With Qi wireless charging, you'll soon be able to charge your device from a short distance
It's becoming more and more common to find mobile devices with wireless charging capability, either as a built-in feature or integrated into third-party cases. Progress has been somewhat hampered, however, by the fact that no universally adopted standard is available. Of the three major groups trying to corner the market, Qi -- a standard created by the Wireless Power Consortium (WPC) -- has arguably been the most successful at courting manufacturers and carriers (over 200 have signed up so far). The problem is, its abilities have been limited because it only uses a method called inductive charging; in other words, you can power up your smartphone as long as it's sitting on a charging pad. Wireless, sure, but it's still only marginally more convenient than simply plugging the handset in. Fortunately, Qi's adding some crucial functionality later this year that will allow you to charge your device from nearly two inches away.
Apple proposes iPad wireless charging with a difference: power comes from the Smart Cover
Remember when Apple's Phil Schiller mentioned he wasn't into wireless charging? Well, what he specifically said was that he didn't dig "having to create another [charging] device you have to plug into the wall." In other words, Apple is probably looking for a simpler way to make the idea work -- and that's exactly what we're looking at in the patent drawings above, which are currently being weighed up by the USPTO after having been submitted back in 2011. They show an iPad's Smart Cover tricked out with an "inductive power transmitter" arranged to "wirelessly pass power" to a receiver housed within the tablet itself. The application mainly focuses on the use of magnetic attachments to trigger charging when the cover is closed, but it looks like the ultimate goal might be to use the cover as an additional battery that can keep an iPad charged up while it's on the move. That certainly sounds practical enough -- and it'd do away with the need for an additional charging accessory, which ought to keep Schiller happy for a while.
LaunchPort releasing AP.3 sleeve for juicing your new iPad the inductive way
LaunchPort is finally releasing a sleeve for the new iPad, which makes it compatible with the company's inductive charging gear. It goes on sale in September for a hefty $149, and of course, you'll also need at least one $199 tabletop or wall mount to connect it to. The sleeve also works with the iPad 2, and if you're thinking about getting one, be quick -- it's only a matter of time before resonance charging renders inductive juicing a little passé.
Japanese group transmits electricity through 4-inch concrete block, could power cars on roads
The decision to invest in an electric vehicle would be much easier to justify if the car in question offered unlimited range. That appears to be the concept behind a Toyohashi University research group's wireless power prototype, which can successfully transmit electricity through a 10 centimeter-thick concrete block. During a demonstration in Yokohama, Japan, the team sent between 50 and 60 watts of power through a pair of concrete blocks to two tires, which then juiced up a light bulb (you can see the rig just above). The project is called EVER (Electric Vehicle on Electrified Roadway), and could someday be used to keep cars moving along a highway without any need to pull over for a recharge, thanks to a constant stream of electricity coming from below the road. There are some serious obstacles to overcome before EVER can get some wheels turning -- namely, a need to pump nearly 100 times the current maximum load through concrete that's twice as thick as what they've managed today, not to mention improving undisclosed efficiency levels -- but the group reportedly said that it's up to the task, making us fairly optimistic that such a solution could one day get us from A to B without petrol. Until then, you'll probably want to plan out a pit stop or two before you leave the garage.
Duracell Powermat WiCC could bring wireless charging to any smartphone, we go hands-on (video)
Powermat may have a bright future, but the company's products to date have been expensive, slightly clunky and a generally imperfect solution for bringing wireless power to mobile devices. That could all change with WiCC. The Wireless Charging Card (WiCC) is an IEEE Power Matters Alliance (PMA) standard, with the potential to integrate Duracell Powermat technology within every mobile gadget. The incredibly thin device resembles those wafer-like SmartMedia cards once used in early digital cameras, with a similar form factor, but significantly more practicality. Each WiCC includes all the PowerMat circuitry found in the company's charging cases, while also doubling as an NFC antenna. The card's success is of course contingent on cooperation from device manufacturers, who will need to add a slim connector above the battery leads, including two for power, two for NFC and two for data -- an app will monitor charging. Powermat reps say that such a connector would cost pennies to implement, however, making it a potentially easy sell.Powermat President Daniel Schreiber sees this as a major breakthrough for the smartphone industry, saying "we're going to do for wireless power what the memory card did for storage in mobile phones." We had a chance to take a look at a mock-up of the wireless card at MWC, which was resting just above the battery in a Samsung Galaxy S II. Because the phone's battery is slightly recessed, both the card and battery fit below the device's original backplate -- the WiCC lies flush with the phone's camera lens. Overall, we think there's some serious potential here, assuming device manufacturers are game to come on board. Still, don't expect to see these hitting stores anytime this year -- the company expects its other products to come to market long before the Wireless Charging Card. So for now, jump past the break to take a closer look, but don't make any plans to toss that power adapter just yet.
Sony Cyber-shot TX300V inductive charging camera and dock hands-on (video)
You may have thought that Sony's Cyber-shot TX200V was the company's most powerful point-and-shoot to date, but that's not exactly true. The company has a Japan-only version of the TX200V called the TX300V, and it's quite a compelling upgrade. The camera's most appealing addition comes in the form of a wireless charging and transfer dock -- it refuels your pocket snapper through inductive charging while also wirelessly transferring images to your computer using TransferJet. It can also draw power from your computer's USB port (no AC adapter required). Oh, and it ships in the camera box.Sadly, there aren't any plans to sell this iteration outside of Japan, and Sony's mum on pricing and availability. The camera transferred images and charged without issue during our demo (the Charge indicator lit up, at least -- we didn't stick around to watch it charge the camera). We went hands-on with the TX300V and its charging dock at CP+ in Yokohama, and you can check the camera kit out in all its glossy black glory just past the break.
Nissan Leaf to get inductive charging, lose its stem in 2013 (video)
Nissan has big plans for the still-budding Leaf. The Japanese automaker lit up its impressive Leaf-powered Smart House at the Tokyo Motor Show last week, but also demoed its wireless charging solution for a much smaller crowd at the company's Oppama factory. The device uses electromagnetic induction to transfer power between a charging pad and a receiver on the bottom of the car, with an efficiency level between 80 and 90 percent -- simply park your EV directly above the system to begin charging, and monitor progress on the ground transmission unit's control panel. The pad is expected to become available as soon as 2013, but will only be compatible with new vehicles, so you won't be able to use it with an older Leaf, unfortunately. There's a silent demo video waiting for you just past the break.
Rohm Wireless Power Transmission system hands-on (video)
Wireless power demos abound at CEATEC, and Rohm Semiconductor had their own variant on hand with a complete mix of direct-draw gadgets, along with the omnipresent charging iPhone 4 (or was it a 4S?). Like Murata's prototype, the Rohm flavor uses square electrodes instead of the coils that you'll find in traditional wireless power solutions, like Qi. But unlike that seemingly identical solution from Murata, this version supports much greater power efficiency -- something in the 92 to 93 percent range (compared to the competing pad's 70-percent efficiency rating). That means that the prototype that we're looking at here loses just seven to eight percent of power during transmission -- which is still unacceptably high, mind you, but far more tolerable. Rohm's Wireless Power Transmission system also allows you to charge or power devices by placing them anywhere on the pad, rather than directly over charging positions, and it supports much greater transmission, with one prototype outputting up to 100 watts. Since power efficiency isn't something we could verify visually, what we could see at the company's demo did appear to work quite well. Powering a gadget is as simple as dropping it on the pad. Well, resting it gently -- this is a prototype we're talking about, after all. The 50-watt pad was able to power a fan, LED light, and a couple of charging smartphones without issue. The light and fan jumped to full power as soon as they made contact. A second pad got the juices flowing to a large OLED light panel, which was plenty bright when positioned on its own pad, but glowed quite dim when joining other devices. There weren't any charging laptops on hand, like we saw over at Murata, but with power output at 50 and 100 watts, either pad could theoretically support it. Like many of the prototypes we've seen at CEATEC, there aren't any plans to actually bring the system to market, but the technology could be used in other devices. We go hands-on after the break.%Gallery-135773%
Murata Wireless Power Transmission System supports laptops, we go hands-on (video)
Do we really need another wireless charging system that's incompatible with industry standards? Murata seems to think that we do. The company's prototype uses neither conductive nor inductive transmission, instead bringing its new capacitive coupling technology to the cordless charging mix. Capacitive coupling uses square transmitter and receiver electrodes, instead of the coils used with Qi devices. It also doesn't require a physical connection like near-obsolete conductive tech, which dictates that both the charging pad and receiving device use metal connectors that must be joined to transfer current. The Murata system is far from being production-ready, with only 70 percent efficiency (30 percent of electricity is lost during transmission). The sample the company had on hand can support 16 watts of output with a maximum of 2.1 amps, making each pad capable of charging several small gadgets, or one larger device, like a laptop. Murata seemed more interested in demonstrating the concept behind capacitive coupling than actually proving that it works -- the laptop we saw "charging" was a plastic mockup, though the base did glow red when the laptop's charging pad came into contact (though it also glowed blue at times, as you can see in the image above). We did take a close look at an iPhone case, however, which appeared to be remarkably thin -- much thinner than models from Powermat, for example, though the case does extend below the dock connector. Another advantage of the square electrodes is that you don't need to place devices in a certain position on the mat in order for them to charge -- they simply need to be positioned within the general charging area. We take a closer look in the video after the break.%Gallery-135770%
Mr Fussy mods Samsung Galaxy S for inductive charging, without frazzling warranty (video)
It's not hard to find a good inductive charging smartphone these days, but German IT student Qian Qin absolutely had to have the feature on his Galaxy S Plus. What's more, it needed to be just right: no voiding of the warranty and no unsightly protrusions. So, instead of bumping his gums, he went out and purchased a Palm Pre back cover and a Touchstone dock for €30 ($40), ripped the charging circuit out of the Pre cover and stuck it into the Samsung's cover, then finally soldered a wire from the circuit to the micro-USB port (plus another wire to the microSD slot for 0V). Job done. At first, the mere mention of a webOS device gave us a twinge of sadness, but then the video after the break cheered us right up again -- you can tell within the first six seconds that this guy is a pure OCD perfectionist. You'll also find more detailed instructions at the source link, and they should work equally well for the original Galaxy S too.
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.
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.
HTC Thunderbolt inductive charging back appears in Verizon online store, sort of
While not a complete mess in terms to battery life, Verizon's HTC Thunderbolt certainly doesn't win any awards in the longetivity department. As we'd mentioned a while back, help is near with at least a simpler charging experience courtesy of a Qi-compatible inductive back for this already chubby device. To add a bit of intrigue to that story, the Verizon store link recently changed -- with the pic and $39 price tag being stripped out -- and we're seeing a part now named "ThunderBolttrade Inductive Battery Cover." Of course, our whirling, cell-addicted minds may simply be reading something where nothing exists, but we're feeling it's at least remotely possible that this inductive back may become some sort of trade-in dealio. So tell us, if this turns out to be rooted more in fact than in fiction, would a trade-in program lure you toward the dark magic of inductive charging or are you happy with that little plug you're using now?
Panasonic Chargepad wirelessly juices up mobile chargers, nothing else
We've seen plenty of wireless charging solutions that employ inductive power and other technologies to charge devices directly (heck, your next car may even have a Powermat in its console), but Panasonic's Chargepad may be the first such product to charge, well, other chargers, rather than gadgets themselves. At launch, the Chargepad will only be compatible with two models, the QE-PL101-W and QE-PL201-W, which you can use to juice up cell phones and other USB-compatible devices on the go. We'd love to see the company embedding inductive charging components in its cameras and other devices instead, but if you're an early adopter who happens to live in Japan, then you can expect to pay between $110-130 (open pricing, depending on battery capacity) for the Chargepad and a mobile charger when these hit stores on June 24. Update: As reader SegueToNowhere points out, the Chargepad has a Qi logo, meaning it should work with your favorite Qi devices.
BMW and Siemens partnering for wireless-charging EVs, cutting the cord this May
Back at CES we were dazzled by Fulton Innovation's vision of the future of wireless power, which included an inductively-charged Tesla Roadster. Now, someone's actually making it a reality. Siemens and BMW are partnering on a field trial for inductive chargers, with the device itself making its debut in May ahead of it being deployed in Berlin in June. In theory these can be installed into parking lots, taxi queues, and of course driveways, sunk right into the ground -- out of sight and mind. Neither company is saying which prototype car will be given the ability to catch the waves that these inductive chargesters will be throwing out, but we'd hazard a guess it'll be one of BMW's new i cars, which won't look nearly as futuristic as the invisible wheels above that look to have escaped from the Wonder Woman set. [Thanks, Jason]
Mobee's Magic Bar brings inductive charging to your Apple bluetooth keyboard and Magic Trackpad
The wise folks who brought us the inductive Magic Charger for the Magic Mouse are now back with a new trick up their sleeves. This time we have the Mobee Magic Bar, which can energise either an Apple Wireless Keyboard or a Magic Trackpad thanks to their identical dual AA battery compartment. To get some wireless charging action, simply install the supplied battery cylinder to either device (presumably extra cylinders will also be available for purchasing), and then slide the protruding part into the charging dock. Of course, the nature of this setup limits the number of compatible devices (unlike the flat Magic Charger), but this is still more convenient than unscrewing the lid every time you run out of juice. If this Magic Bar tickles your fancy, you can pick one up around end of June for $59.90 -- pre-order starts on May 15th.
Google HQ gets juiced with Plugless Power EV charging unit
We've seen it adorned with a giant Honeycomb and an oversized Gingerbread man, and now Google's bringing a more practical addition to its Mountain View campus -- specifically, a Plugless Power EV charging station. Its maker touts the installation as "the first public release" of the handsfree re-juicing system, and says it will eventually provided power to a fleet of low-speed EVs already in use at El Goog HQ -- the first of which has already been retrofitted to get pumped up. Who knows, maybe now we'll see something come of Google's claims to make electrical vehicles charge more efficiently. Full PR after the break.
Energizer makes single-device Inductive charger for singles looking to wirelessly mingle
Standardized inductive charging with the Qi standard is a beautiful thing, but previously Energizer's only charging pad had room for not one but two devices. If your independently-minded smartphone just still isn't ready for that kind of commitment, the pink bunny has you covered with a new single-pad Inductive charger. Like before it supports the Qi standard and offers compatibility with a variety of devices -- if you don't mind using a variety of goofy sheaths and backpacks. No word on price or availability, but really it shouldn't take long to get this to stores.
LG gets official with WCP-700 Wireless Charging Pad, fails to provide pricing
So, there's good news and bad. Naturally, we're going to start with the former. A month after we spotted this character sneaking around at Mobile World Congress, LG has finally taken the (official) wraps off of its incoming WCP-700 Wireless Charging Pad. It's a pretty familiar design -- a slim (6.29- x 3.54- x 0.39-inch) inductive charging pad with a battery of LEDs to let you know the current status of things. We're guessing this guy is designed to work initially with the Verizon-bound Revolution, but given that LG makes no mention of what phones / cases will eventually be compatible, it'll have to remain just that for now. As for the bad news? Well, aside from not knowing what exactly this unit is for (in terms of compatibility), we're also left in the dark when it comes to pricing and a ship date. But hey, at least we've got a trio of high resolution images to gawk at. Update: Fulton Innovation has just confirmed that LG is using its Qi-compliant eCoupled technology for the charging pad. %Gallery-119458%
