Ubiquiti U-POE++ PoE++ Power Injector Adapter
Overview
The Ubiquiti U-POE++ is a 60-watt external PoE++ power injector designed to supplement power delivery in UniFi network deployments. Operating at DC 48 volts, this midspan adapter bridges the gap between standard 30W PoE+ infrastructure and the higher power demands of advanced wireless access points, compact network switches, and powered IP cameras that require PoE++ input. Unlike full cabinet-level power supplies, the U-POE++ delivers point-of-use flexibility — critical when your existing switch lacks sufficient PoE++ budget or when adding high-power devices to an established network without replacing infrastructure.
Key Features
- 60-Watt Output Capacity: Supplies 60W at DC 48V — enough to power a single high-demand device or split across multiple lower-power loads, reducing the need for per-device 12VDC adapters or full PSU replacements.
- Single RJ45 Port Design: Connects directly between your network switch and the target device via a standard patch cable. No bulky wall-mount enclosure or complex cabling — simplifies installation in office, education, and enterprise environments where space is limited.
- PoE++ (802.3bt) Standard: Delivers power over the same twisted-pair copper that carries data, eliminating dedicated power runs and reducing cable clutter on overhead racks or wall conduits.
- Ubiquiti UniFi Ecosystem Integration: Engineered to work seamlessly with UniFi access points, controllers, and network devices. Also compatible with third-party equipment that accepts PoE++ input via RJ45 — check device datasheets to confirm voltage and wattage compatibility.
- External Form Factor: Compact external adapter footprint means it can be mounted on a wall, rack shelf, or tucked behind equipment without requiring internal device modifications or DIN-rail space.
- DC 48V Input/Output Specification: Industry-standard voltage ensures predictable performance across certified PoE++ devices and minimizes compatibility surprises compared to proprietary voltage schemes.
Integration & Compatibility
Deploy the U-POE++ in environments where your existing network switch provides PoE+ (30W) but your device requires PoE++ (60W+). Common scenarios include upgrading to a Ubiquiti IP camera or access point in a retrofit installation, adding a second powered device to a single PoE++ switch port, or provisioning a temporary high-power device in a lab or staging environment. The single RJ45 output makes it suitable for point-to-point injections; if you need to power multiple devices simultaneously, plan for one injector per device or verify that your target device supports power splitting.
Integrators deploying IP cameras across warehouses, manufacturing floors, or multi-building campuses often encounter legacy PoE+ switches that must remain in service. The U-POE++ avoids costly switch replacement — inject supplemental power at the camera location and keep your switching infrastructure stable.
Installation Context
Physical installation is straightforward: place the injector near the powered device, connect the network switch to the injector's input, and run an RJ45 patch cable from the injector output to the device. Verify that your network switch port can deliver at least the device's minimum power requirement plus 5–10% headroom — mismatched expectations between switch capacity and device demand are a common source of intermittent performance. Consult the PoE power planning guide if you're managing mixed PoE+/PoE++ deployments across a large installation.
Frequently Asked Questions
Q: Can I use the U-POE++ with devices that only need 30W or less?
A: Yes. The injector is rated for 60W output but will safely power lower-demand devices — it simply won't operate at full capacity. There's no risk of overpower damage to a 30W device connected to a 60W injector.
Q: Does the U-POE++ require a separate power source?
A: Yes. The injector itself must be powered via an external AC adapter or from your facility's 48VDC supply. Verify that the power supply provided with the unit matches your electrical environment before installation.
Q: Is the U-POE++ compatible with non-Ubiquiti devices?
A: The U-POE++ is designed for Ubiquiti UniFi products but will work with any third-party device that accepts PoE++ input at DC 48V via RJ45. Always confirm the target device's input voltage specification before connecting.
Q: What happens if I connect the U-POE++ to a device rated for lower voltage?
A: Do not do this. Mismatched voltage can damage the powered device. The U-POE++ outputs DC 48V — verify that your target device is rated for 48V input before installation.
Q: Can I daisy-chain multiple U-POE++ adapters?
A: No. Each injector is designed to power one device per RJ45 output port. Adding injectors in series will not increase total available power and may cause unpredictable behavior.

The Ubiquiti U-POE++ solves a real pain point in retrofit and mid-density deployments: upgrading to higher-power devices without ripping out your switch infrastructure. At 60W output, the U-POE++ gives you breathing room to add one demanding camera or access point to an existing PoE+ network without the capital expense of a switch replacement.
Technical Highlights:
- 60W @ 48VDC Output: Enough headroom to power a single high-draw device or split power across multiple lower-demand endpoints. At 48V, you're operating at the PoE++ standard, so you're not fighting proprietary voltage schemes or compatibility surprises.
- Midspan Injector Architecture: Single RJ45 output means clean point-to-point installation — no complex power distribution backplane, no need to rewire your entire cabinet. Ideal for stagewise network upgrades where you can't afford downtime.
- Third-Party Compatibility via PoE++ Standard: Works with any device rated for 48V PoE++ input, not just Ubiquiti gear. Verify device specs before installation, but you're not locked into a single vendor.
Deployment Considerations:
- The U-POE++ itself requires external DC 48V or AC power — it's not powered by the network link. Confirm your power supply matches the input specification before plugging in.
- Watch voltage carefully: this adapter outputs 48VDC. If your target device is rated for 12VDC or 24VDC, connecting the U-POE++ will destroy it. Check device datasheets twice before closing the cable.
- One output port means one device per injector. If you need to provision multiple high-power cameras or access points, plan for one U-POE++ per device or confirm that your switch can deliver native PoE++ power.
Deploy the U-POE++ where legacy PoE+ switching infrastructure must stay in place but new deployments demand higher power — warehouses upgrading to camera systems, education campuses adding UniFi 6E access points to existing networks, or enterprise office expansions where switch replacement is a budget line-item you'd rather avoid.
