I bought this unit around 2 years ago, and it is still working just fine. It seems to be built well, and the ammeter on the front doesn't show any signs of the unit struggling to power my 55 watt amateur radio on either 2 meter or 70cm frequency bands. I would recommend this over the more expensive choices out there.

My Pyramid PS21KX 20 Amp Power Supply works great and provides a smooth flow of power all the way up to it's design limit... The unit is constructed extremely solid with obvious quality built into the design.

I received this as a gift a couple years ago, and it's going strong. I use it as a 12v source for special chargers that I use to charge the various types of batteries used in Radio Control airplanes and cars. I've used it in the sweltering heat of my garage in Central California, and in the cold of my garage in a much colder climate. I even dropped it once, and it's working great!

If I were to say there is a downside, it's that there's only one output pair. I rigged up a multiple output attachment that works fine for my needs. Two pairs of heavy duty binding posts and a project box from an electronic store plus some heavy wire and a couple banana plugs.

I purchased this power supply for my Icom IC-2200H Ham radio. I set it up, powered the radio up and it worked just fine.

I have had this about 8 months, use it to supply power to multiple battery chargers (charging Lipo batteries for RC planes) and I typically run it at the 20 amp limit. I like the dial showing the output in amps so I know when to stop adding more chargers on line. This device has performed really well, no complaints. If I were to do it again I would get a 30 amp charger so I could charge even more batteries at the same time. Because of losses in the chargers, I can charge about five batteries at 2.2 to 2.5 amps each.

I am using this to power an aircraft instrument panel that I am building. It will eventually be installed into an airplane with great difficulty, so I want to get it right on the bench. And I need 20A of 12-14V.

This product fit the bill just fine.

I ordered on Sunday for two day delivery and expected it on Wednesday. It arrived Tuesday.

There isn't much to say about a power supply - it is powerful, the ripple specs put it closer to a battery than an alternator powered aircraft or auto. (That's a good thing).

The only gripe is that the built in ammeter is a little on the cheap side. Digital would be great, but I didn't pay for digital. The needle is about 1/2 amp lower than the actual draw, as verified by a precision Fluke multimeter. I can live with that.

I have some great bench power supplies that cost several hundred dollars and have better features, but only put out 1/3 the power. So, all in all, this was a good fit for my application.

Excellent Product! Bought this as a source for my iMax Quattro B6 charger. It allows me to charge 4 different 3700 mah 3 cell lipos without any problems at all. Doesn't make much noise even when fan is on. I wish I'd bought it years ago.

This is a very sturdy made product you can tell it's made to last,it's not a cheap piece of trash you see when you by a lot of things. I was very impressed when I received this power supply and I'm still impressed after using it for a while now.

I've always fought vehicle electrical systems the hard way. Now I can test leads, lights and numerous lighting applications. This unit is real simple to use, comes protected from 'oops' and is ruggedly built. I wish I would have gotten this a long time ago.

This is a well made heavy duty 12 volt power supply that works great to power several specialized battery chargers I use with batteries in radio controlled model airplanes and transmitters.
I am happy with the purchase and the quick delivery on an international order.
