Not great
Matthew Pherigo•November 24, 2017
Very sensitive pots, questionable stability, and leaks the mains signal at almost a volt peak-to-peak. I really wish I'd gotten something higher quality.
This would've been perfect if they didn't dunp all their money into making this "high rated". It can output 20 amps, but they could've gotten away with 1 amp and spent the rest of their time and money nailing down the quality.

Awesome

Why have I waited so long to get this really useful lab tool. I've been using a homebuilt Heathkit TriPower for years and often need higher voltage and or current. The simultaneous display of voltage and current for both channels is so nice, looks cool too.
Only slight complaint is single-turn nobs are sensitive, but thankfully they seem high quality and don't move around once set. The fan is temp controlled and is very quit when it rarely turns on.

So far, this looks like a good product

The product arrived well packaged and in good shape. I received the version with LED displays and orange power button.
I used a digital MM to check voltages on all 3 channels. All worked OK. The variable outputs go up to 32V, so up to 64V when used in series.
I tried the separate, series and parallel modes, they seemed to work as expected. I also tried the current limit function, which also seemed to work correctly. There did seem to be a bit of overshoot when powering up, but only a volt or 2. Still, need to be careful with low-voltage circuits, and connect after powering up.
As others have mentioned, it would be nice to have an output on/off switch, and the included leads are quite flimsy and cheap, although the line power cord is fine. The instruction manual is also a bit challenging to understand, but does get the point across.
Other than those minor gripes, I think its a good product and I'm looking forward to using it. I reserve the final star until after some actual use.

Greate value, performs well

I have used this now for a few weeks, and I'm very pleased. I received the version with LED displays. My usage is for bench testing audio equipment, usually using a +/- split supply. (NOTE: the manual is not clear on how to get the +/- sides to track, so here's the scoop: left button in, right button out, and use the right Voltage knob to control both sides) The supply performs well to specs. The metering is surprisingly accurate. The current limiting works well - saved my circuits several times. I did have to re-solder one of the cheap alligator clips, but I'm not complaining. My only wish is about the fan - it only has one speed and off. If you start consuming moderate power for a minute or two, the fan will start up, and it is kind of loud, and it takes a long time to turn back off. Would be nice if it also had a slow speed. But because of the price, I'm not willing to take off a star for this. Overall, I recommend this supply.
Great hobyist or beguinner. horrible cables supplied

very good so far, it does put out the 5 amps and about 32V per channel. it looks cheap but I dont think it is, someone here posted a good review about it. I tried shorting it and i saw no sparks and good quick protection. overall a great value for the price.
The banana/alligator cables with comes with are by far the s***tiest I've ever seen. Hand made, with those banana plugs you see here that come in a bag of 20 with a screw to hold the wire, and the alligator clips are plastiky and the solder sometimes falls off or not done at all. SERIOUSLY get yourself better banana cables if you're buying this and dont have any.
