TP-Link AV600 Powerline Ethernet Adapter Kit (TL-PA4010 KIT)
Standard: AV600
Ports: 100 Mbps Ethernet
Form Factor: Nano sized
Pairing: Plug Pair & Play
Power Feature: Power saving mode
Best For: Budget wired connections
The AV600 kit is the plainest entry in the range: two nano adapters, a plug-and-play pairing routine and a power saving mode that idles the units when traffic drops. The 100 Mbps port is the telling detail — this is a kit for a single device that does not need much bandwidth, such as a smart TV streaming in standard definition or a desktop used for browsing. The tiny housing means it will not block a neighbouring socket on a double outlet, which matters in a house where extension leads are already crowded. It is the sensible first step for a buyer testing whether powerline works at all in an old wiring setup.
This pick earns its place on price alone. It suits renters, students and anyone wiring up a spare room on a tight budget, and it is painless to move between sockets while testing which outlet gives the cleanest link.
Trade-off: The 100 Mbps port caps the connection well below what a modern fibre plan can deliver, so it is a poor fit for a household that expects full-speed downloads or heavy 4K streaming.
TP-Link AV1000 Powerline Ethernet Adapter KIT (TL-PA7017 KIT)
Standard: AV1000
Ports: Gigabit Ethernet
Form Factor: Nano sized
Pairing: Plug Pair & Play
Power Feature: Power saving mode
Best For: Everyday wired networking
The AV1000 kit steps the port up to Gigabit while keeping the same small shell and the same two-button pairing. That combination is the sweet spot for most homes: the gigabit port will not bottleneck a typical broadband line, and the compact body leaves the second socket free for the extension lead that everything else is plugged into. Power saving mode is included, so the adapters draw less when nothing is moving across the link. Setup is a case of plugging both units in and pressing pair on each, with no app or configuration screen required.
This is the pick for a household that wants one reliable wired point — a games console, a work laptop, a TV box — without paying for features it will never use. It suits buyers who already have decent Wi-Fi and only need to fix one stubborn room.
Trade-off: There is no passthrough socket and no Wi-Fi, so the adapter itself occupies an outlet and does nothing for wireless dead zones elsewhere in the house.
TP-Link AV2000 Powerline Ethernet Adapter (TL-PA9020P KIT)
Standard: AV2000
Ports: 2x Gigabit Ethernet
Technology: 2×2 MIMO
Passthrough: Yes
Pairing: Plug Pair & Play
Power Feature: Power saving mode
Best For: High-bandwidth wired links
The AV2000 pair is the fastest wired option here, and the passthrough socket is the feature that matters most in a house full of extension leads. Rather than consuming an outlet, the adapter passes power through, so a strip or a lamp can still be plugged in on top. Two Gigabit ports mean a console and a desktop can share one adapter, and 2×2 MIMO uses more of the electrical wiring to carry data in both directions. It is the model to choose when the run between router and destination is long and the wiring is not new.
This suits gamers, home workers moving large files and anyone who has already tried a slower kit and found it wanting. It is the premium wired pick, and the price reflects the extra port and the passthrough hardware.
Trade-off: The larger passthrough body is bulkier than the nano models and can crowd a shallow wall box, and the extra speed only pays off if the home’s wiring and broadband plan can support it.
TP-Link AV1000 Powerline Ethernet Adapter WiFi Extender Kit (TL-WPA7617 KIT)
Standard: AV1000
Wi-Fi: AC1200 dual band
Ports: Gigabit Ethernet
Passthrough: Yes
Mesh: OneMesh compatible
Pairing: Plug Pair & Play
Best For: Wired and wireless coverage together
This kit pairs an AV1000 adapter with an AC1200 dual-band extender, so the far end of the link offers both a Gigabit socket and a Wi-Fi signal. The passthrough design keeps the wall outlet usable, and OneMesh compatibility lets the extender work alongside a compatible TP-Link router as a single network name. For a house with extension leads running along the skirting boards, that means the extender can be placed where the power actually is rather than where the Wi-Fi needs to be. Pairing stays plug and play.
It is the right pick for a buyer who wants to solve a dead zone and a wired device at the same time, without buying two separate products. It suits families with phones, tablets and a TV all competing for signal in the same back room.
Trade-off: The Wi-Fi side is AC1200 rather than the newer Wi-Fi 6 standard, so devices that support Wi-Fi 6 will fall back to older speeds on this extender.
TP-Link AV1000 Powerline + AX1500 Wi-Fi 6 Extender KIT (TL-WPA7817 KIT)
Standard: AV1000
Wi-Fi: AX1500 dual band Wi-Fi 6
Ports: Gigabit Ethernet
Mesh: EasyMesh compatible
Pairing: Plug Pair & Play
Best For: Modern devices in weak signal areas
The newest kit in the group combines an AV1000 powerline adapter with an AX1500 dual-band Wi-Fi 6 extender. Wi-Fi 6 brings better handling of many devices at once, which is exactly the problem in a busy household where everything connects in the same corner of the house. EasyMesh compatibility allows the extender to join a mesh setup rather than sitting as a separate network, and the Gigabit port gives a wired option at the far end. Plug and play pairing keeps installation simple.
This is the pick for buyers with recent phones, laptops and consoles that can actually use Wi-Fi 6, and for anyone building a mesh network around a powerline backbone. It costs more, but it is the most future-facing option here.
Trade-off: The Wi-Fi 6 benefit only applies to devices that support it, and older hardware will see no improvement over the cheaper AC1200 kit.
Before You Buy
- Wiring age: Powerline performance depends on the electrical circuit, so a very old or heavily branched ring main may deliver less than the box suggests.
- Extension leads: A strip plugged into the adapter is fine for power, but the adapter itself should go straight into a wall socket wherever possible.
- Passthrough: A passthrough model preserves the outlet, which matters in rooms where every socket is already in use.
- Port speed: A 100 Mbps port limits the link regardless of the AV rating, so match the port to the broadband plan.
- Wi-Fi standard: AC1200 suits most devices; Wi-Fi 6 is worth the extra only if the household owns compatible hardware.
- Mesh compatibility: OneMesh and EasyMesh only work with compatible routers, so check the existing router before relying on it.
- Pairing: All five kits pair with a button press, but mixed brands will not talk to each other.
Frequently Asked Questions
-
Does a powerline adapter work through an extension lead?
It can, but performance drops. The adapter should plug into a wall socket, with the extension lead used for other devices rather than between the adapter and the wall. -
Which kit is best for a house with old wiring?
The AV2000 passthrough kit is the strongest wired choice, but no powerline adapter can guarantee speed on aged wiring. Buying a cheaper kit first to test the circuit is a reasonable approach. -
Is AV2000 twice as fast as AV1000?
No. The AV figures are theoretical maximums for the powerline link, and real throughput depends on wiring, distance and interference between sockets. -
Can a powerline kit replace a Wi-Fi extender?
Only the two Wi-Fi kits here can. The wired-only models add an Ethernet point and do nothing for wireless coverage. -
Do all five kits work with the same router?
Yes, each connects to a router by Ethernet cable. Mesh features are the exception, since OneMesh and EasyMesh need a compatible TP-Link router. -
Is passthrough worth paying for?
In a house where sockets are scarce, yes. It keeps the outlet usable and avoids adding another extension lead to the chain.
Bottom Line
For most homes dealing with extension leads and awkward socket placement, the TP-Link AV1000 Powerline Ethernet Adapter KIT (TL-PA7017 KIT) is the best powerline adapter for a house with extension leads: a Gigabit port, a nano body that leaves the second socket free, and a price that sits comfortably in the middle of the range. Buyers who need Wi-Fi at the far end should step up to the AV1000 Wi-Fi Extender Kit, and anyone chasing maximum wired speed through a crowded outlet should choose the AV2000 passthrough pair.
