Energizer USB Clip Charges DSLR Batteries
By Evan Ackerman I’ve got portable chargers for my cell phone, portable chargers for my iPod, portable chargers for my little video recorder, portable chargers for my AA batteries… The only thing I don’t have a portable charger for (besides my laptop) is my DSLR, because it takes those annoyingly square 7.4 volt battery packs…

HP Recalls 70,000 Laptop Batteries
By Chris Scott Barr If you’ve got an HP laptop that you purchased between August 2007 and March 2008, you might want to stop and pay attention for a minute. Yes, I know there’s plenty of other fun stuff to look at, but if you value your legs and the pants you’re wearing, stop for…

NorhTec Gecko Edubook Costs $200, Runs On AA Batts
By Evan Ackerman We’re big big fans of rechargeable batteries, but they’re not usually something that you think of powering devices that suck up a lot of electricity over a long period of time. Something like, oh, I don’t know, a laptop. But it looks like netbooks are just barely low power enough to achieve…

Battery Powered Battery Charger Is Probably Fake, Maybe Shouldn’t Be
By Evan Ackerman Yes, I know that this thing is most likely not real, especially since it’s from a company called “Naivetek.” The idea is you stick D batteries in one side, and it charges up AA or AAAs on the other. It sounds silly, kind of like the solar powered flashlight, but it actually…

SunCat Solar Batteries
By Andrew Liszewski Even though they’re still in the prototype stage and not terribly efficient at this point, I still think these solar powered rechargeable batteries are a brilliant idea. Designed by Knut Karlsen, the SunCats are basically a set of old NiMH rechargeable batteries wrapped in a flexible Photo Voltaic cell created by the…

[CES 2009] Fuji EnviroMAX Eco-Friendly Batteries Are Less Evil, Cost The Same
By Evan Ackerman Fuji EnviroMAX batteries are just like any other disposable batteries, except that they are actually disposable. Like, you can throw them out in the trash. Not that you should necessarily DO that, but the point is that (unlike other batteries) they don’t have any toxic elements in them. So you can feel…

Ultracapacitor Flashlight Recharges In 90 Seconds
By Evan Ackerman Ultracapacitors, or supercapacitors, are the new batteries. They recharge very, very, very quickly, the charge lasts for a long time, and you can keep on cycling them for tens of thousands of charge cycles. Kinda puts conventional rechargeable batteries to shame. Except that conventional rechargeable batteries are cheap and everywhere, but let’s…

Portable USB Power Supply
By Evan Ackerman I don’t have a USB volcano, but if I did, I bet I’d want to use it all the time, everywhere. I can do that with this USB power bar, which has a rechargeable 2200 mAh lithium battery inside plus a 5 volt USB power port to charge all your USB stuff.…

MSI Wind To Get 9-Cell, 8+ Hour Battery
By Evan Ackerman Although I’m in no way complaining about my MSI Wind‘s 6 cell battery and the legitimate 5-6 hours of productive (or whatever) on-time it provides, it’s not always enough. I guess there’s a market for this all day (8+ hour) computing thing, because Lion Battery/Mugen Power is about six weeks away from…

Futurewatch: Transparent Nanotube Steel And Super Ion Batteries
By Evan Ackerman Carbon nanotubes are pretty amazing things. They’re the strongest and stiffest material on Earth: a 1 millimeter diameter thread of them can support a weight of about 7 tons. The problem is that they’re expensive (and tricky) to produce, especially in any quantity that isn’t just broken bits of tubes. The journal…
