Question about inverter
If i want to run a laptop off the 12volt in my car, can i get away with a regular inverter, or do i need one of the "pure" inverters? All info on the subject is appreciated!

also, i saw car adapters for laptops for sale (about $60). can i use that instead of dc-to-dc converter? (or are THEY the dc-to-dc converters?)
your info is appreciated!

a dc-dc converter just converts a certain dc voltage like 13.8V to some other DC voltage like 19V or whatever. it is harder to do that with DC than AC because you cannot just use a simple transformer to change voltages.

Ok, now i got it. I'll be going with that car adapter for my laptop. Thanks for your time and info!
