Welcome to the PF.

Interesting -- do those wireless cell phone chargers cooperate with the phone first, to be sure it's a phone on top of them (and not a wallet with credit cards with magnetic strips, for example)? Hopefully they have that feature...

yes, the main board which located in the USB plug can identify the signal.

First, the electromagnetic signal will establish a handshake with the mobile phone signal.
The motherboard can identify the current mainstream mobile phone models
Then, according to the specific adjustment of the mobile phone to charge accordingly.

This is so cool! How did you carve out the space for the charger?

just know that you don't want to put the wireless charger to far into something like the book because it works on a really short range for safety to send the power out to a device like your phone
