12V 5A Power Supply Adapter, AC100-240V to DC12V Converter Transformer with 5.5x2.5mm DC Output Jack for LED Strip Light,Wireless Router,ADSL Cats,Security Cameras

I purchased a small Beelink computer from Amazon a couple of years ago. It was working perfectly. Then it started to randomly shut off on me. At first I though it was the computer itself. However I determined that it was a simple "wall wart" power supply that came with it. I read the specs of the old supply off of it and ordered this one on Amazon. It was very inexpensive and I got it the next day. The computer is working perfectly with it!

Had a led strip on ceiling that started to go out and randomly blink. Changed the power source cause it kept pulsating green light to low green light. looked up model number and got this one. worked prefect and light back to normal.

Was nervous about using a generic cord to replace one used for under cabinet lighting. This one works like a charm.

Great card!

Working fine and voltage within spec. My load was about 1amp. Would have been five stars but the cord is way too short at about two feet. Two feet means you most likely will need an extension cord.

I had to return this product, as it wasn't suitable for my LED plant lights; I needed 5 Am to light up all lamps without flickering. However, I tested it on two lamps with 120 LEDs each, and it gave me stable light with no flickering.

Was using this to replace another 12v 5amp power brick that was installed in the sound system of a hot tub. In order to do this I had to cut both the supply cord and the dc output cord. This allowed me to see the wiring used. Although the supply cord (the incoming AC 120v) is thick that thickness is all the outer insulation. The 2 copper wires inside were so thin that that kept breaking just trying to strip them so they could be spliced. The strands of copper were whispers of copper and there were only about 6 of these whisper thin threads. The wiring in the old power supply contains at least 3x as much copper. On my wire strippers this wiring was 20g or maybe even 24 to 26 ( the higher the gauge the thinner) which means it's going to get quite warm if trying to supply a 5a load on the DC side. This power brick is NOT UL labeled and because of these wiring deficiencies I doubt it could earn the UL label. Use at your own risk.

The power supply is well-designed. If overloaded it temporarily shuts down and powers up again after a short delay powers up again. I purchased the 5A version which turned out I needed to be more for my purpose of powering a small tire air compressor. I may use it in the future for a different purpose.
