Facmogu DC 12V 3A Power Adapter, 100-240V AC to DC 12V 3A 36W Power Suppy with Barrel Connector 5.5x2.5mm & 5.5x2.1mm, 12 Volt 3 Amp Desktop Adpater 12V Switching Transformer AC/DC Power Converter

I always worry about buying power adapters because of figuring out what volts I needs with my monitors. This adapter I've had for a few months and it is working great! It feels and looks sturdy, it doesn't get really hot and has a pretty long cord length. I say it's worth the price.

The adapter worked fine and took the place of the original (defunct one). The only slight setback was that the new adapter's female connector was slightly different than on the old adapter and didn't permit current flow. I simply clipped off the new and spliced in the old. Potential buyers need to somehow check if the new female connector is compatible with the old before purchase if possible, if not at least be prepared to remove the new connector and replace it with old or find a coupling to convert the new to the old.

It worked perfectly!

Product works exactly as described and fit the items i used it for perfectly

It works as expected. Nothing fancy, but it doesn’t need to be.

Works great BUT my first one had a broken on/off switch and wouldn't work, too a long time to figure out the issue. The second one works great BUT the power supply is one (1) watt and wasn't enough to power the laser and motors, so I replaced it with a 10w power supply (overkill). If you need to rewire it there isn't any information about the laser and how to rewire it, you need to look it up on the Ali Express site, the information is there if you request the information form the manufacturer (they don't respond on the Amazon site).

Top quality replacement power supply for dead wall warts. Perfect for TiVos.

I purchased this as a replacement for my Sophos XG115w rev2 modem and it works flawlessly. I highly recommend this over the 30+ adapters if you are looking for something to power your Sophos firewall.

Es una buena fuente con variaciones menores al 1% del voltaje y da el rendimiento que requiere el aparato para el que la compre.

Me agrado mucho, era lo que necesitaba y se me hace de buena calidad, el cable quizá es algo corto.

12 volt 3 amp power supply. Purchased for $16.99 in November 2025. We bought this power supply to run our new BeeLink S13 mini computer. I ordered the computer from AliExpress since it was cheaper, but of course that meant it came with an EU plug. Enter this trusty little adapter. It’s a power supply, and it does exactly what a power supply should do—deliver power without any fuss. No noise, no heat issues, no weird behavior, and no surprises. It just works, and honestly that’s all I can ask for with something this boring but essential. A simple, inexpensive fix to keep the mini PC running properly. No complaints at all. TLDR It’s an inexpensive power supply that works exactly as expected and solved the EU-plug issue for my BeeLink S13. Simple, reliable, and worth the purchase.

Compré el adaptador porque el original de unas luces led de mi cuarto se quemó, proble este nuevo y se me funcionó, estoy muy satisfecho 😙✌️

Works as described, I needed a replacement 12 volt adapter for my led grow lights. This plugged right in and has been great for over a week now. I would buy again.
