The Ulanzi CU01 Thermostatic Semiconductor Camera Cooler Kit is designed to help manage camera temperature during extended filming and other demanding shooting sessions.
Its cooling system combines a thermoelectric chip with 71 pairs of PN junctions, high-density aluminium heat-dissipation fins and a 5000 RPM fan, providing active cooling across a stated 5580 mm² area.
Three operating modes let you choose between quieter operation, faster cooling and automatic temperature management. In AUTO mode, an integrated NTC temperature sensor is designed to maintain the cooler at approximately 8°C, helping manage temperature while reducing the risk of condensation.
This kit also includes the 3000mAh magnetic battery, providing up to approximately 85 minutes of operation depending on the selected cooling mode.
The Ulanzi CU01 is designed for photographers and videographers who need additional camera cooling during longer or more demanding recording sessions.
Its spring-loaded mounting system is designed for flip-screen cameras, while the included battery makes the kit particularly useful for location work where you want active cooling without relying continuously on an external power source.
The CU01 combines several cooling components into a compact unit.
A thermoelectric chip featuring 71 pairs of PN junctions works alongside high-density aluminium heat fins and a 5000 RPM fan to move heat away from the camera.
The stated cooling area is 5580 mm², providing a broad thermal contact area for the compact cooler.
The CU01 provides three operating modes so cooling behaviour can be adapted to the shooting situation.
Level 1 is intended for situations where quieter operation is preferred.
The supplied battery specification gives an approximate runtime of 85 minutes in this mode.
Level 2 prioritises faster cooling when greater thermal management is required.
Approximate battery runtime is stated as 65 minutes.
AUTO mode uses the integrated NTC sensor to manage cooling automatically.
The system is designed to maintain a temperature of approximately 8°C, helping prevent unnecessary cooling and reducing the risk of condensation while managing power consumption.
Approximate battery runtime in AUTO mode is 65 minutes.
An LED indicator provides real-time temperature monitoring.
Together with the NTC sensor, this allows the CU01 to automatically manage its operation when using the intelligent temperature-control mode.
The CU01 uses a pop-up spring mounting system designed for flip-screen cameras.
Its adjustable width ranges from 74 to 94.5 mm / 2.91 to 3.72 inches, allowing the cooler to accommodate compatible camera bodies within that range.
The spring-loaded design helps maintain contact between the cooling surface and camera.
A thermally conductive contact surface helps transfer heat from the camera to the active cooling system.
The cooler combines aluminium alloy, plastic, silicone and copper construction, bringing together the structural and thermal components required for the cooling system.
This kit includes Ulanzi's dedicated 3000mAh magnetic camera cooler battery.
The battery has a capacity of 3000mAh at 3.7V / 11.1Wh and attaches magnetically for a more portable cooling setup.
Confirmed approximate runtimes are:
Charging time is approximately 2 hours.
Both the camera cooler and battery feature USB-C connections with a stated 5V / 2A specification.
A charging cable is included with the complete kit.
The camera cooler measures approximately 94.4 x 53.2 x 25.5 mm and weighs approximately 106g.
The included battery measures approximately 59 x 59.2 x 20.3 mm and weighs around 70g.
This compact construction keeps the cooling system relatively portable for location and studio camera setups.
The CU01 provides active thermal management in a compact package designed specifically for compatible flip-screen cameras.
Its semiconductor cooling system, 5000 RPM fan and aluminium heat fins provide active cooling, while three operating modes let you balance noise, cooling performance and automatic temperature management.
The included 3000mAh magnetic battery makes the complete kit particularly useful for mobile shooting, providing up to approximately 85 minutes of cordless operation depending on the selected mode.
