Wireless charging of smartphones anywhere within a 30 foot radius, without-pad ! Answered
Just read there is a 10W transmitter IC that has been developed to power a receiver IC collecting 6W of that energy...
Both are ASIC chips that can operate and power power mobile devices up to 30 feet apart.
Even though the RF energy is deemed safe.
I would plan on using a Faraday helmet and maybe lead under wear when next I visit a coffey house.
