  • This is the wrong cable for the job, but your setup may be possible but its NOT easy.

    First you need to find out if your PowerAll Jump Starter will provide a constant 12V supply or is it designed only for few seconds of jump starting only.

    If it does provide constant 12V, you need to look for a 12V car Charger port to MagSafe / MagSafe 2 Adapter.

    To charge your MacBook, you need to connect the red jump start cable to the tip of the car charger and the black to the sides connector.

    This should do the trick.

    Apple will not recommend this, neither do I.
