Description
48V Passive PoE Gigabit Adapter for TP-Link Passive PoE Devices
The TP-Link TL-POE4818G is a 48V passive PoE Gigabit adapter that simultaneously delivers power and data to compatible passive PoE devices over a single Ethernet cable — eliminating the need for a separate power outlet at the device location. With Gigabit speed support, plug-and-play operation, and a wall-mountable design, it's a clean, simple solution for powering TP-Link passive PoE access points, IP cameras, and other compatible devices in homes and small business installations across Australia.
Important: The TL-POE4818G uses passive PoE (48V), which is not compatible with IEEE 802.3af/at standard PoE devices. It is designed specifically for use with TP-Link passive PoE products. Using it with non-compatible devices may cause damage.
Key Features
-
48V Passive PoE: Delivers 48V passive PoE power and Gigabit data over a single Cat5e or above Ethernet cable to compatible TP-Link passive PoE devices.
-
Gigabit Speed Support: Full 10/100/1000Mbps throughput — no speed reduction when powering devices via PoE.
-
Plug & Play: No configuration, software, or management interface required — connect and go.
-
Auto Power Detection: Automatically determines the necessary power requirements of the connected device.
-
Wall-Mountable Design: Includes wall-mounting brackets for clean, permanent installation on a wall or surface — no loose adapter sitting on a desk or floor.
-
Compact Form Factor: Small and unobtrusive — suitable for discreet installation in offices, retail stores, and home environments.
Common Use Cases
- Powering TP-Link passive PoE wireless access points (e.g. EAP series with passive PoE support) where a PoE switch is not available
- Adding a single passive PoE device to an existing non-PoE network without replacing the switch
- Clean wall-mounted installation in offices, retail stores, and home environments
- Powering TP-Link outdoor access points and CPE devices that require 48V passive PoE

Frequently Asked Questions
What is passive PoE and how is it different from standard PoE (802.3af/at)?
Standard PoE (IEEE 802.3af/at) uses a negotiation process to detect compatible devices before applying power, making it safe to use with any 802.3af/at-compliant device. Passive PoE applies voltage directly to the Ethernet cable without negotiation — it is simpler and lower cost, but only safe to use with devices specifically designed for passive PoE at the correct voltage. Using a passive PoE adapter with an incompatible device can cause damage. The TL-POE4818G is designed for use with TP-Link passive PoE products only.
Which TP-Link devices are compatible with the TL-POE4818G?
The TL-POE4818G is recommended for TP-Link passive PoE products including certain EAP access points, CPE outdoor units, and other TP-Link devices that specify 48V passive PoE input. Check your device's specifications to confirm it requires 48V passive PoE before purchasing. Refer to the datasheet for the full compatible device list.
Can I use this with a standard 802.3af/at PoE switch?
No. The TL-POE4818G is a passive PoE injector — it connects between your non-PoE switch/router and the powered device. It is not designed to be used in conjunction with an active 802.3af/at PoE switch port. Connect the LAN port of the adapter to your switch, and the PoE port to your passive PoE device.
Does it reduce network speed?
No. The TL-POE4818G supports full Gigabit (10/100/1000Mbps) throughput — there is no speed reduction when powering devices via passive PoE.
Can I mount it on a wall?
Yes. The TL-POE4818G includes wall-mounting brackets for a clean, permanent installation. This is particularly useful when the adapter is installed near a ceiling-mounted access point or in a location where a loose adapter would be impractical.
