OT: Laptops running on car batteries using a converter.
Ok, I'm on a camping trip and the only power source I have is my RDX with a wattage converter. I know I could charge/use my macbook while the car is on and wouldn't have a problem (except of course, till gas runs out) but my question is this, How long could the car battery run a laptop for without turning the car on?
thanks,
thanks,

I haven't measured the MacBook, but the Mac mini only consumes about 15 watts while idle and about 30 watts when playing a CD/DVD (I would assume your MacBook would be about the same). If your MacBook battery is fully charged and you are using an efficient DC-DC converter (ie laptop adapter) while playing your laptop, you should be able to run your laptop for a couple of hours on its battery before the adapter needs juice from your RDX battery for recharging. My guess would be that you could easily get 4+ hours from your combo laptop+RDX battery before being worried about the RDX battery not being able to start your car.
