What a Smart Plug Actually Does
A smart plug sits between your wall outlet and any device. You control power from your phone or by voice. Schedule lamps to turn on at sunset. Kill power to the coffee maker you left on. Randomize lights when you're on vacation.
All four picks work with Alexa and Google Assistant. The EP25 adds HomeKit and SmartThings for cross-platform homes.
Comparison Table
Detailed Breakdown
1. TP-Link Kasa EP25 ($12.50/plug) — The Feature King
The EP25 does everything: real-time energy monitoring (watts and kWh with 7/30-day history), Away Mode that randomly turns devices on/off to simulate occupancy, sunrise/sunset scheduling, and compatibility with all four major smart home platforms. Wirecutter's top pick, PCMag Editors' Choice.
"I use the energy monitoring to track exactly how much my space heater costs to run. Turns out it's $38/month in winter. Scheduling the heater to only run when the electricity rate is low saved me $15/month. The app is fast and the schedules actually work offline — they're stored on the plug, not in the cloud." — Amazon verified purchase review, 4.5★

2. Amazon Smart Plug ($19.99) — Zero Setup
571,000 reviews at 4.7 stars. The setup is the selling point: plug it in, open the Alexa app, it's discovered automatically. No third-party app, no account creation, no WiFi password entry. Compact design leaves the second outlet free.
The trade-off: Alexa-only. No Google Home, no HomeKit. No energy monitoring. You're buying simplicity, not features.
"My 70-year-old mom set this up herself. That's the review. If she can do it without calling me, it's foolproof. Works every time with Alexa routines — lamp comes on at sunset, goes off at bedtime. Never had a disconnection in 2 years." — Amazon verified purchase review, 4.7★

3. Kasa EP10 ($6.37/plug) — Tiny, Cheap, Reliable
The EP10 is the EP25 minus energy monitoring and HomeKit, at half the price. Ultra-compact — the smallest in Kasa's lineup, fits in tight outlets behind furniture. Run-time tracking, Away Mode, scheduling, and Alexa/Google/IFTTT support.
"Smallest smart plug I've found. Fits behind my bookshelf without pushing it away from the wall. Works flawlessly with Google Home routines. No energy monitoring but at $6 a plug I'll live without it. Bought 8 of these over 2 years, zero failures." — Amazon verified purchase review, 4.5★

4. Govee 4-Pack ($25.49 total) — Best Value Per Plug
At $6.37 per plug, the Govee matches the EP10 on price but adds Bluetooth for more reliable pairing. Works with Alexa and Google Assistant. ETL and FCC certified.
The trade-off: Govee's app isn't as polished as Kasa's. No Away Mode, no energy monitoring. Basic on/off scheduling only.
"Bought these for Christmas lights and never took them down — now they control my coffee maker, living room lamp, and fan. Bluetooth pairing made setup smoother than WiFi-only plugs. App is fine, not fancy. For the price of one fancy plug I got four that just work." — Amazon verified purchase review, 4.5★
