This is because of the reason of the charging treasure, the insufficient output of the charging treasure meets the charging current of the mobile phone, and the chip overheats and starts overload protection after 1 minute. You can restart it with a new charge, but it will still charge and then power off.The solution is to change a thin data cable, preferably one with an iron core. In this way, the charging current will be reduced, the charging time can be extended, and even the charging bank will no longer start overload protection.Expand Answer:The charging bank is actually a large capacity portable power supply that is convenient and easy to carry. It is a portable device that integrates power storage, voltage boost and charge management. The charger's own charging plug can charge mobile devices directly through the AC power supply and has its own storage device, equivalent to a hybrid of a charger and a standby battery, compared with the standby power supply can simplify a charging plug device, and compared with the charger it has its own storage device, can provide backup power to digital products when there is no direct power supply or when going out.
