I've seen a number of FSC car/air adapters, and I own one for my S7020. It's come in very handy on many occasions when I was with my car and laptop, but without mains power. I even managed to use it with an RV back in 2007 when I went on a tour of California, and it was very handy to just plug my laptop into a 12v socket and use it as if it were plugged into the mains.
However, I cannot find any car/air adapters for the H270. Unlike the H250 before it, the H270 requires a 120W power supply - and the biggest car/air adapter I have seen is a 100W model (S26391-F2613-L600). What I want to know is, is this device suitable for the H265/H270, or do I need to buy a third-party unit? Or do I need to wait for Fujitsu-Siemens to wake up and produce one of their own?
