Could this be used to charge the new MacBook from a portable powerbank (with a USB-A port)?

    Yes. However, the MacBook charges at up to 29W; while this cable supports up to 36W, most USB-A power supplies will only be 5W or 10W. Check the power capacity of your USB-A charger. While this will still work on, say, a 10W charger, your MacBook would then only charge at 1/3 of the possible speed, which might not even be enough to keep it running while you use it.

  • It sure can, however most power banks only deliver 2.4amps (12W) whilst the MacBook needs 29W (3.0amps). Even high end powerbank only deliver 15W (3.0amps). If you are going to charge this from a powerbank I'd suggest a high capacity one, at least over 10,000mah (which will give you 50% charge and one that has 15W fast charge (try mophie and anker).
