Pricing for a two-cell pack in the UK is £12.99, including free delivery and VAT tax. Availability outside the UK is coming soon, according to the company. Taking advantage of the billions of USB port and getting rid chargers and cables and wasted energy makes this technology very compelling. The company has 9 volt and phone battery versions in the works. The Web site doesn't contain any information on how battery life holds up over the long term.

  • Using one battery to charge another ...

    ... seems like a waste to me.

    If you are charging your laptop anyway, then you can plug your other devices into the USB port overnight to charge it instead of carrying yet another charger but depleting the charge on your most useful device (your laptop) to insure you have a charge on a less critical device (such as a PDA or MP3 player, or anything which runs on standard AA/AAA/9-volt batteries) is just plain silly.

    • that's ONLY laptops...

      This could be charged while you're at a cyber cafe, it could be charged over night from your desktop, to be ready in the morning... you're assuming that all it's users will be using a laptop...

      there are more desktops out there than laptops... for now at least. And these seem like something you charge overnight, and use through the day... ie. when you aren't at home, with your desktop.
