This controller charger station simultaneously stores and charge 2 controllers. 

This stand model makes the controller sit in a regular position to better connect with the controller. Charge the controller directly on the charging dock; and the rechargeable battery directly. The LED indicator checks the power level of your XBOX and shows Red light when charging and turns Green when it's fully charged. Charge fully within 3 hours that gives 10-15 hours of playtime. No need to worry about any interruption during the game; as it provides continuous power; and no need to worry about overcharging as it won't damage the controller even if you forget to remove the battery in time.
