I tested one that claimed to be "2A", but that proved to be BS.<br /><br />There are "Fast Charging" Qi transmitters that claim to deliver 7.5, 10 and 15W when used with a suitable mains power adapter (the adapters have multiple output voltage specs, typ. 5V, 9V and 12V, which must change according to transmitter demand).<br />I want 85% efficient 10W power transfer at a distance of 6 to 12mm when used with one of the "Fast Chargers". The credit card size Qi receivers are not capable of that.howardbealehttps://www.blogger.com/profile/18399864888952321664noreply@blogger.comtag:blogger.com,1999:blog-4681676246793118177.post-11096854781749330222019-07-28T01:58:48.793-07:002019-07-28T01:58:48.793-07:00Hi,
