The best Chromecast devices make it easy to send content from your Android phone to any of the best TVs. Chromecast may be little, but it's had a big impact on the way many of us watch movies and TV shows.
The range of Chromecast devices has ebbed and flowed since the first model shipped in 2013. Sometimes it's felt like Chromecast were everywhere, and then the number of models would reduce again. At the moment, Google only offers two options.
The reason Google only makes two Chromecasts is simple: having established the technology, Google no longer needs to add it to many devices because other manufacturers have embraced the tech too. Many of the best TVs have Chromecast built-in, including budget models you'll find in our guides to the best TVs under £1000 or best TVs under $1000.
Many of the best smart speakers with Google Assistant built-in can be Cast to, and the same applies to many of the best wireless speakers and some of the best soundbars. But for the purpose of this guide, we'll stick solely with Google's dynamic duo.
The best Chromecast devices 2021
Unlike old Chromecast devices that were just for streaming to from your phone, this is a standalone smart TV device, with its own software. It's powered by Android TV, with the new Google TV interface, which is really easy to use and intuitive. It's packed with streaming apps, so is a great option if you're looking to add more services to a TV that doesn't have what you want built in.
With 4K HDR support too, it's a bit of a home cinema powerhouse – it looks great, and supports all major formats. Dolby Atmos audio is supported too.
It also works like previous Chromecasts, in that you can just beam things to it from other devices. It's just more focused at being a smart TV upgrade.
This is more like the classic Chromecasts: you have the ability to cast audio and video content over to a big TV from dozens and dozens of apps across Android and iOS. And that's it! No remote control, no built-in software. It's great for a low-cost upgrade to a TV you want to stream to sometimes, or for presenting to screens in an office.
You don't get 4K support here (just 1920x1080 Full HD), so there's an upper limit on quality. Similarly, there's no HDR support, so you'll get a better quality of stream from, say, Netflix on the Google TV model above than this one, if that's important to you.
But for just turning a dumb screen into one you can stream to, this absolutely does the trick.
