Kasa EP25 for flexibility, Amazon plug for Alexa-only homes
We rank the Kasa EP25 ahead of the Amazon Smart Plug. The EP25 lists compatibility with Alexa, Google Assistant, Samsung SmartThings, and Siri, shows real-time and historical power use in the Kasa app, and a four-pack was listed at $35.99 on Amazon, about $9 per plug. Engadget's February 2026 guide named it best overall. The Amazon Smart Plug does one thing well: it pairs with Alexa in minutes with no extra app, and Engadget picked it as best for Alexa homes. But Amazon states it works exclusively with Alexa, it has no energy monitoring, and it lists at $24.99 for a single plug. Neither is listed as a Matter plug, so if Matter matters to you, look at Kasa's KP125M instead.
