Thats right, I went though a couple of these, they are the single biggest consumer rip off I have ever encountered. After some investigation, I found it overheated quickly with NO load. If anyone tells me they have one and it works fine, take off the lid and have a look at the burnt PCB under the big coil
. Then watch smoke come out of it as you load it up. Maybe itll last weeks, maybe it wont.
The killer closer is, read the small print in the manual, its made for "testing purposes only" for no more than a few minuites at a time
.
Even the guys at Jaycar laughed and said one they had in the shop powering some demo leds blew up within days.
After this little bit of fun, Im VERY wary of Power tech supplies. The linear ones seem OK, but dont load them more than half there rated current (or less, to be safe).
