What "Junk" electronics you bought and it turned out to be awesome? Basically, we stumble upon random ads or just see something while browsing and it isn't really expensive so you are like.."Lets just Try it..worst case i will throw it".

Are there any electronics you bought but it turned out to be useful / awesome / helpful etc?

Usb current meter. Help find faults whether it's the charger, cable or device. I have used this many times.

I have basic one that can measure only 5v and 9v. Wishing to buy one with pd, qc and type-c to c support.

For me this used to be a hobby over a decade ago. People selling non working stuff on classifieds cheap which were mostly simple fixes.

However I wouldn't do it today because most such sources these days have too much dealers and hustlers selling scrap items at crazy prices pretending to be private sellers

One great example was a Lenovo monitor i got off olx for 1k from a graphic designer dude who was relocating (and it had a black line) and i needed a monitor badly to work because my work laptop screen broke.
Apart from the line the colours and contrast were spectacular and i ended up buying another Lenovo L series recently (these things are very underrated as there are absolutely no reviews but their design is gorgeous)
