It has built-in rechargeable batteries that will last about 6–8 hours before you need to plug it in to recharge. The controller itself is lighter than most, with wide handles that help your thumbs rest comfortably on the symmetrical joysticks. It's powered through a USB-C connection but comes packaged with a USB-C to USB-A cable to make things easier. The controller is built similarly to other gaming controllers and features both Wi-Fi and Bluetooth connectivity. The Share button allows players to instantly share a clip of their gameplay directly to Youtube, while the Google Assistant button connects you right to Google's assist features, allowing you to ask questions, swap between input sources for Stadia, and much more.
The Stadia controller comes equipped with two buttons that other controllers won't: the Share button and the Google Assistant button. Built like a normal gaming controller, the Stadia controller has a few key features in it that can take your gaming on Stadia to the next level.
While other controllers may offer more compatibility and customization, if you want to get the most of Google Stadia, you'll need the Stadia controller.
