Best Power Strip Smart Plug in 2026, Reviewed and Ranked

Why you should trust this guide

I have spent years reviewing smart home gear and writing buying guides for TheTestedHub. My approach is straightforward: I read through hundreds of verified customer reviews, cross-reference official specifications from Amazon listings, and compare features side by side. I do not rely on marketing hype or unverified claims. Every recommendation here is based on the real-world features and limitations listed by the manufacturers.

For this guide, I focused on five widely available power strip smart plugs that cover different needs and price points. I considered factors such as the number of smart outlets, USB ports, surge protection ratings, energy monitoring capabilities, and voice assistant compatibility. I also paid close attention to safety certifications like ETL and FCC, as well as any setup requirements like 2.4GHz WiFi only. The result is a clear, honest ranking that helps you choose the right product for your home or office.

How we evaluate

I evaluate power strip smart plugs based on five key criteria: number of independently controlled outlets, USB charging capabilities, surge protection and safety certifications, smart features such as app control and voice assistant compatibility, and any special features like energy monitoring or Matter support. Each product is scored against these criteria using only the features listed in the official Amazon descriptions.

I also consider practical usability factors like the type of plug, cord length, and whether the device supports individual or group control. I do not test products in a lab or take physical measurements. Instead, I rely on verified feature lists and customer feedback to assess reliability and ease of use. The ratings reflect how well each product meets the needs of a typical buyer, not an expert or a power user.

Kasa Smart Plug Power Strip KP303

The Kasa Smart Plug Power Strip KP303 offers three independently controllable smart outlets plus two always-on USB ports, letting you support five appliances at once. It works with Alexa and Google Assistant for hands-free voice control, and the Kasa app gives you remote access from anywhere. The ETL-certified surge protection shields your electronics from sudden power surges, and you can set schedules and timers to turn outlets on or off at specific times to save energy.

This model is ideal for home or office use where you need a few smart outlets and USB charging without extra complexity. The USB ports are always on, so they do not interfere with the smart outlets. The KP303 is a reliable, straightforward option for anyone looking to control lamps, fans, or small appliances with voice or app commands.

Kasa Smart Plug Power Strip HS300

The Kasa Smart Plug Power Strip HS300 is the most feature-rich model in this guide, with six independently controlled smart outlets and three built-in USB ports for charging devices. It includes ETL-certified surge protection and energy monitoring, so you can track how much power each connected device uses and turn off those that waste electricity. The Kasa app allows remote control from anywhere, and it works with Alexa, Google Assistant, and Microsoft Cortana for voice commands.

This power strip is perfect for home offices, entertainment centers, or small businesses where you need to manage multiple devices and monitor energy consumption. The 3-prong plug adds stability, and the surge protection gives peace of mind during storms. The HS300 is the best choice for anyone who wants full control and energy insights.

GHome Smart Power Strip Surge Protector 10A

The GHome Smart Power Strip Surge Protector 10A supports voice control via Alexa and Google Assistant, and you can manage it remotely through the GHome app. It offers timer, schedule, countdown, and random modes for basic automation. Each smart outlet can be controlled individually, and you can group multiple outlets for one-tap control. It is ETL and FCC certified with surge protection, rated for 120V/10A (1200W max), and requires a 2.4GHz WiFi network.

This model is a good entry-level option for beginners who want to automate simple routines like turning on lamps or coffee makers. The 10A rating limits it to lower-wattage devices, so it is not suitable for high-power appliances. The setup notes emphasize stable networks, making it best for non-critical devices in bedrooms or small home setups.

Tapo Smart Wi-Fi Power Strip

The Tapo Smart Wi-Fi Power Strip connects and surge protects six individually controlled smart AC outlets and three always-on USB ports (5V 2.4A). It tracks energy consumption for each AC outlet, helping you cut costs by scheduling devices to turn off when not in use. The slim design features a flush-fitting plug for tight spaces behind furniture, and a 3-foot power cord. It includes overcharge prevention that shuts off outlets when devices are fully charged, and it is Matter-certified for compatibility with Alexa, Google Home, Apple HomeKit, and Samsung SmartThings.

This power strip is the best choice for users who want broad smart home ecosystem compatibility. The Matter certification ensures it works seamlessly across platforms, and the energy monitoring and overcharge protection add practical value. The slim design is a bonus for placement in cramped areas.

GHome Smart Power Strip 9-in-1

The GHome Smart Power Strip 9-in-1 features three smart outlets with individual control, three smart USB ports with group control, and three always-on regular outlets, for a total of nine outlets. It supports voice control via Alexa and Google Home, and remote management through the GHome app. You can set timers, countdowns, recurring cycles, and random modes. It is FCC and ETL certified with overload, overcurrent, fuse, and surge protection, plus a V0 fire retardant shell. Rated for 3450W 15A, it handles high-wattage devices like air conditioners and fridges.

This model is ideal for users who need to power heavy appliances while still enjoying smart control. The combination of smart and always-on outlets offers flexibility, and the high wattage rating makes it stand out. Note that the USB ports only support group control, not individual control, and it requires 2.4GHz WiFi.

What to look for

• Number of smart outlets: More outlets give you greater control over individual devices. Consider how many devices you need to automate.
• USB ports: Built-in USB ports are convenient for charging phones or tablets without using a smart outlet. Check if they are always on or group-controlled.
• Surge protection: Look for ETL or FCC certified surge protection to safeguard your electronics from power spikes.
• Voice assistant compatibility: Ensure the power strip works with your preferred voice assistant, such as Alexa, Google Assistant, Apple HomeKit, or Cortana.
• Energy monitoring: This feature helps you track and reduce energy usage by identifying devices that consume too much power.
• WiFi requirements: Most smart power strips only work on 2.4GHz networks. Confirm your router supports this band.
• Wattage rating: For high-power appliances like air conditioners or fridges, choose a model rated for 15A or higher.
• Matter certification: If you use multiple smart home platforms, Matter certification ensures broad compatibility.

The verdict

After comparing all five products, the Kasa Smart Plug Power Strip HS300 is the clear winner for its combination of six smart outlets, energy monitoring, surge protection, and broad voice control. For budget buyers, the Kasa KP303 offers reliable smart control with fewer outlets. The GHome 9-in-1 is best for high-wattage devices, while the Tapo leads in ecosystem compatibility with Matter support. The GHome 10A is a simple, affordable entry point for basic automation. Choose based on your specific needs for outlet count, power requirements, and smart home integration.
