Our take on the Ubiquiti UVC-G4-DOORBELL-PS UniFi G4 Doorbell Power Supply AC Adapter

This is Ubiquiti's optional plug-in power adapter for the UniFi G4 Doorbell. It replaces doorbell transformer wiring: one end connects to the doorbell's terminals, the other plugs into a standard US outlet. The 6 m (19' 8") cable is the hard limit, so it only helps when an outlet sits close to the door. Buyers without an existing doorbell transformer or chime wiring are the ones who need it; anyone with working low-voltage doorbell wiring can skip it.

Pros
  • Skips the doorbell transformer entirely
  • Simple two-wire hookup with spade connectors
  • Plugs into any standard US outlet
  • Official Ubiquiti part, so no compatibility guesswork
Cons
  • 6 m cable is short; most doors won't reach an outlet
  • Only for the G4 Doorbell, not other UniFi models
  • Adds a visible cable run and an outlet plug
  • No chime or transformer support built in

What reviewers say

Owners treat it as a problem-solver for installs without doorbell wiring. The common complaint is the short cable, which rules out many front doors.

What people mention
  • Cable lengthCriticisedOwners say the 6 m cable rarely reaches an outlet from the door, which limits where the doorbell can go.
  • SetupPraisedBuyers report a quick two-wire connection with the included spade connectors and no transformer needed.
  • CompatibilityPraisedIt is the official adapter for the G4 Doorbell, so it fits and powers the unit as expected.
  • ValueMixedSome owners feel a generic AC adapter would do the same job for less.

Questions and answers

Does it work with other UniFi doorbells?
It is made for the UVC-G4-Doorbell. Other UniFi models have their own power requirements, so check before assuming it fits.
What comes in the box?
The AC adapter with its attached 6 m cable and two spade wire connectors for the doorbell terminals.
Will it power a mechanical chime?
No. It supplies power to the doorbell only. Chime behavior depends on the doorbell's own wiring setup.
