Car power adapter for Macbook Pro

Apple has not licensed the MagSafe technology to any other company. There may be some companies that create "make-shift" chargers by cutting the connector off of a regular charger and connecting it to an car adapter. None of these are distributed by reputable manufacturers so you take your chances in using them. Apple does produce an airline charger but that is not compatible with an auto outlet.

A number of people have posted here that they have successfully used an DC-to-AC auto inverter. These are designed to let you run 110V devices in the car. With one of those, you could use the regular charger.

Use the "Search Discussions" window (above the "welcome box" at the right) and search for "inverter." I suspect you;ll find specific references in older posts here.

I was looking for this option as well.

Pros/cons?

I'm looking at the airline adapter A1284 for MacBook Pro. It looks like it fits in the 12v outlet in cars?

is there any danger in using the auto charger in this manner either to the car or the computer?

Yes it "looks like" it. But, it doesn't work in cars. Period.

Not to the computer. It will draw a fair bit of power from your car's electrical system, so if your battery and alternator are not in good shape, it's not a good idea.

Check out the www.hypermac.com Car Charger, which plugs into the lighter outlet, has an inverter and a MagSafe cable option.
