I'm using the CalDigit USB-C Dock and the Mac said it is using the power adapter, but my battery is slowly draining:

I did an SMC reset and reset PRAM (NVRAM) but still won't charge.

Why isn't my Mac charging?

    Which power adapter are you using? What are the specs of the power adapter you are using?

As it turns out, the USB-C I was using is bad. I swapped the cable out for a different one, and the laptop started charging again through the dock.
