Powermat and Duracell forming joint venture to 'globalize wireless charging'
Duracell has been in the wireless charging business for quite a while now with its myGrid devices, but it's about to make a fairly drastic change of course. Its parent company, Proctor & Gamble, announced today with Powermat that the two companies intend to form a new joint venture in an effort to "advance and globalize wireless charging." That new venture will be called Duracell Powermat, and it's expected to begin operation early next year. As a result of the new arrangement, P&G also intends to make an equity investment in Powermat, although there's no word yet on how the deal will affect everyone's favorite pun-based superhero, Power Matt. The official press release is after the break.
Wireless Power Consortium launches Qi certification lab, cuts power cords for approved devices
The power of Qi has grown and grown since the wireless charging standard was finalized. With cord cutting becoming more desirable -- and dare we say, de rigeur, for many mobile devices -- the Wireless Power Consortium (WPC) has launched an independent lab to certify gadgets wanting on its induction charging bandwagon. TÜV Rheinland's providing the speedy certification services at its Taiwanese testing facility, so we should see the legion of Qi-powered devices continue to grow at an ever-increasing rate. Guess Power Matt made the right move joining the WPC superfriends. Qi's up, cords down, playa.
Engadget Primed: how wireless and inductive charging works
Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. The world of wireless is dragging us into the 21st century kicking and screaming. Our treatise on NFC was a great sneak peek into how our future will play out over the next five years, but we're also seeing other types of suave new tricks coming out as short-range wireless technology creeps closer to the mainstream. Wireless is the crux of convenience that will keep us calm enough to make our way through this speed-demon culture. It didn't take long for our quest to obtain simpler and faster everything to become an obsession, and it shows no signs of stopping; on the contrary, it's only speeding up exponentially at a rate even manufacturers have a hard time keeping up with. Wireless charging is making some serious headway in public mindshare. Once confined to toothbrushes and other simple household items, it's now a handy means of powering phones (HP's Touchstone, for example) and media players, and it'll soon be ready to charge up our notebooks and cameras at our command. Are we sure this is the future, or will this just be a passing fad? Why should it matter? Read on after the break to get the air-conditioned answers to those burning questions.
Flexible wireless charging sheet could eventually turn your skinny jeans into power pants (video)
If you haven't already heard, wireless charging is all the rage -- cars, cameras, and, of course, cellphones have all benefited from the burgeoning technology. Now a team of researchers at Japan's National Institute of Information and Communications Technology (NICT) are showing off a 2D power transmission system that could turn your pockets into wireless charging stations. According to its creators, "When a 2.4GHz high frequency signal is transmitted through the sheet, it becomes a wireless conductive object." Electromagnetic waves are captured in the sheet and can be concentrated in particular areas, allowing for individual activation of multiple devices, and thus increasing efficiency -- systems like Qi currently require a dedicated transmitter per device. The NICT says the power it provides is still relatively weak -- about 1W -- but it has plans to eventually bring the technology to soft fabrics. So maybe that Snuggie charging station you've been dreaming of isn't so impractical after all.
HTC Thunderbolt inductive charging back hits FCC, makes life with LTE a little easier
That inductive-charging backplate for the HTC Thunderbolt just hit the FCC, which means keeping the battery-devouring device juiced is about to get a little less inconvenient. Instead of having to plug in three times a day just to keep that LTE radio happy you'll simply be able to rest it on a charging mat... three times a day. The part made a brief appearance in the Verizon shop for $39, but the rumored April release date came and went without so much as a peep from Big Red. While we still can't say for sure when it will land, at least we know it's coming sooner rather than later -- and we've got one less reason to reconsider that pocket-busting extended battery.
Droid Charge to revive its battery via induction, completes Verizon's Qi-based trifecta
After many unexplained delays, Verizon's Droid Charge has coaxed many anxious consumers toward the edge of their seats, but we've now uncovered a tidbit that's sure to drive these folks up the wall -- an FCC document confirms this elusive Droid supports inductive charging. Just like the Thunderbolt and Revolution, the Charge uses Qi-based technology to accomplish this wizardry, which combines an optional back plate that pairs nicely with Big Red's forthcoming charging pad. As for the launch of the phone, we've stopped holding our breath. Many local Verizon resellers report the handset is in stock, however the carrier seems content in toying with the hearts of its devotees. Jump the break for a quick peek at the FCC label, which admittedly is rather bland... although it delivers the proof we all desire.
Verizon and HTC offer Thunderbolt extended battery, give your phone dumps like a truck
Though never confirmed by Verizon, it seems likely that battery life (or more accurately, the lack thereof) played a part in the series of delays preceding the Thunderbolt's launch. To combat this problem, Big Red and HTC are offering a rather unsightly extended battery pack that nearly doubles the handset's capacity from 1400mAh to 2750mAh. All that extra juice will certainly come in handy for folks leaning heavily on the phone's LTE radio. However, the device costs $50 and adds an ounce of junk in the trunk -- on a device that isn't svelte to begin with -- so why not buy another standard battery for ten bucks less instead? Then you can use the Qi-compatible back and induction charging station Verizon's releasing in April -- both are pictured after the break. It's just under $100 ($29 for the back and $69 for the pad) for those who want to cut the cord and don't mind the expanded waistline we assume comes with the privilege.
LG Revolution gets Fulton inductive charging back, HTC and Samsung handsets joining the party soon
We've just swooped our way through the Fulton Innovation stand here at MWC and found, sat next to the familiar light-up cereal box, a peculiar version of the Verizon LTE network-riding LG Revolution. Thicker than its CES-announced counterpart (by only 1.5mm, if the Fulton reps are to be believed), this Revolution features a Qi wireless charging-compatible back, which happens to go very nicely with a Verizon-branded inductive charging station. You can scope those out in the gallery below. We're told the back cover that makes this possible will be available as an accessory in the next 30 to 60 days, but the excitement for us was in hearing that Samsung also has an unannounced handset that will feature a similar add-on, which will be landing in the same timespan. While at the stand, we were also shown the back cover of an HTC Thunderbolt -- we weren't told the Thunderbolt will be making like the Revolution and getting its own chunky wireless charging adapter, but don't be surprised if it does. %Gallery-116621%
Samsung busts out SSG-3700CR active Bluetooth 3D glasses, wireless charging base station
They certainly aren't able to claim a world's first here, but our universe could still use a few extra alternatives to the flood of IR-based active 3D glasses on the market. Following up on XpanD's announcement from CES 2010, Samsung has revealed its SSG-3700CR spectacles. Hailed as "featherlight, RF-enabled 3D active glasses," these Bluetooth-equipped face accessories weigh less than a single ounce, can be operated in wired and wireless modes and are compatible with Sammy's newest LCD and plasma HDTVs. You'll also get an adjustable / removable nose pad, customized fitting options and the ability to add prescription glass, too. Oh, and since it's physically impossible to own a pair of these without also handing over as much cash as necessary for a charging base, there's the CY-SWC1000A. The outfit's calling this the first wireless charging station for its 2011 3D activate glasses, supporting up to four sets at a time and looking fairly svelte all the while. It's a crying shame that no one at Sammy is willing to talk dollars and cents, but if you've been following its other CES 2011 releases, you'll accurately assume that these two will also ship at some point in the next six months. %Gallery-112508%
Mobee Magic Charger review: wirelessly juice up your Apple Magic Mouse
Aww, look at that cute little mouse cuddling up in its nest. Wait a tick... an inductive charging mat for the Magic Mouse? You won't currently find the Magic Charger at the Apple Store (something that could change soon) but the good folks at Mobee are finally taking orders for this intriguing product on its website. To mark this occasion, the Swiss company sent us a review unit for some sweet wireless charging action. Read on for our full review after the break.%Gallery-107485%
Duracell myGrid USB Charger gives your Kindle 100 extra hours of life for $35
While Energizer's moving forward with its newfound Qi partnership, its bunny-less arch rival seems content right where it's at. Duracell's WildCharge-based myGrid charging mat, which was actually introduced over a year ago, is finally gaining a second good reason to purchase one: the myGrid USB Charger. The nugget you see above is a rechargeable Li-ion battery with a USB output, and according to Duracell, there's enough juice in there to extend the life of most smartphones by four hours and the life of most e-readers (Kindle included) by up to 100 hours. It's available today at CVS, Walmart, Target and Amazon for $34.99, and that does indeed include both mini-USB and micro-USB adapters. The full release awaits your eyes after the break.
Nagano Japan shows off yet another contactless charging system
It's been little over a month since Showa Aircraft demonstrated a contactless charging system that boasts 90% efficiency over a distance of 60 centimeters -- and now what is this? Nagano Japan Radio Co Ltd. is touting a similar system that works up to one meter, with a pretty incredible 95% efficiency at a distance of 40 centimeters. According to Tech-On, the company is currently hard at work trying to ramp the output up from "several tens" of watts to several kilowatts. As opposed to Showa's recent outing (which relies on electromagnetic induction), this system uses magnetic resonance to achieve its effect. However, as this method "drastically lowers" its efficiency when the position of the sending and receiving units are displaced, the team designed a system that automatically detects coil displacement and reorients itself accordingly. The company hopes to someday charge electronic vehicles with the thing, although we'd be happy if it merely enabled us to stow our WildCharge pads out of sight. They seriously clash with the decor here at Engadget HQ.
Showa Aircraft shows off contactless charging system, world backs on up a little
We've been hearing about true contactless charging systems for some time now (as opposed to simple wireless chargers like the Pre Touchstone), but it looks like Japan's Showa Aircraft is among the first to actually show off the real deal in action. Like some of those other proposed systems, Showa's rig uses an electromagnetic induction method, which lets it charge or power devices up to one meter apart, although it apparently works best at distances less than 60 centimeters, where it's able to reach a 90% transmission efficiency. Now, all that energy floating through the air can understandably raise a few eyebrows, but Showa assures us that it is completely safe, and they've demonstrated as much placing a frying pan between the two massive coils, which apparently did not heat up.[Via SlashGear]
Powermat hands-on
Remember the Powermat? Unlike other induction-based "wireless power" contraptions we've seen, this one came out earlier this year as total vaporware and has now resurfaced as a collaborative effort by Michigan-based HoMedics Powermat North America (HPNA). We finally got a chance to see it work in person and, much to our surprise, it seems to have delivered on its promised... at least in part. We saw three pads that touched base with six different mediators for charging various cell phones, laptops, and handheld games. The devices magnetically "lock on" to the mats and a light comes on to indicate its working. The rep told us devices charge just as fast with the mat as they would via the traditional "plug" method, but it's not like we waited around long enough to see for ourselves. No price or date, but we're a lot more excited about it knowing this thing might actually work. We're hearing some more interesting developments will be shown off later this week, from both Powermat as well as a few of the other companies here showcasing wireless power technology, which we'll be keeping an eye out for. Hit up the gallery for some sexy recharging imagery. %Gallery-40791%
WildCharger wireless charger get the hands-on treatment
While the WIldCharger wireless charging pad didn't quite make it's originally-promised release date, a helpful tipster has nonetheless managed to spend a bit of time with one, and he's thankfully provided us with some pics of the unit in action (such as it is). As you can see above, the setup consists of a charging pad and an adapter, in this case one for a Motorola RAZR. That latter component takes the place of the RAZR's battery cover (as pictured after the break), with a tiny arm that plugs into the phone's mini USB port. As an added touch, the adapter also includes a battery that ensure the phone stays stuck to the pad. According to WildCharge, both the pad and RAZR adapter are now set to ship on October 18th, with an iPod nano adapter (2G only, it seems) supposedly set to follow sometime this fall. Eventually, the company says it plans to have options for BlackBerrys, iPhones and a whole host of other gadgets, although at the rate things have been going, we wouldn't hold out for them anytime soon.
