Review: Great for powering fans - I got this to power some fans I had harvested from my old computer case before switching to a larger, newer model of the case I was using. Currently I use one of these at work to power a fan to increase airflow and it's been working great since I've bought it last year. The power going through it is consistent based on my measurements and I never heard my fan suddenly speed up or down as well. I plan on eventually ordering more for the other fans I harvested for other projects such as cooling my Nintendo switch or for ventilation purposes. Overall I highly recommend this to people looking to repurpose computer fans.

Works perfectly for powering a computer case fan for a project I have. Nice build quality, great price.

### ⭐⭐⭐⭐⭐ It works!
*by E***D on February 25, 2025*

This is a 12v 1 amp plug in adapter to covert 120v AC power. It has a connector for a 3 pin computer fan. I plugged this in and it worked instantly to power a 12v computer fan being used to cool a free standing gateway/nvr device. Soon after, the internal temperature of the device dropped 20 degrees C. This adapter is working fine. It is a bit hard to unplug the fan connector from the adapter’s connector. But this is attributed to the type of connectors being used, which has a tight locking tab that needs to be lifted to unplug. I am pleased with this item.
