SKU CH-8DWC-51MJP MPN KP303

A three-outlet smart power strip with two USB ports, surge protection and voice control via Alexa or Google Assistant

  • Control 3 outlets and 2 USB ports simultaneously with independent switching
  • Protect sensitive electronics from power surges with ETL-certified surge protection
  • Manage devices remotely from anywhere using the Kasa Smart mobile app
  • Automate on/off schedules and timers to reduce power consumption
  • Operate hands-free via voice commands with Alexa and Google Assistant

Three-outlet smart strip for home and office

The TP-Link KP303 delivers three independently controlled AC outlets plus two always-on USB ports in a single surge-protected unit. It connects to Wi-Fi and is managed through the Kasa Smart app on Android or iOS. Voice commands via Alexa or Google Assistant provide hands-free operation.

Suits users who want per-outlet scheduling

Households that need individual timers for lamps, fans or humidifiers will benefit from the separate outlet control. Buyers who require more than three smart outlets or need USB ports that can be switched off remotely should look at a different solution.

ETL-certified surge protection

The strip carries ETL certification, meaning it shields connected electronics from voltage spikes caused by lightning or short circuits. This single safety rating is the key specification that determines whether the device meets your protection requirements.

Questions about this item

Will the KP303's three individually controlled outlets work with my existing non-smart lamps and fans?

Yes, each of the three smart outlets can be turned on or off independently through the Kasa app or voice assistants, so your current lamps, fans or other appliances become controllable without replacing them.

How do I confirm the KP303 is protecting my equipment from surges after I plug it in?

The strip carries ETL-certified surge protection; the indicator light on the unit shows the protection circuit is active once the strip is powered.

Does the KP303 package include any mounting hardware or extra cables, or do I need to buy them separately?

The box contains the power strip with its built-in right-angled flat plug and the two always-on USB ports; no mounting screws, brackets or additional cables are included.
