Hacked Powermat lets you touch-to-charge your iPhone in stop-and-go traffic
When you're cruising down the highway, you've got much better things to do than fiddling with iPhone cables -- like, you know, texting and playing Angry Birds. Thankfully, this handy little Powermat hack brings the fun of wireless charging to the comfort of your mobile office, to help free up your hands a bit -- at least until Siri learns how to steer. Video after the break and instructions in the source link -- but please, pull over to the side of the road before attempting to install.
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%
Touchstone mod blesses Samsung Epic 4G Touch with inductive charging powers
The Touchstone's future is just as unclear as any other webOS product at the moment, but it's sure getting a fair share of love from the mod community. Not only did we witness the inductive-charging unit work on a modded Samsung Galaxy S Plus, a bold and daring AndroidCentral Forums member also accomplished the feat on his three-day-old Epic 4G Touch in a process that's definitely not for the faint of heart. The modder (who goes by the name of "darrenf" on the forum) offers a full step-by-step guide on exactly how to do it, but advises that it's "a pretty delicate mod" and attempting it will likely void any warranties or return policies that were attached to the phone when purchased. It also doesn't result in the most aesthetically pleasing look since the charging coil had to be attached to the outside of the phone, but it's gotta give you some massive street cred if you pull it off, right?
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.
LaunchPort wirelessly charges iPad 2, infects users with glee (video)
Shiny, happy people staring at iPad 2s? Why, it must be the power of inductive charging, or just hyper-enthusiastic marketing. Revealed at CEDIA 2011, Dana Innovations' recently announced LaunchPort system takes the convenience of wireless charging and slaps it on your wall. Of course, there's the regular ol' option to have your Apple slab recharge from a flat top surface, but then you'll be missing out on the 360 degree pizzazz. The price of this fancy doesn't come cheap either, with both the wall- and base-mounted options costing $200 each, plus the $150 for the mandatory PowerShuttle sleeve and the $10 pre-order fee. Now, how badly do you need to show off that Jony Ive-designed tablet? Skip past the break to witness overacting at its finest.
Droid Bionic loses FCC confidentiality, gets updated with pics and user manual
When it rains, it pours, and the latest in the torrential downpour of Droid Bionic news comes straight from the FCC itself: we've got a manual. The user's guide starts by confirming the usual suspects: a 1GHz dual-core processor, 4G LTE, a 4.3" screen and a rear-facing camera capable of capturing 1080p video. The good stuff comes in on page thirteen: the Motorola XT375 supports LTE, CDMA, GSM, and UTMS, a world phone with support for over 200 countries, but unlike its WiMax cousin, the Photon, UMTS support is limited to 2100MHz only. The familial similarities are still there, however, as it seems that the Bionic uses the same connector layout (micro-USB / micro-HDMI) as the Photon, but shifted further down the edge of the phone. This means, unlike the Atrix, the Photon and Bionic just might be able to share WebTop docks and accessories. Need more than just bread and butter? An inductive charging back tagged along on the handset's federal funday, and while there's no indication that it ships with its own charging mat, we'd hazard a guess that it's compatible with existing VZW inductive chargers. Want a closer look? Check out the gallery below for the teardown of your dreams. %Gallery-130126%
Apple's inductive charging patent application finally puts its earbuds to good use
How seriously is Apple considering the possibility of adding inductive charging to its line of iOS devices? Seriously enough to submit some crudely drawn images to the USPTO, at least. The company's application for "Using an Audio Cable as an Inductive Charging Coil" surfaced today, featuring some interesting solutions to the problem of inductive charging. The first looks a bit like an iPhone scratching post. It's a big monolith you wrap an audio cord around several times, effectively turning the cable into an inductive receiving coil. The earphones in the example have a metal mesh that serve as a contact for charging the device. Another proposed system also puts the earphones to work -- though without the need for that giant charging post. Instead the headphones slip into an acoustic charger, which cause their speakers to vibrate, creating a current that charges the device. As ever, just because a patent application surfaces doesn't mean a final product will ever see the light of day -- and these methods (particularly that big charging post) do seem like a long way to go to shave off the precious millimeters that inductive charging traditionally brings. But hey, Apple's all about the svelte devices, and stranger things have certainly happened.%Gallery-129947%
Evatran's Plugless Power wireless EV charger gets smaller, conscripts Chevy Volts for testing
When it comes to technology, the old adage of "bigger is better" died a long time ago, so it's not a surprise to see "smaller is smarter" thinking apply to products and prototypes across the board. Today's (relatively) tiny wonder is Evatran's Plugless Power electric vehicle charging system: now smaller, more efficient, and primed for its first trial phase. The last time we saw Plugless Power, the system's wireless charging "station block" stretched nearly the length of a full vehicle and charged at 80 percent efficiency. Today the charge block is only slightly larger than an average hubcap, boasts a 97 percent charging efficiency, and is less picky about your car missing the wireless charger's "sweet spot." Evatran is now working on launching a test fleet of up to 12 Chevy Volts to put the system through its paces, and hopes to expand the tests to as many as 30 vehicles by January. Ready to ditch pumps and plugs forever? Start saving: a complete Plugless Power system (including vehicle retrofitting) will set you back as much as $5000 after production starts sometime in 2012. Don't be too surprised, cool stuff rarely comes cheap -- besides, that old adage has to apply to something, doesn't it?
Powermat accompanies MyTouch 4G Slide at retail launch, or so the manufacturer says
If you've already misplaced the charging cable for your MyTouch 4G Slide, then it's time to hustle back to your local T-Mobile retailer, where the new QWERTY handset is joined at its in-store launch by Powercube's inductive charging cover. Sure, your bank account just received $200 worth of hurt, but if you've got a $90 buffer on your credit card, what's an extra $30 for the shell and $60 for the Powermat, especially if it means keeping your phone alive? Sadly, both stores we called didn't have the cover, so you might want to give Magenta a buzz beforehand, although T-Mo's website is ready to take your money. No matter how you get it, you'll still need to keep the base station from getting buried under pizza boxes and laundry, but we know you're up to the task. Follow after the break for a slice of the PR.
Mobile Miscellany: week of July 11, 2011
Here's some of the other stuff that happened in the wide world of wireless for the week of July 11, 2011: Samsung launched an ad campaign for the Infuse 4G which claims its colors are "so good, they fool Mother Nature." Each ad features a different animal that mistakes the Infuse's Super AMOLED Plus screen for real nature. [via Gottabemobile] T-Mobile's MyTouch 4G is now available on Cincinnati Bell as the HTC Panache 4G for $200 with two-year agreement. [via MobileBurn] We got a sneak peek at some of Symbian Belle's UI changes, thanks to the refreshed Design Guideline docs on Nokia's developer website. [via All About Symbian] Inductive charging battery covers are now available for the HTC Thunderbolt and Incredible 2, Motorola Droid 3, and the LG Revolution. [via Droid-Life] Motorola officially announced the Fire, aka XT316. It's a portrait QWERTY handset with Gingerbread and is currently available in China. In the coming months it should work its way to Taiwan, Latin America, and Europe. The XT316 is going for $230. [via Unwired View] The popular GroupMe messaging app is now available for Windows Phone and can be downloaded for free in the Marketplace. [via MobileBurn and Gizmodo] Romanian carrier Cosmote has launched a 21.6 Mbps HSPA+ broadband service. (thx lonel) [via ZF Business Hi-Tech]
2012 iPhone rumored to feature new charging method
The Wall Street Journal has served up another batch of iPhone rumors after its (ahem) daring claim earlier that the next iPhone will be "thinner and lighter" than the iPhone 4. While the iPhone 5 (or iPhone 4S) is rumored to feature an eight-megapixel camera and will almost certainly have the same A5 processor as the iPad 2, it's otherwise likely to be broadly similar to the iPhone 4 in most respects. According to "a person briefed on Apple's product plans," Apple initially planned to launch the next iPhone during the summer as it has in the past, but the device wasn't ready and was pushed back to September. The same person claims Apple is working on a cheaper iPhone with an edge-to-edge screen. The most interesting rumor claims the 2012 iPhone will be a major redesign featuring "a new way of charging the phone." 9to5 Mac theorizes this may be similar to the Pre's Touchstone wireless charging, which uses inductive charging to top up the battery without needing to plug the phone in. Thus far rumors about the iPhone 5 have been fairly inconsistent, and as we're likely at least a year away from the sixth-generation iPhone's launch, any rumors about it shouldn't be taken too seriously at this point. Still, Apple made "cutting the cord" a hallmark feature of iOS 5 in terms of data syncing, and if the iPhone 6 does feature inductive charging, it may be the first iPhone you'll never have to plug in.
Droid 3 accessories leaked, Moto's new slider gets wireless charging back plate and more
So, you've read the rumors, scoped out the leaks, and circled multiple dates on your calendar -- just to cover all of your Droid 3 bases. You can now add a catalog of accessories to the stack of intel for this Motorola slider, including an inductive battery door (most likely harnessing the power of Qi), and a smattering of cases and screen protectors. Also thrown in the mix is a 1930mAh extended battery so you can fuel a marathon of South Park reruns and take full advantage of the last week of unlimited data from Verizon. Although knowing about the accessories is nice, we'd prefer to find out the important stuff... ya know, like how much Big Red's new Droid will cost.
Verizon stores struck by HTC Thunderbolt Wireless Charging Battery Cover
Solid as HTC's Thunderbolt may be from a software perspective, its battery life has proven to be less than striking -- unless you've been rocking it with that ultra-chunky extended battery. In comparison, its streamlined and Qi-certified battery cover was slated as another option, but there's been nary a mention of it since that accidental tease on Verizon's website in April. According to Droid Life, it's actually now available from Verizon retail locations for about $30 to complement the $70 charging base -- great for users who: a. hold disdain for cables, b. don't mind a few extra charges, or c. wear skinny jeans. There's no mention of when we'll see the hopefully convenient accessory pop up on Verizon's website, but at least it's out there somewhere for those willing to look.
Apple patent app sheds light on wireless charging dreams, NFMR love affair
Apple threw quite the wireless party by introducing PC Free and iCloud at yesterday's WWDC keynote, but it seems that the engineers in Cupertino may have even more tricks up their sleeve. Judging by a recently filed patent application, the company's hoping to add charging to its list of cord-cutting services. Specifically, the patent describes building a NFMR (near-field magnetic resolution) power supply directly into your iMac so it can charge your iPhone, iPad, or even peripherals -- such as a keyboard or mouse, when equipped with a special antenna -- without the assistance of your ol' trusty charging cords or batteries. Sporting a somewhat mature iMac that's operating sans NFMR? Pop a special USB dongle in that bad boy and presto, you're good to go. The patent points out that the range is limited to one meter, though there may be ways to install repeaters in peripherals to extend that distance further. Of course, patents won't guarantee we'll be grabbing the scissors to cut our cords anytime soon, but at least we won't have to rely on these things for the rest of eternity.
Droid Charge joins the wireless charging club, gets its own inductive battery cover
An HTC Thunderbolt wireless charging cover might still be a no-show on Verizon's site, but in the case of the Droid Charge, things are much simpler. Big Red quietly started selling a Qi-compliant inductive battery cover molded specifically for the LTE-equipped handset, allowing it to recharge when paired with any compatible charging pad. Verizon doesn't list specs, so it's unclear just how much heft that case will add to the phone's .46-inch frame. Still, if ditching your AC adapter is what you're after, you can hit the source link now and scoop one up for $29.99. [Thanks, Kalyan]
Power Matt joins the Wireless Power Consortium, gains the power of Qi
Powermat's Power Matt proclaimed his cord-cutting capabilities to the people while bearing a striking resemblance to Superman. And now, just as the Kryptonian joined the Justice League, Power Matt has teamed up with the Wireless Power Consortium to benefit all mankind -- or at least get us closer to universal contactless chargers. With the pun-loving hero embracing the power of Qi, we're just a Touchstone away from induction charging nirvana... and the next great action flick, too.
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.
