Buying notes

Is this the right fit?

Good fit when
Use this when a wired doorbell, chime, or compatible video doorbell needs the listed low-voltage power supply.
Look at another option when
It is not needed for wireless-only systems, and it should not be guessed at when the existing wiring or voltage is unknown.
Range reality
Check the listed compatibility and placement notes before ordering. Building layout often matters as much as the product rating.
Setup note
Confirm voltage and VA requirements before ordering. Turn off power before wiring, and use a qualified electrician when the transformer is inside an electrical box or panel.

The T1630 16V 30VA transformer is a common step-up transformer for wired doorbell systems that need more capacity than a standard 16V 10VA unit. The voltage stays at 16V, but the 30VA rating gives the circuit more available power for the chime, button wiring, and compatible video doorbell equipment.

Where this transformer fits

Use this transformer when the doorbell equipment calls for 16V and the load is heavier than a basic one-button chime setup. It is often used with longer wire runs, multiple wired chimes, and video doorbells from brands such as Ring, Nest, Lorex, Arlo, and Eufy when their installation instructions allow a 16V transformer with higher VA capacity.

Why 30VA matters

A basic wired doorbell only draws power briefly when the button is pressed. A video doorbell is different because the camera, Wi-Fi radio, speaker, microphone, and charging circuit can place a steady load on the transformer. If the existing transformer is old, unlabeled, or rated at 10VA, the system may buzz, run warm, drop voltage, fail to ring the chime, or cause the video doorbell to report low power.

Before replacing the transformer

  • Confirm your chime and video doorbell both support 16V AC.
  • Check whether the video doorbell requires a power kit, chime connector, or resistor.
  • Do not use a higher-voltage transformer to solve a VA problem unless the whole system is rated for it.
  • Have an electrician handle the replacement if you are not comfortable working near household line voltage.

Love this doorbell . Very loud , which is what we were looking for. No mistaking the sound like our previous one

★★★★★D. W.Sep 26, 2022

I bought this T1630 transformer along with a new Craftmade doorbell chime to replace the original 40+ year old Nutone doorbell and transformer in my home. I also installed a Lorex doorbell camera and wanted the larger 30W transformer to ensure enough power was available. The transformer is huge in physical size and mounts into an electrical box knockout hole but you can't tighten it up enough to where it won't move around which isn't good. Otherwise the transformer works great and provides sufficient power for both my new doorbell chime and Lorex camera...I highly recommend this transformer despite it's mounting design flaw.

I bought this to allow for the possibility of adding additional chimes. It is overkill for one chime on a short run, but on the other hand, there is plenty of power to ring my one chime very clearly. My one complaint is that it attaches to the box with a set screw rather than a nut (attaching with a nut is MUCH more secure).

I'm happy not only with my 16V 30 watt transformer but also your customer service to help me with this. We needed THREE chimes for this house and this transformer powers them perfectly. We got things wired and now we won't be missing any more deliveries. Thank you!

Good products good quality I recommend them.

I called 1800doorbell with a problem, and they resolved the issue by telling me what I needed and shipping it to me quickly. I did the repair this weekend and now we have a functional doorbell again.

★★★★★Donna G.Mar 23, 2021

Performed as indicated

★★★★★J D.Sep 4, 2020

First, their on line tech service answered my basic question, as contrasted with another source that had no clue. Then, in about 1 1/2 hours, I successfully installed a new Chime doorbell and heavier duty transformer (needed for use with a Nest Video Doorbell).

★★★★★Steven W.Apr 16, 2020

I am very satisfied with the doorbell chimer. Looks and works great!
