At home I have a charger for mobile phones and other devices that is Coated with a rubberized cover (an older Pearl universal charger).
This rubber coating can settle it, so I could push because underneath this charging pad.
The board connected to the USB power adapter and have been of a simple USB charging station an additional Qi charging station.
So ego had imagined.
The coil is really nice thin so that you can hardly recognize.
Once power is applied, a bright LED leuuchtet red.
If the mobile correctly on the spool, a green LED lights up in addition.
My phone is easily to 100% fully charged.
Then the internal Ladeelktronik turns off the phone.
The red and green LED on the charging module, however, remain at - so you can at the charging station to charge state not see.
All in all a very affordable charging function for DIY - or as in my case, the extension of an existing charger.
