A few weeks ago I got this power supply off of amazon. I needed one that was moderately powerful and cheap for a robotics project. It actually did work well enough.

Long story short, one of my friends' teenage child shorted it out and melted a hole through the breadboard used to control the servos. Teens.
Thankfully not too much was ruined, but this claim here is clearly BS:
"With overload overvoltage overheating short circuit protection, multi-filter with magnetic interference."
"overcurrent protection"?!? As in when the burning wire turns into a fuse? Or "overcurrent protection if your breakers are working ".
"Overheating"? Well, it didn't explode. So that's a plus.
"multifilter with magnetic interference"? Umm.... what are they talking about? And since when was susceptibility to EMI a good thing?
"overvoltage"? I guess you'll notice when you load blows up. But I think they mean it is not a direct wiring from mains to your output. Actually though, it does seem to be around the rated voltage.
"Low operating temperature and long service life." Assuming you don't use it, of course.
"Good insulation performance, high resistance to electrical strength." WTF? I guess it didn't start arcing.
Miraculously it still seems to work fine. It supplies many amps, much greater than 6, when shorted. So I decided to have some fun. I used it to charge my 2.7V 500F supercapacitors, which were just sitting on the shelf. I didn't use any resistors. It kind of acted like a CC power supply. It charged 3 in series (166F) from 0V to 6V within 30 seconds. So I'd say it works pretty well. One interesting thing I noticed is a faint 60Hz hum when there is overcurrent.
So am I wrong to abuse my power supply like that? Or does it deserve it for all the BS claims? And will it get it's revenge by failing terribly? And thoughts in general?
