Review: This works! - Helped us setup our Simply Safe doorbell. It was simple to do and we’ve had no issues.
Review: This is the one! Solves the Doorbell Pro issue. - OhmKat finally figured out and solved this video doorbell issue that has plagued many people trying to power their doorbell. I installed this one and it is working well. A bit more info: Before this one, I used a different transformer that was rated correctly and should have worked with the video doorbell pro. In fact it did work for awhile, but at some point it stopped working, and I think it may have even burned out my doorbell. The voltage on the other transformer was just a bit higher than on the OhmKat, and should have worked, but it didn't. When I researched this issue, I found that many other people have had similar issues, but NOT with the OhmKat! So, this is the one I highly recommend. I don't use the connector that allows you to add a wireless doorbell, but I think it is a super useful feature because the addition of a wireless doorbell is needed in most cases. In my case, since I already had the other transformer wired up to my video doorbell pro, I actually just cut the old transformer wires and spliced this OhmKat wires to them. It worked quite well and kept me from having the re-run the wires through my wall to the video doorbell. Note: If you are like me and you were using something other than the OhmKat, and your video doorbell stopped working, then you may need to get a new/replacement video doorbell along with the OhmKat to get it to work again. It seems that the other set-ups tend to somehow burn out, and the OhmKat does not.

## Questions & Answers

**Q: Is this just a 20v ac power supply or is there something special besides the led light?**
A: We bought 2 of these power supplies for our Simplisafe smart doorbells.  They are #1 for this purpose

**Q: Can it be used with a blink doorbell?**
A: https://www.amazon.com/dp/B0B781S8B7 this is specially made for blink with the right instructions.

**Q: Can i add a hard wired chime to doorbell?**
A: Yes, it is for a hard wired chime doorbell. I had to buy an adapter to pull in for the one I installed for my parent, since there was not connection to the electrical panel.

**Q: This states that it is a video doorbell.. so does it take video of who is at your door? I do t see where it shows this info**
A: Sorry, it is not a video doorbell.  It is a video doorbell power supply only.  You have to buy the video doorbell separately.

### ⭐⭐⭐⭐⭐ Works like a charm.
*by K***S on July 6, 2024*

Ordered this last night for overnight delivery. Got up and it was here, so, good job on that for sure. The last folks that owned my house cut out the existing doorbell for some reason and I wasn’t looking forward to running new wires and installing all the equipment. I went to Amazon to look for a doorbell transformer and it suggested the OhmKat plug. Got it installed in just a few minutes, it’s really easy. It just plugs to an existing outlet. Doorbell came right up. I set it up with my SimpliSafe base station and it works like a charm. I would definitely recommend this to anyone with a SimpliSafe alarm system that doesn’t have existing wires to the doorbell.
