I have just upgraded my alternator in my car because i want to be able to run a 13inch lcd tv and my xbox 360 in my car. I have it so the cigarette lighter has the adapter to be able to plug in two things through outlets. I was wondering if i can plug in my tv and my xbox and still maintain good battery and not have to worry about getting stuck because my car won't start?
it looks like you want to use the tv and 360 while the car isnt running, which makes it pointless upgrading your alternator, i would doubt they will draw that much anyway... the problem you will have is how big your battery is and how long you run the 2 devices for... you need to know the capacity of your battery and how much power the tv and 360 will use...
