Purpose-built power for G4 Doorbell

This 110 VAC supply is made specifically for the Ubiquiti G4 Doorbell and plugs straight into a standard US outlet. It ships new with a six-metre cable and two spade terminals ready for the doorbell's low-voltage input. Installers who need a direct replacement or a spare for that model will find the correct voltage and connector here.

Input and output ratings

The unit accepts 110 VAC at 60 Hz with a maximum draw of 1 A and delivers 20 VAC at 0.7 A to the doorbell. This fixed conversion is the single specification that determines compatibility; any doorbell or accessory requiring a different secondary voltage or current cannot use this supply. The operating range spans -10 to 40 °C and 0 to 95 % non-condensing humidity.

Cable reach and enclosure limits

The six-metre lead gives roughly 19 feet of routing freedom from the outlet to the doorbell location. Beyond that distance the fixed cable cannot be extended without splicing, so runs longer than the supplied length fall outside the design. The polycarbonate jacket measures 64.8 by 63.4 mm and weighs 496 g, setting the physical footprint for mounting.

Questions about this item

What does the 20VAC 0.7A output actually deliver to the G4 Doorbell?

It supplies 20 volts AC at up to 0.7 amps, matching the doorbell's required input so the camera and chime operate without a separate transformer.

The plug is rated for 110VAC 60 Hz — will it work on a standard US household circuit?

Yes, the unit plugs directly into a North American 110-volt 60 Hz outlet and draws a maximum of 1 amp.

How much clearance does the 63.4 mm deep polycarbonate jacket need behind the wall plate?

The enclosure measures 64.8 mm in diameter by 63.4 mm deep, so allow at least that much space inside the mounting box for the jacket to sit flush.
