1. No wireless charging. 2. This is because the wireless charging bank needs to establish electromagnetic induction coupling with the charging device to transmit energy through the electromagnetic field.
However, the wireless charging banks currently on the market can usually only be connected to the power supply through a wired way, and then the power is transmitted to the charging device through a wireless way. Therefore, although the power bank itself can receive power wirelessly, it cannot transmit power wirelessly to other devices. 3. At present, the development of science and technology has not yet realized the true sense of wireless charging, but researchers are constantly working to develop technology that can realize wireless charging.
Some research directions include the use of electromagnetic resonance, magnetic resonance coupling and other principles to achieve wireless charging, which will bring greater convenience and comfort to people's lives.
can not
1, may be the charging bank data cable or power adapter damage resulting in failure to charge, replace the data cable or power adapter and charge again;
< br >
2. The charging interface or power switch of the charging bank may be faulty, and the parts need to be repaired and replaced;
< br >
3, may be the charging treasure battery aging, need to repair and replace the battery (if the charging treasure has been insured, it is recommended to directly replace the new charging treasure)
I'm sorry to hear your question. Wireless power banks are designed to charge other devices wirelessly, rather than being able to charge themselves wirelessly. It typically needs to be wired to a power source to charge, and can then transfer power wirelessly to other devices. This design can provide a more convenient way to charge, but the charging bank itself does not support wireless charging.
able
It may be because the charging head is not good, or the output current is too small, you can use the computer to charge, or change the 2A adapter to charge the charging bank.

3. The power supply of the charging treasure is excessive, resulting in no charging.

4. Check the interface, circuit board, and battery core of the charging treasure to see where the fault is.
The sensor is broken, I suggest we have it repaired,
