I'm interested in getting this new Dell Vostro for college reasons, and am finding myself in a situation where I may have to be using it in the car sometimes... Laptop batteries typically dont last as long as it takes for me to study...so that's when I found out there are DC to AC inverters. At first I was like there's my solution, but a little searching online told me I have to "beware" of what I buy when it comes to this. This is not like a conversion from 3.5mm to RCA, USB A to USB mini b, where all those types of converters are the same. Each DC to AC inverter seems to have its own specs. So what should I be looking for? I've read laptops are pretty delicate and require a certain level of quality when it comes to inverters. I don't want my 400 dollar laptop to screw up. Thanks for the help.
