BOJACK Doorbell Transformer 16V 30VA AC Power Supply Thermostat 16 Volt 30VA Power Adapter Compatible with Ring Video Doorbell Hardwired Door Chime Transformer

I purchased a Doorbell camera, and could not get the chime to work with my existing transformer. I took a look at my transformer and it is only a 10VAC transformer. Works fine for conventional doorbell chime. I was curious if the 10 VAC was low for the camera. The camera works fine on the 10VAC transformer, but the chimes did not work.For kicks, decided to buy this transformer to see if it would make a difference. Sure enough...installed this transformer, and the chimes immediately started working with the mechanical chime adapter.The open circuit voltage on my original transformer was 16VAC, while this one is approximately 19.5 VAC (measured with a good Fluke DMM). As far as the transformer itself, it was perfect, three wires (black, white, green), mounting nut was provided. Seems well made, rivet is correctly pressed, laminated plates all look aligned, ground wire is installed between the body and the core. All good. installation took 10 minutes. An interesting observation is that they used Philips instead of slotted screws, but that's not a dealbreaker.

This was exactly what I needed for our Ring Doorbell. It works perfectly now.

This solved the problem where my Google doorbell would ring outside but not actuate the indoor mechanical chime box. Thanks!

Item was east to install, use electrician if you don't know how or are uneasy about electricity. 4 stars due to power coming in at 28.5v

This is exactly what I needed to enable my doorbell camera to work properly. The original transformer that was installed in my house was, I think, only 12v. The lower voltage of the old one kept giving me connection problems and wouldn’t ring properly. I kept having to reset the doorbell camera. Now that my brother-in-law installed it, my doorbell and its camera work perfectly.

Excellent item work very good

After I installed a new Wyze V2 doorbell camera, my doorbell chime would no longer work. The transformer that powered the doorbell was an older 16v 10va unit. I replaced the older unit with this 16v 30va transformer and everything works perfectly now. It is easy to install if you are a do it yourself person and comfortable working with electrical wiring. Shipping was fast and the price was right.

Only put out 15v as measured by UniFi doorbell. Worked for 19 hours then took the doorbell and chime out when it died. Avoid.
