The Take Anywhere Electrical Power Source does away with the need for a travel adapter. It features a rechargeable 10-amp battery with more than enough juice to power a laptop not for one hour, not for two, but for three hours. It will power a cell phone for 15 hours of talk time, and even an iPod nano several times supposedly.
As for size, it’s smaller than most briefcases and sports a few AC outlets, a DC outlet, USB port, and is even outfitted with an LED for a flashlight. The internal battery can hold a charge for up to three months so you don’t have to babysit this thing to make sure you’ll have juice. The device will retail for $199.95 and would be pretty handy for those who travel a lot.
