Rolux Density III 290Wh USB-C V-Mount Battery: Ultimate Power for High-Demand Productions

When your equipment demands serious power, only a true heavyweight can deliver. The Rolux Density III 290Wh USB-C V-Mount Battery is built for professionals who operate high-draw cameras, lighting systems, and field monitors that require maximum runtime and stability. Combining robust performance with modern USB-C versatility, it’s a powerhouse designed to keep your production running smoothly all day — and night.

Massive Power Capacity for Professional Workflows

At the heart of the Rolux Density III is its incredible 290Wh (20,100mAh) capacity at 14.4V, providing extended operating times for power-hungry cinema cameras and high-output LED lights. This large capacity makes it perfect for long shoots, outdoor productions, and live events where continuous, stable energy is essential.

Even with its high capacity, the Density III maintains a compact, functional design — measuring 120×91×90mm or 120×91×102mm, depending on model — and weighing around 1380g to 1390g, balancing endurance and mobility for professional field use.

Advanced Power Interface System

The Density III offers multiple power outputs and inputs for ultimate flexibility across a wide range of professional gear:

  • BP Electrodes: 14.4V 15A output / 16.8V 3A input
  • D-Tap: 14.4V 15A output / 16.8V 3A input
  • USB-C: 65W max output / 45W max input (supports PD2.0 & PD3.0 protocols)
  • USB-A: 5V 2.1A output

This multi-interface system ensures compatibility with both legacy and modern equipment, allowing you to power traditional V-Mount devices while also charging USB-C laptops, tablets, and cameras — all from a single power source.

USB-C PD: Next-Generation Charging Technology

The USB-C PD (Power Delivery) feature transforms the Density III into a universal power hub. With up to 65W of output, you can easily charge or power laptops such as MacBook Pro, Blackmagic cameras, or field monitors. The 45W input also allows the battery itself to be charged quickly via USB-C — a game-changing convenience for mobile professionals who prefer lightweight, adapter-free charging solutions.

Built to Endure Tough Production Conditions

From extreme cold to sweltering heat, the Rolux Density III is engineered to perform. It operates flawlessly within a temperature range of -10℃ to 60℃, and charges safely between 0℃ and 40℃, making it reliable for outdoor shoots and demanding travel schedules. The reinforced shell design protects internal cells from impact and wear, ensuring long-term durability under constant use.

Professional-Grade Design and Performance

Every aspect of the Density III is built with professionals in mind. Its robust housing, intelligent circuit protection, and stable voltage output guarantee safe and efficient performance for even the most sensitive equipment. Whether you’re powering a full cinema setup or multiple accessories via D-Tap and USB-C, the Density III ensures uninterrupted operation throughout your production day.
