I bought a few cheap wireless charging receiver modules. [Copy link]

 

A few days ago, I bought a few cheap wireless charging receiver modules, planning to use them to modify devices in the future.

This module is probably from stock, it looks relatively new and each one is covered with a plastic bag.

There are two output contacts on the reverse side

In order to test whether this module is normal, I found the wireless charger at the bottom of the box. When there is no device, the indicator light is red.

Put the wireless charging receiving module on and the indicator light turns blue, indicating that it can be recognized.

I measured it with a multimeter and the no-load voltage was 4.9V. If you have time, connect a load and try again.

The adhesive is very sticky and it is not easy to remove without damage. I didn't remove it because I wanted to keep it and use it. Here is a picture from the seller.

I have disassembled this thing, the coil and the small power board, and used it for my wife's iPhone 13. The charging is extremely slow, but the light pollution on the bedside table is quite bright at night.

Are you planning to get the Qinheng charger? Looking forward to it!

It wasn't originally planned, but it's something I can consider.

Your receiving module is OK, it can output DC 5v, and should be able to be directly connected to the USB port of the mobile phone

It should be used for wireless charging of a certain mobile phone. It is also good to modify it for wireless charging of other devices.

I have used 2 models, and both of them generate a lot of heat, and their efficiency needs to be improved.

Low-cost solutions are all relatively inefficient.

There should be no big problem, it is suitable for wireless charging of low-power devices

I guess they are all previous stock, it would be nice to buy a few to play with.

Can the charging case of TWS be modified?
