COOLM 12V 4A Power Supply Adapter Transformer AC 100-240V to DC 12V 4Amp 48W Adapter 5.5x2.5mm Jack for CCTV Camera LED Strip Light

Didn't get hot from use the length of the cord is decent connected to the devices with given power quality seems nice.

I had to replace my Firewall router power supply. I gave this one a try and so far it has worked well. Seems of good quality and a good value. I would purchase again. Make sure you have the voltage correct for your device.

I USED THIS POWER SUPPLY FOR MY EX2 ULTRA CLOUD STORAGE, WORKS GREAT

I purchased two new PSU's for my two UPSTAR M280A1 PC monitors which I bought used and didn't have the correct power adapters. These monitors require a 12v 4amp PSU that have a maximum of 48watts. now they power on and work solid.

Worked as intended but my monitor can hit the 144htz refresh rate with it. It just shuts off but works fine in 60htz

This piece of crap gets INCREDIBLY HOT in normal use. I can't stand to keep my finger on it for more than one second and I have no doubt this thing could easily burn me. I bought two and the first one died after it was powered on for about 5 minutes on my desk in the sun. The other adapter I have is still working but now I'm worried it's a fire hazard. Don't buy this.

I ordered this because it matched the specs of a busted Schwinn stationary bike power supply I needed to replace. I've used it for about five months now and it's worked just fine. No issues at all. The wall plug, DC plug and AC-to-brick cord plug all fit snugly (something I sometimes have trouble with with other aftermarket power supplies). Both the brick and the AC and DC cords seem well constructed. I'd certainly order one again if I ever had a need.

Works fine for my device as a replacement AC-DC Adapter,
