I picked one up at Home Depot, and it is quite convenient to be able to charge both AA and AAA on the go with my computer. It comes with a wall socket USB charger, and software exists for it too in the form of a widget for both Mac and PC.]]>Oct 16th 2007 3:07PMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/

Broadcast power is not new, it's been around for a very long time. The reason it is not normally used is that it is extremely inefficient. In this day of "low energy footprints" I dxoubt wireless power is going to get very far.

As for the mats that will depend closely on what their final costs are. How much more expensive is a mat and the extra electronics to make it work? If it's over 50$ as I strongly suspect it will be, You're not going to see it much except in high end devices. adding an extra 50$ to a 5$ remote or a 15$ toy is not going to go over well.]]>Oct 16th 2007 12:29PMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/

These may be 1337, but a compact 2 battery usb powered charger makes much more sense, if you are determined to charge every device you have off the mains, but via your computers PSU.]]>Oct 16th 2007 11:51AMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/Oct 16th 2007 11:56AMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/Oct 16th 2007 6:54PMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/Oct 16th 2007 11:58AMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/B) What extra wear and tear, if any, will this put on my laptop?]]>Oct 16th 2007 12:05PMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/2) Barely anything

They do not have the same cap style for one thing and the packaging is different. The USBcell had 1300ma which is kind of impressive.

These are very possibly a great deal smaller. This is supported by their conspicuous lack of power information.]]>Oct 16th 2007 12:09PMhttp://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/http://www.engadget.com/2007/10/16/rechargeable-usb-battery-works-in-aa-ready-devices/

That would suggest a capacity of about 2000mah, not bad.
