The Best Power Supply Network Adapters of 2026
Top choice
This set adds fast two-wire network connectivity wherever you have power in your home.
If your Wi-Fi can’t reach one or two devices, such as game consoles or streaming boxes, and you can’t use Ethernet cables in your home (or don’t want to), the TP-Link TL-PA9020P KIT is one of the best ways to extend your network to places where Wi-Fi is spotty. It ranks among the top three fastest competitors in our download and browsing tests, so you can be sure you get a fast wired connection in the room where you put the adapter whether it’s your router or your home’s architecture.
This power line adapter was faster than Wi-Fi, especially at close range. At a distance of 25 feet, throughput jumped from 78 Mbps on Wi-Fi to 238 Mbps, a 205% improvement. That speed boost really makes a difference when you’re downloading large files like PC game updates. When we increased the distance in our tests, the TL-PA9020P KIT’s connection was still 76% faster than Wi-Fi in the same area.
It’s a good price. In addition to performance, the TL-PA9020P KIT costs $10 to $20 less than our runner-up, the Netgear PLP2000. Both kits have two Ethernet ports on each adapter, and both offer the same performance and power pass-through ports, allowing you to use the power output for other devices.
Very easy to set up. Just plug in the TL-PA9020P KIT adapters, and they work out of the box. If you live in a multi-unit environment, such as a building, you have to take the extra step of enabling 128-bit AES security by pressing the sync button on each adapter, but it’s a one-time process that takes seconds to implement.
A longer warranty is a plus. Like the other TP-Link and Zyxel adapters we tested, the TL-PA9020P KIT comes with a two-year warranty, twice as long as the one-year coverage on the D-Link and Netgear adapters we tested. Only the TrendNet TPL-423E2K comes with a three-year warranty, but that model has other issues.
Two Ethernet ports keep your devices from hijacking your Wi-Fi. Your set-top box, smart TV, gaming PC, and any other devices in the area will benefit from a strong wired connection signal, and all your devices, like your phones, should be as responsive as they will be on a less congested wireless network.
Cables are best for sensitive applications. During our long-term testing of the TP-Link TL-PA9020P KIT and Netgear PLP2000, we found that Internet gaming latency, aka lag, is shorter on wired power adapters than on the Wi-Fi 6 signal we have in our test home. Our esports expert switches to the powerline of A hero again Counter-Strike 2 gaming sessions, even though he has a strong Wi-Fi signal in his room.
Flaws but not dealbreakers
A shiny box. Plugged into the bottom outlet, each TL-PA9020P KIT adapter covers the floor plug of the power outlet above it; you may be able to plug a two-prong plug into the surface, but most three-prong plugs won’t fit. Thankfully, each adapter has a pass-through adapter on the front, so you can connect the device to the adapter itself.
It doesn’t have built-in Wi-Fi. You need to connect a wired access point or Wi-Fi extender to the TL-PA9020P KIT if you want a wireless network for a long distance connection. Even with the added complexity, however, the result is likely to be a faster system than you can find on Wi-Fi-capable TP-Link TLA-WPA8631P KIT or TL-WPA7617 KIT—the TL-PA9020P KIT aced both adapters in our speed test.
