Another thread prompted this question. I obtained a power inverter so I could run my new laptop in the car while driving...no, not for me to get on line while driving....for the kids, to play DVD movies while on a long trip. (In my 85 300TD with a new mercedes battery..nice white one!)

I dont know much about these things....will I seriously drain my battery? Will I need to run the car for, say, another hour after watching a movie to top off a depleted battery?
Is this a good excuse to install a DC Voltage meter in the car to monitor battery/charging system (I've always wanted to do this...to put in another cool gadget).

Any thoughts?

Thanks,

Mark

We run ours in the car all the time. But not when the engine is off.

No, I would not be running the thing with the car off...only when on the road.
