At CES, Energous presented a true wireless charging system that beams power to devices through the air, from 20 feet away, Engadget reported.

They’re calling it WattUp and it uses a proprietary solution that got demoed at CES yesterday.

The technology is ready for seamless integration into a common residential setting, providing the ability to charge a multitude of devices free of any wired connection or charging pad.

It uses the same radio bands as a Wi-Fi router, but differs from the existing crop of wireless charging systems in that it delivers meaningful, usable power at a distance.

A WattUp transmitter detects authorized receiver devices via Bluetooth Low Energy (BLE) and only sends power when needed, and requested by those devices.

Once a contact with a receiver device has been established, a WhattUp router sends out focused RF signals on the same bands as WiFi which are then absorbed and converted into DC power by a chip embedded in the device.

“These transmitters can be built into household appliances, TVs, speakers and standalone energy routers,” explains Engadget. And therein lies the only problem with the solution: receiving devices have to have the necessary chip embedded.

Energous is currently looking to license its tech to device vendors.

WattUp is controlled via an iPad app which intelligently determines which devices receive power, when and in what priority. If there are no authorized devices within range, the WattUp transmitter becomes idle and no power is wasted.

In future incarnations, the technology could automatically detect charge levels of authorized devices to beam power through the air as needed.

It’s pretty impressive when you think of it, especially given existing solution require that a device be put on a charging pad which must be connected to the power socket.

Not with the WhattUp, which lets you roam freely while your gadgets charge, a distinct advantage over charging pads. I’m keeping my fingers crossed they’ll successfully deploy this technology and that it’ll see widespread adoption soon enough.

    • I know right I told these folks wireless charging didn’t exist yet lol. Contempt that cradles and docks counted as wireless charging.

  • Newgunnerr

    That’s very nice but the router itself will probably be a few thousand dollars thus making it not so cool and it will not be widespread available anytime soon.

    • Byron C Mayes

      The first one is always pricey (remember the first iPhone?). Now that we know it can be done, others will follow and widespread adoption with prices in the range of average users will follow. This is a true game changer.

      • Wasn’t the first iPhone only $600?

      • Buzz { Light:Year; }

        Possible cancer with the waves

      • Living gives you cancer along with being born and everything else…

      • BigBot

        Better example. The first Blu-ray player was $900.00.

      • Yes that would’ve been a better example. Since the first iPhone was $600 todays iPhones are more expensive. However DVD players prices dropped significantly. They pretty much give them away now. Even with better and more features.

  • iBanks

    Finally it’s come. I remember reading something of the sort back when the 1st iPhone was to be released where an small box could be plugged into an wall and use RF to charge a device within range. Didn’t think it to be a “router” or 20 feet range. That’s awesome.

  • Nitsud

    Imagine the possibilities. Find a way to increase the range a bit and set these bad boys around a city. The city that never sleeps…or run out of battery. Hell yeah technology get on with yo badself.

  • rockdude094

    Everyone here

    • Byron C Mayes

      Hahaha! Iss funny cause iss true!

  • Chetan

    Any word on how health friendly/unfriendly will it be being on high powered RF signals?

  • 9to5Slavery

    1. Would this do harm to the device that constantly on charge of trickles of electricity compared to the wall vs qi wireless technique on the battery?

    2. Like Chetan said, is it a health hazard? Until what range? And what about when holding the device can it harm your hands or pockets or manhood?

    3. Wall direct vs router pushed electricity time to charge the same amount of battery to full ratio?

    4. What about interference?

    5. What is it not safe next to? Gas related items? Etc etc?

    6. Someone correct me, so I t uses Bluetooth to detect if it’s not 100% but if it drops to 99% it turns on? So does that mean it will turn on every 5mins?

    7. While it is charging will it have the same effect when it is charging inside the car when audio is playing it makes static noise? Will the same thing happened if connected to a sonos?

    • Diego Milano

      I’m sure they’ll say it’s as harmless as radio waves, including Bluetooth or any other WiFi connection transmitting over the air. I’m not an expert here but for some reason I am a bit reluctant about this in the long term.

      • 9to5Slavery

        2.4Ghz is dangerous for more than 30 mins if it’s contacting your body especially being 5-10feet near it. But hopefully someone catches that it goes more technical than that

      • Benjamin J Schwartz

        Wow! My mind is blown. Did you just make that whole thing up? It’s okay, we already know you did. Just curious: what do you think it means when you say 2.4Ghz radio waves “contacting your body”?

      • 9to5Slavery

        Look up 2.4Ghz home phone dangers. They hide the harmful effects.

    • adele hanks

      Common bro Get excited first

  • Reed

    How is this actually possible? Is this wireless electricity? Can you be elelctrocuted by walking in between the router and the device its charging lol?

    • 9to5Slavery

      Because spectrum is a form of energy or radio waves

  • Want!!!

  • tnx Nikola Tesla!

    • JLT

      i was looking for this comment, nobody knows!

      • Ajedi32

        Tesla didn’t use Radio waves for power transmission AFAIK. He used induction, right?

  • Dan

    sounds great, but on a health standpoint, I’d be weary of using this

    • Another company called WiTricity (http://bit ly/1tIL8Ta) is developing something similar, but not just for gadgets, also for our household appliances. They say their own tech is as harmful as the Earth’s magnetic field that’s already surrounding us, but only time will tell if it’s just another person doing whatever it takes to make money.

  • Byron C Mayes

    “And therein lies the only problem with the solution: receiving devices have to have the necessary chip embedded.”

    Could not, theoretically, someone produce an adapter with a male Lightning/microUSB connection and the necessary chip? That would make this tech backward compatible to smaller devices like phones at least. Or am I missing a key point?

    • Zachary Sloane

      This was my thoughts exactly…

    • ReanimationXP

      The size of this “chip” will determine whether this is actually feasible enough to become mainstream, and my guess is it’s huge.

  • WiseBlasian

    As others pointed out I am very worried about long term effects on the human body. I am pretty sure in 30 years we will find out that all those waves are harmful to us. I can live with low energy waves transmitting data but you would need a ton to transmit enough energy to quickly charge a portable device let alone big appliances.

  • Ryan Bartsch

    Who likes fried brain cells!?!? Come on over i got one of these things, we can enjoy it together

  • pnh

    It doesn’t stand a Snowball’s chance in a cat scanner.

  • mrgerbik

    “device can be set to ‘overdrive mode’ to fry eggs, boil water or heat your room as well!”

  • deepdvd

    Why does the article say “20 feet” when both the video and the Engadget article say 15? That would be the difference between an A+ and a C if you’re grading. Just seems odd.

  • JLT

    this was invented 100 years ago, long wait for it.

  • larry musgrove

    Nikolai Tesla did this wireless charging or should I say wireless electricity years ago.
    Nikola Tesla’s Idea of Wireless Transmission of Electrical Energy is a solution for World Energy Crisis

    The following are past newspaper articles more than 100 years old which were taken from the Tesla Collection. These are unique original articles about the wireless transmission of electrical energy printed at the time when Tesla was alive.
