Car cup holder space may be precious, but I can think of at least 3 times I would have gladly traded my 20-ounce quad Caramocha for a phone that didn't die in the middle of navigating me the hell out of downtown Portland. Whether you opt to sacrifice a console slot permanently, or just haul it out in times of need, Rally's cup holder power inverter can be, at best, a lifesaver, and at worst, a swell convenience on the road.
The unit is fuse-protected and fitted with a pair of 110-volt outlets, plus one more 12-volt outlet to increase powering flexibility. It also contains integrated iPod charging circuitry and a USB port compatible with cell phones, digital cameras, MP3 players, etc. A power on-off switch, short circuit protection, ground fault interrupter circuit, low battery alarm and auto shut down feature, overload protection, high and low voltage protection, and cooling fan look out for user and device safety during operation.
