Ubiquiti POE-24-12W-G PoE Adapter – 24VDC 12W Single Port
Overview
The Ubiquiti POE-24-12W-G is an external PoE adapter designed to inject 24VDC power at 12W into compatible Ubiquiti network devices. This single-port adapter maintains full 1GbE data throughput while delivering a consistent 12W power budget, making it a straightforward, dedicated solution for Ubiquiti infrastructure deployments. Unlike multi-port PoE injectors, this adapter is purpose-built for a single device, eliminating complexity and unnecessary cost in smaller network segments or edge locations.
Key Features
- 24VDC 12W Power Output: Delivers exactly 12W at 24VDC — sufficient for low-to-mid-range Ubiquiti access points, bridges, and compatible edge devices. This fixed power budget prevents oversubscription and ensures predictable thermal behavior in racks or wall-mounted enclosures.
- 1 Gigabit Ethernet Port: Single RJ-45 connection passes full 1GbE data rates without bottleneck, allowing you to deploy this adapter in bandwidth-sensitive environments without penalty to throughput.
- External Form Factor: Compact, wall-mountable design fits behind racks or on vertical surfaces, reducing footprint and simplifying cable routing compared to inline injectors that hang off patch panels.
- AC/DC Input: Universal AC/DC input acceptance means you can source power from standard office supplies or industrial PSUs without custom adapters.
- Ubiquiti Ecosystem Integration: Designed to pair with Ubiquiti's standardized 24VDC product line — verify your target device specifications before deployment to confirm compatibility with the POE-24-12W-G.
- Lightweight (0.4 lb): Minimal weight reduces mounting load and simplifies repositioning if ring or cabinet layout changes.
Integration & Compatibility
The POE-24-12W-G functions as a dedicated power injector and is not a universal PoE solution. Compatibility is strict: only Ubiquiti devices explicitly rated for 24VDC 12W input will operate correctly. Confirm your endpoint's power rating in the device datasheet before ordering — mismatched voltage or insufficient wattage will prevent operation.
When deployed across a network switch backbone, this adapter does not draw on switch PoE budgets; it operates independently from wall power, freeing up switch capacity for other devices. This separation is useful in hybrid environments mixing PoE and non-PoE infrastructure.
Because this adapter is a single-port injector, it scales vertically: if you need to power multiple devices, each requires its own POE-24-12W-G unit and wall outlet. In centralized deployments, a managed PoE switch supporting 24VDC output may be more economical than daisy-chaining multiple injectors.
Frequently Asked Questions
Q: Is the POE-24-12W-G compatible with standard 802.3af or 802.3at PoE?
A: No. The POE-24-12W-G is a proprietary Ubiquiti injector delivering 24VDC. It does not conform to IEEE 802.3af (48VDC) or 802.3at (48VDC PoE+) standards and cannot inject power into devices expecting those voltage profiles. Verify your Ubiquiti device's input voltage specification — this adapter is for 24VDC-rated equipment only.
Q: Can I use the POE-24-12W-G to power multiple devices in series?
A: No. This is a single-port adapter with a fixed 12W output. Connecting multiple devices in series will exceed the power budget and may damage the adapter or connected equipment. Deploy one POE-24-12W-G per device.
Q: What power source should I connect to the AC/DC input?
A: The adapter accepts standard AC/DC supplies. For redundancy-critical deployments, use a regulated AC/DC power supply with UPS backup. For lab or temporary use, any standard office AC adapter within the input rating will suffice. Consult the datasheet for exact input voltage and amperage limits before connecting.
Q: Does the POE-24-12W-G require any configuration?
A: No. This is a passive power injector — plug in AC/DC power, connect the Ethernet port to your device, and power flows automatically. No firmware, no dashboard access, no commissioning steps required.
Q: Will this adapter work with non-Ubiquiti devices?
A: Only if a non-Ubiquiti device is explicitly rated for 24VDC 12W input. The 24VDC output is the critical factor; brand does not matter. However, Ubiquiti specs this adapter for their own ecosystem, so compatibility is not guaranteed outside that family. Test in non-critical circuits first if integration with third-party gear is required.

The POE-24-12W-G is a single-purpose tool — it injects 24VDC at 12W into Ubiquiti devices and nothing else. That narrowness is actually a strength: no feature creep, no unnecessary cost, and predictable behavior in the field. If your device roster includes Ubiquiti APs or edge switches rated for 24VDC input, this adapter removes the guesswork around power delivery.
Technical Highlights:
- Fixed 12W Budget: Unlike variable-wattage injectors, the 12W output is deterministic — your device either fits the spec or it doesn't. No thermal surprises, no late-night current-draw complaints from site techs.
- 1GbE Pass-Through: Full gigabit throughput means zero compromise on data rate. Even in latency-sensitive RF backhauls, this adapter does not choke the link.
- Passive Injection: No electronics, no firmware updates, no management interface. Plug, power, and forget — a virtue in remote or air-gapped deployments.
Deployment Considerations:
- Voltage Mismatch Risk: This is 24VDC only. If you accidentally connect it to a 48VDC PoE device or patch it into an 802.3at injector, you've got a short circuit problem. Label your ports clearly if you're mixing 24VDC and 48VDC gear in the same rack.
- One Device Per Adapter: Do not attempt daisy-chaining or power splitting. Each endpoint gets its own POE-24-12W-G. In a 20-AP campus build, budget accordingly — this is not a centralized solution.
- Input Supply Dependency: Power reliability rides on your AC/DC source. If that supply fails, endpoints go dark. In mission-critical backhauls, pair the adapter with UPS-backed power conditioning or use redundant supplies.
Best fit: small-to-medium Ubiquiti RF deployments where each AP or bridge node needs independent 24VDC injection and you want zero complexity. If you're wiring a 50-device campus, a centralized 24VDC PoE switch will be faster and cleaner. If you're powering a pair of remote APs from site-local supplies, the POE-24-12W-G is the right call — cheap, reliable, and absolutely transparent.
