5.0 out of 5 stars Does the job great, July 18, 2010

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.

5.0 out of 5 stars Great power supply for those 12V RC Battery Chargers, December 23, 2010

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.

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.
