Thread: temporary carpc, will this power setup work?

basically, i'm using a laptop i have lying around as my temporary carpc until i build one. I'll be using an 8'' lilliput with it.

For power i'm going to use this adapter i got that plugs into my cig lighter and splits the connection so i can use both an AC source and a DC source (and also acts as a half-assed surge protector)

I plan to use the AC portion of the splitter to power the laptop, and the DC portion to power the lilliput.

Few questions i have about this are:

1. will this be safe for my cars battery? I know my headunit turns off temporarily when the ignition starts, but does the cig lighter?

2. By doing it this way, i know i'll have to manually turn on my laptop everytime i want to use the carpc.......anyway i can somehow get the laptop to turn on by itself with this setup?

here's the product:
