Support for universal micro-USB phone chargers grows with ITU approval

by Chris Ziegler posted Oct 23rd 2009 @ 5:40PM

The entire wireless industry has been congealing around micro-USB as a universal charging standard for a while now, and we've taken yet another important step toward completely ridding the world of bizarre proprietary connectors (you know what we're talking about, Samsung) with ITU ratification this week. The UN-backed International Telecommunication Union isn't just making the move to make our lives a little less hellish, though -- it's also a strategic environmental move on a couple fronts, since universal chargers mean consumers will be able to hold on to a single charger over the life of several phones and modern chargers are far more power efficient than models that are even just a couple years old. The ITU move isn't binding or compulsory, but there's enough momentum behind micro-USB at this point that it's pretty much going to happen for any phone you'd ever consider buying going forward, and many of the big players have already hopped on the bandwagon. We won't lie, we won't miss the days of buying a $40 car charger that powers, like, two LG models.

Duracell announces myGrid wireless charger, WildCharge feels a little KIRFed

by Joseph L. Flatley posted Aug 21st 2009 @ 9:51AM

No, someone didn't just Photoshop the Duracell logo on a WildCharge pad -- this actually is the newest product from the ubiquitous battery maker. Available this October, myGrid kits (including charger and one power sleeve) will be available for Nokia, Motorola, and Blackberry handsets, as well as the many flavors of Apple's iPhone and iPod touch. No price yet, but you'll know as soon as we do.

Update: Of course, this is probably the product of some sort of licensing deal -- but you'd think someone at WildCharge or Duracell would have mentioned it, right?

Kensington's iPhone / iPod charging dock throws a mini battery into the mix

by Darren Murph posted Aug 4th 2009 @ 7:17AM

At this point, you've probably assumed that there's simply no way any company can produce yet another iPhone or iPod dock that's significantly different from the legions of alternatives already out. And you're wrong. So wrong. In an effort to milk that Made for iPod / iPhone partnership for all it's worth, Kensington has just introduced its Charging Dock with Mini Battery Pack, which not only charges your dock connecting iPod or iPhone, but also energizes an external battery pack through the same USB cable. When you leave, you'll depart with a charged device as well as a charged battery pack in case you need to use 3G services for more than eight minutes. Brilliant, no? It's up for pre-order now for $69.99.

Wireless charging comes to Apple's iPhone 3GS, thanks to WildCharge

by Darren Murph posted Jun 24th 2009 @ 1:44AM

Envious of your Pre toting pals and that Touchstone charging rig? Don't sweat it -- WildCharge is coming through in the clutch to bring similar wireless charging technology to Apple's own handset. Starting today, iPhone (3G and 3GS included) and iPod touch users can order up a WildCharge Skin along with a WildCharger Pad in order to bring wire-free charging to their smartphone. Just slap the skin on, plug the pad in and toss the handset down on said pad. Just like that, you've got fresh energy flowing without having to scour the house for that little AC adapter. The pain? $34.99 for the skin, or $79.99 for the skin and pad.

Palm Pre and Touchstone get torn down gently, beautifully

by Darren Murph posted Jun 7th 2009 @ 11:27AM

As much as we love those guys and gals over at Will It Blend?, we couldn't help but cringe each time they "dissected" any given gadget. The cautious cats over at iFixit, however, are more our style. Gentle, loving, appreciative and respectful -- what else could you want in a gizmo surgeon? Per usual, they've done whatever it takes to get ahold of Palm's new Pre and Touchstone, but rather than basking in the glory of ownership, they promptly unrolled their tool belt, fired up the DSLR and proceeded to dissemble both units for your viewing pleasure. We already know that all those little innards add up to right around $170 (for the Pre, anyway), but there's nothing quite like looking at each and every chip and bit yourself. Hit up the read links below if you find your interest piqued, and don't forget to tip your hat as you exit.

CTIA follows industry trend, throws weight behind micro-USB

by Chris Ziegler posted Apr 23rd 2009 @ 8:54AM

The EU's already given micro-USB its blessing as the preferred charging standard for all things mobile, and now, CTIA has done the same in the States. The move makes perfect sense considering that the OMTP and GSM Association have both endorsed it -- and if there's one thing the entire universe can agree on, it's that proprietary connectors suck. Micro-USB is being lumped together with Energy Star compliance to form the Universal Charging Solution initiative with the goal of getting everyone on the same page by the beginning of 2012. We think that's a pessimistic goal, truth be told; tons of modern phones are already rocking micro-USB, so why can't we make this happen by, say, the beginning of 2010 instead?

Will mobile carriers charge different rates for data during peak / off-peak times?

by Darren Murph posted Mar 24th 2009 @ 11:18AM

Yes friends, your worst nightmare could indeed come true. With companies looking for every last way to nickle and dime their few remaining loyal customers, it's now being suggested that mobile operators could start charging different rates for mobile data depending on the time of day. And, let's face it, it makes total sense in a sick, sadistic way. Reportedly, carriers will soon start having a tough time keeping up with all the data-using cellphone and laptop owners, with the latter crew obviously causing the greatest strain on existing networks. A mocoNews report suggests three main ways of dealing with the uptick in demand: 1) keep building out the network and burning cash, 2) using new technology (read: LTE) with more capacity or 3) create rate plans that discourage usage during peak times. We've always heard that history repeats itself, but we'd be just fine with never hearing the words "peak time" ever again.

Palm Pre Touchstone eyes-on

by Chris Ziegler posted Jan 10th 2009 @ 10:01AM

This isn't a Palm-branded party favor, a paperweight, or a doorstop. Actually, sure, it could be any of those things if you really wanted it to be -- but Palm's Touchstone is mainly about charging your Pre and making sure it looks pretty while it's getting juiced. It's a pretty wild product (and the first accessory purchase for many a would-be Pre owner, we'd bet), so we wanted to spend a little quality time with it. We weren't allowed to do much charging on our own, but the magnets buried in the Pre certainly seemed to do their job of keeping it glued to the base in portrait and landscape orientations. Oh, and just to validate what we know you're thinking right now, yes: we overheard several Palm employees call it "the puck," so you should, too.

O2 showcases pedal-powered cellphone charger

by Darren Murph posted Jun 27th 2008 @ 8:52PM

Motorola so had this down pat last year, but we suppose O2 is just showcasing its pedal-powered charging system now that such devices are all the rage. Just days after we had a look at two unorthodox chargers from Orange, along comes rival O2 with a bicycle-related alternative. Reportedly, the eco-friendly device will be demonstrated at the O2 Wireless Festival in London's Hyde Park, but unfortunately, each of the demo bikes will be stationary. Still no word on whether O2 has a mind to take this thing commercial, but for cyclists the world over, here's to hoping it does.

Orange's recharge Pod tent to keep mobiles juiced at Glastonbury

by Darren Murph posted Jun 16th 2008 @ 9:52AM

For those fortunate enough to be planning a trip to this year's Glastonbury, you can rest assured that forgetting your mobile charger won't be the worst thing that could possibly happen. Reportedly, Orange will erect a seven-meter high recharge Pod tent in which patrons can stop by and reinvigorate their winded handset. Said tent will boast 500-watt solar panels and a 500-watt wind turbine in order to generate electricity for the lifeless phones, and Orange is hoping to juice up 100 devices per hour. If only such conveniences were everywhere...

Emergency travel charger plays nice with Palm's Multi-Connector

by Darren Murph posted Jun 9th 2008 @ 10:50PM

Oh sure, there's a plethora of portable USB chargers out there to keep most every cellphone around juiced up for one last call, but those handling a Palm handset with the polarizing Multi-Connector have long been shut out cold -- until now. Tech Center Labs has just come to the rescue with its Tiny Emergency FuelCell, which holds a single AA and enables power to be passed along to Centros and any other Palm / Treo device with the proprietary connector. Best of all, the pocket-friendly device is just $9.95 (or $10.95 with a bundled battery). Not a bad way to spend a Hamilton if you're a Palm lover.

Researchers hope to charge up gadgetry with body heat

by Darren Murph posted Jan 21st 2008 @ 3:35PM

We've heard of firms tinkering with the idea of converting excess heat directly to energy, and apparently, a team of scientists from the US Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have done just that. Oddly enough, the researchers admit that they're still unclear on how their findings actually work, but they've nevertheless discovered how to increase the conversion efficiency of converting waste heat to energy "by a factor of 100." The authors of the report suggest that clothing constructed of material embedded with thermoelectric modules could one day "recharge mobile electronic devices off the heat of one's body," and while we're certainly stoked about the idea, we're already conjuring up awful images in our minds about what this garb will actually look like.

Is Nokia pondering magnetic ports for some handsets?

by Sean Cooper posted Jan 11th 2008 @ 6:59PM

Some Nokia sets feature similar-sized headset and charging jacks and in an effort to help owners quickly tell them apart -- and prevent potential damage to the handset -- Nokia may have decided on a bit of clever gadgetry to save the day. The idea is dead-simple, one port will be positively magnetized, the other negatively, so if you try to plug in your cables to the wrong place they will repel. Safe and simple, we like it, now if they were able to extend it out to some type of MagSafe charger adapter.

Seiko Epson, Murata team up on contactless quick charger

by Darren Murph posted Sep 29th 2007 @ 4:37AM

Not even a week after startup WiPower boasted about its breakthrough in wireless power, Murata and Seiko Epson have announced plans to "jointly development a non-contact quick charging system." Reportedly, the technology "leverages electromagnetic induction," and both the charging stand and a given mobile device would be "respectively equipped with coils that generate power." As for the production, it sounds like Seiko Epson will hone in on the "transmitting side, or primary side," while Murata "will be involved in the production of the rechargeable Li-ion." The overriding goal is to recharge a handset "in about 10 to 15 minutes in a non-contact manner," which would purportedly push power transmission efficiency from current levels of 30- to 50-percent to nearly 70-percent. Oh, and we've already been assured that these "will not generate heat."

OMTP agrees on micro-USB standard for mobiles

by Darren Murph posted Sep 21st 2007 @ 1:59PM

Just over eight months after the USB Implementers Forum completed the micro-USB specification, the Open Mobile Terminal Platform (OMTP) has recommended that the protocol be accepted as a universal standard for charging and syncing mobile devices. Reportedly, the "OMTP's paper recommends that the micro-USB standard" be adopted across the mobile industry in order to "streamline the whole value chain and provide end users with a larger choice of the most popular peripherals." Still, we're not told when handset manufacturers will start offering up the new port en masse, but at least we're makin' progress, eh?
