Xbox One controllers come with a power cord, but if you want to use them without batteries, there are a few things you can do. First, make sure your Xbox One is turned off and unplugged from the wall. Then, hold down the Xbox button on the controller and plug in the power cord. The controller will start up and be ready to use. If you want to use your controller while it’s plugged in, just press the Xbox button again to turn it off. You can also hold down the Xbox button and press the power button at the same time to turn off your controller completely. If you ever need to charge your controller, just plug it into an outlet and wait about 10 minutes for it to charge. ..
