Beginners • Powering from mains

I got this little 5V transformer (https://www.ebay.co.uk/itm/156163013332) intending to run a Pi Zero and 28BYJ-48 stepper motor from a ULN2003 board. (A UK plug and USB are enormous.)
It's supposed to be good for 10W at 5V. It outputs bang on 5V.

But then I started hearing stuff about things called voltate regulators and smoothing capacitors.

Have I got it wrong?
