True wireless charging has been approved by the FCC, and it works from up to 3 feet away.

Wireless charging has been a popular technology for years and has gained more attention and usability for mobile devices in recent times. The wireless technology most of us are accustomed to is more accurately labeled "Inductive charging", as the device is still required to be placed on a station to receive energy and store into the battery. It does, in fact, remove wires from the equation thus qualifying the technology as "wireless", but it isn't the true wireless many people think and wish for — the ability to charge without having direct contact.

The company "Energous WattUp" is seeking to change this; they have been designing a truly wireless technology for several years now, and have a demo showing the technology in action that you can check out below. Energous uses an RF transmitter send the energy through the air to devices. It does have one primary limitation: it only works up to three feet away from the target device. Regardless of the three feet range limitation, it's still an upgrade to the current wireless technologies available today. It's quite possible that we will see an extended charging distance in the future, as these technologies continue to improve and develop.

If you're interested in more information about the technology, you can visit the official Energous WattUp website here where they describe their mission and provide a detailed timeline.

What do you think? Is it worth using a 'true wireless' technology even with the three feet limitation? Let us know in the comments below!
