

4. Weight

The capacity of the power bank is proportional to its weight, which means that the larger the battery capacity, the heavier it is. If you only charge it once a day, a 3000-5000mAh is enough.

Since today we cannot live without a power bank, it is of great importance to have some knowledge of it and know how to select the power bank for the mobile phone. Hopefully, the above tips can help you make a profitable decision and give more comfort and enjoyment to life.
