    Does anybody know a good Magsafe 2 Car charger for the Macbook Pro Retina? I want something that will go straight from the lighter plug to the macbook, I dont want to go through getting an inverter and all that.

    You're basically going to need to go through an inverter as the rMBP uses almost double the voltage of a standard 12 volt car outlet. There are DC circuits that can up-convert voltage, but they're rare and expensive for the 90 watts the rMBP uses.

    As far as I know THIS is quite likely correct.. it is just 'simple math' and 85-90Watts at 12Volts is ~7Amps of Current Draw.. 'Invert or Fire' might be the Options!! :eek: :D

    power inverters are probably cost wise around the same cost as a car charger would be, and a lot more useful. i had one and it came with a kit to run right off my battery so not only did i use it for electronics, but i was able to tailgate with it.

    i have one that has usb outlets on it also for charging electronics etc like cell phones and crap.

    I have the DC circuit that also changes to normal wall port instead of cigarette charger.

    It charges my MBP 17' fine but extremely slow.

    If my MacBook Pro had a 17-foot screen, I would not be surprised if took a long time to charge… that must be a really big battery! :p

    sap12690, did you ever try an inverter?

    I'm looking for a way to power my 15" retina MBP (MacBookPro10,1 Mid 2012) off the 12V outlet in my car. I've not found any proof of someone doing this.

    I'm thinking about this inverter, but you can't return it if it doesn't work and I've not found it locally:
