I generally think of these as "transformers", but I call it a power supply. Mostly folks look at me like a Labrador trying to do calculus, and say "You mean a power brick?"

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
Usually charger brick or just brick
Charging Blocks
If the transformer is in the same housing at the plug with a separate cable (as shown): wall wart.
If the DC cable is attached, it's a charger.
If it's housed in its own case, it's a power brick.
If there's no transformer it's a power lead, unless it's rated for over 10A, then it's a power cable.
Dongles are peripherals that are housed in the same casing as the host connector. Anyone who thinks they can power a device with a dongle is a dangerous sociopath.

USB Charger
USB chargers.
"Dongles" are wire to wire USB adapters for computers. Sound "cards", Ethernet adapters, video adapters.
Charging brick.
Unless I'm describing it in a system, then it's a full bridge rectifier :)
Ladegerät
Wall wart or power brick.
"Wall Warts"
Adapter or charger. Rarely - power brick.
Wall Wart
"Charger" (lader) in general and more specific "block" (blokje)
Usb wall charger
YF-W36-2U
Though sometimes like to be more specific and say something like "hey can you grab the blue YF-W36-2U for me?"
Charge block.
Stromziegel
USB charger or adapter
Power biscuit
Charging brick. Or, if an unmarked generic brand like the ones you've shown, Fire Hazard.
Wall wart
When I was in college, we called these wall warts.
I usually call them "those, uh, usb thingies" while pantomiming plugging one into the wall
Charging brick. I don't think I've ever heard them called anything else besides a charger.
In England, we call those argy-bargy-cable-chargies.
My family calls them charging doots
Edit: or also sometimes “wall-to-usb adapters”
Power bricks or USB bricks. A dongle is an adapter, so it has some sort of thing on each side (besides a power plug lol).

Isn't it a mobile charger?
USB charger
wall warts
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.
