The cooling fan does not have a built-in battery, and supports charging while using or a battery power supply. It recommends using a charger with output voltage and output current of 5V3A, 5V4A, or 5V5A.
【Spring Buckle Install Design】With a newly designed locking spring buckle, the ULANZI CU01 cooler is compatible with most side-flipping screen cameras. The pop-up locking mechanism securely holds the cooler in place, preventing it from falling off, offering a hassle-free experience.

The AUTO mode ensures your camera stays within a safe range (around 8°C), preventing overheating while recording in high temperatures. This ensures smooth and stable performance during extended filming or photography sessions.
【Quiet Operation & Multi-Speed Control】Choose from three adjustable fan speeds to suit your needs: low-speed mode (1), 6.5W，36dB, perfect for silent shooting, or 7.7W with 39.4dB high-speed mode (2) for intense cooling during long recording sessions. The intelligent auto mode dynamically adjusts between 5.8W to 7.7W, maintaining an efficient, quiet operation with noise levels as low as 36dB, ideal for professional and outdoor photographers and videographers.

★★★★★ A Must-Have for All Shooters, Just One Tiny Wording Quibble!I've been using the ULANZI CU01 Camera Cooler on my mirrorless camera for a few weeks now, and it has completely solved my overheating issues. Before, I was worried about my camera getting too hot during long 4K video recordings, especially on warmer days. This little device is a total game-changer.It attaches easily with the spring-loaded mount and holds on securely. The fan is surprisingly quiet and doesn't get picked up by my microphone, which was a concern for me. It starts cooling immediately, and you can feel the difference right away. After a session, the transfer pad was impressively cool to the touch, and I was pleased to see it produced virtually no condensation. I specifically tested it with my Sony A7R5 outside for over an hour in with the fan in Auto Mode, and not only did the camera stay cool, but the cooler itself still had battery left when I got back home. A great bonus is that it also accepts external USB-C power, so you can run it indefinitely from a power bank or wall adapter, with or without the battery pack attached. For any serious videographer or anyone who shoots long takes, this isn't just a nice accessory; it's an essential piece of kit.My only piece of constructive feedback is for the marketing team at ULANZI. The box mentions a "Thermostatic Semiconductor," which isn't technically a real component. From my nerdy perspective, the device almost certainly uses a thermoelectric cooler (TEC), also known as a Peltier device, which is a type of semiconductor. This TEC is then likely regulated by a thermostat. The packaging seems to have just combined the two terms. This doesn't affect the product's performance at all—which is stellar—but rewording it would make it more accurate for the tech-savvy crowd.That minor quibble aside, this is an absolutely fantastic product that does exactly what it promises. It's well-built, effective, and gives me the peace of mind to focus on my shooting instead of my camera's temperature. Plus, as a general principle, electronics that run cooler have a longer lifespan, so I see this as a great investment in protecting my camera for the long run. Highly recommended!

I live in Florida, and prolonged video sessions with my Sony A6700 often meant dreaded overheating warnings and forced shutdowns — especially on hot, humid days. Since installing the ULANZI CU01 Camera Cooler Kit, those interruptions have basically disappeared.Here’s why this little unit was worth every cent:What I LoveReal reduction in temperatureAfter mounting the cooler, the A6700 stayed several degrees cooler under continuous use. During back-to-back 4K recordings, I no longer get the “Camera too hot” message within the first 20–30 minutes like I used to.Smart temperature regulation & modesThe cooler has multiple operating modes (silent, quick, auto), so it only ramps up when needed. That means it doesn’t run full blast constantly, which helps conserve power.Quiet and unobtrusiveThe fan noise is low — I can’t hear it over ambient sounds during filming. It’s subtle enough that it doesn’t interfere with audio or distract during vlogging or interviews.Easy to mount, simple designThe spring-mount design makes it easy to attach under the camera. The magnetic battery is compact and snaps on/off cleanly. Charging via USB-C is convenient too.Improved recording consistencyIn past sessions, I’d have to stop and cool the camera down. Now, I keep rolling through Florida’s heat with far fewer interruptions.Minor Drawbacks & Things to KnowBattery runtime is limitedThe magnetic battery provides around 65–85 minutes of operation (depending on mode) before requiring recharge.B&H Photo VideoSo if you’re shooting long sessions, you’ll want a backup or keep a USB power source handy.Extra weight / bulk under the bodyIt does add a little bit of bulk underneath the camera. On a gimbal or tight rig, you’ll want to make sure it clears surfaces or stabilizers.Only helps when you’re filming continuouslyIf your usage is mostly quick snaps or short clips, you may not notice much difference. Its benefits really shine when recording non-stop for 30+ minutes.Final ThoughtsIf you’re battling overheating — especially in Florida or other high-temperature environments — the ULANZI CU01 is a solid investment. It’s not perfect, but it dramatically improved my ability to film long 4K sessions on the A6700 without frequent shutdowns. For me, it turned those frustrating, heat-limited shoots into smooth, dependable ones.Highly recommended — especially for fellow content creators who film outdoors or in hot climates.

Ainda não tive a oportunidade de usá-lo pois tenho utilizado muito pouco a câmera e não tem esquentado a ponto de precisar acoplar o cooler. Mas o material é super bem feito e esfria pra caramba mesmo. Compra certeira!

I use these on a Sony a6700 and a7IV for long video shoots. They worked very well with no thermal shutdown of either camera for 2+ hours.I did have plug into external power after about an hour and 20 minutes as the battery died. Increased battery time would be a huge plus. I am looking at a few additional batteries to have on hand. They fit the camera snuggly and no worry of it falling off.
