A:AnswerSorry I'm revising my earlier answer. It probably will work with an elite controller. But it may be hard to align the controller with the micro USB charging point. It was hard to align my two custom Microsoft Xbox one controllers. But it work with your controller cause there maybe a difference in size.
A:AnswerThis will work with the new Xbox controllers, just it may be a little bit more of a challenge to get both to work at the same time, due to them being resized a little.
A:Answerthis works with all the xbox one controllers. As far as I know, they are all the same. I have an original xbox one controller as well as a xbox one x controller charging on mine.
A:AnswerAn exact time for how long the batteries last cannot be given as there are too many factors that influence the battery life. These batteries are 1200 mAh which is a larger battery size so they should give you quite a bit of time before needing recharging.
