72W Power Supply Adjustable 3V ~ 24V Variable Universal Switching AC/DC Adapter Minidodoca AC to DC Converter with LED Voltage Display and 16 Tips, for 3V to 24V Household Electronics - 3000mA Max

I bought this to power a circuit card I'm testing for work. I usually use a big bench supply to power the card. It's too big to be carrying around when I work in the field. This thing is adjustable from 12..24v and is small enough to put in the bag I use when traveling. The card has a regulator on it so I can't comment on how noisy this is but it works for me. It comes with a bunch of cables and connectors for connecting to existing stuff.

Works so far. It's not easy to fine tune but you will get within a range you need. Please set you device BEFORE you plug it into your device. Also be carful not to bump it, which will change it's output and may ruin your device. It's really a great and compact tool that you can combine with a set of various common plug sizes.

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.

I've been using this power supply for 3 months now for multiple different projects. still works great. highly recommend

Good price, no complaints.

This was defective...it was supposed to go from 3 to 24 volts, but only went to 4.5 volts. It also started getting really hot in just a minute, so I unplugged it. Unfortunately it was too late to return it for a refund by the time I got to use it.

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).

I have a small motor approximately the size of a D cell battery running an extremely light load. The motor bogs down with this power supply. Also the plugs on the additional cords are all male and need to be female. Adjustablility is great and works fine but doubt the watts. Buy bigger if you're on the fence
