Customers say
Customers find the transformer offers good value for money, with a variable voltage range and adjustable power supply. They find it convenient to use and perfect for small design projects like telescopes and pumps. The power supply is also well-received by customers. However, some have reported issues with wire plugs melting or almost catching fire while unattended. Noise level is also a concern.

Fantastic Unit
It works flawlessly and being able to precisely adjust the voltage is a blessing.

Works on telescope conversion. Very steady voltage
I’m an astronomer and I want to do some limited astrophotography by putting a camera on the back of a driven telescope. I bought an old Meade DS-2000 114m Newtonian, with an Autostar controller, strictly for this purpose. Back in the day, the DS-2000 was a really good telescope, with a reliable tracking system. The big problem is that it only took 8 AA batteries, with no option for ac, or even a 12v battery pack.I’ve been doing this for 30+ years now. I bought the telescope, which appeared to be in excellent shape, but untested, from shop Goodwill for $54 delivered. I wasn’t disappointed. The scope looks almost unused. But I really don’t want to run it using AAA batteries.I bought this Transformer because of the variety of connections, including the double snap fitting, like you’d use on a 9v battery. The battery holder in the telescope is connected by one of these connectors.After getting the Transformer set, I tested it by using the alligator clip connection. It ran the telescope perfectly. This telescope uses 12VDC so I set the Transformer to 12v. The power supply is very solid and steady through the Transformer, which I tested for 40 minutes.The idea of using the snap connection didn’t stand the light of day; I realized I’d be running negative to positive, and vise versa, which obviously wouldn’t work unless I switched some wiring around. So, I just sacrificed the alligator clips by cutting them off, and soldering them to the wires in the Meade. This left the barrel, which I easily connect to the Transformer wire barrel, to power the telescope.I ran the telescope for almost an hour, watching the voltage readout, and telescope tracking. The voltage remained rock steady and the telescope tracked perfectly for more than 30 minutes, before needing correction (excellent for this telescope).

Mixed value based on need.
I have a radio that is convenient to use but batteries do not last as long as needed. I wanted a 6 volt DC power supply to use and a way to know which plug tip would fit various needs. My largest concern was many power supplies do not work well with radios (AM especially). The voltage is pretty easy to adjust in the range I wanted within a couple of tenths of a volt, and the VOM showed within a few hundredths of a volt on the display. The negatives are the radio needs negative on the center electrode and the power supply is only setup for positive. I was able to alter this using the included plugs with leads. However when plugged into the radio I only had hum. When the tip was close when plugging in the hum started and stopped when removed. This made it unusable for my intended uses. The radio on AM and some battery operated LED Christmas lights. A nice unit that stopped too short for me.

Great quality and worked perfectly
I switched a DC powered christmas treeTo AC. Worked perfectly and let me adjust the voltage so it can work with several different projects.

Nice product
Worked exactly as expected. Great price
NickitOff –
Such a great product!
I absolutely love this product! I have a recirculating sluice and this runs the pump great. I can adjust the water flow by adjusting the voltage.Love the included clips!
The Experimentalist –
Good power supply
This is a handy device. I looked at the output on an oscilloscope, and there was some noise on the DC. If you need really clean DC, you may want to add a capacitor across the output.

Torched my guitar pedal
First thing I did when I got this was to try it with one of my guitar pedals but instead of turning on, there was a pop and some smoke and now my guitar pedal is fried
