We have to give a load operating at 5V, that pulls around 2A and see whether the voltage drops. If it drops, the current rating is not 2A. Since current is always dependent on the draw of the load, it is not possible the current capability of a source like this directly.

Thank you for pointing this out again. I missed the observation part bcos it was obscured by one of the advertisements which unfortunately decided to place itself right in the middle of your article. I will be more conscious of of them next time or simply get a robust ad-ablocker.

Observation: A lot of dry solder. Fuse was intact. TL431 SMD in the secondary side was burst.

This is what was written.
