Review on Kensun Dual Power Portable Tire Inflator: Durable, Easy-to-Operate Air Compressor for Home Outlet (110V AC) & Car Cigarette Socket (12V DC) by Benjamin Chang

Yes it works and it works very well. Might be a bit slower for bigger tires, but if you need one of those, inflation speed isn't that big of a deal. If you're looking for one of these, be sure to buy one, in addition to draining your car battery. Mine is used more at home than on the go. Good product at a reasonable price. Better than a lot of what you see at car dealerships (if they even have them). I would buy again.
