There are two possibilities: the battery inside the charging treasure aging, charging treasure due to frequent charging and discharging, coupled with battery quality problems, it is easy to make the battery aging, storage performance is greatly reduced. The voltage of the battery can be measured using the voltage gear of the multimeter. If the voltage drops too fast after connecting the charging device, the battery is also damaged. The booster board is short-circuited, the booster board components are damaged, and there is a short-circuit phenomenon, which makes the self-discharge of the charging bank serious. The solution to the problem: Replace the battery. Repair or replace the booster plate.
There may be many reasons for the automatic power failure of Bex magnetic charging treasure, the following are some common reasons:
1. The phone is nearly full, and the power bank will cut off the output when it detects that the output current is relatively small;
2. Power bank output protection, power bank output circuit, data cable or mobile phone interface short circuit, power bank output protection, cut off the output;
3. Cell phone battery circuit problems.
