I'm trying to avoid the permanent solution of hooking up a massive inverter straight to my battery. I'm not only doing this cause of the power drain, but also to avoid the interference it created with my HAM radio.
My laptop is the sole thing I'd hook into this. My laptop specs are as follows...
Compaq Presario R3000z w/ AMD 64 2.0GHz
1 gig RAM
80gig 5400rpm Hard Drive
128 Meg Dedicated Video Card
15.4 Widescreen Bright
Internal Wireless Card
GPS Puck running via USB
Cell Phone modem via USB
Trying to figure out what I would need in terms of a cig-lighter inverter. Here are a few I've found on eBay.
I know most of those are listed at peak ratings and the actualy continuous wattage is lower. I currently have a Vector 70w Continuous and wonder if that'll be enough. I got it for $13 and change brand new, so I figured I could use it to charge cameras if need be, but if it'll support my laptop continuously, then I'd rather not get another one.
Any suggestions or comments?
EDIT: To comment on John's post below, I do have a 750 watt inverter available to me, however, I am trying to avoid having to use it. My main issue is the interference with the ham radio seeing as I have to wire both directly to the battery terminal.
I'm not sure what the drain on the battery/alternator is with the inverter running with only my lappy hooked up, but its not something I am overly concerned with.
