    Rohm's hydrogen fuel cells are meant to power smartphones and other mobile devices, but unlike other juicing-up solutions, the cells are only good for one charge. Rohm says disposable fuel cells can be made smaller and lighter than their multi-use counterparts, and as the only byproduct is hydrogen, the company is touting the cells' eco-friendliness. The system generates electricity by using hydrogen that's created by the reaction of a metal material and water. While the device we saw here at CEATEC is a prototype, Rohm may offer its recharging system as both a smartphone case and a USB-attachable juicepack. Each offers 5Wh and can fully charge a handset once. There's also a 200W power generator, which certainly stretches the meaning of portable but can keep a laptop, LCD TV and a peripheral or two going for three to four hours. Rohm says its fuel cells will see a commercial release some time in 2013; for now you can get a sneak peek in our hands-on gallery below. Zach Honig contributed to this report.

  • Cooler Master launches Silent Pro Hybrid Fanless Series of power supplies

    Desktop PC power supplies are tough to get excited about, no matter how many features they cram in. But Cooler Master's Silent Pro Hybrid Fanless series is actually pretty alluring. The supply isn't actually "fanless" but it does have a fanless mode that can be used to minimize machine noise, at least until the load crosses the 200W threshold. Add to that a 90-percent efficiency, fully modular cables and a control panel that lets you manually adjust the speed of your system fans and you're looking at quite the compelling product for the DIY desktop enthusiast. As you could have guessed though, all these fancy features don't come cheap. Cooler Master is offering three different models: 850W, 1050W and 1300W, which range in price from $200 to $300 -- a sizable chunk of change to drop on any component. They'll be shipping this month to the US and Asia, with Europe to follow in November. Check out the complete PR after the break.

  • Switched On: Green Plug tries to replace the worry warts (Part 1)

    Each week Ross Rubin contributes Switched On, a column about technology, multimedia, and digital entertainment. The best and most popular portable electronics products don't work for long without them, but the general consumer sentiment toward AC adapters is evident in the terms of endearment such as "bricks" and "wall warts" given to them. They're referred to with even more colorful language when they're accidentally left behind on a trip or are otherwise unavailable when needed. But if a startup GreenPlug has its way, future portable electronics products may not come with an AC adapter, much like many printers today don't come with a USB cable. With engineering talent that ran design for Apple's DC power systems for the iPod and the MagSafe connector, GreenPlug is taking on one of gadetry's holy grails – a universal connector that can work on practically any portable electronics device. GreenPlug would turn the frequently forgotten and mismatched AC adapter into an accessory ecosystem. The company envisions DC charging hubs that would be available in conference tables at the workplace and in tables and walls at coffee shops.
