Android Central at Mobile World Congress

Remember the Qi wireless charger we first showed you yesterday at Mobile World Congress? LG has today officially announced it and in the process claim that the hockey puck like charging disk is the worlds smallest wireless charger. As we found out during our hands on, it's a nice little accessory, and unlike the Nexus 4 charging orb sits flat against a surface. 

As this is a Qi certified charger, in theory any Qi compatible device should be able to take advantage of this. LG makes note of 2 of their US released smartphones -- the Nexus 4 and Spectrum 2 -- as being Qi enabled. No word on pricing or availability at this moment in time, but as this will be coming from LG direct we'd love to see a much wider availability than the currently limited Nexus 4 charger. Click on past the break for the full press release. 

 
BARCELONA, Feb. 26, 2013 ㅡ LG Electronics (LG) today introduced the world’s smallest wireless charger at Mobile World Congress (MWC) in Barcelona. At only 6.9cm in diameter, the WCP-300 is designed with portability in mind. Despite its diminutive size, the charging area is 1.7 times wider than that of LG’s previous generation wireless charger.The new model is compatible with a standard 5-pin micro-USB charger, providing the highest level of charging performance and user convenience.

The WCP-300 employs electromagnetic induction technology and is Qi certified by the Wireless Power Consortium. Electromagnetic induction produces a magnetic field that in turn generates an electric current to charge the batteries in devices placed on the charging pad. Certification ensures that the WCP-300 is compatible with all smartphones that support the Qi standard.

“Wireless charging is the holy grail of smartphone user convenience,” said Dr. Jong-seok Park, President and CEO of LG Electronics Mobile Communications Company. “With the WCP-300, LG was able to deliver both portability with top-class charging capabilities in a device no larger than a typical beverage coaster.”

In the US market, both the LG Spectrum 2 and Nexus 4 feature built-in support for wireless charging right out of the box, eliminating the need to purchase separate covers. LG believes that built-in support for upcoming smartphones will be the most critical development in making wireless charging the industry standard going forward.

LG is committed to offering consumers a better mobile user experience by introducing smartphones with more advanced wireless charging technologies in the global market.

LG officially announces new wireless charger, claims worlds smallest

Wireless charging is a nice idea, but really what's the point?
1 longer charge time.
2 greater power consumption.
3 cannot pick up the device to use it while it charges.
4 each new device will probably need a new charge mat.

USB charging can use the same AC adapter for any device and you can use your device as normal while it charges.
If plugging in a power cable bothers you buy a docking station.

wireless charge mat +£18.00 plus waisted electricity
docking station +£10.00

This is just a fad until the efficiently get to around +90% and the technology matches Tesla's wireless power solution that will provide energy anywhere in a room or house not just when the device is placed in a specific point.

1. Charge time is slightly longer than wired, but significantly quicker than USB
2. We're not really talking megawatts here..
3. True - but it saves damaging the cord / wall charger when you pick it up quickly to grab an incoming call
4. QI is a standard..
5. Saves wear and tear on the USB port which is a significant plus (if you've ever had that happen before).

It really isn't a fad, just a slow growing market limited until recently by a lack of standards and compatible hardware.

Love my Nexus 4 wireless charging orb :) Can use it in either desktop or portrait mode, which you really can't do with a traditional dock.

1. Sorry don't understand your first point. Most smartphone charge via USB. so you have an AC adapter with a USB port. with this you can plug any cable (usb to micro or usb to mini). surly wired and USB are the same. Unless you are talking about computer USB port compared to mains, and that would be system dependent on charge times.
2. even a waterfall starts with one drop of rain.....leaving your kit on stand by does not consume megawatts but 1000 people doing it does.
3. OK I can see this point then I would suggest either get a longer cable or treat you tech with respect.
4. QI is a standard that some have adopted not all and its not a standard that they have to adopt. Also as new tech in this area is developed then a manufacturer will produce a product that is not better then the competition just to comply with this standard, I don't think so.
5. this is a fair point but being in my 30's and have been using smartphones as long as they have been available, also tend to upgrade at-least yearly this has never been a problem other than with poorly manufactured handsets. then its a warranty job but i will except this as a valid point
thanks for your reply but still think its a fad. a fad that will take off no doubt but the cost vs benefit of this at this time is not worth it.

Yeah definitely not a fad. It is the future.

This is just phase one.. Remember Moores law?

In a couple years, these chargers will be cheaper, faster, and have a stronger charging pull allowing you to charge from a longer distance.

Actually there was a test done on a Nokia wireless charger that showed no power was consumed when the device was not on the mat. So therefore it uses less power than keeping a charger plugged into the wall.

you still need an AC adapter plugged in the wall so yes you are consuming the same charge as a cable charger. the mat might not loose power but its supply will. dont be conned but cleverly worded statistics. the mat does not run on either 110 or 240 so requires an adapter that will draw power. as you can see by the picture above just a USB plugged in so all your doing is taking your current charger and plugging it in to this device. same power loss when not charging

Funny that you talk about energy consumption and then actually mention Tesla's insanely impractical solution. There's a reason that no one uses it, because it's not practical.

lol yeah i hear that, but a lot of tech is based on his work. we have just move it forward. not using Tesla as an example of efficiency but an example of range, but hat of to you good point.

"LG believes that built-in support for upcoming smartphones will be the most critical development in making wireless charging the industry standard going forward."

I have to disagree here. Making the chargers themselves more affordable would be the big step in making wireless charging an industry standard. Most people are not willing to pay $60+ just for the novelty of not plugging their phone in to charge it. Get me something for $20 or less and I'll think about it...

If this was £30 or less I'd consider it, not as good as the Nexus 4 charging orb as it isn't angled, however the price of these Qi chargers and the fact that they don't add much to the usability of the device (in fact hinder it in most cases, I can't hold it in bed while reading or browsing Taptu if it's on an orb beside my bed) means I don't see the point of them for me yet. Especially when my family has enough usb chargers around the home to have one in nearly every room anyway haha

Worlds smallest? Palm Touchstone anyone?

If It's not at an angle then I don't want it. I like having it on my bed stand and I can glance at the time or who may be calling. If it's flat then whats the point, might as well just get a pad instead where I wont really have to worry much about placement.
