Power where you need it: USB Power via Ethernet Cables
With the Ubiquiti INS-3AF-USB converter, every Network cable becomes a power source. Do you want to install an IP Camera under the eaves, mount an info tablet on a wall, or realize an IoT project in the basement, but there's no power outlet in sight? No problem. This adapter uses the Power-over-Ethernet (PoE) technology of your Network switch and converts it into a universal 5V USB port. This way, you power your devices with absolute flexibility and with just a single cable.
The smart solution for Raspberry Pi & IP Cameras
The INS-3AF-USB is the perfect partner for countless projects. Operate a Raspberry Pi stably and reliably without having to worry about a separate Power Supply. Or power a WLAN-based surveillance camera that you need to place in a location without an outlet for optimal reception. With an output power of 10 watts (5V/2A), the adapter provides enough energy for most common USB devices and is an indispensable tool for every tech enthusiast and as professional Ubiquiti Accessories.
Central Management: Restart with a click
A crucial advantage for professionals: If you operate the INS-3AF-USB on a manageable PoE switch, you gain full control. Has a connected device frozen? Instead of reaching for a ladder, you can simply switch the corresponding PoE port off and on again via your switch's software. This remote “power-cycle” restarts the USB device and saves you an enormous amount of time and effort during maintenance – ideal for hard-to-reach installations. This way, you manage your end devices as easily as other PoE Injectors / Power Supplies.
Important note: Pure power adapter, no data transfer
Please note that the INS-3AF-USB is a pure power converter. Its task is to convert 48V PoE into 5V USB voltage. It does not transmit Network data from the RJ45 port to the USB port. A USB-connected device, such as a Raspberry Pi, therefore only receives power and must establish its connection to the Network via WLAN. The adapter is not intended to establish a wired LAN connection via USB.

Frequently Asked Questions (FAQ)
Can I charge my phone with the Ubiquiti INS-3AF-USB?
Yes, the converter provides a stable 5V/2A output via a standard USB-A port and can thus charge modern smartphones, tablets, and other USB devices as if it were a powerful wall charger. This is a great accessory for your Network setup, especially when considering various PoE Injectors / Power Supplies.
Does the INS-3AF-USB also transmit network data via the USB port?
No, absolutely not. The adapter is a pure power converter. It converts PoE voltage to USB voltage. No data transmission occurs between the RJ45 port and the USB port. A connected device must establish its Network connection, for example, via WiFi. This is important for understanding how WiFi Routers or WiFi Access Points integrate into your overall Network.
Do I need a special PoE Switch for this adapter?
You need a PoE Switch that supports the 802.3af standard. The adapter works seamlessly with most 'auto-sensing' 802.3af switches. It may not be compatible with older or passive 24V PoE Injectors / Power Supplies from Ubiquiti Networks. For optimal performance, consider UniFi Switch options.
Can I power a Raspberry Pi with the INS-3AF-USB?
Yes, this is a very popular use case. The adapter provides sufficient power with 5V and 2A (10W) to stably power most Raspberry Pi models (e.g., Pi 3 or Pi 4 under normal load). This is a great solution for various smart home or IoT projects, integrating well with your existing Network and Cabling.
Can I restart the connected USB device via my Network Switch?
Yes, if the adapter is connected to a manageable PoE Switch, you can deactivate and reactivate the PoE port of the Switch via software. This interrupts the Power Supply to the adapter and restarts the connected USB device (power cycle). This feature is common in advanced Ethernet Switch and UniFi Switch models.
Is the adapter suitable for outdoor use?
No, the INS-3AF-USB is designed only for indoor use, with an operating temperature range of 0°C to 40°C and without specific weather protection. For outdoor Network solutions, consider robust Enclosures or specific outdoor WiFi Access Points.
