Enough power for two Nest doorbells

Bought to replace an older 18V transformer since I wanted to install two Nest doorbells and didn't have enough power off the older transformer (one doorbell worked, one showed a power low warning) This did the trick and now both have enough power to run.Install was straightforward, just cut power and moved the wires over from the old transformer and mounted it on a punch out in the breaker box.

Pros

Used it to power two door bell buzzzers and a Unifi G4 doorbell camera. All works as you would expect.

Cons

Voltage not what as advertised
