Works great! I have had to buy this 2 different times because my chickens kept pecking through our automatic door cord. Each time this product worked till my silly chickens found it.

I wrote a one star review for this product. My voltmeter showed these power supplies had an output of 32VDC. I was really mad. I decided that all power supplies probably had a similar problem, so I bought a nice 12VDC 2A voltage regulator with a nice LED readout showing the input and output voltage. It supported input voltages as high as 40VDC with an adjustment to set it to 12VDC output. I connected this power supply to the voltage regulator and the voltage regulator showed 12.4VDC as its input. Wait!! My trusty old voltmeter, with a new battery showed 32VDC. I ordered a new voltmeter on Amazon and the new voltmeter showed 12.4VDC for the output of these power supplies. I feel bad. I gave this product a 1-star rating and it wasn't a problem with this product. Instead my trusty, 20-year-old voltmeter let me down. I introduced it to my garbage collector and he took it to -- wherever they take my garbage. And now, I have rewritten this review as a 5-star review. These power supplies work great. Buy one. Buy two. Oh wait, they come 2 to the package. Buy two packages. Actually, I chose these power supplies because they are a single block plug with the wire. So many 12V power supplies have a standard wall plug and a wire that connects to a separate block which then connects to a wire that goes to the device. That's too much wire to have to deal with. I wanted a block that plugs into the wall. This is perfect.

Variable uses with amps from to to 9. Good opion

they work for my needs, would buy again

I use several Ring cameras around the exterior of my home. The cameras need better night lighting to catch creatures in the yard. So I purchased several IR (InfraRed) lights. Unfortunately, they included a small 12-volt 1-amp electrical adapter. Each failed within a few months. These 12-volt 2-amp units are a good price and connect easily to the IR lights. The first ones I purchased have worked for over a year. They are well-built and a perfect upgrade to my IR lighting system.

Just right everything works now
