PowerKiss joins Power Matters Alliance, plans to expand wireless charging standard in Europe

PowerKiss joins Power Matters Alliance, helps expand wireless charging standard in Europe

Now might be the time to familiarize yourself with the Power Matters Alliance (PMA). The industry's most recognizable standard, Qi, is facing serious competition from the PMA, which has garnered support from Duracell Powermat, AT&T, smartphone manufacturers such as BlackBerry and ZTE, and even Starbucks shops, which have begun rolling out its wireless charging tech in certain outlets. Beginning soon, you may be able to charge your compatible smartphone at European McDonald's restaurants, too -- the food service giant's support comes courtesy of Helsinki-based PowerKiss, which is now ditching Qi in favor of the PMA. The move is arguably the Alliance's most significant to date, and it could bring confidence to organizations currently considering their own strategies.

It's unfortunate for consumers who may have recently invested in Qi, however -- popular wireless charging spots in major European train stations, for example, will be swapping out their infrastructure to support PMA. According to PowerKiss founder Maija Itkonen, the decision was based on the standard's new technology that enables individual charging sites to monitor usage trends and control consumption, along with significant support from companies throughout the industry. We've even heard speculation that Apple may soon announce support for the PMA standard, though we remain skeptical. Regardless, this is a major blow to Qi, though it could be a significant step forward for consumers -- that $99 Powermat charging set might seem a more-reasonable acquisition now.

Nexus 4 Wireless Charger hands-on

Nexus 4 Wireless Charger handson

Palm's Touchstone dock immediately came to mind when we first saw LG's Nexus 4 Wireless Charger last fall (now available for $60 in the Play Store). Both devices are circular, with a micro-USB port in back and a slanted front surface on which to rest the phone. That's where the similarities end -- while the Touchstone is cylindrical and uses a proprietary wireless charging system, the Nexus 4 Wireless Charger is larger, spherical and Qi-compatible. Another major difference is that Palm's dock uses permanent magnets to line up and secure the handset, and LG's accessory relies primarily on the friction / suction between a rubber ring and the glass back of Google's flagship phone. Design-wise the Nexus 4 Wireless Charger looks similar to a smaller Nexus Q cut in half, down to the matching recessed square connector cutout.

In the box you'll find a 5V 1.8A AC adapter (vs. 1.2A for the one supplied with the Nexus 4) along with a micro-USB cable (longer than the one provided with the handset). The manual warns to "use only the power adapter and micro-USB cable that come with your Nexus 4 Wireless Charger", but we didn't have any trouble with other USB power sources beyond longer charging times. We tested the dock with the Nexus 4, Droid DNA, Lumia 920 and Lumia 822 (with the optional Wireless Charging Cover) -- basically, LG's accessory provides the same experience as Nokia's Wireless Charging Plate ($50), which is also Qi-compatible. The $10 difference buys you a matching design and a spare USB power adapter and micro-USB cable (Nokia's plate comes with a proprietary AC adapter). It takes about 4 hours to fully charge Google's flagship phone using wireless power -- check out the gallery above for some action shots.

Toyota 2013 Avalon Limited packs Qi wireless charging

Toyota 2013 Avalon Limited packs Qi wireless charging

Few if any of us are fans of buying 12V adapters to keep our phones powered up in the car. Those who buy the just-arriving 2013 Toyota Avalon Limited, if they choose the Technology Package, won't have to. A lid in the upgraded center stack provides Qi wireless charging to keep that Lumia 920 or Nexus 4 topped up without cluttering the console. As always, convenience carries a steep price tag: a gas-only Avalon Limited with the package costs $42,195 before the usual added fees and taxes, while a hybrid bumps that to $43,945. We wouldn't go out of our way just to skip the wires, then, but the wireless power may tip the balance for smartphone fans in the market for an entry-luxury sedan.

Alliance for Wireless Power approves its specification, edges closer to truly cable-free charging

Alliance for Wireless Power

Design by committee might not be the death knell for technology after all. Over four months after the Alliance for Wireless Power was founded in earnest, the coalition has already greenlit a specification for its partners to work from. The guideline lets device makers start building devices that charge through a magnetic resonance technology more forgiving of distance and material than Qi while simplifying the process through short-range wireless formats like Bluetooth 4.0. While the A4WP group hasn't made all the details public, it's holding meetings this week to speed up the commercialization process -- it's here that we'll learn whether the corporate bureaucracy is just as quick at getting wireless charging hardware into our hands as it is handshaking on standards.

Nokia brings wireless charging to Virgin Atlantic lounges, The Coffee Bean and Tea Leaf

Nokia brings wireless charging to Virgin Atlantic lounges, The Coffee Bean and Tea Leaf

Nokia thinks you'll like the wireless phone charging on your Lumia 920 or 820 enough to want to take it on the road, and to that end it's striking a deal to bring the cable-free experience beyond the home. Both Virgin Atlantic's lounge at Heathrow Airport and countertops at The Coffee Bean & Tea Leaf in the US will let you top up your Windows Phone without having to hunt for a power outlet. We're still waiting on details like the timing, but we're glad to know that we won't have to lug around our FatBoy Recharge Pillows just to keep living in Nokia's vision of the future.

Nokia Lumia wireless charging pad breaks cover

Nokia Lumia wireless charging pad breaks cover

That was quick: we'd heard rumors through The Verge of wireless charging coming to the repeatedly leaked Lumia 920 alongside a pseudo-PureView camera, and the mysterious @evleaks has come through with what looks to be press photos showing the wireless charging pad in action. As long as they're more than just wild imaginings, they reveal a puck-like surface that could juice up both the Lumia 920 and the less ambitious 820. We don't know much more about the charger, although it's expected to use Qi and wouldn't limit the phones and pad to coupling solely with each other. We'll know the bigger picture on September 5th; in the meantime, check after the break for a bonus picture showing both Windows Phone 8 devices with an unnamed Bluetooth headset (likely a Luna variant) that might join the charger in Nokia's accessory line.

Stanford researchers make heart implant powered by radio waves, put batteries out of a job

Stanford researchers make heart implant powered by radio waves, put batteries out of a job

Batteries used to be the only way to power implantable gadgets, but additional surgeries are needed to replace the power packs once their juice runs out -- a less-than-ideal solution for patients. Recent discoveries, however, have such medgadgets being powered by photons, hip hop and now high-frequency radio waves. Electrical engineers at Stanford built a cardiac device that uses a combination of inductive and radiative transmission of power, at about 1.7 billion cycles per second, to its coiled receiving antenna.

Previous prevailing opinion held that the high frequencies needed for wireless power delivery couldn't penetrate the human body deep enough, and the lower frequencies that would do the trick require antennas too large to work as implants. That conundrum was solved by getting the high-frequency signals to penetrate deeper using alternating waves of electric and magnetic fields. That allowed a 10x increase in power delivery -- up to 50 microwatts to a millimeter radius antenna coil -- to an implant five centimeters below the skin. That antenna also was also designed to pull power regardless of its orientation, making it ideal for applications inside always-moving human bodies. Of course, the implant's really just a proof-of-concept at this stage, but hopefully it won't be long before battery powered implants go the way of the dodo TouchPad.

Intel, IDT to make resonance charging a reality, see reference chipset coming in first half of 2013

IDT to make Intel resonance charging a reality, sees reference chipset coming in early 2013

Intel has been talking up wireless charging for years, to the point where we thought its implementation would forever remain a concept for the lab. Not so: Intel is having Integrated Device Technology (IDT) build a real-world chipset to support resonance charging in our gadgets. The lofty goal is to have a ready-made platform for charging up a mobile device or peripheral just by keeping it close to another device with a charger built-in, such as an Ultrabook; there's none of the unseemly contact plates used with inductive wireless power. Intel's commitment is still very much early and won't put a full, two-way resonance chipset into the hands of hardware makers until sometime during the first half of 2013, let alone into a shipping product. We'll take it all the same, as it just might be the first step toward embracing wireless power on a truly large scale.
