Thread-topic: Qi chargers - any interference seen at 137kHz (or 472kHz)?

Im about to possibly procure a Belkin QI charger for her Iphone X as unfortunately son demonstrated one - my fear is it appears to be a pseudo 140Khz variable F by load and position oscillator.


Given I have little to no faith of EMC/I protection specs that adequately protect the noise floor I would love, my fear is bringing in yet another noise monster, or lurker in the KL7L house.


Any one have experiences?


regards
