    What's wrong with the charger that came with your MBP?

    It might work, but would be very slow. You would be better off with a 3rd party charger that delivered more power. Like the Mac Charger or the 3rd party charger.

    USB-C Power Delivery allows the charger and device to verify that the supply can provide power at voltage and current that is acceptable. I charge both my MacBook Pro 15 and Galaxy S8 with the same Anker charger occasionally. The charger only is rated for 45 W, so the charging of the Macbook Pro is slow. But in a crisis, it works. Your phone charger is likely rated at 15 W, so is going to be very slow to charge your Mac.

    Yep. This what I carry with me. https://www.amazon.com/Anker-Charge...ocphy=9032048&hvtargid=pla-405804129721&psc=1

    BTW, I noticed I got the wattage incorrect. It is only 30 W. But even at that it can charge, slowly, my 2018 15" MBP, and everything else I carry. (PD) Power Delivery's universal charging is winning me over to the usefulness of USB-C.

    Personally, I wouldn't risk using any power adapters other than from Apple or one they approved. No warranty if your new 2018 MBP goes up in smoke.
