Best Car Power Adapter for MBP?

[Alchematron]

Any suggestions for powering a MBP in the car?

Hopefully there is a solution that will not drain the car battery too fast.

I am surprised Apple does not provide or sell one.

I have a MBP Classic.

Thank you!

wish they did.
your best bet is buy a 100watt or more power inverter that plugs into the power outlet in your vehicle. it won't drain the battery too much unless you leave it plugged in for a day or so. while the car is running it won't charge/run from the battery anyway. it gets its power from the alternator.

Try this from Kensington.
