This review is from: MobileSpec MS100W 100-Watt DC to AC Power Inverter with USB Input and 12-Volt Port (Automotive)

I have several AC car adapters and this is the first one I got with all the three outputs, an 120V AC outlet, USB, and cigarette 12V output; one for each.

This is one of the smallest AC adapters that I ever bought. 100W seems to be very puny, but if you just use it with low powered electronics, it should be enough. Right now, an iPhone is plugged on the USB outlet, and a GPS on the cigarette lighter outlet at the same time. If you are a camper, forget about using it for your air compressors and the likes, look somewhere else then. Typically, it will power laptops, cellphones and other low powered electronics like the kids' video game portables.

I know it is a little scary to plug in directly your expensive gadgetry like the iPhone and iPods through the USB, but I did it anyway. If you want, you can plug your iPhone first on its own adapter, then plug it to the inverter's AC outlet. That way the iPhone adapter may serve as an isolating transformer.

The fan kicks in and a blue LED light will come on once you plug it in. It is not very loud (I have other adapters that are much louder) but you will hear it on top of your music if you only play at medium volume.

The length of the cord is 3 feet. I have an AC adapter that sticks like a brick on the front that is very inconvenient when I shifting my gears, the main reason why I bought this. The unit has rubberized feel.

The holes for the USB and ac both has rubber covers to keep off dust. The cigarette hole don't have any cover on it.

So far, it is still working after a month. Made in China

This product stopped working almost immediately. It has a fan that seems to hit the housing, and did not work at all.

It's lightweight and built pretty solid. I haven't had any problems with it so far, powering my laptop and phone - even after usually just throwing it on the passenger side floor and having it roll around. For the price it definitely can't be beat.

I think the other guy who left a one star review might've just had a dud.

edit: Still holding up and functioning flawlessly after 4 months. I'm actually surprised, seems most Chinese junk breaks within a few weeks if not days. For the price I got it ($10) I'm very satisfied.
