1, the charging treasure is damp, if the charging treasure is not stored in a dry place, the charging speed will be affected after the moisture, so pay attention to the preservation of the charging treasure.
2, the voltage is too small, such as the charging head is not selected, if the charging head itself output voltage is very low, then it will also affect the power of charging, it is recommended to choose 5v charging head.
3, the use of the original data cable, generally buy a charging treasure will have a data cable, this is the most suitable with the charging treasure, with this is certainly no problem, if not, you can also choose the charger that usually charges the phone, try to choose a high output power charger.
4, the capacitor or circuit in the charging bank is broken, this situation has to be taken to repair, there is a warranty, of course, better.
power bank
Mobile power supply, mobile charger (line power, line charge, charging bank, urine bag, wet nurse;) It is a portable charger that can be carried by an individual and can reserve electrical energy itself, mainly for handheld mobile devices and other consumer electronic products (such as wireless phones, laptops) to charge, especially in the absence of external power supply.
Its main components include: a battery used as energy storage, a circuit that stabilizes the output voltage (DC-DC converter), and most mobile power supplies have chargers that are used as built-in batteries for charging.
The solution is to replace the electrolyte of the charging treasure, after the electrolyte concentration decreases, the pure electric capacity decreases, so the charging treasure can not be charged normally, and it needs to be replaced in time
