How To Choose A Safer Power Bank Supply

How to choose a safer Power Bank supply?

How to choose a safer Power Bank supply? Whether you are in the subway or in your own room, using inferior Power Bank supplies will bring unimaginable consequences. In order to protect the lives of yourself and others, it is important to buy a good Power Bank supply.

From a safety point of view, the recommendations of Usun Technology for consumers to purchase Power Bank supplies are:

1. Buy the Power Bank supply produced by a manufacturer with product quality and corporate reputation. Do not buy low-priced fake products for cheap. Batteries and circuit boards have a certain fixed cost. The higher the quality of the battery, the higher the manufacturer's purchase cost, and the price will naturally be more expensive than the lower quality. More well-known Power Bank supply brands may have better product quality and better after-sales service.

2. It is best to choose polymer batteries for the Power Bank supply. The output efficiency of polymer batteries is relatively stable, and they are also light in weight, safe and efficient.

3. While considering the appearance of the shell, pay attention to the strength and heat resistance of the shell.

4. Don't blindly covet a high conversion rate. The conversion rate of the Power Bank supply is very important. If the conversion rate is too low, it indicates that the Power Bank line loss will be large, and it may generate heat and even cause an explosion. But the advertisement says that the conversion rate is as high as 90%, so be wary, because now the conversion rate is around 85% already very good.
