COTS Test: Wireless Charger

COTS Test series – Wireless Power – part 1

Testing this pair of  Wireless Power Transmitter + Receiver I noticed that the output current measured was 10% of the stated value. I start to peel off the receiver and try to measure what that coil (not litzwire) receives.

Transmitter Coil: 3uH

Receiver Coil: 3uH without shield
