Kasa Smart Plug Power Strip KP303: Three Smart Outlets, One Strip

The Kasa Smart Plug Power Strip KP303 is a compact surge protector that puts three individually controlled smart outlets and two USB ports on a single strip, with no hub required. It suits renters and desk-bound workers who want app and voice control over a few devices without rewiring anything. This review covers the specifications, what each control group means in practice, and where the strip falls short. Buyers ready to move can check the current price at Amazon.

Features and Specifications

Product: Kasa Smart Plug Power Strip KP303
Type: Surge protector power strip with smart outlets
Smart Outlets: 3, individually controlled
USB Ports: 2
Voice Assistants: Works with Alexa and Google Home
Hub Required: No
Color: White

Each of the three AC outlets is a separate smart switch, so the strip behaves like three smart plugs sharing one body. The two USB ports sit alongside them for phones, earbuds and other low-draw devices. Because no hub is needed, the strip talks directly to the home Wi-Fi network and sets up through the Kasa app.

The surge protector part matters as much as the smart part. A strip that controls devices also has to protect them, and this one is built to sit between the wall outlet and the electronics rather than replace a whole-home protector.

Build and Form Factor

The KP303 is a horizontal strip in white plastic, sized to sit on a desk, behind a TV stand or along a kitchen counter. The outlets are spaced along the top face, which keeps chunky adapters from crowding each other the way they do on a bare wall outlet.

The white finish is neutral enough to disappear on a light-colored desk, though it will show dust and scuffs more than a dark strip would. Buyers who want the strip hidden entirely should plan on a spot with some clearance behind the furniture for the plug and cord.

The compact body is the point: three smart plugs and two USB chargers in one footprint instead of five separate bricks. Buyers with a large entertainment center and a dozen devices will find the strip short on outlets, but that is a capacity question rather than a build flaw.

Trade-off: The strip packs three smart switches into a small body, so buyers with many high-draw appliances will run out of outlets long before they run out of devices.

Power and Surge Protection

The surge protection is the reason to buy a strip rather than three loose smart plugs. A single wall connection feeds the whole strip, so one surge event is handled at one point instead of at three separate plugs. That is a cleaner setup for a desk or TV corner where several electronics share a power source.

The three smart outlets are individually controlled, which means a lamp, a monitor and a speaker can each be switched on its own schedule. The two USB ports are there for charging rather than switching, which suits phones and accessories that stay plugged in.

Buyers should think about what they will actually plug in. A strip of this type is designed for typical home electronics, not for space heaters, air conditioners or other high-draw appliances. Matching the load to the strip is the buyer’s job, and it is the most common way people end up disappointed with any smart strip.

Trade-off: The smart switching is the headline feature, but the strip is still a general-purpose surge protector, and buyers with heavy appliances need a different product entirely.

Smart Control and App Features

The Kasa app is where the strip earns its keep. Each of the three outlets appears as its own device, so schedules, timers and away-mode routines can be set per outlet rather than for the whole strip. A buyer can put a lamp on a sunset schedule while leaving a router or a charger untouched.

Voice control through Alexa and Google Home covers the basic on-off commands, which is the feature most buyers use daily. No hub is required, so setup is a matter of the app, the Wi-Fi network and a few minutes of naming each outlet something memorable.

The limitation is that this is a Wi-Fi strip, not a local-protocol one. When the internet or the router goes down, app and voice control go with it, and the outlets fall back to whatever state they were in. Buyers who want smart control to survive an outage should look at hub-based systems instead.

Trade-off: Cloud-dependent control means the strip is only as reliable as the home network, and a router reboot takes the smart features offline with it.

Who It Suits and Who It Does Not

The KP303 suits desk setups, TV corners, renters and anyone who wants a few devices on schedules without installing smart switches in the wall. It also suits buyers already using the Kasa app, since the strip joins the same account and the same routines as the rest of the lineup.

It does not suit buyers who need many outlets, who want to control high-draw appliances, or who insist on local-only smart control that works without the cloud. Those buyers are better served by a larger strip, a plain surge protector plus separate smart plugs, or a hub-based system.

The two USB ports are a nice extra for a bedside table or a desk, but they are not fast-charging ports in the modern sense. Buyers who need quick charging for a laptop or a large phone should keep a dedicated charger in the mix.

Trade-off: The strip is a good fit for light electronics and app-based routines, but it is not a whole-room power solution, and buyers should size their expectations to three switched outlets.

FAQ

1. Does the Kasa Smart Plug Power Strip KP303 need a hub?
   No. The strip connects directly to the home Wi-Fi network and is set up through the Kasa app, so no separate hub or bridge is required.

2. Are the three outlets controlled separately?
   Yes. Each of the three smart outlets is individually controlled, so schedules, timers and voice commands can be applied to one outlet without affecting the others.

3. Does it work with Alexa and Google Home?
   Yes. The strip works with both Alexa and Google Home, which covers the common voice commands for turning outlets on and off.

4. What are the two USB ports for?
   The USB ports are for charging phones, earbuds and similar low-draw devices. They sit alongside the three smart outlets on the same strip.

5. Can the strip be used for a space heater or air conditioner?
   No. A strip of this type is intended for typical home electronics, and high-draw appliances such as space heaters and air conditioners should be plugged directly into a wall outlet.

6. What happens to the smart features during an internet outage?
   App and voice control depend on the home network, so an outage takes those features offline. The outlets stay in whatever state they were in until the connection returns.

7. Is the strip a surge protector as well as a smart strip?
   Yes. The KP303 is a surge protector with smart outlets, so it protects connected electronics while also offering app and voice control.

8. Can the strip be used in a rental apartment?
   Yes. It plugs into a standard wall outlet and requires no wiring or installation, which makes it a practical option for renters who cannot change wall switches.

9. Does the strip work with the Kasa app alongside other Kasa devices?
   Yes. The strip joins the same Kasa account as other Kasa smart plugs and switches, so routines and schedules can be shared across devices.

10. Is the strip suitable for a desk setup with a monitor and lamp?
    Yes. A monitor, a lamp and a speaker are the kind of light electronics the strip is built for, and each outlet can be scheduled on its own.

Bottom Line

The Kasa Smart Plug Power Strip KP303 is the right buy for anyone who wants three app-controlled outlets and a couple of USB chargers in one compact, hub-free strip. It fits desks, TV corners and rentals well, and the per-outlet control is the feature that justifies the price tier. Buyers with heavy appliances or a need for local-only control should look elsewhere, but for light electronics and voice routines, this is a straightforward pick.
