i'm getting ready to install a tablet pc based system in my car. i have both AC and DC power supplies. should i just use the DC power supply that is designed for use in a car? or is there some reason i should use the AC ps with an inverter? i also plan on using an ITPS, if that makes any difference in which i use.
DC always m8, its pointless steping up back to AC only to step down. I've bought myself one of these. not a bad price at all, and can suit loads of different laptops.
