Review on Xbox One Controller Charger and Rechargeable Battery Pack - YCCTEAM | Compatible with Xbox One, Xbox One X, Xbox One S, Xbox One Elite Controller | Xbox One Charging Station with 2 x 1200mAh Rechargeable Batteries by Heather Seay

The dual charging station comes with a charging station, 2 batteries and a charging cable. The first thing that struck me about this set is that the batteries are slightly larger. They're a bit heavier, and I could tell that when I held the controller in my hands. It's not a huge difference, but it does make the controller a bit heavier. When I plug the controllers into the dock, the red light comes on, indicating it's charging. (According to the instructions, the indicator turns green after charging.) I charged the controllers for about 6 hours and the red light still hasn't changed. I ended up removing a controller to use it. The battery icon on the Xbox dashboard was almost full. I'll wait for the other connected controller's light to turn green and I'll update. I don't mind it taking longer to charge as long as the battery lasts long between charges. When connected to the docking station, you can also charge the battery (while it is on the controlled one) connected to the console (or any other) via USB. Aside from the slight heaviness and long loading time, it works great and serves its purpose. I'll let you know how long it holds a charge and how long it takes to fully charge.
