Today i got electronic device described as “not working”.
Device got attached to not original PSU made in China (PSP-2000) 2A 5V AC Adaptor.
I do quick voltage measurement and everything looks well. I check plug, same size as original so why it’s not working?
After quick observation i notice that device light glow very very very little, that’s give me a reason to suspect failed PSU.
PSU was very lightweight! Even switching PSU can’t be so lightweight at 2A.
When i cut off plug i notice very thin cables… they won’t carry 2A without major loss.
I break case and got into PSU… that’s what i found…
2A… ha ha ha at SHORT it’s product less than 600mA…
After using other brand PSU device start working well and i got pictures for first entry.
I often but china electronics, but remember “You got what You pay for” .
