At upcoming CES in January 2018, at least these two companies are going to exhibit their wireless Over-the-Air charging technologies. Both were recently FCC approved.
The transmitted power is pretty low, 5 watts for Energous WattUp and 3 watts Powercast PowerSpot. And this power is available only at short distances, but range can be up to 80 feet / 24,4 metres.
I see a future where all portable electronic devices are powered with wireless Over-the-Air charging at home and at work, and with batteries elsewhere.
Maybe in the distant and far away future portable electronic devices need only a small battery or no batteries at all, when wireless Over-the-Air charging networks cover areas like mobile networks now.
Can electric cars be powered with Over-the-Air charging?
Would you like to charge or power your devices Over-the-Air?
Is this a good future scenario or are we going to radiate ourselves ill?
