Making your own wireless charger requires some electronic components and tools, and here is an easy way to make it:
Prepare materials: A charging coil (usually a flat coil that can be disassembled from a discarded wireless charger), a power adapter (to provide power), some wires, an electrical tape, and some other tools (such as a soldering iron, solder, etc.).
Connect the charging coil to the output of the power adapter, using a wire connection.
Connect the phone's charging port to the output of the coil, using a wire connection.
Wrap all the connections with electrical tape to prevent short circuits or electric shocks.
Place this homemade wireless charger on the wireless charging device to make sure the phone is in the correct position.
Turn on your phone's wireless charging function and wait for your phone to start charging. It should be noted that this homemade wireless charger may not be as efficient as the original wireless charger, and be careful not to put the phone in the wrong position when using, so as not to damage the phone or the charger. In addition, if you do not have sufficient electronic knowledge or experience, it is recommended to make it under the guidance of a professional.
