From: PC Perspective - You can now get a Dell laptop that charges wirelessly, but it will cost you

It will set you back $1800 or more once you have purchased the requisite extra components but once set up your Latitude 7285 will charge.  The wireless charging mat puts out 18.5V which will keep you going even when working hard.  They specifically mention that it is not for use on metal desks, so keep that in mind unless you really need a jolt to wake you up.  The 2880 x 1920 12″ tablet and comes with an i7 or i5 processor, an SSD of 128GB or 256GB and your choice of 8GB or 16GB of RAM.  Keep in mind the price estimate above would be for the low end model.  Pop by The Register to see more.

“Which is where things get a bit weird, because the Latitude 7285 starts at US$1,199, but the Wireless Charging Keyboard costs $379.99 and the Charging Mat is another $199.99. That’s an extra $579.98 for the convenience of wireless charging (with a wire for the charging mat).”

From: Fossbytes - World’s First Wireless Charging Laptop Launched By Dell, Buy It For $1200

he first laptop in the world to feature the wireless charging feature is the Dell Latitude 7285 which is now available with a price tag of $1,199.99 for the starting model and $2,139 for the highest priced. The 2-in-1 hybrid device was first announced at the CES 2017 event in January earlier this year. The […]

From: BGR - Dell’s Surface competitor can actually be charged wirelessly

Wireless charging is a cool trick for smartphones, but the battery charging tech is still just finding its feet.

What if I told you that you could already use wireless charging on a 12-inch 2-in-1 laptop/tablet? Would you pay the extra $550 to enjoy this particular feature right now?

Yes, wirelessly charging a laptop is really expensive, but then again, the 2-in-1 in question isn’t cheap either.

Announced on Tuesday, Dell’s Latitude 7285 is a premium 12-inch machine that rivals Microsoft’s own Surface Pro line. The starting price is $1,199.99, which gets you 8GB of RAM and 128GB of storage. Other specs include a 2880 x 1920 anti-glare display and an Intel Core i5 Kaby Lake processor. Options featuring more RAM, storage, and Core i7 chips are also available, but the price will go up considerably.

The Wireless Charging Keyboard and Wireless Charging Mat duo sells for $549.99, which is quite expensive. The Wireless Charging Keyboard costs $379.99 by itself, while the Wireless Charging Mat is priced at $199.99, so you’d better buy them as a bundle. Yes, sadly, wirelessly charging a laptop still requires a charging mat.

The laptop does come with traditional battery charging as well if you’re not interested in wireless charging. You’ll also want to buy the cheaper-but-still-expensive Productivity Keyboard that doesn’t charge the device wirelessly — it costs $249.99.

If any of that sounds exciting, then head on over to Dell to place your order. Yes, you can buy it today, but it will only ship in 12 to 30 business days from the moment you place your order, depending on the version you end up choosing.

From: BGR - This is the kind of wireless charging we want to see in the iPhone 8

Rumors are a-swirlin‘ that the iPhone 8 is going to feature some kind of wireless charging. Although Android phones have had wireless capabilities for years, it’s a very particular kind of wireless capability: you have to physically place your phone on a special pad, and taking your device more than a couple millimeters away from the pad takes it off charge.

Sure, it’s 10% more useful than charging with cables, but I can’t imagine Apple copying a feature that debuted with the Galaxy S4. So if Apples does go the wireless charging route with the iPhone 8, you can expect it to have a little more range.

Powercast yesterday announced a new wireless charging system for small, low-power devices. Its system works for things like wearables, accessories, or low-power smart home devices, and works anywhere within about 80 feet of a base station.

It’s truly wireless charging: install a couple base stations in your house, and your headphones and smart watch will theoretically always stay charged. It sends power over a variety of wireless frequencies, and a circuit board inside your devices converts the RF energy to DC power with 75% efficiency.

The main limitation at this point seems to be the total power draw. Depending on whether or not they support quickcharge technology, smartphones generally draw somewhere between five and ten Watts while charging. Wearables sip far less power, so you can guess that Powercast’s wireless tech can supply one to two Watts at best.

In short, it’s difficult to believe that Apple has a wireless charging tech that can rival Powercast’s 75% efficiency and 80-foot range and would work for an iPhone. But something using the same concept in a smaller range could still be possible. Imagine a small base station that sits next to your PC or bedside table and charges any iPhone that comes within a couple feet. That’s the kind of step forward that could persuade Apple to finally adopt wireless charging — not to mention the kind of thing that could sell millions of new iPhones.
