Charge your phone from three feet away with the new WattUp from Energous

WattUp Demo
Most of us have yet to experience the joys of wireless charging — Apple’s AirPower, after all, isn’t due out for a few months yet. But thanks to a new FCC approval, we may be able to skip right past that step in the evolution of powering devices. Meet the WattUp Mid Field transmitter from San Jose-based startup Energous. It claims to be capable of converting electricity into radio frequencies, and then sending the resulting energy to devices up to three feet away. All those devices need are the appropriate receiver to accept the charge. So not only will you not have the plug in your phone in the future, you won’t even need to be all that near a charger in order to rejuice your device.

While today’s wireless charging solutions still require smartphones and tablets to be placed on a charging pad, the WattUp Mid Field transmitter needs no such proximity. In fact, no physical contact is needed whatsoever. And better still, the WattUp purports to be able to recharge several devices at the same time, with no regard for what the device is. So whether it’s your computer, your wireless headphones, or your smartwatch (or all three) that is in need of some more battery, simply place the corresponding receiver on those devices, and power on WattUp.

Energous also noted that its WattUp ecosystem “ensures interoperability between receivers and transmitters, regardless of the manufacturer.” That means if you’ve an Apple device but a Samsung transmitter, you’ll still be able to recharge remotely.

“Older wireless charging technologies have received limited adoption over the past 15 years, and are confined to contact-based charging only. The FCC certification of Energous’ power-at-a-distance wireless charging transmitter is a major market milestone,” Energous president and CEO Stephen R. Rizzone said. “Untethered, wire-free charging — such as charging a fitness band even while wearing it — is exactly what consumers have been waiting for.”

Unfortunately, you’ll still have to wait awhile longer to get your hands on one of these WattUps, as there aren’t any retail units available yet. Energous plans to show off its technology at CES 2018, which will take place January 9-12 in Las Vegas, and we’ll update you with any additional news.

For millions of people across the country, the two tech items you can pretty much count on finding in most pockets, purses, and backpacks at any give time are a phone and a pair of wireless earbuds. And their uses are vast — they bring in beautiful sound, block out annoying, distracting sound, and let us work, workout, and get from A to B while doing it.

But picking through the jungle of wireless earbuds available has gotten increasingly difficult as the breadth of brands continues to grow and tech-heavy features like active noise cancellation (ANC), transparency mode, hi-res audio capabilities, dust and water resistance ratings, and more challenge what it is we need and want in our earbuds, as well as what we can and are willing to pay for them.

This Samsung tablet can be yours for as little as $75 today
The Samsung Galaxy Tab A7 on

There are a lot of great Android tablets to pick from, and Samsung is probably one of the best companies besides Apple when it comes to tablets, so naturally, Samsung tablets tend to be both powerful and popular. That said, the higher-end Galaxy tablets from Samsung can get expensive, and if you need something simple, then the Galaxy Tab A7 Lite is a perfectly fine option. There's even a great deal on it that brings it down to just $75 from $160 with a trade-in, or, if you'd rather not do the trade-in process, you can still get it for $105, which is a respectable $55 discount.

Why you should buy the Samsung Galaxy Tab A7 Lite
The Galaxy Tab A7 lite has an 8.7-inch screen that runs a 1340 x 800 resolution, which is perfectly fine for those who want to use the tablet to stream shows and films. On the other hand, it only runs at 60Hz, so it's not going to be as smooth as the faster 120Hz screens you might see on flagship phones. It's also slim and sturdy, so you'll feel comfortable taking it around with you without having to worry about it being damaged too easily, although we'd still not be too rough with it. That said, you could probably let a kid play with it to keep them entertained while you do something, so it's a versatile option in terms of who can use it.
