No seriously, I always get blank stares when I ask people, I've called them wall chargers or power bricks, my friend called them plug chargers, my fiancee calls them dongles. What do you call these around your house, like when you're asking someone if they've seen any (______)'s
Charger.
Wall block USB wall block
Most of the time, we just call it block , I’ve never heard of wall wart. Today I learned…
Adapters for upgrading your home’s firmware.

Chargie boys.
The Dingus. Wall wart. And a whole number of colorful names if I step on one with the prongs up, or roll my ankle on one in the dark!
My family calls them charging doots
Edit: or also sometimes “wall-to-usb adapters”

Isn't it a mobile charger?
I'd call them USB adapters; "chargers" is probably slightly more common though never sat right with me since they can be used to power things other than charging.
Or more in the past we would call any kind of power adapters "transformers" but don't seem to hear that much any more.
Technically they are power supplies.
A transformer can be a power supply, but on it's own it can only transform AC power between two different voltages, so it can only be an AC:AC power supply. The number of windings on one side vs the number on the other, will determine the ratio of your voltage change.
But a pure transformer AC:AC power supply is not particularly efficient. A transformer's power rating is based on the overall number of windings it has, and on the power frequency.
So if you're lowering the voltage, it's more efficient to use mosfets to chop up your voltage at a very high frequency, then run that high frequency voltage through a smaller transformer.
And with DC power supplies, they not only need to lower voltage, but also smooth it out to a single unchanging value, and this results in an even more complex circuit where you first rectify the wave so that it's all on one side, then you chop it at high frequency then transform it, then smooth it out.
So transformers are still involved, but typically they're just one part of a larger whole with these.

Plugs?
It appears the manufacturers call them power adapters
USB chargers
Now that you make me think about it I think I've been calling them different names depending on what I intended to use them for, most of the time (I'm translating) I call them phone charger but I also called the power supply or usb power supply when I wanted to power something else.
Never thought about it.

Everything you said was except for dongle. I absolutely would not accept that in my household.

If context is unclear might add a "mains" or even "C" in the middle as needed.
