That by itself doesn't mean it supports pd. If you scroll up in this thread to the pics I attached, you'll see the Anker one that says USB PD. Anything non Apple will most likely clearly state PD somewhere, especially if the watts etc are mentioned.

Also the cable needs to support PD. I think the older usb-c cables from Apple don't.


Last question. If a charger shows multiple out puts with various volts and amps, is it most likely working with pd?

Well I have an HP laptop that is usb-c and the charger shows various outputs, but I can’t find the charger for sale anymore anywhere other than eBay and no mention of pd on the charger itself. It’s about a year and a half to two years old.
 
I would say that it's unlikely, but this one seems to:

These ones would charge your laptop and anything else coming up from Apple:

Well most good chargers have a chip that detects the correct voltage and will protect from current fluctuations etc. Anker calls this intelligent iq or something. Pretty much all usb chargers do that. It's not it being pd that does that. You don't have to worry about modern usb and especially USB-C chargers overcharging or anything like that. They will trickle charge when they need to. Just make sure it's a quality charger that meets spec.

This Google engineer named Benson Leung (Benson approved) used to test the quality of usb accessories, but I don't think he does it anymore.

PD just means it adheres to a spec and using that spec, it can deliver higher wattage. Instead of 15 watts, it can do 30, 45, 60 or more. I think the spec allows for up to 100.

Phones and maybe iPads will charge with non-pd chargers, at a lower rate (probably 15 w), but the devices that require pd (e.g. Nintendo Switch may not, not even slowly).

Notice how the first example says it’s pd detects and delievers the correct voltage, since the oem charger have the same voltage choices is it logical to assume it is using pd to decide what to deliver.

Many thanks for the education! Nice of you to take the time

My older mbp is still usb A. So if I bought this iPad day on day one I can’t even hook it up to my Mac without an adaptor of some kind.

This is the same concern that I have. I use wifi-sync but from time to time I'll have to plug it in, especially when I first sync the iPad Pro.

Might try this : http://a.co/d/1YQsk9Q

I have an Apple 29w USB-C power brick I bought with a USB-C to Lightning cable in order to fast charge my 10.5" iPad Pro. I figure I can still use that and swap out the USB-C to Lightning for the USB-C to USB-C cable the 11" Pro comes with if I need to fast charge. I usually try not to fast charge if I really don't need to, but it's nice to have the option.
