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

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.

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.

This power adapter is working for my application. I'm using it to provide 12VDC to an LED light strip.

It worked perfectly!

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

Exact replacement for a dead power supply to a WD MyBook 500 GB HDD. A tiny investment prevented me from turning toward a data recovery service. Was able to immediately access my data and offload to another drive that I have more confidence in. I'll continue to use the WD with this power supply, however this drive won't be in my archive lineup.

Works great exactly as described, I will buy from them again.

These are not safe adapters. They run too hot. I had an old one that had burned out, and I thought maybe it was just a fluke. I needed to replace it, so I purchased the same model here. It worked but also ran hot. Now here we are a few years later, and the adapter has the same burnt up look and it even damaged my floor. Even though it seems cheap and functional for providing power to a monitor, I cannot recommend this product. I need one that can consistently put out 3 amps without burning me or my floor.

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

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.

Funciona bien. Buena calidad.

Trabaja muy bien, baja una estrella por que tengo la sensación de que el cable del conector de 5mm es fragil, muy bueno

This is a good replacement to my old modem DC adopter. My modem's adopter output was 12V 1.5A. It was broken when power down and power on again. Only waited 15 to 20 minutes It can back to work. I replaced a old 1.5V adopter, but It was a little bit warm. So I decide to change 2A or 3A adopter. Facmogu DC 12V 3A is a perfect replacement. It works very cool. I believe it can last longer.
