Cooling Fan Kit Ulanzi CU01 for Mirrorless Cameras (UL4671) USB-Powered, Clip-On

The Ulanzi CU01 cooling fan kit is a compact, clip-on, USB-powered fan designed for mirrorless cameras to help manage heat during prolonged shooting sessions. The unit attaches to the camera body or camera rig and directs continuous airflow toward the sensor area and internal electronics, reducing the risk of thermal shutdowns and performance throttling during video recording, time-lapse captures, or extended studio and outdoor use. The kit emphasizes portability and ease of use for field work while maintaining a low profile so it does not interfere with common camera mounts and accessories.

Advantages

The clip-on design allows quick attachment and removal without tools, and the USB power option supports connection to cameras with USB power output or to external power banks for flexible operation. Its lightweight construction minimizes added weight to camera setups. Continuous airflow helps stabilize internal temperatures, potentially extending recording times and maintaining consistent camera performance under sustained load.

Suitable for

• Long-form video recording with mirrorless cameras
• Time-lapse photography and interval shooting
• Outdoor shoots in warm environments or direct sunlight
• Studio sessions with extended continuous operation
• On-location fieldwork requiring a portable cooling solution

Key specifications

• Mounting type: clip-on attachment compatible with camera bodies and rigs
• Power input: USB-powered for connection to camera USB port or external power bank
• Airflow: continuous low-noise fan designed for directed cooling of sensor and electronics
• Weight: lightweight construction suitable for portable setups
• Compatibility: intended for mirrorless camera models and typical camera cages or rigs

How to use

Position the clip-on fan so that airflow is directed toward the camera’s sensor area or heat-generating components, ensuring the clip grips securely without obstructing any buttons, articulating screens, or accessory mounts. Connect the fan to a USB power source such as a compatible camera USB port, an external battery pack, or a USB power adapter. Verify that the fan operates quietly and that the camera has full range of motion needed for your shooting configuration. For rigged setups, adjust the clip placement to avoid contact with lenses, filters, or external microphones.

Usage recommendations

Use the fan when recording long video takes, during extended time-lapse sequences, or when operating in high ambient temperatures. When possible, pair the fan with a stable power source and check periodically for secure attachment. Avoid placing the clip where it could block vents needed for the camera’s own cooling system, and keep the fan clear of dust and debris to maintain performance.
