These have been all the rage all over the net the past few days, and I'm really impressed. I've always MEANT to make the switch to all rechargable batteries, just never really made it happen because...uh...okay, I'm lazy. But being able to recharge my pager battery by plugging it into my laptop, for example, is a geek's dream come true, let me tell you. Very nice, and very sustainable-I like this kind of idea!

Should reverse it. Should put a mini-USB port, like all cell phones. Heck, ALL products should have mini-USB ports, thereby standardizing the adapters so that I don't have 5 million adapters lying around. Could reduce the costs of selling products because you wouldn't need to include an adapter.

This product sounds great..havent been able to try it as yet. but from reading it and loking at the pictures it really seems promising. This product is so pratical it makes you think....Why only now?!?!..hope they were taking all the time to develop these properly...cause we sure dont want these to flop.

I'd think that if they produced these with mini USB ports it would require the use of an adaptor in most cases. Or am I missing something?

What's the smoke for? No fire in sight! These batteries at $23 bucks apiece will never get my USDs ($)! Doesn't mention Mah kicker, couldn't beat my 2500s. phoenix (prior comment) admits to not having rechargable batteries but he's going to bite on these?? MY camera bag/travel kit doesn't go without a full complement of fully "re-charged" AA & AAA batts. And I've never paid more than $3-4 per batt. NOTHING appeals to me about these batteries. I mean, really, why Segue when I can walk??

In the world of portable data collection and business mobility applications, one of the most vexing problems comes down to Ni-Cad or NiMH battery management schemes (will one have the power to do and complete the job at "hand"). An innovation that is simple but brilliant has just been introduced in England and, hopefully soon, to be available here in North America. Produced by Moixa Energy, USBCELL batteries will be demo'd in San Diego next week at the San Diego Demo Conference - and there are plans to distribute this product in North America by years end.

£12.99 per battery is a bit steep just for the convenience of recharging via a USB port. Most devices need at least two anyway and my camera eats four at a time. Just how many USB ports do you have available anyway? If you got to use a port duplicator to fit them all in it rather defeats the object. And what If you don't have a computer handy? It sounds like a good idea in search of a problem. I think I'll stick with my Uniross 2500mah and Universal Traveller recharger!

Why not save money buy standard rechargables ( by the way what is the capacity of the batteries? ) and a USB AA charger? I have a USB charger that charges two AA at atime, it only cost £4 ( GBP ).

Seriously folks, I was half tongue-in-cheek about them. I think it's a really good idea, but at the price point I should just go out and buy regular rechargables. However, being able to charge my AA batteries by plugging them into my laptop, which I take EVERYWHERE, is a definite plus, especially when standard battery chargers represent something extra to pack. Sheesh. Some bunchy panties around here, eh?

The downloadable data sheet shows these are a bad deal. At 1300 mAH, these batteries will last half as long as good AA rechargeables. The USB recharge cycle takes 5 hours 20 minutes to reach 90%, so for many applications, these batteries will spend more than half their working life being charged. The batteries are larger than ordinary AA batteries. The company recommends against using them in thin flashlights and other devices where an ordinary AA battery is a snug fit, warning these rechargeables may get stuck. And they're terribly expensive. Steve Fisher's comment above is right on the money: it would be cheaper to get standard AA rechargeables plus a USB charger for portable use, and that approach will give much better battery life between charges.

Oh, sigh! It sounded so good... and then I saw the price and read the comments! Why bother? I learned something, though: "...a USB charger for portable use." Hmmm, on to Google. Thanks.

These batteries are totally unsuitable for todays high drain equipment with a mere 1300 mAH capacity. They have less than half the current highest capacity AA's available at 2700 mAH. There is also a slight physical dimensional incompatibility with some equipment preventing a propper fit. The cost at around FIVE times that of a standard Ni-MH AA is absolutely outrageous with appeal only to those individuals with more money than sense. Got four free USB ports? Or are you going to buy an extra hub just for recharging? Want to leave your computer power on for 5 hours when you aren't using it just to recharge - now that's really cost effective. Don't waste your money on these batteries. It's a stupid idea and I don't expect them to be on the market for long. I live in Australia, but as far as I am concerned, this is one product they can keep in the UK.

Well they've just been released in US due to demand there, and they've announced that higher capacities are coming. The key benefit as as they don't need a charger, they are easier to recharge than conventional cells which are thrown away after one use, or often after half a dozen charges when you've lost/forgotten the charger. It sounds like a greener and more economic alternative.

I've been using these for about a year now and just keep ordering more.

The advantage: practicality. I always have 1 or 2 USB ports available no matter where I am. I travel a reasonable amount and international power plugs are just a nuisance not to mention bulky battery chargers. I've always got 2 to 4 of these batteries in my bag. But even at home, where plugs are not a problem, I always use my USBCells simply because I don't have to go looking for the adaptor. We've got USB port and hubs everywhere.

The biggest diadvantage, as already mentioned here, is the price point. They are expensive for what they are. There isn't any competition at the moment so I go direct to the source. But I can only hope that the more they sell, eventually, the lower the price will get.

What I'm really waiting for are their AAA models and their mobile battery models. The pictures of the future on their web site are enticing...
