RCA Airnergy charges gadget batteries with wi-fi signals
Thanks to all the new wireless charging systems on their way to market, the shock-horror moment of being out and about and then having your mobile’s battery die mid-way through a call may be a thing of the past. Of this new wave of chargers, the Airnergy from RCA looks to be the pick of the litter.
Airnergy works by harvesting wi-fi signals around you and converting them into electricity. Sure, we’ve seen this done before, but it’s the efficiency that is the key here; the Airnergy can convert and store enough power within 90 minutes to charge a smartphone.
The magic here is the Airnergy’s built in battery. It doesn’t need to be connected to your phone to be charged immediately. Just keeping it in range of a decent wi-fi source means power can be held onto for when you need it most.
A small and simple device, it could really challenge the Power Mat, with all its frustrating accessories, for dominance in the charger market. And at a suggested retail price of $40 (around £30) its way cheaper too.
We’ll be keeping our eye on this one to say the least.

Another great example of innovation, I am glad to find it. There are so many developers working on this segment but this is one of the best innovative idea ever. Thanks for sharing it here.

I admire the valuable information you offer in your articles. I will bookmark your blog and have my children check up here often. I am quite sure they will learn lots of new stuff here than anybody else!
“convert and store enough power within 90 minutes to charge a smartphone”
No, No it can’t. The Max transmit power of wifi in the UK is 100mw.
Most Phones have a battery around 2000mah or more. Its not even hard math.
Pure and simple bullsh**.
As Juergen says, people have been doing the math (not that its not obvious without it) and this device just doesnt work. Why is it even getting coverage?
You do realise that this one is a hoax? People have been doing the maths for the last week, and there simply is no chance at all to get enough power from any antenna to charge a battery unless you built an antenna that completely surrounds the access point (thus cutting off any wireless access) – and even then, you’d recharge faster by just unplugging the access point and using its power socket.
This device is a hoax, pure and simple.
