The Ulanzi CU01 Thermostatic Semiconductor Cooler is a high-efficiency cooling device designed to prevent camera overheating during extended shooting sessions. With a smart thermostat, adjustable cooling levels, and a pop-up spring mount compatible with most flip-screen cameras, it ensures safe, reliable, and rapid cooling for professional and casual use.
The Ulanzi CU01 protects your camera from overheating during long recording. The semiconductor cooler with a 5000 RPM fan clips onto a flip-screen camera with a spring mount.
A thermometric chip with 71 PN junctions, high-density aluminium fins and a 5000 RPM fan draw heat away from the camera body. The NTC sensor holds a constant 8 °C, prevents condensation and saves power.
No overheating even after an hour.
Silent, fast and automatic.
An LED shows temperature and mode.
Spring mount, no tools.

The cooler uses semiconductor cooling with a thermometric chip with 71 PN junctions, high-density 6063 aluminium alloy heat sink fins and a 5000 RPM fan. A magnetic protective shell dissipates heat and a thermal silicone pad carries it away from the camera body.
Silent mode (level 1), fast cooling (level 2) and AUTO mode with intelligent temperature control. A real-time LED indicator shows the temperature: blue light below 36 °C ±3 °C, red above it.
A thermal image after 1 hour of continuous recording at a room temperature of 27 °C shows a minimum temperature of 2–5 °C with the Ulanzi CU01 and 8.5–13 °C with a cooler from another brand. The data come from the Ulanzi lab.
On top you will find the pin contacts, the temperature indicator, the function button and the gear indicator, on the side the Type-C port and a magnet. The underside carries a highly efficient thermal conductive surface and the spring mount.
The Ulanzi CU01 Thermostatic Semiconductor Cooler is a high-efficiency cooling device designed to prevent camera overheating during extended shooting sessions. With a smart thermostat, adjustable cooling levels and a pop-up spring mount compatible with most flip-screen cameras, it ensures safe and rapid cooling. The pop-up spring mount holds the camera without loosening, while a real-time LED indicator monitors temperature. Lightweight and compact, it is made from aluminium alloy, plastic, silicone and copper.
