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.

Very good Ac to 12volt adapter. Works great, excellent packaging, fast delivery.

It works perfectly on my laptop cooling pad, I needed longer cable and this works well, I was happy to know it worked well and shipped on time as well.

It works wreat

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

My lights were getting dim on the old transformer that was 8 years old. Plugged this in and boom, back to new brightness!

Perfect replacement

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.

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.

Works perfectly so far to replace defective original adapter that came with some led lights purchased from other seller.

Funciona bien. Buena calidad.
