Is the Kasa Smart Plug HS103P4 worth it?
A top pick in Smart Home on Amazon (#14 when we checked, Nov 9, 2026)
Worth it if you want four plug-in outlets that add app control, voice commands, and schedules to lamps, fans, humidifiers, or other compatible electronics without a hub. The 2.4GHz Wi-Fi setup and Alexa and Google Home support make it a practical starting point for a popular smart-home setup.
Good to know: If your home uses a different smart-home platform or only offers a 5GHz Wi-Fi network, look for a plug confirmed to support that setup.
Smart plugs that remove a daily control step
A lamp is on the far side of the room, the fan is running after you leave, and the holiday lights still need switching. The Kasa Smart Plug HS103P4 puts those jobs behind a phone command, voice request, or schedule instead of making you reach for each device.
The key design choice is Wi-Fi control through the Kasa app. Plug the unit in, connect it to a 2.4GHz Wi-Fi network, and follow the app's setup instructions. From there, the listing supports remote on and off control, so you can manage a connected appliance from your smartphone while at home or away. That is the useful change: the outlet becomes a control point you can reach without standing beside it.
Scheduling adds a second layer. Timer and countdown options can turn compatible electronics on or off automatically, while Alexa and Google Assistant add voice control. The four-pack gives you four outlets for separate lamps, fans, humidifiers, or similar devices. Each plug is rated at 15 amps and 1,800 watts, and the listing identifies the unit as UL certified. Check the connected appliance and your network before buying, since this model requires 2.4GHz Wi-Fi and a compatible voice platform.
You get four individually usable smart plugs, app control from anywhere, voice control, and scheduling in one pack. That makes sense if you want to add automation to several existing appliances without replacing them or adding a hub.
Great for
- You want four smart plugs for separate lamps or small home electronics
- You use Alexa or Google Home and want voice control
- You want phone-based control while away from home
- You want timer or countdown schedules for lights, fans, or humidifiers
Maybe not for you if
- You need a plug for a 5GHz-only Wi-Fi network
- You use a voice platform other than Alexa or Google Home
- You need a different outlet format or a device-specific compatibility feature
The Kasa Smart Plug HS103P4 is a good fit for readers who want straightforward control over several lamps, fans, humidifiers, or similar electronics. Its four-pack, Kasa app, remote operation, schedules, and Alexa and Google Home support cover the main reasons to add a smart plug. Setup requires 2.4GHz Wi-Fi, and compatibility should be checked for your network and devices first. If those conditions match your home, this is a sensible way to remove repeated outlet switching from your day.
Amazon shoppers rate it 4.6 out of 5 across 150,831 ratings. That is their number, not ours.
