Powerline and PoE adapters carry a network connection over a building's electrical wiring or an Ethernet cable, for rooms where Wi-Fi is weak and running a cable is impractical. Our range of five models comes from TP-Link, STRONG and Mercusys, and suits homes, flats and small offices.
How to choose a powerline or PoE adapter
Powerline or PoE. A powerline adapter sends data through your mains wiring, so it needs a wall socket at each end. PoE (Power over Ethernet) sends power and data down one network cable to a device such as an access point or camera, so check which method your setup needs before comparing models.
Speed rating. Our range includes adapters rated at 300 Mbit/s and one rated at 1428 Mbit/s. These figures are theoretical maximums, and real-world speeds are lower and depend on the condition of your wiring. The 300 Mbit/s models are enough for browsing and streaming, while the faster one suits 4K video or a busy household.
Ports and Wi-Fi. Some models in our range have three Ethernet ports, which lets you connect a TV, games console and PC through one adapter. The Ethernet ports on these models run at up to Gigabit speed (10/100/1000 Mbit/s). If you also want wireless coverage in the far room, look for a model with built-in Wi-Fi. Some of those list WPA2-PSK security, and one lists WPA3, which is the newest standard.
Plug and wiring. The adapters in our range use a Type E/F plug, the European style, so check that it fits your sockets or that you have a suitable plug adapter. Powerline works best when both adapters are on the same electrical circuit, and a socket directly in the wall usually performs better than a multi-plug extension.
Powerline and PoE brands in our range
- TP-Link: a networking specialist with a long-running powerline line-up, from simple Ethernet adapters to kits that add Wi-Fi in the second room. It supplies most of the models in this category.
- Mercusys: the home networking brand from TP-Link, focused on straightforward, easy-to-set-up devices for everyday home use.
- STRONG: an Austrian brand best known for Wi-Fi repeaters and powerline adapters aimed at home users.
Powerline and PoE adapters: frequently asked questions
What does a powerline adapter do?
A powerline adapter turns your home's electrical wiring into a network cable. You plug one adapter into a socket next to your router and connect it with an Ethernet cable, then plug a second adapter in another room. Any device connected to the second adapter gets a wired connection to your router.
Do I need more than one adapter?
Yes, powerline adapters work in pairs at the very least. One connects to the router and the other sits where you need the connection. Many kits are sold as a pair, and extra adapters can usually be added from the same brand to cover more rooms.
Is powerline better than a Wi-Fi extender?
Powerline is often steadier when thick walls or several floors weaken Wi-Fi, because the signal travels through the wiring instead of the air. A Wi-Fi extender is simpler if you only need coverage and have no wired devices. Models with built-in Wi-Fi combine both approaches.
Can I plug a powerline adapter into an extension lead?
It is possible, but not recommended. Extension leads and surge-protected multi-plugs can filter the signal and noticeably reduce speed. For the best result, plug the adapter directly into a wall socket.
