Portable tire inflator

[Mustillo]

I'm working on building a winter / emergency kit and I'm trying to decide on a portable cordless inflator. Things I'm looking for:
-- fits under the rear seat in the storage area
-- 110V AC / 12V DC power (redundancy seems like a smart idea since the ZR2 has AC power)
-- can handle the stock ZR2 tires

There are tons of models out there and tons of reviews but I thought I'd ask here to hear about direct experiences with a ZR2 and a tire inflator. Thanks!
