Wireless Power Consortium extend Qi standard to add resonance charging

In a press release today the Wireless Power Consortium, custodian of the Qi wireless charging standard widely used in Nokia handsets, has announced it has added Resonance charging to their Qi protocol.

The Qi resonant extension will allow charging with higher efficiency and lower radio frequency interference than typical resonant solutions. In addition, the extension allows for multiple device charging and charging at longer distances, all while maintaining backward compatibility. 

For consumers, this means it will be possible to charge without worrying about the exact position of their devices so they can charge anywhere, safely and quickly. 
For companies, this means greater flexibility in designing products when integrating Qi in cars, furniture, chargers, and accessories.

“Qi is the leading global wireless charging standard because its 190-plus member companies thrive in the WPC’s competitive-and-collaborative environment and are constantly innovating to produce the best wireless charging experience,” said John Perzow, Vice President of Market Development for the Wireless Power Consortium. “The WPC has created a standard that ensures safety and compatibility and frees OEMs to differentiate. That’s why Qi is used in more phones, tablets, cars, and products than any other wireless charging solution.” 

The Qi spec will maintain backward compatibility with the installed base of 40+ million devices and products worldwide, including the 60 models of Qi-compatible phones, tablets, and chargers sold today.

The first examples of the extension’s capabilities will be unveiled by WPC members ConvenientPower and PowerbyProxi at the WPC booth at the International CES in Las vegas today, at the SL-2 in the South Hall 3 lobby, located on the upper level.

Nokia’s wireless wireless charging plate now on sale at Amazon

image

Nokia’s rather interesting DC-50 Portable Wireless Charging Plate is now on sale at Amazon.co.uk.

The Qi-compatible wireless charging plate, which can work plugged like any other charging plate, and which can also then be taken on the move and charge a Qi-compatible device completely wirelessly, is on sale for £64.94 ($105.80) and offers 2400 mAh of capacity, though it is likely only about 70% of this will be available when charging wirelessly.

The accessory features.

  • Size: 69 x 134 x 12 mm
  • Weight: 150g
  • Wireless charging standard: Qi
  • Charging connector: microUSB
  • Battery technology: Li-Ion
  • Battery capacity: 2400 mAh
  • LED indicators: battery level indicator and charging indicator

The £64.95 price is on the expensive side, but considering that it combines a normal charging plate with a battery, without the need for cord management on the go, letting you charge normally at home and take extra power with you if you anticipate a long day, makes the price seem somewhat reasonable.

Will any of our readers be picking up the plate for Christmas? Let us know below.

Nokia JBL Power Up Bluetooth wireless charging speakers now only $119

image

Good speakers are ridiculously expensive these days, which makes the recent discount on Nokia’s JBL Power Up Charging Bluetooth Speakers pretty good news.

The speakers, which launched at $299, is now available for less than half price at $119 from AT&T’s online store.

The speakers will not only play back music via A2DP, but pair your handset via NFC and wirelessly charge your Qi-compatible smartphone in the charging zone above, making it an amazing wireless trifecta.

The accessory can be found at AT&T here.

32 GB Qi enabled Nokia Lumia 1520 now available at Expansys USA

image

While the AT&T Nokia Lumia 1520 is pretty cheap at only $100 on contract at the minute, it is also relatively handicapped compared to the international version, which has double the storage and comes with built-in Qi storage, meaning no need for a case which would make the large device much thicker.

Expansys USA is now selling an unlocked version of the handset for the US market with the full 32 GB of storage and Qi included.

Unfortunately the trade off appears to be that the handset does not support the full range of AT&T LTE frequencies, lacking the 850 and 1700 Mhz bands, and only supporting 800/900/1800/2100/2600 Mhz.

If you are willing to make the trade off however you can find the handset at Expansys here.

AT&T Nokia Lumia 1520 will not have Qi because AT&T supports rival PMA

Batter_1520_Qi

As regular readers will know, the AT&T Nokia Lumia 1520 will not have Qi wireless charging built in, despite the international version sporting the technology.

Surprisingly a reader was able to get a reasoned and coherent response from AT&T for this specification change.

Don Mooers, Director, Device Product Marketing at AT&T responded to a question about the change, and confirmed it was due to AT&T being a member of the Power Matters Alliance, which is a rival wireless charging standard also supported by companies such as Starbucks and Duracell. Starbucks has in fact started rolling out charging pads in their restaurants in USA with PMA support.

Don notes:

In an effort to move toward making this a reality for consumers worldwide, we’ve placed our support for the public ecosystem roll out led by Power Matters Alliance (PMA). The PMA continues to expand membership and is building a strong ecosystem for wireless charging. The PMA solution is already installed at leading coffee shops, airports, stadiums, restaurants, gyms and more, which enables customers to wirelessly charge their phone while on the go.

Of course in reality while the PMA has many members, they have precious few products released, while Qi has quite a bit of momentum from phone OEMs and accessory makers.

The good news is that a wireless charging shell with PMA support is planned, for delivery in 2014. Presumably such shells can be made for most of the other Lumia handsets with wireless charging support, with the Nokia Lumia 920 being the only one with the technology built-in.

Great news! Global variant of Nokia Lumia 1520 to have built-in wireless charging

Untitled120

NokiaPowerUser managed to dig up some more FCC dirt on the upcoming Nokia flagships, and not only discovered the exact size of the handset, but also that one version will have Qi built-in, while another will not.

From the above diagram the handset is 81 x 152 mm, which is about the same as we estimated earlier. More interesting however is the news about the Qi charger.

In the FCC report the tester writes:

Difference between RM-938 and RM-940 is that DTM feature and WCDM1700/2100 (Band 4) will be disabled from RM-940, and RM-940 will GPRS support multi-slot class 10. In the testing reported here multi-slot class 12 has been available as worst case in all the samples. Additionally, difference between RM-940 and RM-938 is that RM-940 has only Wireless Charging interface pins in the backcover, while RM-938 has built-in Wireless Charging (WPC/Qi) loop. This HW difference was tested according to FCC KDB 648474 D03 Wireless Chargers Battery Cover V01R02

The version with the built-in Qi charging loop is expected to be the Global version, which is good news for those tired of the very finicky wireless charging case.

See the FCC documentation here.

Large capacity portable Mugen battery features Qi wireless charging

One of the main reasons we like wireless charging is because it means we don’t have to bother with cables, and now Mungen has produced a portable battery with Qi integrated, which means even when we charge on the go we do not have to plug in.

The $69.95 Mugenizer N11 has an amazing 4800 mAh capacity and weighs 230 g while only being 14 mm thick.

The device supports charging via both USB port and Qi wireless connection and therefore supports a wide variety of smartphones.

The pack is only available in white and can be ordered at Mugen Power here.

Qualcomm and Verizon Wireless joins Qi standard’s board

Good news for those Windows Phone users who have either wireless charging built in or invested in the charging cases and pads.

The Wireless Power Consortium, who controls the standard, has welcomed Verizon Wireless, already a major booster of the technology, and Qualcomm, who is part of rival Alliance for Wireless Power.

The Qi standard is already well established in the market, but is threatened by A4WP, who has strong backing by companies such as AT&T, Samsung and Starbucks. Qualcomm joining the WPC board opens up the hope of some unification or truce between the two standards.

Over 170 companies now back Qi, and Qi is used to charge devices in more places than any other wireless charging solution.

Qi was also recently selected as the in-car wireless charging standard by a standards association representing Audi, BMW, Daimler, Porsche, and Volkswagen.  In addition, Mercedes-Benz has announced it will be introducing Qi-compatibility in its cars starting in 2014. Mercedes joins the Jeep Cherokee, Toyota Avalon, Toyota Prius, and SsangYong Chairman, which all currently feature Qi.

Hopefully the Qi standard has gained enough critical mass to win the battle for adoption decisively, which should allow Qi-enabled phone owners to find even more charging locations in more places.

Coup for Qi as Consumer Electronics for Automotive recommends it as a worldwide automotive charging standard

Your most expensive charging accessory yet

The Qi Wireless charging standard, as found in many Nokia Lumia handsets, is somewhat beleaguered, as Google elected to create their own standard, and Starbucks endorsed rival Power Matters Alliance.

It seems however that the Wireless Power Consortium, the foundation behind the Qi Standard, will have one hold-out. After evaluating competing standards by Alliance for Wireless Power (A4WP®), the Power Matters Alliance (PMA®), and the Wireless Power Consortium (WPC®) with its Qi® standard, the Consumer Electronics for Automotive association (CE4A) has decided to endorse the Qi Standard.

CE4A is a working group of automobile manufacturers founded in 2006 for the purpose of advancing the standardization of mobile device interfaces. German carmakers like Audi, BMW, Daimler, Porsche and Volkswagen contribute to CE4A, which operates under the umbrella of the German Association of the Automotive Industry (VDA).

Daimler is a founder member of CE4A and directs one of the eight CE4A expert groups. The Daimler company has already agreed to start installing Qi wireless chargers in their 2014 Mercedes models, likely in the arm rest or glove box.

Qi is a standard from the Wireless Power Consortium (WPC) and currently represents more than 150 companies. Hopefully we will see many more car companies joining the consortium and making it easy to keep our phones topped up without using a proprietary connector.
