Ubiquiti UACC-POE+-USBC PoE+ AC Adapter with USB-C Input
Overview
The Ubiquiti UACC-POE+-USBC is a compact AC-to-PoE+ adapter designed to inject power and data over Ethernet when a centralized PoE switch is impractical or unavailable. This accessory accepts USB-C input and delivers PoE+ (802.3at) output on a single RJ-45 port, making it a practical choice for single-device PoE requirements in remote or distributed UniFi Cloud Gateway installations.
Key Features
- PoE+ Output (802.3at): Delivers up to 30W per port via standards-compliant PoE+. This matters because it covers virtually all enterprise IP cameras and lightweight access points without requiring a dedicated power supply on the device itself — reducing cable runs and eliminating wall-outlet clutter at the installation point.
- USB-C Input Connector: AC mains power enters via USB-C, a common industrial connector. Simplifies cable management and interoperability if you're already using USB-C power supplies elsewhere on the network.
- Single RJ-45 Port: One Ethernet output port means this adapter is purpose-built for injecting power into one PoE endpoint. Not designed for daisy-chaining or switching multiple devices — if you need to power three cameras, you'll need three adapters or a PoE switch instead.
- UniFi Ecosystem Integration: Designed specifically for UniFi Cloud Gateway deployments where local PoE injection is required but switch-based injection is unavailable. Pairs seamlessly with the Ubiquiti IP camera line when using a gateway architecture.
- Compact Form Factor: Minimal footprint allows mounting near the endpoint device or gateway, reducing the need for long power cable runs to a distant cabinet or PoE switch.
- Standards Compliance: Meets IEEE 802.3at PoE+ specifications, ensuring compatibility with any standard PoE+ endpoint device, not limited to Ubiquiti products alone.
Integration & Deployment Context
The UACC-POE+-USBC solves a specific infrastructure problem: a remote site with a single UniFi Cloud Gateway that needs PoE power injection but lacks a nearby PoE-capable switch. Rather than running power to a switch or adding a dedicated supply, this adapter converts AC mains (via USB-C) into PoE+ at the point of use. Common deployment scenarios include branch office gateways, remote building access points, and single-camera monitoring sites where a full managed PoE switch would be overkill.
Because it outputs standards-based PoE+, any 802.3at-compliant device can attach — UniFi or not. This flexibility simplifies inventory if you're mixing vendor hardware in a distributed architecture.
Specifications
- Output: PoE+ (IEEE 802.3at), up to 30W per port
- Input: USB-C connector, AC mains powered
- Ports: 1x RJ-45 Ethernet (output)
- Compatibility: UniFi Cloud Gateway; any PoE+ endpoint compliant with IEEE 802.3at
When to Choose a Different Solution
If you need to power more than one device at a single site, a PoE switch offers better economics and cleaner installation than stacking multiple UACC-POE+-USBC adapters. For installations requiring centralized power budgeting, network monitoring, or redundancy, a managed network switch with PoE is the stronger choice. Similarly, if your endpoint device requires High Power PoE (PoE++, 802.3bt), this adapter's 30W ceiling will not suffice — confirm your device's power draw before ordering.
Frequently Asked Questions
Q: Can I use the UACC-POE+-USBC to power multiple devices?
A: No. This adapter has a single RJ-45 output port designed to inject PoE into one endpoint. If you need to power multiple devices, either use multiple adapters (one per device) or deploy a PoE switch with multiple powered ports.
Q: What voltage and current does the USB-C input require?
A: The adapter accepts AC mains input via USB-C. Refer to the manufacturer datasheet for exact input voltage and amperage specifications before connecting a power supply.
Q: Is the UACC-POE+-USBC compatible with non-Ubiquiti PoE+ devices?
A: Yes. Because it delivers standards-compliant IEEE 802.3at PoE+, any endpoint device that accepts PoE+ power will work — UniFi cameras, third-party access points, or other 802.3at-compliant hardware.
Q: What is the maximum power output of this adapter?
A: The UACC-POE+-USBC delivers PoE+ per IEEE 802.3at, with a maximum of 30W per port. Confirm your endpoint device does not exceed this power budget before deployment.
Q: Can I use this adapter in an outdoor environment?
A: The adapter itself is designed for indoor use. If you require outdoor PoE injection, mount the adapter indoors and route the Ethernet cable outside to the endpoint, or consult the manufacturer for environmental ratings before deploying in harsh conditions.

The UACC-POE+-USBC solves a real problem in distributed gateway deployments where you've got a single UniFi Cloud Gateway or access point sitting at a remote location but no switch infrastructure nearby to inject PoE. This adapter delivers PoE+ (802.3at, up to 30W) through a single RJ-45 port, powered by a USB-C input from AC mains. It's a straightforward single-port injector — nothing exotic, but exactly what you need when a full PoE switch is overkill.
Technical Highlights:
- PoE+ 802.3at Output (30W max): Covers nearly all enterprise IP cameras and lightweight access points without requiring wall power at the endpoint. The 30W ceiling is generous for most UniFi gear and third-party PoE+ devices, but confirm your endpoint power draw — anything over 30W will fail to activate PoE negotiation.
- USB-C Input: AC mains enters via USB-C, a standardized connector increasingly common in industrial deployments. Simplifies cabling if you're already standardizing on USB-C power supplies, though you'll need to pair it with an appropriate AC-to-USB-C power adapter (not included).
- Single-Port Architecture: One RJ-45 output means minimal footprint and zero switching overhead — pure PoE injection. If you're tempted to stack three of these to power three cameras, stop and cost a small managed PoE switch instead. Total cost of ownership favors the switch in multi-device scenarios.
Deployment Considerations:
- Confirm your endpoint device does not exceed 30W power draw. Many UniFi cameras and access points sit well under this, but High Power PoE devices (802.3bt PoE++) will not work with this adapter.
- This adapter injects PoE into a single Ethernet run — if you need redundancy or failover, you'll require a second adapter and a secondary gateway setup. Single points of failure are acceptable for small remote sites but risky for branch-critical applications.
Best fit: branch office gateway with a single camera or access point, remote building monitoring, temporary deployment needing quick PoE injection without infrastructure investment. Less ideal for multi-device sites — at that scale, invest in a PoE-capable switch.
