Kasa HS103P2 vs Amazon Smart Plug (2026)
Kasa HS103P2 vs Amazon Smart Plug compared: the cheapest plug against the simplest Alexa setup, and which one you should buy.
#2 in our rankings · Best budget
Kasa Smart Smart Plug Mini HS103P2
Best for: Buyers who want to smarten up two lamps or fans for the least money, in an Alexa or Google household.
#3 in our rankings · Best for Alexa-only homes
Amazon Smart Plug
Best for: Alexa households who want the easiest setup of any plug here, with no second app to learn.
Our recommendation
Buy the Kasa HS103P2 if you want the lowest cost, a two-pack, and support for Google as well as Alexa. Buy the Amazon Smart Plug if the household runs on Alexa only and you want the simplest setup, with no second app to learn. Both switch a lamp on and off just as well, so the choice is flexibility and cost against setup simplicity.
Platforms: two assistants against one
The HS103P2 works with Alexa and Google Assistant, plus IFTTT, so it survives a move between the two big voice platforms. The Amazon Smart Plug works with Alexa only, which is fine in an Alexa household and a dead end anywhere else. If there is any chance the household adds a Google device later, the Kasa plug is the safer buy.
Pack size and cost
The HS103P2 comes as a two-pack, so one purchase covers two lamps or a lamp and a fan, and the cost per plug is the lowest in this list. The Amazon Smart Plug is sold singly, so covering two lamps needs two purchases. For a household starting from scratch, the Kasa two-pack is the better value.
Setup and the app
The Amazon Smart Plug sets up inside the Alexa app with no second account, which is the simplest setup here. The HS103P2 needs the Kasa app and its own account first, then links to Alexa or Google. That extra step is small, but it is the real difference for a first-time buyer or a gift.

- Your household runs on Alexa only
- You want the simplest possible setup with no second app

Strengths and limitations
Kasa Smart Smart Plug Mini HS103P2
Strengths
- The compact body leaves the second socket on a duplex outlet free, so one outlet can hold two of these plugs stacked.
- Setup is quick through the Kasa app, with schedules, timers, and away mode that switches lights on and off while you are out.
- It answers to Alexa and Google Assistant with no hub, so there is nothing extra to buy or plug in.
Limitations
- There is no energy monitoring, so it cannot report what a connected appliance uses or costs to run.
- It works on 2.4GHz Wi-Fi only, so a router that only broadcasts 5GHz needs its 2.4GHz band switched on.
- Apple Home is not supported, so iPhone-first households should look at the EP25 or the KP125M instead.
Amazon Smart Plug
Strengths
- Setup is the simplest here: the Alexa app finds the plug on its own, with no separate account or second app needed.
- Routines in the Alexa app can switch the plug with other Echo devices, so a single voice command can run a whole room.
- The slim body sits low on the outlet and suits lamps, fans, and coffee makers with a physical on and off switch.
Limitations
- It works with Alexa only, so it is a dead end if the household later moves to Google or Apple.
- There is no energy monitoring, so it cannot track what a connected appliance uses.
- It works on 2.4GHz Wi-Fi only and is for indoor use only, so it cannot cover the garden or a 5GHz-only network.

Questions, answered
Do they work with the same lamps?
Yes. Both are rated at 15A and suit lamps, fans, and coffee makers with a physical on and off switch. Neither offers energy monitoring or dimming.
Can I mix both plugs in one home?
Yes, if the household uses Alexa. Both plugs appear in the Alexa app and can join the same routines, though they need their own apps for setup. Mixing makes less sense if the household also uses Google, since the Amazon plug cannot join Google Home.
Which is better for schedules?
Both support schedules and timers, and both can run them through the Alexa app. The Kasa plug also offers away mode in the Kasa app, which switches lights randomly while you are out.
