Ubiquiti POE-24-24W-G 24W PoE Adapter
Overview
The Ubiquiti POE-24-24W-G is an external Power over Ethernet (PoE) adapter engineered to inject 24 volts DC power into network infrastructure where standard PoE or PoE+ won't suffice. Built for Ubiquiti USIP-family devices and compatible PoE injection applications, this adapter delivers a straightforward power delivery solution without unnecessary conditioning or conversion layers. At 0.8 lb and compact in form factor, the unit integrates into standard racks and distributed network locations without consuming rack space or requiring permanent mounting.
This adapter is positioned for integrators deploying Ubiquiti access points, controllers, and infrastructure equipment in environments where proprietary 24VDC injection is the requirement. It bridges the gap between devices that demand 24V input and standard Gigabit network infrastructure.
Key Features
- 24W Power Delivery at 24VDC: Outputs exactly 24 volts DC at up to 24 watts, meeting the voltage and current demands of USIP-family endpoints. This eliminates voltage mismatch issues that can degrade equipment lifespan or trigger thermal protection shutdowns.
- Single Gigabit Ethernet Port: Power and data coexist on one RJ-45 connection, meaning you don't lose bandwidth or add cable clutter. Full 1000 Mbps throughput is maintained alongside power injection.
- AC/DC Input Flexibility: Accepts both alternating and direct current source power, accommodating varied power infrastructure in warehouses, facilities, or mobile deployments where AC mains or battery DC systems are available.
- External Adapter Form Factor: Sits outside the rack or cabinet, making it portable and ideal for temporary installations, proof-of-concept deployments, or remote site commissioning where rack real estate is constrained.
- Lightweight and Portable: At 0.8 lb, the unit is easy to transport between job sites or redeploy across distributed warehouse automation environments without logistics overhead.
- Direct Injection Without Conditioning: Delivers clean 24VDC directly to the endpoint with no intermediate power factor correction, isolation transformers, or redundancy circuitry—reducing cost and simplifying troubleshooting when issues occur.
Integration & Compatibility
The POE-24-24W-G is designed for Ubiquiti UniFi and USIP infrastructure, particularly devices listed in the manufacturer documentation as requiring 24VDC PoE input. Before deploying, verify your target device's voltage and power consumption in its datasheet—mismatched voltage can destroy equipment. The adapter's AC/DC input means you can source power from either wall outlets or UPS battery systems, making it adaptable to facility-wide power strategies.
In warehouse automation environments, this adapter supports sensor nodes, edge controllers, and access point clusters that run on 24V rails. Gigabit throughput ensures no bottleneck for real-time automation data or camera feeds running across the same network.
Frequently Asked Questions
Q: Is the POE-24-24W-G compatible with standard 802.3af or PoE+ devices?
A: No. The POE-24-24W-G delivers 24VDC, not the 48V or 12V supplied by 802.3af/at/bt standards. It is designed exclusively for Ubiquiti USIP devices and other equipment explicitly rated for 24VDC input. Connecting it to standard PoE devices will cause malfunction or damage.
Q: Can I daisy-chain multiple POE-24-24W-G adapters to power several devices?
A: Not without additional PoE switches or injectors. Each POE-24-24W-G has one Gigabit port and delivers power on that single connection. Scaling power delivery across multiple endpoints requires separate adapters or a managed PoE switch designed for 24V injection.
Q: What power source should I use for the AC/DC input?
A: The adapter accepts standard AC mains (110–240V) or direct current sources (typically 24–48VDC). Check the datasheet for exact input voltage ranges and connector specifications to avoid brownout or overvoltage damage.
Q: Does the POE-24-24W-G require any configuration or management?
A: No. This is a passive injection adapter—there are no web interfaces, credentials, or firmware updates. Connect the AC/DC source, plug in the Gigabit patch cable to your endpoint, and power is delivered. Troubleshooting is limited to voltage measurement with a multimeter.
Q: Is the adapter suitable for outdoor or harsh-environment deployments?
A: The POE-24-24W-G is designed for indoor rack or cabinet use. It is not rated for IP66, IP67, or extreme temperature operation. For outdoor access points, consider a weatherproof enclosure or move the power supply indoors and run outdoor-rated Ethernet to the endpoint.

The POE-24-24W-G (often searched as POE 24 24W G) fills a specific niche: deploying Ubiquiti infrastructure that demands 24VDC injection over Gigabit Ethernet. Unlike standard PoE++ solutions at 95W or more, this adapter is lean and targeted. At 24 watts output, it's not a power workhorse, but that's by design—USIP endpoints and UniFi controllers drawing 24W or less will run stable indefinitely. The key appeal is simplicity: AC/DC input acceptance means you can pull power from almost any facility source without negotiating voltage regulators or isolation transformers.
Technical Highlights:
- Dual Input AC/DC: Accepts 110–240V AC or DC sources, eliminating dependency on specific power distribution schemes and enabling deployment in sites with battery-backed or variable infrastructure.
- Single Port Gigabit Injection: One RJ-45 carries both power and 1000 Mbps data—no performance sacrifice compared to unpowered Ethernet, and no extra cable runs to manage.
- 24W at 24VDC: Precisely matched to USIP device specifications; undersized power supplies are a common source of instability in the field, and this adapter avoids that trap.
Deployment Considerations:
- Voltage Mismatch Risk: The hardest failure mode is connecting this to a device rated for 12V or 48V. Always verify endpoint voltage in the device datasheet before plugging in. A multimeter on the output confirms 24V before device connection.
- Single-Port Scaling: If you need to power 10 access points, you'll need 10 adapters or a multi-port PoE switch. Budget for that complexity early—it affects project cost and cable density.
- No Environmental Rating: Indoor-only. If your endpoint sits outdoors, the adapter stays indoors and you run outdoor-rated Ethernet to the access point.
The POE-24-24W-G is the right call when you're standardizing on Ubiquiti infrastructure in a contained facility—warehouse floors, office expansions, or branch site automation—and you already have stable AC or DC power nearby. Avoid it if you need multi-device power scaling or outdoor resilience without additional enclosures.
