    • Great for wired camera doorbells
This doorbell transformer worked great for wiring my Eufy camera doorbell. The 120V to 240V conversion was exactly what I needed, and the installation process was much easier thanks to the clear and detailed instruction manual that came with it. The instructions were easy to follow and helped make the setup straightforward. Overall, this was a great upgrade and a reliable solution for powering my doorbell camera. ... show more

    • Used this transformer in Stem kits before with no issues.
I am changing my one star review to a five. The issue below was caused by me connecting two transformers to a common 24 VAC output, wiring error on part. After attaching 120 vac to the whittle and black wires for 120 vac input and the 24 vac output. Without any loads attached to the 28 vac leads the transformer heated up and failed with smoke and the smell of burnt electronics. I’m still debating if I did something wrong or it was defective. ... show more

    • Diagram does not match the actual transformer.
Review Image by Buyer
Bad diagram. It does not match the color on the transformer and the transformer is not marked. I used the diagram in the photo to power it up. It burned it.
