In today’s fast-paced production world, every gram counts, and every port matters. The Rolux Density I delivers high-capacity power in a compact V-Mount form, engineered for filmmakers, photographers, and content creators who need versatility, portability, and intelligent charging — all in one battery.
Ultra-Portable, Fully Featured
Weighing just 730g ±10g and measuring 120×91×55mm, the Density I fits seamlessly into any mobile rig without compromising on performance. Its 98Wh capacity (14.4V, 6.84Ah) strikes the ideal balance between airline-safe portability and serious power output for professional gear like cinema cameras, field monitors, LED panels, and wireless systems.
Power Wherever You Need It
The Density I offers a range of output options that cover all your essential devices:
- BP Electrodes: 14.4V / 15A out, 16.8V / 3A in
- D-Tap: 14.4V / 15A out, 16.8V / 3A in
- USB-C: up to 65W output and 45W input — perfect for powering or recharging laptops, tablets, and mirrorless cameras
- USB-A: 5V / 2.1A output for mobile accessories and smaller devices
This combination of professional-grade and consumer-friendly ports makes the Density I a true hybrid battery — equally suited to powering REDs and Blackmagics as it is to keeping your MacBook or iPhone alive on location.
Intelligent Bidirectional Charging
Unlike traditional batteries limited to one-way power, the USB-C and D-Tap ports on the Density I support both input and output. That means you can:
- Charge the battery via a 45W USB-C PD charger or D-Tap adapter when you’re on the go
- Output power simultaneously to multiple devices while charging, maximizing efficiency during shoots
Whether you’re running from set to set or working off-grid, this smart charging flexibility reduces the need for bulky chargers and keeps your gear ready at all times.
Built for All Environments
From freezing tundras to scorching deserts, the Density I keeps working where others fail, thanks to its wide operating temperature range (-10°C to 60°C). Charging is also safe and efficient between 0°C and 40°C.
