These Star Plastic Bottom Stamped Chargers are stamped with DFX Discs Bar Stamp.

Innova says:

The Charger is a straight-finishing, 13-speed driver that can be thrown at full power without worrying about the disc flipping over. The Charger fills a gap between the Destroyer and the Shryke. For players looking for the consistency of the Destroyer with less fade, try the Charger. For those looking for the big distance of the Shryke, but in a disc that can better handle the wind, try the Charger.
