Newhouse Hardware 3TRAN Tri-Volt (8vac/10VA, 16vac/10VA or 24vac/20VA) Transformer for for Ring, Nest and Standard Doorbells 1pk

Installs easily. Works great with new 5G door camera, supplying the perfect power

It works. Used for my video doorbell. Simple and effective.

My other 2 transformers were making humming sound constantly, original one was 16 volts 10 va then purchased a 16 volts 30 VA , both of the transformers made humming sound in chime specially when doorbell detected an object, and also when package guard was on in cam settings, had to return the transformer, Then I purchased this tri volt transformer ,it shows 28.66 on both of my Chinese multimeters, hooked it up to 24 volts settings ,no humming sound anymore , and no noise when it detects objects,, Transformer seems to be little warm to the touch , It being tri volt transformer it should work with all kind of door bell cameras,

I had a 1st gen Nest doorbell that was connected to a 10V transformer, so I needed to upgrade the transformer in order to support a 2nd gen Nest doorbell. Initially hooked this up on the 16V configuration, but my mechanical chime would not work although the doorbell received enough power to turn on. Moved this to the 24V configuration and both the doorbell and chime are working great. This transformer does have a very perceptible, disconcerting hum. Hopefully this does not indicate trouble. Will certainly update my review if something blows up. Easy to install if you are familiar with residential wiring. My transformer was conveniently located in the chime junction box. If you can replace an outlet or switch, you can install this with ease if you have access to your existing transformer.

stays warm but not hot, fair price, very quiet, and had for over a year

Worked with new Blink doorbell. Just make sure to set to manual chime in device settings after installation.

Why did you pick this product vs others?: I liked the possibility of using a different voltage doorbell at some point in the future, and the price was cheap, but it was noisy from the start. It started with a buzz I could hear six feet away, and a day or two later, it was so loud I could hear it through walls.

Excellent!

Excelente, me sirvió para conectar un timbre ring a la corriente.

A bit expensive but works well

This product is absolutely solid, it’s just unfortunate that it’s 120v, still giving it 5 stars because it’s SOLID and tri-volt out is impressive feature

Not uk compatible

Used this with the Ring Doorbell Pro. It works fine so that's as advertised. However the thing hums all day and night. During the day it's not noticeable but at night I can definitely hear it which is just annoying. Also be warned when this is running at full power it will get hot.
