My VW Golf R has wireless charging for the phone

Wireless charging the most useless inefficient way to charge a batter. To
start with you have to make a power oscillator running at a high frequency
as 50 hz is very inefficient induction wise without a metal core as its just
a transformer after all. The higher the frequency the smaller the
transformer. Look inside a modern wall wart.
However all this conversion and conversion back to dc in the phone is a
loss of efficiency as is the coupling itself, often needing to be very
precise. If its that close to work use a bloody plug!

I have went back to the old style transformer chargers for my nokia 1100
the switched mode ones are very noisey on 80m...

Brian Gaff (Sofa) was thinking very hard :

I don't have one, but I can see the point of them. Constant wear and
tear on the charge socket of the phone, plus easy to just drop onto a
charging surface.

I now use a magnetic plug and socket. You just hold the phones charge
socket close to the plug and they pull together to make charging
contact, no wear and reasonably quick to connect.
