Kasa Smart Plug HS103P4 4-Pack Review 2026: The Easiest Smart Home Upgrade

The Kasa Smart Plug HS103P4 four-pack is the classic starter smart home purchase: four Wi-Fi outlets that add voice control, remote control, and scheduling to any lamp, fan, or appliance — no hub required. Ranked #6 in Electrical Outlet Switches on Amazon, it is one of the best-selling smart home products for good reason.

Smart plugs are the gateway drug of home automation, and the HS103P4 is the ideal first hit. Setup takes minutes per plug in the Kasa app, Alexa and Google Assistant control works out of the box, and schedules automate lamps and holiday lights effortlessly. At roughly the price of a pizza per plug in the four-pack, the value is undeniable.

Bottom line: Four Wi-Fi smart plugs with voice control, remote access, and scheduling — no hub needed. The perfect first smart home purchase; superb value in the 4-pack.

Key features that stand out

Voice control via Alexa and Google Assistant. Turn lamps, fans, and appliances on and off hands-free with simple voice commands.

Remote control from anywhere. The Kasa app lets you check and control plugs from the office, on vacation, or from the couch.

Schedules and timers. Automate lamps to turn on at dusk, run holiday lights on a timer, or shut off the iron on a countdown — all from the app.

No hub required. Each plug connects directly to your 2.4GHz Wi-Fi network. No extra hardware to buy or maintain.

15A UL certified. Rated for 15 amps and UL certified for safety, handling most household lamps and small appliances.

Who it’s for

The HS103P4 four-pack is ideal for smart home beginners who want maximum impact for minimum money. It suits renters (no wiring changes), frequent travelers (remote control and away-mode scheduling simulate occupancy), and anyone with hard-to-reach lamps or holiday lighting to automate.

What to watch out for

The plugs require 2.4GHz Wi-Fi — they will not connect to 5GHz-only networks, so check your router settings during setup. They are on/off only, with no energy monitoring or dimming. And while the design is compact, very tight outlet spacing may still block the adjacent socket.
