I bought a Panosnonic portable DVD player a while back, now I am taking it on trips a lot more often. I was trying to find a car cigarette lighter adaptor to power DVD for the kids on the long trips. All I can find are the adaptors for CD players, which are not powerful enough to drive the DVD player. The most powerful adaptor I found is 1000mA 6V (made by Sony), but my DVD AC adaptor is rated 2A, 9V. I tried the Sony, it won't work. Please help, I am sure they are out there. Thank you so much. I appologize if this is not right place to post this question.
