Testing small power supplies

I found this 60W Electronic Load to be quite useful for testing small power adapters and supplies.

While it is possible to homebrew an adjustable electronic load we recommend getting this electronic load module or a better-but-costlier one like the UNI-T UTL8212+ electronic load.

Observations

You can stress-test power supplies using this electronic load quite easily and conveniently.

It turns out that the Orange branded 12V 2A or 3A adapters from Robu are of really poor quality. The output voltage drops to less than 2V when the load current is increased to around 1A. This is NOT the first time that the Orange branded stuff has turned out to be of poor quality. In the end, you get what you pay for.
