The best powerline adapters are designed to help expand your home network and improve wireless coverage across the home. After reviewing and comparing a range of devices for speed, passthrough, and more, these are our top picks.
We've reviewed a host of networking solutions, including the best Wi-Fi router and best mesh Wi-Fi systems. But powerline adapters offer a slightly different way to expand connectivity, plugging into the mains and then connecting devices to them via an Ethernet cable. In other words, they're the ideal pick if you don't want to wired up your house or home office and when even the best Wi-Fi extenders and best Wi-Fi 6 routers struggle to improve signal strength.
After an extensive review period, we still rare the Devolo Magic 2 Wi-Fi 6 as the best powerline adapter for most people thanks to its support for Wi-Fi 6 and the inclusion of two Gigabit Ethernet ports. If you're in the US, we recommend checking out the equally impressive D-Link Powerline Adapter AV2 available from Amazon.
During testing, what we're looking for from each powerline adapter is connection speed, ease of use, and price, including a range of options to suit different budgets and locations. Where a product hasn't received a full TechRadar Pro review, we've compared specifications, spoke to manufacturers, and used our own in-house experts to ensure each device can offer reliable, stable connections and speeds comparable to wired connections.
The best powerline adapter overall
We believe the Devolo Magic 2 Wi-Fi 6 is still the best powerline adapter you can buy today. The Devolo Magic 2 WiFi 6 delivers fast speeds, stable connection, and all the benefits of mesh Wi-Fi technology. These kits aren’t cheap, but the powerline and Wi-Fi connectivity combination will be ideal for homes with thick walls that block the Wi-Fi signal. This adapter's signal is so strong because it combines the "power" of a powerline adapter and a mesh Wi-Fi network in one system, creating a quality connection that offers the best of both worlds. Further, each adapter has two ethernet ports to help with connectivity around the home, office, or another complex, while the average powerline adapter only has one. This expands the wired connectivity options immensely (legitimately, twice as much!), providing even more devices with reliable, wired, ethernet connection. We could easily plug in our main docking station for our laptops and even plug in the other side to a tower PC we have in for testing, granting both the benefit of a wired ethernet connection without needing to rip into our walls in our office.
We can manage everything via the Devolo companion app on our phone, giving us control over both the 2.4GHz and 5.0GHz bands, providing download speeds of 100Mbps with the Ookla speed test and 12.5MB/s for Steam downloads. While this is not the fastest available, it's within the parameters of what we would expect and need for most use cases. As is common in these adapters, the passthrough power outlet ensures that we don't lose an outlet, helping reduce clutter or the need to pull power from another part of the room. Devolo states that this model is great for larger buildings, even those with multiple stories. We tried this across a generously sized three-story home without a problem.

The best powerline adapter for beginners

While it looks similar to the above listing, this isn't the same product as the Devolo Magic 2 Wi-Fi 6. But this older offering still delivers fast speeds and all the benefits of mesh Wi-Fi technology, making it worthy of second place. It’s an excellent jumping-off point for the G.hn standard, bringing noticeable improvements to network speeds.
Much like the previous product, this model also has two ethernet ports on the receiving end of the extended ethernet line, offering the same great connection abilities as the newer and more expensive model above. Where there is a difference from the above model is that there is only on ethernet port on the sending side of the powerline connection. For us, as well as probably most use cases, this is not a problem at all, as we don't have products right by our router that need ethernet. We have them further away, thus the need for the powerline adapter in the first place. And, if we did need to expand and put network-enabled devices right next to our modem and router, we could grab a network switch to help bring more local ports.

The best powerline adapter for speed
The TP-Link AV2000 is awarded the fastest powerline adaptor, with a maximum speed of 2000Mbps. Though, of course, as with all of the best powerline adapters featured on this list, actual speeds will be lower. Still, it offers fantastic speeds, built-in dual-band wireless ac networks, and a pass-through socket, a valuable space saver in socket-shy home offices. While we have not personally been able to test this powerline adapter quite yet, we have conducted extensive research to see that TP-Link can be trusted as a company and that this product is quality. From our research, we have found that this powerline adapter is quite fast and very stable and just as easy to set up as the above product offerings.
In the starter kit, you'll get two adapters, one has a single Ethernet port, which you should use to connect to your modem or router, and the second one has two Ethernet ports for connecting wired devices. Much like mentioned above, if more ports are needed, there is always an option of putting a network switch on either end, expanding the port offering even further and allowing more devices to have faster hardline internet access.
The good news is its plug-and-play setup requires no configuration, and it also comes with a power-saving mode that claims to reduce power consumption by up to 85%.
The best powerline adapter for coverage
Asus may not be the first company that comes to mind when you think about networking devices, but it makes some very good products - such as the Asus 1200Mbps AV2 1200 Wi-Fi Powerline Adapter. While we have not personally tested this adapter yet, we have conducted independent research and feel confident suggesting this as one of the best available.
As the name suggests, this fast powerline adaptor can also broadcast a Wi-Fi network. Unlike other powerline adapters with Wi-Fi, the Asus 1200Mbps AV2 1200 Wi-Fi Powerline Adapter has external antennae, allowing you to angle them for increased coverage. It means the units look slightly ugly compared to some competitors.
Like others on this list of best powerline adapters, the Asus has a plug-and-play installation. There's also added security in encryption that blocks unauthorized devices.

The best powerline adapter on a budget
If you're looking for a nice, cheap, but reliable powerline adaptor, the TP-LINK AV600 is a great choice. It's much less money than many of the adapters on this list, but it still offers plenty of features.
For example, it can broadcast Wi-Fi, and with a Wi-Fi clone button that syncs settings like SSID and password, you can easily extend your existing wireless network. It also features two Ethernet ports and the second adaptor in the set includes a pass-through socket, so you don't lose out on a power socket when using the adaptor.
While the 600Mbps top speed isn't as high as others on this list, it's still enough to transfer big files and stream media around your home. There's also a user-friendly tpPLC mobile app that allows users to control their network easily.
The best powerline adapter for power passthrough
The Devolo dLAN 1200+ WiFi ac is one of the fastest powerline adapters on the market. It can reach speeds of 1.2 gigabits a second - though, as above, you should note that you won't often get those speeds as numerous factors can affect powerline speeds.
Still, this is a very fast powerline adaptor, and it can also broadcast dual-band wireless ac networks, making it a very versatile powerline adaptor. The adaptor also has a pass-through power port, so you won't lose a power socket - plug other devices into the adaptor itself.
It's not the cheapest out there, and the two ethernet ports may not be enough for more serious gamers, but it certainly delivers alongside Devolo's bold slogan that it "cures weak Wi-Fi."
Best powerline adapter: Frequently asked questions
Is a powerline adapter better than a standard Wi-Fi router?
Sometimes, a powerline adapter can be a better solution than a standard Wi-Fi router. If the area needing internet is across a building from the modem or the Wi-Fi signal is being blocked or weakened by barriers, a powerline adapter may be a great solution. Where Wi-Fi creates a wireless signal, powerline adapters extend a wired ethernet connection through the electrical wiring of a building, allowing for ethernet connections to be sent all around a building without running more cabling.
Does a powerline adapter slow down Wi-Fi?
Powerline adapters do not slow down wi-fi networks. In fact, they can actually speed up your overall network speeds by reducing the strain and freeing up network bandwidth for your router. Granted, if the device that you are choosing to connect by way of powerline adapter is not a heavy usage device, you may not notice a difference at all.
What if I need more ethernet ports than what the powerline adapter has built-in?
At either end of the powerline adapter, you can add a network switch that will expand the port offering by however many ports said network switch has. This will allow your receiving end of the powerline connection to turn one port into enough to run your entire office, for example. For suggestions on which switch to get, check out our guide to the best network switches.
How to choose the best powerline adapters for you
The best powerline adapters provide a simple way of extending the reach of your home network, and as such, there are several factors you ought to consider before you make your choice.
Firstly, consider your typical use at home. Do you use the Internet to access emails and read the occasional web page? Do you use streaming services like Netflix or Disney+? Or are you a serious gamer who requires top connection speeds to ensure you aren’t losing connectivity while engrossed in your games?
Once you’ve analyzed the connectivity and speeds you require, you’ll know whether you’re simply looking for a stronger Wi-Fi connection or prefer the increased reliability of being plugged in via an ethernet cable.
But speed isn’t the only consideration. Not all of these powerline adapters featured are the most intuitive to install, so if you’re unfamiliar with the subject, you’ll likely want to prioritize a plug-and-play option. Finally, these powerline adapters can vary significantly in price, so make sure you know your budget and tailor your choices accordingly.
How we test the best powerline adapters
In compiling this list of the best powerline adapters of 2025, we've tested several key elements on each adapter.
First off, we've road-tested the speeds of each. And while you should know that stated top speeds are rarely achieved in real life - due to the many outside factors that can affect connectivity - they'll still provide a good barometer for which adapters achieve the highest speeds.
Next, we've looked at each adapter's connectivity options, listing the number of ports supplied and additional useful features like Wi-Fi and Wi-Fi cloning.
We've also looked at ease of installation, with some devices leading the way in terms of plug-and-play simplicity versus those requiring a little more thinking time on the user's part. Finally, we've considered the cost of each device, from the initial outlay to the costs involved in any potential future network expansions.
