Facmogu 3V-12V 5A 60W Adjustable Power Supply with LED Display, Variable DC 3V 5V 6V 9V 12V Universal AC/DC Adapter, 100V-240V AC to DC 3-12V Switching Power Converter Multi-Voltage Regulated Adaptor

Worked smoothly and easily with good readout.

Works well for my application, which is to power a 12vdc fan. Workable voltage range is 3.2 - 12.2 volts. Control knob does have a off position, is very sensitive and does not use its full range of motion to adjust voltage. Have left it on continuously for days and does not heat up or get warm.

This little variable voltage PSU does the job and can supply the current for most things. The only downside is the way it does things internally means the voltage is never the desired voltage when you plug it in (not okay), or immediately after you unplug it (this is okay). Basically, never leave your devices plugged in to this PSU. Always plug in the PSU and wait for the voltage to stabilize first. And unplug your device while the PSU is still on, then unplug the PSU.

Power supply gets very hot after being on for 30 minutes and starts turning on and off. I’m buying another brand, this one seems like a fire hazard.

Delivered very quickly, but I found that when powering 6V LED lamps (for pinball, juke box and vintage auto uses etc, AC or DC) the lamps flickered at 6V output. When I tried the same bulb on my bench top DC supply the lamps flickered at did not flicker. The output from this sweet little power supply is NOT smooth DC. I suspect it is simply rectified AC with inadequate capacitors to smooth out the rectified cycles. I am returning it. Not sure how I will solve this for my miniature diorama.

Good for testing and short-term use. Despite claiming a minimum of 3V, I couldn't get it to reliably go below ~3.45V. Also, the voltage tends to slowly drop over time (or at least the reading slowly falls.) Other than that though, it works well enough to use with electronics projects and can supply the claimed 60W.

great product. Highly recommend

I'm using these for landscape lighting using 16.4 ft cob strips with 1260 LEDs each, @max 12vdc. Adjusted to 7.25v the strip begins to glow. @ 8v= .22amps, 1.7watts. /@8.5v=.53a, 4.5w. /@9v=.86a,7.8w. /@9.5v=1.2a, 11.3w. /@10v= 1.5a, 15.3w. /@11v= 2.2a, 24.5w. /@12v= 2.9a, 34.6w. I have 5 strips and it lights my yard to a nice glow @8.5v for 22.5 watts total. Amazing the amount of light for little energy consumption. For adjusting zones independently, we are using one power supply for each strip using a weather enclosure for protection. Very pleased with these so far.

I use this for electrosynthesis and other electrolytic experiments and it works quite well. Output is stable and accurate to the display. Better then average for made in china quality. No complaints after a month of use

Bon produit

works great , will do biz again

Set at 5V to power up a couple of ESP32 CAM board yielded these devices inoperable, crashing, restarting and eventually failing even though same devices worked fine with a cheap fixed 5VDC power supply. Suspect the power supply was rather 'noisey' at that voltage. Also, the adjusting dial is very sensitive at that voltage level. Look elsewhere.

Combines the 3V-36V 3A model (LED display) with 3V-12V 2A model (no LED display) . This combination model is spec'd at 12V 5A and is rather unique. Output and readout is accurate. Voltage adjustment dial is non-linear but not as sensitive as 3v-36V 3A model.
