This article covers Ubiquiti Networks 2.5GbE 30W PoE+アダプター。.

Overview

The Ubiquiti Networks 2.5GbE 30W PoE+ Adapter is a compact power injector designed to deliver both data and power to UniFi access points and other PoE+ devices. Unlike standard gigabit PoE injectors, this unit supports multi-gigabit speeds up to 2.5Gbps, making it an ideal backbone companion for Wi-Fi 6/6E access points that can benefit from higher throughput. Measuring 180×110×50mm and weighing approximately 0.7 lbs (317g), the white enclosure blends seamlessly with other UniFi hardware. It accepts 100–240V AC input, so it works worldwide with the appropriate power cord.

Connectivity & Compatibility

The adapter features two RJ45 shielded ports: one labeled "Data In" (from your switch) and one "PoE" (to your powered device). Setup is straightforward — connect your switch to Data In, then run a cable from the PoE port to your UniFi device. Supported devices include: U7-Pro / U7-Outdoor / U7-Pro-Max / U7-Pro-Wall / U7-Pro-Outdoor / U7-IW / U7-Lite U6-Enterprise-IW / U6-Enterprise It complies with IEEE 802.3at (PoE+) and delivers up to 30W of power, enough to drive power-hungry access points like the U7-Pro series. Note that this is an injector, not a PoE switch — it adds PoE capability to a non-PoE switch without replacing the switch itself.

Product Info

Released in late 2025, the adapter is priced around ¥6,596 on Japan. It comes with a manufacturer warranty and includes only the adapter unit itself — you will need to supply your own Ethernet cables. Market positioning is mid-range. As a 2.5GbE PoE+ injector, it faces few direct competitors, and its tight integration with the UniFi ecosystem is a major selling point. Built-in surge and clamp protection add reliability against power fluctuations.

Best Use Cases

Home users deploying UniFi access points: If you want to use a U7-Pro or U6-Enterprise-IW but don't own a PoE switch, this injector is a cost-effective way to add PoE without upgrading your entire network infrastructure. Small office or retail network admins: Keep your existing gigabit switch and add a 2.5GbE-capable AP without rewiring. The injector sits neatly near the AP or in a wiring closet. * Users needing one extra PoE port: When your PoE switch has no free ports but you need to add just one more AP, this injector fills the gap without buying a new switch. If you already own a multi-gigabit PoE+ switch (e.g., UniFi Switch Pro series), this adapter is redundant. Also, for low-power APs like the U6 Lite, a cheaper 1GbE injector will suffice.

Things to Consider

This is a pure PoE injector — it does not offer VLAN tagging, port management, or any switch-like features. If you need network management, invest in a proper PoE switch. To achieve 2.5GbE speeds, your upstream switch must also support 2.5GbE. If connected to a 1GbE switch, the link will fall back to 1Gbps. The operating temperature range is 32–40°C (90–104°F), which is relatively narrow. Avoid installing it in direct sunlight or unventilated enclosures. It is not weatherproof, so indoor use only. ## FAQ
Q: Can I use this adapter with a U6-Lite? A: Yes, but it's overkill. The U6-Lite draws less power and works fine with a standard 1GbE PoE injector at a lower cost. Q: What Ethernet cable do I need for 2.5GbE? A: Category 5e or higher will work, but Cat6 or better is recommended for reliable multi-gigabit performance. Q: Can I daisy-chain two of these adapters for redundant power? A: No. This adapter is designed for single-device power delivery only and does not support redundant or parallel configurations.
