I used this power supply to charge my Lipo batteries for my RC planes. This power supply worked fine when I was charging at 3A continuous. However, the Voltage dropped to an unacceptable level when I tried to charge at 5A. Even 4A did not work very well.

1.0 out of 5 stars Pyramid 5 amp supply, September 30, 2009

I needed a cheap supply for my home shop and that's what I got.
Having been in the electronics industry for 30 years, I can tell you that this is a piece of Chinese junk.
With a 3 amp load it shuts down on high temp in about 10 minutes.
After being used 3 times the power switch fell apart.
Very poor design from a thermal management perspective and poor overall quality.
I should mention, however, that I probably got what I paid for.
Not worth the expense of returning it since I can make it work with a couple of modifications.

2.0 out of 5 stars Nice, but not for continuous 5 amp, June 30, 2009

Bought for application using just less than 5 amps. While it does deliver 5 amps, it will only do so for a few minutes, then will shut off, resting comfortably for about 40 minutes, then back on. I needed to return as my application required 5 amps. Nice unit, but not for continuous use at rated capacity
