Facmogu Adjustable Power Supply 9V-24V 3A 72W, Variable Voltage Adapter

Has digital voltage display and good voltage range, and is easy to adjust

Bought this as a replacement for duct fan controller, works well.

Great for the value. It did exactly what it was designed and powered up my thermal label printer. Only issue was control knob was touchy. With a good potentiometer it be a 5 star product, easily worth double the price.

Good

This would be just fine except that the adjustment knob only works in a small 90-degree span. It shows more than half a circle, but it only adjusts between at most 9 to 12 o'clock. It’s already maxed out ant 24V then, so for the entire wrest of the turn range it just sits at 24V. That abbreviated adjustment zone means it jumps very quickly every time you even breathe on the dial, making it very difficult to make fine adjustments. It's a completely unnecessary problem for them to have, and it's not just a one-off. I returned the first one for a replacement, thinking it was just defective. Nope. That's just how they are. Second one was exactly like the first.

Even when delivering the rated amperage it never complained. A little touchy dialing in an exact voltage, but very doable.

I liked everything about it for the price you can't beat it it holds the voltage you set and it was or is dead on. Plane on buying another on. Showed it to friends snd they bought it!

If you just need the adapter to power your gizmos, this should do the job...maybe. If you require CONSISTENT power without fluctuation, look elsewhere. I can set the adapter at 10V and look at it less than 2 minutes later and it's adjusted itself to 9.5V. I'd send it back, but the equipment that I was waiting for to use this adapter with took much longer to get here than it should have, so I didn't realize this until it was too late "/

Very good power supply. Precision volt meter. Perfect for any use. Extremely happy about the product. Checked voltage with a DMM at 21.7 volt on power supply and on DMM 21.6volts. recommend to anybody.

OK Parfait pour Arduino.

Handy for testing different items

Ended up buying 3 of these, great for turntable motors fine tuning.

It is adjustable, but starts around 8.6v, and under draw the voltage doesn't change. Voltage isn't as important as amperage for my application, we'll see over a couple days if the potentiometer is really doing anything, but it seems to do the job so far.
