"Placement anywhere" + "Medium power". Heavens no. One can only hope that the "electrosmog concerned" folks jump on the train and prevent widespread use of that option, at least in mass-marketed stuff like the Ikea furniture.
Wonder if / how such equipment passes the CE / EMC tests. Possibly with the wireless charger function disabled.
