At $22 (with promo code TECKIN22), this smart power strip costs about as much as a standard smart plug, but it includes four smart AC outlets that you can control individually with your smartphone or Alexa, plus four USB ports too (though you can only control them as a set).
The free control app and Alexa will recognize the power strip as five different devices (four AC outlets, and the USB ports as a group) , all of which you can name, schedule, connect to your favorite voice assistant, and control from anywhere.
