120W Universal Power Supply Adjustable DC 3V ~ 24V Variable Switching AC/DC Adapter 100V-240V AC to DC 24V 5A Converter with 14 Tips & Polarity Converter - 5000mA Max

This power supply has been reliable for many pieces of electronics for me to test with. The Voltage tends to drift up slightly when it's used for a while, but only on the order of .1 to .2V. My unit does not get very hot, is not noisy (no audible sounds). The size is nice: some may not like that this is of the style with a box in the middle of the cable, but this does mean it doesn't take up a large space on a power strip or outlet to block other available ports.

I run cooling fans with this supply, works great, no problems and the accessories are handy to have for a quick set up.

Okay, this is tough. It does work as expected.The main observations are that (a) the knob is VERY easy to turn and knock, (b) the adjustment is continuous and not in steps like (3, 4.5, 6, 7.5 volts) and (c) reaches the maximum voltage at like the 3/4 point making it more sensitive to adjust in the lower ranges.The result is that it is rather finicky to set and must be left alone to avoid changing the voltage.So, it works but the knob brings practical usability into question, hence the loss of a star.BT recommends with practical reservations

I love this thing! I frequently repair friends' laptops & this works with every different brand & type I've run across. Easily adjustable voltage & simple to switch out plugs.

the order was was complete, well packaged and arrived early, this is the third product i have purchased all work well

This is a great little power supply for providing various voltages to random devices you lost the charger to. I found a used camcorder at Goodwill for $5 that didn't have a power supply. I only needed it for a few weeks while I converted old family videos from High8 to digital. This had the right size barrel connector to swap into it and I dialed in the correct voltage for the camcorder. No muss. No fuss. Completed my project and now I can donate the camera back to Goodwill for someone else to use (but keep this little beauty around).One thing of note that I wish they'd improve, however: The dial is SUPER touchy. I'm talking "breath on it and it'll jump by .1V" kind of touchy. I highly recommend dialing in the voltage BEFORE you attach it to anything, as the sweep is very fast and very twitchy until you dial it in.

Pretty good quality item for the price. The voltage selector is a dial and is VERY touchy causing the voltage to 'float' (kind of like how an analog video game joystick drifts). This makes it impossible to set and maintain exact voltage. Works fine for older electronic devices that will tolerate variation in voltage but not recommended for uses that require exact voltage settings.

This power supply is continuously adjustable from 0 to 24V. It comes with an assortment of power adapters to match most devices. This being, the voltage must be adjusted to the proper level. The power supply has a built in DVM.
