Item is as listed

An easy installation and enough power for my new Blink doorbell cam. The size is slightly larger than my old one but the weight makes it feel very durable.

Needed to repair my doorbell after an outside electrical issue fried my transformer and a few other appliances. It replaced a transformer installed in 1980. Works perfectly.

Ok.. So.. I actually used this to fix a 50A Astron that had a blown secondary that was used for the regulator. Rather than replace a very expensive transformer, I used this to supply the voltage to the regulator. Had been working 24x7 for several months now, no issues!

Had a problem keeping my smart doorbell charged up and decided to try this transformer. I am not an electrician, but this was very easy to install. The wire quality is strong and doesn’t let off any heat. I now get the power I needed to keep my doorbell fully charged. Worth every penny.

Worked great- for a month.... I installed this about a month ago and now my Eufy E340 doorbell is reporting "unstable voltage." I have a Sense monitor on my main power, so it's not an input voltage issue, the only remaining cause is the transformer, which is very hot to the touch. Unfortunately, the failure happened after the return window closed and there does not appear to be a way to contact the manufacturer for support. I guess you get what you pay for.

Upgraded my doorbell transformer from 10v to this 40v transformer. A 10v will ruin your Ring doorbell very quickly.
