The power supply itself seems quite decent, but the cable / plug... not so.

Not my best work, but I was disgruntled.

You need ad least 1.5mm² to handle 16A safely. 0.5mm² is simply not enough! But does the actually have 0.5mm² of copper inside? Let's check!

When I cracked it open, I actually saw the solder 'joint' break. Made by a proud master-solderer, no doubt.

Hmmmm. Each wire has about 20 strands. Diameter 80µm. There's just NO WAY that adds up to 0.5mm². Depending on how I calculate the cross section (multiply strand cross section vs. measure wire diameter with air gaps), I end up with values between 0.005mm² and 0.15mm² - NOT ENOUGH.
Is that really copper?

I tried to twist the strands together. They immediately sprung back. They're very flexible, but too springy.
