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

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,

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

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

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 great for ~5 months. Started getting messages from my Ring doorbell about low battery charge, then no charge. Found out the transformer just failed so wasn't keeping the batteries charged. Transformers used to last dozens of years.

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

I have an older 25 yr old house. When I bought a video doordbell, my fancy doodrbell chime wouldn't work. I thought it was the doorbell, so I bought a basic one. It still didn't work. Someone suggested a transformer. The hardest part was removing my previous one. This one was easy to install with the insturctions provided. Now I am able to use my fancy chime doorbell again. I couldn't be happier, and now, feel safer with the video doorbell also.

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

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

It’s quiet and gives the correct voltages but the markings on the unit could be a little more visible.

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.
