Upgraded a doorbell pushbutton with a Wyze V2 video doorbell. This transformer has enough power and was really easy to install. Recommend this to anyone.

Easy to install. My Ecobee doorbell camera now works perfectly and no longer gives the "low power" error.

One day my Ring Pro 2 stopped working. After verifying that the circuit breaker was fine, I was reading 0 volts at the doorbell wires, leading to the issue being with the transformer. I purchased this transformer based on the specs and overall positive reviews.Sad to say, this transformer arrived dead. I installed this transformer with the wires exactly as the old one was wired. 0 volts on the output side, 120 volts on the input side. I went to my local home improvement store and purchased a $19 transformer with a slightly lower power output. That one worked perfectly out of the box.I was bummed out to be one of the few unfortunate people to receive a dud. I liked the fact that you can install this transformer on a metal j box punch out. Very clean install

The Google Nest Gen 2 doorbell worked fine with regard to camera and notifications but was unable to activate the indoor chime. The existing doorbell transformer could only deliver 20V and given the long length of wiring to the transformer that was insufficient to power the chime. Upgrading to the 24V Auspow transfomer solved the problem. I would have given this 5 stars but the transformer (heavy item) was packaged in a padded envelope not a sturdy box. During transit the mounting flanges of the transformer were bent. Fortunately, it was easily straightened and had no effect on installation or operation.

Works good and does what it's supposed to. It's slightly higher than the 24V it claims but that's not a bad thing. Measures 24.5V AC. Works well to power my camera doorbell. So far no complaints we'll see if it's durable and how long it lasts.

Previous doorbell transformer was underpowered to keep up with the demand of my new video doorbell, so decided to upgrade to this as Eufy suggest something 40VA. Install was a simple swap as all the wiring was already there. Doorbell has worked without issues since, and no more charging batteries.

The Auspow Doorbell Transformer 24V 40VA impresses with its decent build quality. The weight of the transformer gives a sense of its robustness. The transformer operates silently even under full load, which is a positive aspect. It remains cool when there is no load, indicating efficient operation. The no-load voltage measures at 27V.For a full-load test, a 12.1 ohms power resistor was used as a load. The terminal AC voltage recorded was 23.2V. This voltage corresponds to an AC current of 1.92A. Despite the heavy load, the transformer operated quietly and remained cool during the brief seconds of the full-load test. This is a good indication that the transformer handled the load comfortably. It should be capable of powering most doorbell cameras, even when accounting for wire loss. However, it’s important to ensure that the doorbell camera can handle a 24V AC voltage. In conclusion, this product has proven to be highly satisfactory for its intended purposes.
