I am using this to replace a 16 volt transformer to power a Reolink Video Doorbell. It appears to be working and continually powers the doorbell. I wish I had bought the Reolink battery version WiFi doorbell but this non-battery version is working flawlessly with this transformer.

Had to upgrade an old 14v transformer for the higher 20v requirement for the 2nd Gen Nest doorbell. Easy to install. Good included wiring and connections.

The transformer is fine and price is reasonable but the instructions show a different unit so that could be a problem for some folks and that is really inexcusable so deducting one star.

The old one failed, I replaced it with this and now my doorbell works again. This review is not insightful… It looks so much better than the original one and looks great next to my furnace…. It works. All I care about.

Based on the good reviews I bought one of these and put it in my new build rental condo that wasn't built with a transformer. I ran wire for it and installed it in a good spot. I know what I'm doing. I'm using an Eufy doorbell camera. All seemed well, then all of the sudden, out of nowhere, the camera lost power. I checked the transformer with my multimeter and it's outputting nothing. No signs of anything burning out, no corrosion, nothing. I figure it a fluke, and bought another one. Same thing happens in three months time. My power is good in the unit, I know that's not the issue. Fool me twice...
