I have been so far only 4 stars because we tested the device in the house on the 220, no problem it works very well (bed mattress); but we will have to use in the car, and there .... for now, I do not know what it will - In any case, the product is small and does not keep up, it's already a plus, one of the fittings is sounds spot right thing - So after waiting for at inflating the cigarette lighter ......
May 2014 - Here is tested !! I could add a star without problems; it works very well with the cigarette lighter, just a bit of noise, but it is quite fast and our "big" inflated mattress was really good; more problem to inflate the foot in the rain or shout loudly in turn for inflating !! Really very good product !!!
