Ubiquiti POE-15-12W PoE Adapter 15VDC 12W
The Ubiquiti POE-15-12W is an external Power over Ethernet adapter designed to supply power to UniFi devices that require 15VDC input. This adapter bridges the gap between standard 48VDC PoE infrastructure and devices with higher voltage requirements, making it necessary for UniFi deployments that extend beyond conventional power specifications.
Key Features
- 15VDC Output: Delivers 15 volts DC to UniFi access points, cameras, and network devices that specify 15VDC input. This voltage is higher than standard 48VDC PoE, meaning devices designed for 15V cannot use conventional PoE switches — you need this dedicated adapter to bridge that mismatch.
- 12W Power Budget: The POE-15-12W provides 12 watts of continuous power delivery. On a typical UniFi deployment, this is sufficient for lower-power access points and certain compact camera models; confirm your device's wattage draw against this limit before deployment to avoid undersupply.
- External Form Factor: Housed in a compact external enclosure weighing 0.450 lb, the adapter occupies minimal rack or wall-mounted space. No internal modifications to switches or controllers are required — simply insert the Ethernet connection and attach the power output to your target device.
- AC/DC Input: Accepts standard AC or DC input power, giving you flexibility in how you source the adapter's own power depending on your facility infrastructure.
- UniFi Integration: Built into the USIP Accessory Tech family, the POE-15-12W integrates into UniFi Switch and controller environments without requiring driver installation or special firmware — it is a passive power delivery device and works immediately upon connection.
- Manufactured by Ubiquiti: As an official Ubiquiti accessory, the adapter carries manufacturer support and is designed to meet Ubiquiti device specifications and compatibility requirements.
Integration & Compatibility
The POE-15-12W is purpose-built for Ubiquiti UniFi devices that list 15VDC as their input specification. Before purchasing, verify that your target device's power input matches 15VDC; if your device requires 48VDC or another voltage, a different power solution is needed. The adapter works within UniFi Switch and UniFi Controller deployments and does not require configuration — it is a plug-and-play power delivery component.
When planning a PoE infrastructure deployment, account for the total wattage of all devices on the same adapter. The 12W limit means you cannot daisy-chain multiple high-power devices to a single POE-15-12W unit. If you require redundancy or higher power headroom, consult network power supply guides to assess whether multiple adapters or a centralized power solution is more cost-effective.
Physical Specifications
The adapter is compact and lightweight at 0.450 lb, making it suitable for mounting in network closets, equipment racks, or behind wall-mounted UniFi controllers. It is manufactured in China to Ubiquiti quality standards.
Frequently Asked Questions
Q: Can I use the POE-15-12W with my standard 48VDC PoE switch?
A: No. The POE-15-12W is designed for UniFi devices that require 15VDC input. Standard PoE switches output 48VDC. If your device requires 15VDC, you must use the POE-15-12W as an external adapter between your PoE switch and the device.
Q: What happens if I try to power two devices with one POE-15-12W?
A: The adapter has a 12W total power budget. Connecting two devices in series or parallel will exceed this limit and risk undersupply or shutdown. Use one adapter per device, or verify that the combined wattage of your devices does not exceed 12W before connecting.
Q: Is the POE-15-12W compatible with non-Ubiquiti devices?
A: The POE-15-12W is engineered for Ubiquiti UniFi devices. Compatibility with third-party devices is not guaranteed. Verify your device's power input voltage and connector type against this adapter's output before use.
Q: Do I need a separate AC power supply to run the POE-15-12W?
A: Yes. The POE-15-12W itself requires AC or DC input power. It does not generate power; it conditions and outputs 15VDC to your UniFi device. Provide a standard AC wall outlet or DC power source to the adapter's input.
Q: Will the POE-15-12W work in my existing UniFi setup without reconfiguration?
A: Yes. The adapter is a passive power delivery device. Connect it between your PoE source and your 15VDC-input UniFi device, and it will provide power immediately. No controller configuration or firmware updates are required.

The Ubiquiti POE-15-12W solves a specific and common problem: UniFi devices that require 15VDC input cannot draw power from standard 48VDC PoE infrastructure. This adapter sits between your existing PoE switch and the 15VDC device, converting and delivering stable power without controller involvement. It's a straightforward piece of glue in a UniFi environment.
Technical Highlights:
- 15VDC Output: Non-negotiable for any UniFi device that lists 15V as its power input. Standard 48VDC PoE switches cannot directly supply this — the adapter fills that gap.
- 12W Power Budget: Sufficient for most low-to-mid-power UniFi access points and compact cameras. Confirm your device's wattage against this limit; undersizing here results in shutdown or instability under load.
- External Form Factor: Keeps your switch clean and avoids the need to retrofit internal power modules. Compact footprint (0.450 lb) fits easily into rack or wall-mounted installations.
Deployment Considerations:
- The POE-15-12W is a 1:1 device adapter. Do not attempt to power multiple devices from one unit unless you've verified the combined wattage stays under 12W — a common mistake that leads to brownout symptoms.
- You must provide the adapter's input power separately. It does not draw power from the Ethernet cable; it requires AC or DC input. Forgetting this is a quick way to spend 30 minutes troubleshooting.
- Verify your UniFi device's power connector type before purchasing. The adapter outputs 15VDC, but connector form factors vary across the UniFi product line — a mismatch means you cannot physically connect the adapter to your device.
The POE-15-12W is essential infrastructure for any UniFi deployment that includes 15VDC devices. If you're scaling a UniFi network and your documentation specifies 15VDC input, this adapter is not optional — it's the correct way to deliver power. For integrators standardizing on Ubiquiti, this is a reliable accessory to keep in stock for new installations and field remedies.
