Car charger?

You could try this. It is a car outlet to regular outlet adapter.

Okay thanks.

Anything else anyone knows about?

bumppp

I just use a plain car-plug 125W power inverter, some $30 thing at Newegg

just make sure you don't exceed the current draw on that circuit or you'll have to figure out where your car's fusebox is lol.

edit--------------
listen to IEATFISH, i forgot to mention you wanna at least meet or exceed whatever the power draw of the power brick is.

Ok thanks guys. How do i know how many volts i can use before having to reset the fusebox or whatever?
Also were going to be using the dvd player built in the car, if that makes a difference.

an inverter would be the way to go. http://www.newegg.com/Product/Produc...-123-_-Product
it has no reviews but its a top seller

Most power outlets in cars will give you enough to use an inverter that gives around 250W. So just make sure your inverter supplies enough for your power supply for your laptop. Additionally, you may want to have some spare fuses, just in case. Oh, and if you can get an inverter with some active cooling, get one, those things can get hot. Make sure to get an inverter that can supply 25% more power than you actually need, remember that a 110W power supply might actually draw more like 120-130W from an outlet, and getting an inverter that can supply more than you need will ensure that it can remain cool. Finally, make sure the inverter can supply the power you need non-stop, I've seen plenty of inverters that say stuff like "250W power inverter", and then in fine print it says "250W for 5 minutes, 200W continuous".

The brick says 100-240V, which im assuming is volts.
Anyone know how many watts that is?

it says 3.95A, i would take a pic but its an iphone, and you cant really see the words clearly.
If you want, i can tell you the model number and maker.

Nothing wrong with using an inverter but here is a car adapter for your model $44.95, link.

Edit: Added link.

Nevermind.
