Review on 🎮 Enhance Gaming Experience with Xbox One Controller Battery Pack: 2 Rechargeable Batteries + Quick Charger by Amy Patton

Simply plugs into my XBox 1's USB port and has an indicator light to show when it's charged. It also has error detection that indicates when you have a bad battery. It comes with two sets of batteries, so you can put one set in the controller and the other in the charger. Much better than a controller charger because I can be ready to go with battery changes taking less than a minute instead of hours of charging at controller charging stations.
