Wireless chargers have been around for several years, but majority require a device to be in direct contact with the station.

Energous popped 64% to 14.50 in after-hours trading on the stock market today. The company's WattUp Mid Field Transmitter has just gotten the approval of the Federal Communications Commission, making it the first "power-at-a-distance" wireless charging tech to get the green light.

Wireless charging is set to become truly wireless, albeit up to a distance of 3-feet now that the FCC has approved the WattUp Mid Field transmitter that promises to charge up gadgets without requiring them to be in physical contact with any charging board and such.

Called power-at-a-distance, the technology is different to that recently highlighted by wireless charging in the iPhone 8 and iPhone X.

Both Energous Corp. and Powercast Corp. received FCC approval this week for transmitters that convert electricity to radio waves, which are then beamed to a devices equipped with receivers.

Shah Rukh Khan is producing a Netflix show , Saif Ali Khan is starring one and R Madhavan is a part of an Amazon Prime project. The list released by Forbes India features 100 celebrities with highest earnings in the year of 2017.

Energous isn't the first startup that promised to bring a true wireless charging experience, in fact some companies are even working on a similar concept for electric vehicles.

The intended device needs a special internal or external receiver for the WattUp transmitter to work, but apparently the receiver is small enough to fit into most phones, and it reportedly also works with waterproof devices.

Such is San Jose-based startup, Energous's promise, and according to the FCC, who just certified their solution, they can indeed deliver, and safely too.

Future electronic devices can take advantage of the WattUp Mid Field transmitter. The system can now charge at a distance of 15 feet from each end of the transmitter, but the Mid Field transmitter that is now certified by the FCC can only charge at a maximum distance of three feet away. Phones, tablets, keyboards, and earbuds can be charged so long as they're connected to the right receiver.

Energous released a video demonstrating this WattUp mechanism. That means multiple devices could be left on a desk and automatically recharge, which is very convenient.
