TP-Link Kasa Smart Power Strip KP303: Smarter Control for Your Home

Picture being able to switch off every light in the living room, turn the fan off and stop the coffee machine with a single voice command - or have it all happen automatically before you go to sleep. That’s exactly what the TP-Link Kasa Smart Power Strip KP303 sets out to do, without fuss and without needing an extra hub.

Three sockets, one power strip, complete control from your phone

The Kasa KP303 is a Wi‑Fi power strip with three independently controlled sockets and two USB ports. Its key advantage is that each socket operates separately: you can power on only the device you want without triggering the others. This is particularly handy in home offices, TV rooms and bedrooms, where several devices share the same wall outlet.

Setup is quick using the Kasa Smart app (iOS and Android). After connecting the strip to your home 2.4 GHz Wi‑Fi, each socket appears individually in the app and can be given a custom name. The whole process takes under five minutes and doesn’t require any additional hardware.

• 3 independent sockets: each outlet is controlled individually in the app, so you don’t have to switch everything on or off at once
• 2 USB ports that stay active: charge a phone or tablet without taking up the smart sockets, with 5V and 2.4A output on each port
• Surge protection: built-in ETL certification helps protect sensitive devices from unexpected voltage spikes
• Works with Alexa and Google Assistant: voice control without needing to pick up your phone, integrated with the main assistants
• Flexible scheduling: set each socket to switch on and off at fixed times or repeat automatically on selected days

The small detail that matters in a connected home

Anyone who uses smart devices at home knows the real challenge is keeping things organised rather than ending up with a mess of adapters and plugs everywhere. The Kasa smart power strip deals with that neatly: one device replaces three separate smart plugs and also frees up space at the wall. If you’re building out a home office or an entertainment setup, the tidier layout alone can justify the purchase.

Away mode is one of the features that stands out most. It turns sockets on and off at random times to mimic someone being at home. It’s a subtle extra layer of security for frequent travellers who want the property to look occupied, without relying on cameras or complicated systems.

Scheduling that works for you while you sleep

Scheduling on the Kasa KP303 goes further than a basic “on at 18:00, off at midnight”. You can create routines with weekly repeats, set countdown timers, and even group sockets across different Kasa products so several devices can run together with a single tap.

How scheduling can reduce your electricity bill

Devices in standby still draw power even when you think they’re “off”.

TVs, games consoles and chargers left in standby keep pulling electricity from the socket all the time. With the KP303, you can schedule an automatic shutdown overnight or during periods when you’re out, cutting this “phantom” usage without having to remember to do it manually.

Energy-efficiency specialists estimate that standby consumption can account for up to 12% of a household electricity bill. Automating power-down for idle devices is one of the simplest ways to start saving without changing everyday habits.

In specialist testing, the strip reacted quickly both through the app and via voice commands. The mechanical click from the sockets when switching on and off feels reassuring and signals that a physical relay has actually engaged - unlike some rivals that only imitate a sound.

What’s missing - and who this power strip is really for

The Kasa KP303 doesn’t track energy usage for each socket individually, something other TP-Link models such as the HS110 provide. If you want per-device spend tracking, it’s worth looking at versions that include that feature. The power lead is also fairly short, which can restrict placement in some rooms.

Even so, for anyone who wants straightforward routines, easy home automation and voice control without complication, the Kasa smart power strip offers a lot at a competitive price. It’s particularly well suited to home offices, TV rooms and bedrooms where multiple electronics share the same mains outlet.

A smart home can start with one socket - and grow at your pace

The TP-Link Kasa range is a well-established ecosystem, with individual smart plugs, bulbs, cameras and switches that all work inside the same app. If you start with the KP303, you can expand your home automation over time without switching platforms or learning entirely different systems. It’s a building-block approach: each new device fits in with what you already have.

Home automation is no longer something reserved for high-end homes. With affordable products like this, turning the coffee machine on before you get out of bed - or switching everything off with one command - is already realistic for anyone with Wi‑Fi and a smartphone.
