Review on Get Longer Gaming Hours With Our 4-Piece Rechargeable Battery Pack Compatible With Xbox One/Xbox Series XS And Charging Station by David Citizen

These things have solid battery life, are easy to charge and they come with 4 backplates: 2 for Series S/X, 2 for Xbox One. So you can use them for either, making them very versatile. However, performance aside, having a micro USB charge port instead of the Type C that the controller actually uses is a huge miss. Total no-brainer, and they missed the mark. But they do work really well.
