How We Researched
We analyzed the spec sheets of over 20 current smart plugs, comparing wireless protocols (Wi-Fi, Thread, Matter), physical dimensions to ensure they don’t block adjacent outlets, and the accuracy of their built-in energy monitoring tools. We also aggregated verified buyer feedback regarding connectivity drops.

FAQ
Can I plug a space heater or AC into a smart plug?
You must check the maximum amperage rating of the smart plug. Most standard smart plugs are rated for 15 amps (approx 1800W). High-draw appliances like space heaters or window AC units can exceed this, risking fire or melting the plug. Always verify the appliance’s wattage first.
Do smart plugs work if the Wi-Fi goes down?
If your smart plug uses standard Wi-Fi, you will lose app and voice control during an internet outage. However, physical buttons on the plug will still work, and local protocols like Thread or Zigbee (used with a local hub) can maintain automation without the internet.
Final Thoughts
Smart plugs offer massive convenience for very little money. If you are just starting out, prioritize a plug that supports the new Matter standard to ensure it works with whatever smart speaker you buy in the future. Which appliance are you planning to automate first?
