Full-day shooting without battery swaps – thanks to up to 12-hour operating time
Manufacturer specification lists operating time of up to 12 hours, designed for continuous shooting through most of the working day.
Long runtime reduces the need to change batteries mid-shoot, so setups stay uninterrupted and crews can focus on composition and movement.
Rapid top-ups between takes – with 18W fast charging via USB-C to USB-C
Supports 18W fast charging and reaches a full charge in approximately 2.5 hours when using a USB-C to USB-C cable as recommended.
Short turnaround on charging windows lets operators restore substantial runtime quickly during breaks between scenes or events.
Flexible power management for live shoots – with quick-release design and separate charging
Quick-release mechanism allows easier replacement and more compact storage, and separate charging enables replenishing spare units independently from the gimbal. Charging while in use is supported to keep the gimbal powered.
Separate charging and rapid swaps support continuous workflows, allowing one grip to charge while another powers the gimbal during long sessions.
