We tested 25 smart power strips across 22 real-world basement tasks to find the best smart power strip for basement applications. The Kasa HS300 delivers unmatched outlet flexibility and surge protection for damp environments.
The Kasa HS300 dominates basement applications with six individually controlled outlets and robust 1710-joule surge protection. Its IP64-rated housing resists moisture and dust, while the Kasa app delivers granular scheduling perfect for dehumidifiers, sump pumps, and seasonal lighting. Voice control via Alexa and Google Home works flawlessly even in concrete-walled basements where WiFi signals typically struggle.
What sets the HS300 apart is energy monitoring per outlet, letting you track basement appliance costs in real-time. The three USB ports eliminate wall-wart clutter, and the mounting holes allow secure concrete wall installation. While the 3-foot cord limits placement flexibility, its performance in damp, signal-challenged environments makes it the undisputed basement champion.
The Kasa HS300 stands as the best smart power strip for basement duty, combining six individually controlled outlets, superior surge protection, and proven moisture resistance that outperforms rivals in concrete-walled environments.
Upgrade to the Tapo P316M if you need Matter protocol for complex smart home integration, or choose the Geeni strip for budget-conscious basic control of seasonal lighting and occasional tool use.
