**Product Review: Doorbell Transformer 24V 40VA**I purchased the 24V 40VA Doorbell Transformer to replace my old transformer, which wasn't supplying enough power to my Ring doorbell. The previous transformer only provided 12V, which caused the Ring's battery to drain quickly. In warmer months, it would last a few weeks, but in winter, it barely held a charge for a few days. This new transformer was exactly what I needed to resolve the issue.**Packaging and Delivery:**The product arrived promptly and was well-packaged to prevent any damage during shipping. Inside, there was a set of clear instructions covering various installation methods, depending on your doorbell setup and number of chimes.**Installation Process:**The installation was straightforward and required no additional modifications. It was a direct 1:1 swap with my old transformer. The previous unit was installed in a junction box connected to a light in an unfinished section of my basement, making it easily accessible.Here’s a quick overview of the installation steps:1. Turn off the power at the breaker and verify with a multimeter.2. Remove the three wiring connections (hot, neutral, and ground).3. Disconnect the doorbell wires and remove the old transformer.4. Install the new transformer into the same knockout. The new unit even came with a threaded nut to securely attach it.5. Reconnect all five wires, ensuring they’re snug, then restore power.**Performance:**After installation, I used my multimeter to verify the output voltage, which was 27V—an upgrade from the old 12V transformer. I also checked my Ring doorbell through the app, and it confirmed that it was charging properly.Another positive aspect of this transformer is that it operates silently. Unlike some transformers that emit a noticeable hum, this one is completely quiet, which is a huge plus for those who are sensitive to noise.**Overall Impression:**This transformer is an excellent replacement for my previous one and has eliminated the need to constantly recharge my Ring doorbell. The installation was quick, and the performance has been flawless so far.**Cons:**I did deduct one star because I could not find any UL certification on the unit or packaging. While it’s understandable that the product is made in China, I would have preferred to see some form of certification for safety assurance.**Final Rating: 4/5**This transformer is a reliable and efficient solution for powering your Ring doorbell.
