In recent years, there have always been a lot of negative news about power bank, such as natural explosion and other problems. Therefore, consumers are less and less confident in power bank. When choosing a lover, they are always hesitant, but consumers do not know that the core part of power bank is the battery core. If once the cell has a quality problem then can appear these terrible safety problems. So we are going to analyze today, in the end how to distinguish the power bank core is good or bad.

    At present, only by using professional testing tools can you distinguish the quality of power bank core products, but if you have a certain basis for electronic products, then you can try to check whether the anti-wear surface of the core is uniform, there is no brittle crack appearance without burr to judge the quality of the core.

    So for the rest of us, we can only judge from the battery sign. We can identify the basic situation of the power bank cell from the battery type, type, rated voltage, standard voltage, and the name of the manufacturer of positive and negative poles. But if you don't have a basic knowledge of electronics, please don't try to independently disassemble the power bank supply, this behavior is very dangerous.

    In the process of use, we can also through the power bank supply whether there is abnormal heat, smoke, shell uplift, easy to disconnect charging, large capacity but discharge time is very short phenomenon to distinguish, because once these problems appear, basically can judge your power bank core is a problem. And the most important point is also the most straightforward point, look at the price of the power bank supply you buy, if dozens of pieces you can buy tens of thousands of capacity of power bank supply, it is best not to buy this product, because this is basically the existence of the virtual mark problem, then the quality of its cell must be not pass the standard.

    So in the selection of power bank supply process must be bullish about its relevant data, at the same time to identify the cell is good or bad, so we must pay more attention to the temperature, discharge time, etc., in use, to judge whether it has the above safety problems.
