My next job will involve investigating the transformer, but that involves dismantling part of the kitchen so it's a bit of a hassle. With a robust 12W capacity, this power supply can handle the demands of your Aqara Smart Video Doorbell G4 and many other compatible devices.

Manufacturer warranties beyond 12 months are supported by manufacturer only, and not by DoorbellWorld. Wired door bells can therefore be preferred if a system that draws more power is required, which would quickly run down battery operated alternatives.Transformers are normally external to the doorbell and are often positioned in the consumer unit, but can be positioned anywhere (they are ugly boxes are not normally visible).

The bell push could (unusually) be configured as a zero volt switch, with no useful voltage appearing at that end. Please note, the installation of this Video Doorbell model is intended to bypass the chime kit, thus disabling the sounds operation.

It provides a stable 12V DC output with an impressive 1A current rating, ensuring optimal performance.
