It's my understanding that if you're using a lilliput with the "egg", the "egg" regulates the power to 12V. I don't think you should worry.
Can someone tell me what they think of this setup.
From cig lighter a dual adapter(http://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MEWA:IT) . One part will used to power the touchscreen other part will power the laptop. However since cig lighter is 12v and laptop requires 19v I will plug in a laptop adapter.
One main question I have is that I have read that when one starts the car sometimes the amount of voltage items recives can be more than what it should be. Does this mean I should be getting some kind of protection for the screen to stop this, since the laptop adaptor already has a surge protector.
