The Play & Charge Kit is one of the few accessories for the Xbox One, which is really indispensable. The duration of one battery charge amounts to approx 20h. He is by the supplied USB cable recharged battery in the controller again, the cable is about 2m long, so it should usually up to the bed;) When the battery is charged is a small LED in the connector for the controller to whether it is still loaded (orange) or he is fully charged (white). The charge goes really quickly and even when switched Xbox.
I would recommend the Play & Charge Kit only recommend and do not want to miss it.
