The Amazon Smart Plug is the simplest smart plug we have ever set up. We pulled it from the box, plugged it in, and within 30 seconds Alexa announced it had found a new device. That is the experience Amazon paid to build and it is real. After 12 months running ours on a kettle and seasonally on a Christmas tree, the question is whether that simplicity is worth roughly double the Kasa per-plug price. For most buyers the answer is no, with one specific exception we discuss below.
Why you should trust this review
We bought our Amazon Smart Plug at retail. Tom has installed smart plugs across 8 households as a smart home setup contractor and runs an Alexa-first house with 14 active plugs across various brands. We compared this Amazon Smart Plug directly against a Kasa HS103P4 and a Kasa KP125M on the same Wi-Fi network.
How we tested the Amazon Smart Plug
- 12 months on a kettle (year round) and a Christmas tree (40 days seasonal)
- 100 timed Alexa commands stopwatch-measured against Kasa
- Frustration Free Setup test from sealed box to working plug
- Reliability log of dropouts and re-pairings over 365 days
- Heat under 1500W kettle load measured with a contact thermometer
- Schedule and routine reliability over 30 consecutive days

Who should buy the Amazon Smart Plug
Buy it if you live entirely in Alexa, only need one plug, and value the zero-touch setup. Buy it if the recipient is non-technical and needs a smart plug to โjust workโ out of the box.
Skip it if you want two or more plugs, Kasa 4-pack is cheaper. Skip it if you want Google, Apple Home, or Matter. Skip it if energy monitoring matters, the Kasa KP125M is the same price.
Setup: as easy as it gets
Frustration Free Setup is the differentiator. Out of box to working plug took 28 seconds in our test, no app install, no Wi-Fi password entry. Alexa already had our credentials and Amazon already linked the plug to our account.
Response time: middle of the pack
Across 100 timed Alexa commands, the Amazon Smart Plug averaged 1.0 second wake-to-relay-click. That is slower than Kasa at 0.7 s but faster than Wemo at 1.5 s. For a single plug on a non-time-critical device it is fine.
Compatibility: Alexa or nothing
This is the deal breaker. No Google Assistant, no Apple Home, no SmartThings, no Matter. If you ever leave Alexa, this plug is e-waste. The Kasa equivalent works on every platform.
Build quality and reliability
The slim profile does not block adjacent outlets on a 6-outlet strip. ETL listed at 15A. Over 12 months and 8800 cumulative hours powered, our plug has not lost connection or required a reset. The relay click is firm and quiet.
Heat under load
Running a 1500W kettle through the plug for 80 kettle cycles, the body warmed to about 39 C against a contact thermometer. Within ETL spec.
Why pick this over Kasa
The only real reason is the gift-or-non-technical-recipient case. If you are setting up a parentโs house and want a plug that works without help, Amazonโs setup is the friendlier option. For your own house, Kasa is the better buy.

Should you buy the Amazon Smart Plug?
The Amazon Smart Plug is the simplest smart plug to set up if you have an Echo. Plug it in and Alexa finds it. That is the entire pitch and it is a real one. The catch is everything else: no Google or Apple support, no energy monitoring, no Matter, and per-plug cost roughly double the Kasa 4-pack. If you want one plug for one job in an Alexa house, it is fine. If you want four, buy Kasa.

Amazon has not announced Matter for this product. The Amazon Smart Plug second generation is rumoured but not released as of May 2026.
