    i've been looking over the net for an hour coming up with many products. However, they seem to specify only a limited range of macbooks/pros and it worries me if i ever decide to buy the wrong one.

    is there any car charger adapter for the new i5/i7 macbook pros out yet?

    any adapter that says it can provide at minimum 60W will be able to provide power for a MBP (any MBP).

    It needs to provide 85W to charge the battery though.

    Just be aware, it'll likely need to be a separate power source, as the power provided by most lighter sockets in automobiles are rated at 5A, and you'll need at least 7A to provide enough DC power at 12V.

    the MBP runs at 16.5V-18.5V 4.6A max

    So basically you're looking for a DC-DC step up converter to change your 12V car DC power, to a 16.5V-18.5V power source.
