The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Kasa KP303 is positioned as the entry-level cousin of the HS300: three individually controlled smart outlets, two always-on USB ports, and surge protection at a noticeably lower price. TechRadar calls it an affordable way to control three appliances remotely without buying separate smart plugs, and Home Depot verified-purchase reviewers highlight easy setup and reliable remote control. r/homeautomation threads echo the broader Kasa sentiment: fast local Wi-Fi response, simple app, good value.
What reviewers liked
- Lowest price of the smart strips covered here while still offering per-outlet control and surge protection
- TechRadar and r/homeautomation both highlight quick setup and responsive local Wi-Fi control
- Two always-on USB ports cover phone and small-device charging without a brick
Where it falls short
- A high-trust r/smarthome thread reports a serious failure incident, which buyers should weigh before using with high-draw loads
- Only three switched AC outlets, fewer than the HS300 or P316M
- No Matter support, and r/homeassistant threads broadly flag the Kasa Wi-Fi line as showing its age

There is one signal that cannot be smoothed over. An r/smarthome post, which reads as a serious first-person incident report, claims a KP303 nearly caused a house fire and that the strip itself did not trip before the breaker did. That is a single data point and not a recall-level pattern across the verified-purchase corpus, but it is the kind of high-trust community signal worth surfacing, especially for anyone tempted to run space heaters or other high-draw loads through a smart strip.
For low-draw applications, three plugs you want to schedule (lamps, a fan, a coffee maker, charging banks), the KP303 is the consensus budget pick. For higher-draw or higher-stakes loads, reviewers are increasingly pointing to Matter-native options or simply a non-smart strip from a brand with a stronger insurance guarantee.
