In today’s demanding production environments, time is power—and nothing slows a shoot down like waiting for batteries. That’s why the Rolux RL-4KA (Model: 4KS) exists: a 4-channel simultaneous Gold Mount battery charger designed for professionals who need maximum efficiency, reliability, and versatility in a single powerhouse unit.
🔋 Charge 4 Gold Mount Batteries — Simultaneously
Unlike sequential chargers that power one battery at a time, the RL-4KA charges four Gold Mount batteries at once, each with an output of 16.8V at 3A. That’s up to 67.2V of total output capacity—a huge boost in workflow speed for multi-camera setups, large lighting rigs, or ENG teams needing rapid battery turnover.
No rotation. No delays. Just full-speed charging across all four channels.
🔌 Built-In 15V DC Adapter Output for External Powering
Beyond battery charging, the RL-4KA is also equipped with a dedicated 15V 4.5A DC output (Max 67.5W). This adapter function allows you to power field monitors, LED lights, wireless systems, or camera rigs directly from the charger—eliminating the need for a separate power brick on set.
This makes the RL-4KA not just a charger, but a versatile power station that supports both prep and production phases of your workflow.
🌍 International-Ready Input Voltage
The charger accepts AC 100V–240V input, making it compatible with global power standards. Whether you’re in a European studio or on a remote shoot in Asia, the RL-4KA adjusts automatically for regional voltage—no converters or step-down transformers needed.
💪 Built for Studio and Field Use
While robust enough for professional studios, the RL-4KA is still compact and road-ready. With a solid build and efficient airflow, it performs reliably in high-demand environments. Its working temperature range supports long hours of use, even in warm or dynamic shooting conditions.
- Charger Size: 256 × 118 × 188 mm
- Charger Weight: 2750g (Approx. 6 lbs)
Despite its power, it remains relatively compact for a 4-slot charger, making it an easy addition to DIT carts, studio racks, or mobile charging stations.
