Used and working Car Charger - for cigarettes lighter/12v car port to plug in MagSafe 2 compatible laptop to charge. Bought to power my 2012 MacBook Pro retina when travelling years ago. This cable will charge your laptop from car/van on the move. It cannot be used for powering the laptop whilst using it as it drains too much current and will overheat!! I just remember that from when I purchased it. But had no issues using it to charge up my Mac. Model is 85W-2 don’t remember the brand. Input dc11-15v max 10A OUTPUT 20V 4.25A
