Speaking as an annoyingly-frequent traveler, rechargeable battery packs are one of the single most useful products in the world. There are some times when your cell phone or GPS just can not run out of battery. Any company that can put out a truly solid advance to that line of technology wins so very many kudos from me. This year, one of the top rechargeable battery products was the Technocel PowerPak, which won a Best of Design award at the CES 2010 Engineering Awards.

CES 2010 showcases some of the most unique and well designed products made in the last year, and also features tons of demonstrations for new products coming up in the near future. The PowerPak is basically a portable battery-and-charger all in one. It works on all USB devices, and has an MSRP set at $49.99.
The battery on the PowerPak can provide up to 3 hours of extra talk time on your cell phone. It features LED indicators to show the remaining capacity of the battery, and has interchangeable tips that are billed as being compatible for 95% of all USB devices. I'm not sure how accurate that number can possibly be, but if your USB device was sold in this country it will probably fit just fine.
