For large-scale productions, high-capacity power solutions are essential to keep cameras and accessories running throughout long shooting days. The Rolux Density III 290Wh USB-C V-Mount Battery is designed for exactly that—delivering extended runtime, versatile outputs, and rugged reliability for professional filmmakers and content creators.
High-Capacity Performance
With an impressive 290Wh (20,100mAh at 14.4V), the Density III offers significantly longer runtime compared to compact V-Mount batteries. This makes it ideal for powering cinema cameras, field monitors, lighting, and other high-draw accessories on extended shoots without constant recharging or battery swaps.
Flexible Power Options
Equipped with multiple interfaces, the Density III ensures compatibility across a wide range of devices:
- BP Electrodes – 14.4V 15A output / 16.8V 3A input
- D-Tap Port – 14.4V 15A output / 16.8V 3A input
- USB-C Port – up to 65W output and 45W input, perfect for laptops, cameras, and modern accessories
- USB-A Port – 5V 2.1A output for smaller devices and mobile gear
This versatility allows you to power traditional cinema equipment and USB-powered devices at the same time, reducing the need for multiple power sources on set.
