    Now most of the power bank is equipped with a fast charge head, in the case of using a fast charge head, the charging speed of the power bank is still very fast. If you take a regular 5W charger and charge it, it's going to be very slow. And it is particularly easy to be full of electricity, but the number of times used is very small, which proves that the mobile power is charged with virtual electricity. Therefore, when charging the power bank, it is recommended that we choose the fast charge head.

    In addition to the problem of not using fast charging head, the second most likely reason is that the power bank itself has quality problems. If you use it completely in accordance with the instructions, but the charging speed is still very slow, then it can only show that the power bank itself has quality problems. At this time, we can replace the charging cable and try to charge. If all the charging lines make the power bank charging slow problem. Then there must be something wrong with the cell of the power bank.
