Who It's For

The core spec here is independence: three outlets you can switch or schedule separately, plus two USB ports for steady charging. That layout works well if you have a mix of devices near one outlet, like a lamp, a fan, and a router, that you want to manage on different schedules rather than all-or-nothing. ETL-certified surge protection covers the electronics plugged into it, and setup runs through the Kasa app over your home WiFi, with no separate hub to buy or manage.

This fits a home office, entertainment center, or bedroom nightstand setup where you want to turn off a few specific things on a timer, say lamps at bedtime or a coffee maker in the morning, while leaving always-on gear like a modem plugged into the USB ports. It also suits anyone already using Alexa or Google Assistant who wants voice commands added to a power strip without extra hardware.

Buyers rate it 4.6 out of 5 across more than 16,000 reviews, which points to consistent satisfaction with how the strip performs and how the app works in daily use.

Skip this one if you need every outlet, including the USB ports, to be individually schedulable. The two USB ports are always-on and don't get their own app controls, so if per-port USB scheduling matters, look at a different Kasa model or a competing strip that breaks out USB control separately. It's also not the right pick if you'd rather avoid an app-and-WiFi dependency altogether and just want a plain surge protector.

Bottom Line

This is a solid pick for anyone who wants separate scheduling and voice control over a few devices sharing one power strip, especially in a home office or media setup. It's not the right choice if you need independent control over the USB ports too, or if you want to avoid app and WiFi dependency entirely.
