TP-Link's Kasa line of smart home products includes this space-saving smart plug. It works with Google Assistant and Amazon Alexa, and the Kasa app offers plenty of detailed options for customizing scheduling, away modes and timers.
What you do not want to get? Energy consumption data, a USB port or HomeKit compatibility. TP-Link's $ 30 smart plug is a great choice.

At just $ 18, this smart plug is the most affordable on our list. It's the smallest. Pair that with energy monitoring and Google Assistant and Amazon Alexa smarts, and you've got a great option for your smart home. The SmartThings Wi-Fi Smart Plug does not work with HomeKit and there's no extra USB charging port. The SmartThings app does offer as many options and scheduling options as TP-Link's Kasa smart plug above, but SmartThings did SmartThings hub.

This smart plug comes with an easy-to-use app, monitors your energy consumption in kilowatt hours (kWh), and works with Google Assistant and Amazon Alexa for voice commands.
The plug's design blocks above or below it, and it is not compatible with Apple HomeKit. Still, the TP-Link's Kasa app is great, and you'll get a clear picture of how much energy your appliance is using.
Unlike some smart plug manufacturers, TP-Link has a host of other Kasa smart home products including light bulbs, cameras and even a power strip, making it easy to expand your smart home in one app.  TP-Link Kasa Smart Wi-Fi Plug-in with Energy Monitoring.

At $ 30, the WeMo Mini Wi-Fi Smart Plug is affordable and comes with native Google Assistant, Alexa and yes, Home Kit Compatibility.
The WeMo app is not our favorite, and you will not get energy monitoring with this plug. Those cases aside, this space-saving design and solid home kit compatibility make it easy to recommend to users in Apple's ecosystem.

The $ 50 iDevices Outdoor Switch is a great way to automate outdoor lights, fans, lamps or other patio electronics. It works with Google Assistant, Alexa and HomeKit and includes energy tracking.
While you will get two outlets, you can not control them individually. If that's a must-have for you, we'd recommend checking out the iClever Smart Plug.

Other models tested
The CNET Smart Home has just come out of business. Here's a quick look at other notable options.
- : Amazon's flagship smart plug costs $ 25 and only works with Alexa. While setup is easy, it is not as feature-rich as other models.
- Satechi Dual Smart Outlet : This Home Kit is smart at $ 60, but you can get two outlets and energy monitoring capability. There is no compatibility with Google Assistant and or Amazon Alexa.
- : This $ 40 outdoor smart plug works with all three voice assistants, but you'll only get one outlet.
- : This $ 60 behemoth does it all-energy monitoring, individually controlled outlets, a USB port and LED status lighting. However, the price and unattractive, oversized design are enough to keep me from recommending it.
- : This $ 32 smart plug works well with HomeKit, but blocks adjacent outlets. Google Assistant and Amazon Alexa integrations are not as smooth as we'd like to see.
- : This HomeKit-centered smart plug is another solid choice for Apple smart homes, but it did not perform well in our testing.
- : This pint-sized smart plug is just over our SmartThings budget pick up and costs just a few dollars more at $ 23. You'll get Amazon and Google Assistant smarts, as well.
- : This two-pack for just $ 15 is incredibly cheap, and it does the basics well. It works with Google Assistant and Amazon Alexa, but there's no power monitoring.
Things to remember
Choosing the best assistant plug-in begins with voice assistant compatibility. Choose a plug that works with whichever voice assistant you're using. You may find this information on the product box, website or in your voice assistant's mobile app.
Next, consider where your plug is located. If so, be sure to pick a plug that is not too large. Most models described as "mini" wants to be space-saving.
Extra features like energy monitoring and USB charging can add even more control and convenience. No matter which smart plug you choose, bringing every product online with a plug is one of the simplest ways to automate and smart your home.
