When production scales up, your power solution needs to keep pace. The Rolux RL-4KS is a high-efficiency 4-channel simultaneous V-Mount battery charger, purpose-built for professional cinematographers, ENG crews, and lighting technicians who demand fast, stable, and reliable battery management.
Whether you’re prepping for a long shoot day or cycling batteries between setups, the RL-4KS ensures you stay ahead of power needs—without delays, without compromises.
🔋 Charge Four V-Mount Batteries – All at Once
The standout feature of the RL-4KS is its ability to charge four V-Lock batteries simultaneously at 16.8V, 3A per channel. This means consistent current across every port, with no need for alternating charge cycles. You get faster results, higher efficiency, and smoother battery logistics, especially in multi-camera or lighting-intensive environments.
Ideal for productions using large-capacity batteries, the RL-4KS ensures full recharges without overloading or overheating.
🔌 Dual-Function Design with Built-In DC Output
Beyond charging batteries, the RL-4KS also functions as a dedicated DC power station, thanks to its 15V, 4.5A adapter output (Max 67.5W). This allows you to directly power field monitors, camera rigs, wireless systems, or lights, even while charging batteries in parallel.
No need for extra bricks or converters—just one compact unit that handles it all.
🌍 Universal Voltage Input for Global Use
Whether you’re working in Los Angeles, Tokyo, or a remote documentary set in the mountains, the RL-4KS supports a wide AC input range of 100V–240V, making it globally compatible. It auto-adjusts to regional voltage standards, offering plug-and-play convenience anywhere in the world.
💼 Rugged Yet Manageable: Designed for Field and Studio
With a charger size of 256 × 118 × 188 mm and a weight of 2750g (approx. 6 lbs), the RL-4KS strikes a perfect balance between durability and portability. It’s tough enough for daily studio use, yet compact enough to fit into travel gear kits, charging stations, or mobile power carts.
Its robust shell and ventilation structure are built for long hours of continuous operation—even in hot production settings or outdoor environments.
