    • Using this one with eufy camera doorbell
Works good and does what it's supposed to. It's slightly hugher than the 24V it claims but that's not a bad thing. Works well to power my camera doorbell. So far no complaints we'll see if it's durable and how long it lasts.

Packaged well, works well, did exactly what I wanted it to do, decent price. Nothing else to add....

    • Works for 2 digital chimes
After moving into a new place, the doorbells did not work (one chime upstairs, one chime down). After attempting to replace the chimes and running into the same issue, I replaced the transformer assuming it was blown. Same size transformer didn't solve the issue, but this sure did!

    • Died after 3 months.
Installed in September for my ring doorbell. Worked fine until recently when the app informed me the battery was low. Disconnected the bell wires to check output voltage. It was zero. Disconnected transformer and measured impedance on input and output windings. Impedance was infinite on input side! Transformer is toast. ... show more

    • Excellent choice
I purchased this transformer to upgrade an old doorbell system to have enough power for a Ring doorbell (line-power, not battery). Slightly bigger than what I had, but it mounted better than the original!

    • Used for Ring and Nest Doorbells Camera's
The transformer in my house did not have enough power to work my Ring Video Doorbell nor my daughter's Nest Video Doorbell. This did the trick.

    • Great for a Video Doorbell
I added a "Smart" doorbell to my house but the actual mechanical doorbells stopped working (there were two in thr house on different levels). I replaced the existing 16v transformer with this one and everything works great now...guess there just wasn't enough juice.
