Title: MacBook 12v Power Supply
#5
Now back on the boat. I bought the Apple airline adaptor to see if it worked.

On the plane back there were no power outlets in economy so was not able to use it.

On the boat plugged it into my 12v socket using the cigarette lighter adaptor. Nothing. Tried with the battery in and out of the MacBook. No green light, no orange light, nothing.

My old I-Book G4 ran from this socket, as does my I-Pod charger and my phone charger.

The Battery in my MacBook is marked 10.8v 55wh.
The mains power adaptor is marked 16.35v 3.65a
I recall that the I-Book G4 mains adaptor was marked around 20.2v.

Not sure what is going on here. Does the MacBook draw too much power for a 12v system to handle or is this merely a patent issue around the Magsafe plug?

Looks like I have two choices, buy a second hand I-Book or go for the Mike Guyver solution.
