Doorbell Transformers & Wire

Wired Doorbell Transformers, Doorbell Wire, & Batteries​

Wired doorbell transformers are electrical devices that step-down the high-voltage electricity in your home to a lower voltage compatible for wired door chimes and wired doorbell push buttons.

The small table below shows the different wired transformers we carry at  Although we do not offer the largest selection, we have the necessary bases covered when installing or replacing your wired chime.

We are often asked questions about using a wired doorbell in conjunction with a or Hello Nest video doorbell.  We suggest you visit their support pages, but we do offer this tidbit.  Video doorbells tend to use more amperage than a standard wired door chime.   Coupling the video doorbell with your wired chime requires even more amperage and most doorbell transformers don’t have enough power.  We would recommend the DH910 for these purposes.
