SMUGDESK Active PoE Splitter USB-C 5V 802.3af

SKU CH-JSE7-4DB3J

Converts IEEE 802.3af PoE input to 5V USB-C power for Raspberry Pi 4, cameras and USB-C devices with built-in protection

  • Converts PoE to stable 5V USB-C power
  • IEEE 802.3af compliant input for standard PoE networks
  • Built-in overvoltage, overcurrent and short-circuit protection
  • Compact design fits inside enclosures and cabinets
  • Plug-and-play with PoE switch or injector

Active PoE Splitter for USB-C Devices

This active PoE splitter converts IEEE 802.3af power over Ethernet into a stable 5V USB-C output. It is designed for Raspberry Pi 4, Google WiFi units, security cameras and other USB-C powered gadgets. The adapter removes the need for separate mains adapters by drawing power from existing PoE network infrastructure. Ideal for smart home, remote monitoring and edge computing deployments.

Plug-and-Play Installation with Protection

Connect a PoE Ethernet cable from a compliant switch or injector to the input and your USB-C device to the output; no configuration is required. The compact form factor fits easily inside enclosures and network cabinets. Integrated overvoltage, overcurrent, short-circuit and thermal protection circuits guard connected hardware against unstable supply. Verify that the source equipment follows the 802.3af standard before connecting.

5V USB-C Output Within 802.3af Limits

The splitter delivers 5V power suitable for single-board computers, wireless access points and IP cameras that operate within the IEEE 802.3af power budget. It cannot support devices requiring higher voltages or power levels beyond the standard af classification. PoE+ (802.3at) and passive PoE sources are not compatible and will not function with this unit.

Questions about this item

How can I confirm the splitter is delivering 5 V to my Raspberry Pi 4 after plugging it in?

The USB-C port will supply a steady 5 V output once a live 802.3af PoE link is detected; the Pi 4 boots normally and its power LED stays solid, showing the converter is active.

What comes in the box and do I need any extra cables or injectors?

The package contains the splitter unit only; you must provide a standard Ethernet cable from an 802.3af PoE switch or injector and a USB-C cable to reach your device.

Which PoE standard should my switch or injector support for this model to work?

This unit requires an IEEE 802.3af PoE source; 802.3at or passive PoE equipment will not power it correctly.
