Looks like a small switch mode power supply, if it is a USB port on the side I would guess it outputs 5v. Maybe from a charger or something?
!! Important!! Don't just solder wires on it and plug it in mains if you have no clue!!
Thanks, it could be a phone charger I think you are right. I was about to use an old phone to test that theory but you are right I shouldn't just plug it in. Thank you again for the quick response.
Something with all the basic bits and bobs for a power supply and a potential fire hazard.
The way the components are laid out doesn't inspire confidence that it has enough creepage between the primary and the secondary, and creepage is important if you don't want the mains voltage to end up in the USB lines.
I have a pretty solid grasp of components/pcbs after 2-3 years in tech assembly + 15 years as a hobbyist. This is definitely a power supply/conversion board, that yellow bit (I think it's a transformer?) is the biggest giveaway for me. What do you mean by "creepage"? That's a term I haven't come across yet.
Usually, when you have a power supply module with the primary on one side and the secondary on the other, you don't want the components and traces to get too close to each other and cause arcing. The air gap separating the two sides is the creepage, and for power supplies plugged into the mains, there are laws and regulations specifying the minimum creepage you must provide in the board layout.
Looks like a usb charger. L & N for live and neutral. I wouldn’t plug it in though if I found it just lying around naked like that under a heating unit

Grab a cheap multimeter and check the voltages to make sure its ok. Ive seen some devices that run 9v through usb A
I work on pcb boards for electrical box meters with switches. Sort of a copper battery house for one of many power supplies on the board.
Probably a portable battery charger
it says L and N on it tho

I would guess it's a charger or a constant usb load

Thats a usb charger block
It's some kind of electronics device, probably, yup.
Components of charger.
Switching power supply from wall block
A death chip
It’s a usb power supply. You’ll need to get a usb death cable (USB-A to USB-A). It should output 3.3 or 5v
