Our take

The KP303 is the budget-friendly sibling of the HS300, trading energy monitoring for a much lower price and a smaller footprint. It gives you 3 individually controlled smart outlets plus 2 always-on USB-A ports, all behind ETL-certified surge protection. The Kasa app handles remote on/off, schedules, and timers, and it ties into Alexa and Google Assistant with no hub. It will not tell you how many watts a device draws, but it does let you fully cut power to chosen plugs so they stop sipping standby electricity, which covers the main energy-saving use case for most people at a fraction of the cost.

What we like

  • Inexpensive entry into the trusted Kasa ecosystem
  • 3 independently switchable outlets cut standby drain on demand
  • Reliable scheduling and remote control with no hub
  • Compact and easy to fit behind furniture or a desk

What to keep in mind

  • No energy monitoring at all
  • Only 2 USB ports and they are always-on
Best for: Budget shoppers who want app-controlled outlets to kill standby power without paying for metering.
