Best Door Bell Transformers of 2026

"I upgraded to this transformer after my old one couldn’t provide enough power for my Blink video doorbell. The build quality is impressive and it’s UL-listed, which gives me peace of mind about safety. Installation was a breeze and it’s been running flawlessly, powering all motion events and notifications without a hitch. If you need a dependable transformer for your video doorbell, this is an excellent choice."

"When I swapped out my original 1980s transformer for this one recommended by Ring, the difference was immediate. My mechanical chime finally works, notifications are instant, and features like night vision and the LED doorbell ring are all active. The transformer does get a bit warm, but nothing concerning. Four months in, everything still works perfectly, though my mechanical chime now has a slight buzz, which I’ve heard is common."

"My house still had the original 1970s transformer, which just wasn’t enough for my new Ring doorbell. Switching to this Ring transformer was simple and effective—I didn’t even have to rewire anything. Now both my traditional chime and the Ring doorbell are powered properly. It’s been running smoothly, and I’m hoping for years of reliable service."

"After months of use and several heavy rainstorms, the outdoor bell is still working great. The system was pre-paired and easy to set up, with solid range and customizable chimes.

Glad I made the switch for peace of mind."

"This transformer was exactly what I needed to set up my smart Arlo doorbell in my home with 110V power in Mexico. With the help of an electrician, the installation was smooth. Just a heads-up: the doorbell took a few minutes to power up after turning the electricity back on for the first time."
