What to Look For in a Smart Plug in 2021

Most smart plugs have the same general capabilities. They’re able to open or block the flow of electricity to turn appliances on and off. However, this only works if an appliance has a power switch that can be “On.”

In other words, if your appliance can turn on after plugging it into an outlet, it’ll work with smart plugs. If you need to press a button after plugging in an appliance to turn it on, it won’t work with a smart plug. Keep this in mind before shopping for any plug.

Smart plugs can connect to various smart assistants such as Google Assistant, Alexa, Siri, HomeKit, and IFTTT. This allows you to control them with the respective voice assistant–usually through the app and by voice. So, if you have an Echo smart speaker and want to make the most of your smart plug, look for one that supports Alexa. The same goes for other voice assistants. Smart plugs usually can work with all ecosystems, but there are exceptions!

The size of smart plugs is another important factor to consider. Some are incredibly bulky and can take up multiple AC power sockets that are next to each other. Remember that just because a smart plug is bigger doesn’t mean it’ll provide additional features or perform better.

The last thing to note is that smart plugs are essentially the same thing as smart outlets. The main difference is that smart outlets are bigger, which usually provides more sockets for you to plug in numerous appliances.

Let’s take a closer look at some of the best smart plugs on the market.

Best Overall Smart Plug: Wyze Smart Plug

  • High functionality and performance for cheap price
  • Offers vacation mode for added security
  • Able to connect to other smart home devices with IFTTT
  • Wyze app is easy to navigate


  • Doesn't support Apple's Siri
  • Requires a 2.4GHz Wi-Fi network

When you’re looking for a smart plug, you want something reliable, affordable, and provides great functionality. But, you also want a smart plug that isn’t too bulky. That’s why we chose the Wyze Smart Plug as the best overall pick.

The plug works with Alexa, Google Assistant, and IFTTT. Upon downloading the Wyze app, you can easily set up the plug within minutes by following the instructions in the app. It needs to be connected to a 2.4GHz Wi-Fi network, but from there, you can turn the plug on and off, set a timer, create schedules, and track how long the plug’s been on. The smart plug also offers great connectivity, so you can have full control of it wherever you are.

The plug has a rectangular build that’s best suited for outlets with vertically stacked sockets, and you’ll have no problem placing multiple Wyze plugs on top of each other. This makes it great for most uses!

The Wyze smart plug offers great value, especially for its low price of $20 for two plugs. If you’re looking for an individual unit, you can get the single-pack for $12 instead.

Best Budget Smart Plug: BroadLink Smart Plug

  • No need to install a third-party app
  • Offers strong performance and connectivity
  • Fast and easy set up
  • Same capabilities as more expensive plugs


  • Requires a 2.4GHz Wi-Fi network
  • Requires Alexa or Google Assistant
  • Doesn't support Apple's Siri or HomeKit

Looking for a cheap smart plug that can do the job? BroadLink’s smart plug costs just $8 for one, but you can get three for $17, or five for $28. We recommend going for the three-pack as you’re almost getting one for free!

We chose this as the best budget option for several reasons. For starters, it’s definitely one of the least expensive smart plugs on the market, while still providing great value. The plug requires you to have Alexa- or Google Assistant-powered devices, and it also works with IFTTT. There’s no third-party app to download, so you need to connect it to a voice assistant, but there’s a good chance you’re using one of those anyway if you’re decking out a smart home.

Once connected, you can control the plug by voice, set timers, and create schedules. There’s even an Away mode, which turns on the plug at random times to make it seem like you’re at home. The plug uses a 2.4GHz Wi-Fi signal, and it has a rectangular build. You can conveniently stack three of these on top of each other, so you can use them in standard outlets easily.

It’s IP64 water- and dust-resistant, making it safe to plug into areas that have been exposed to rain, snow, dust, wind, and dirt.

The plug costs $16 and works with Alexa, Google Assistant, and IFTTT. You can conveniently use voice commands, the Wyze app, or a smart assistant’s app to control your plug from inside your home.

There are two sockets on the Wyze Outdoor Plug, so you can connect up to two appliances. However, you can control each socket independently, so there are no problems if you need to turn a particular light on or off.

Through the Wyze app, you can quickly install the plug, turn it on and off, set timers, and create schedules. You can even track energy consumption and set alerts for when an appliance uses a specific amount of energy.

Although the plug will be outside, it has an extended Wi-Fi range of 300 feet in open space. This provides you with better connectivity, allowing you to reliably control the plug from around your home. All and all, a great outdoor plug!
