Rock Space AC1200 WiFi Extender review: Features If it’s on for 24 hours a day, the device will have an estimated $4.90 in yearly electricity costs if you pay the national average of 13 cents per kilowatt-hour. The Rock Space Wi-Fi range extender used 4.3-watts of electricity.
This makes it ideal for multi-floor use, like in a townhouse. It delivered 112.1Mbps, right behind the Netgear EX2800’s 124.4Mbps. The Rock Space extender partially redeemed itself when I set it up a floor above the router and placed the test machine 40-feet away. That’s well off the Netgear EAX20’s 124.4Mbps pace. With it set up on the same floor 40-feet from the host router, the Rock Space extender delivered 50.0Mbps to a test machine 50-feet farther away.
