Only charging with USB PD

[DustBow]

Sometime in the last week or 2, the charging on my Pixel 2 has gotten a little weird. When not using a true PD charger, I noticed the lock screen now says "charging slowly" - I believe it used to just say "charging."
But the main issue is that the phone doesn't seem to charge at all with these connections.
I usually use the OEM charger and a PD charger in my car, but at my desk at work & couple spots in our house I'll use other chargers. They always charged the phone, just at a slower rate obviously... But now it appears any non-PD charger doesn't charge the phone at all... The lock screen & battery symbol show charging but the battery percentage doesn't increase and even decreases sometimes.
I'm wondering if an update changed something for the worse?

Anyone else experience this?

Pixel 2 XL 128
When not using the Pixel charger I use an Anker Powercore 10000 powerbank.
I've not noticed any difference when charging.

After some quick testing, I'm pretty sure I have figured it out. I was using micro-usb to usb-c adapters on the chargers in question.
I pulled out a true type A - Type C cable and tried that in a non-PD charger.
And the screen says "charging" and went up a good percentage in the last half hour or so.

So I'm thinking an update somewhere along the line has made the phone more picky about the connections & the adapters I have don't pass the test any more ... So the phone barely trickle charges with them

I've only been using my MBP's 80W charger

A microUSB connector is limited to about 900mA, because a Type A port is usually limited to that. (Some of the better made ones can handle 1,500mA.) So if your phone is using around 900mA internally, and you're charging it with a microUSB cable, the charger might be limiting the charge to 900mA - meaning a net charge of 0. (That's why you'll see complaints that the phone is discharging with the charger plugged in and working - the phone is drawing more from the battery than it can from the charger.)

Having it charge when using an S-C cable kind of proves it.
@TripleOne - the P2 and the P2XL are limited to drawing 10 Watts, no matter how much current the charger can supply. (Unfortunately.)

Yep! I'm just happy with being able to charge my Pixel with my Mac's charger
