Game Controller Adapter 300mAh Variable Voltage 510 Battery -White

The SMYLE Labs Game Controller Adapter 510 Cart Battery gives retailers a novelty-forward battery option built for customers who game, stream, or keep a controller close by. Designed to mount to most standard gaming controllers, this compact 510-thread battery uses a magnetic plate system to keep a compatible cartridge battery secure, accessible, and out of the way during gameplay. The use case is simple, visual, and easy to explain at the counter: a 510 cart battery made for gamers. Its magnetic mounting design works with many popular controller styles, including Xbox-style, PlayStation-style, Switch-style, and PC gaming controller layouts, while avoiding the need to hold a separate battery during a session. Each white adapter features a 300mAh rechargeable battery, USB-C charging, preheat mode, and four variable voltage settings: 2.5V, 2.7V, 3.0V, and 3.6V. The included height adapter helps support cartridge fit, while the magnetic mounting plates make setup quick for compatible controllers.
