I found it tremendously difficult to make a purchase decision; the device manufacturers and 3rd party vendors provide very little information and everyone wants their own trademark: USB-PD, Quick Charge, PowerIQ, iSmart, VoltIQ, Turbopower... it just goes on and on.
However, I decided to hope for the best and get some well-reviewed USB-PD chargers and bought the following two chargers:
https://www.amazon.com/dp/B07PLR7T1M/ (RAVPower 61w wall charger) https://www.amazon.com/dp/B075WQQG7C/ (Necktek 45w auto charger)
They work out really well and met my requirements, with the exception that the Necktek doesn't provide the full 60 watts the Macbook can use, but I knew that was the case.
