UniFi Cloud Gateway Ultra: new USB-C gateway, not a used USG + Cloud Key
If the house is already UniFi, do not glue a used USG-3P to a Cloud Key. Buy UCG-Ultra new. Built-in Network controller. 2.5G WAN. USB-C. This is not Protect, and it is not a switch — see USW-Ultra for the PoE box.
UCG-Ultra: compact Cloud Gateway, 30+ UniFi devices / 300+ clients, 1 Gbps routing with IDS/IPS, multi-WAN load balance. Port layout is one 2.5GbE WAN and four 1GbE LAN. USB-C powered, adapter in the box. Maker max 6.2 W. Quad Cortex-A53 1.5 GHz, 3 GB DDR4, 16 GB eMMC, 0.96" status LCD. UI store 23 Aug 2026: $129 / $139 surcharge-incl. B&H printed $136. Newegg printed $132. Print the live tag. The Amazon card we fetched was a Generic listing at $189.99 — skip it.
The short list
| Box | What it is | Street, 23 Aug 2026 | Buy if |
|---|---|---|---|
| UCG-Ultra | Built-in UniFi Network. 2.5G WAN + 4× 1G LAN. USB-C. 1 Gbps IDS/IPS. No Protect, no NVMe. Maker max 6.2 W. | UI store $129 / $139 surcharge-incl. B&H $136. Newegg $132. Print the tag. | Already UniFi. Gigabit WAN. You want the controller in the gateway, not a used USG plus a Key. |
| Cloud Gateway Max | The step-up with 2.5G throughout and optional NVMe for Protect. Different SKU, different bill. | UI starts the Max around $199. Confirm the live card. | You need Protect on this box, or the WAN is already faster than 1 Gbps IDS/IPS. |
| Used USG-3P + Cloud Key | Two boxes. 1G WAN. No built-in controller. EOL hardware people keep listing as a “deal.” | We are not pricing used lots. The stack it replaces is $328+ new if you still could. | You like projects. Not the closet default. See used vs new. |
Skip
Skip used USG-3P and USG-Pro-4 lots. We are not affiliating them. Skip Amazon Generic cards that do not say Ubiquiti. Skip Cloud Gateway Max until you need Protect or more than 1 Gbps IDS/IPS. Skip this whole page if you are not already UniFi — Flint 2 in AP mode or cheap PoE is the other door. This is a gateway, not the fanless PoE switch.
