ULANZI Camera Cooling Fan Black New, Spring Telescopic Mounting Adjustable Mini Intelligent Cooling Fan Real-time Monitoring with Type-C Charging Port, Compatible with Sony Canon FUJIFILM Nikon

Ulanzi is make much better products. This thing made my Canon R5 MkII last way longer. Temperature just stay cool and I dont have to worry about it anymore. Quality feels great. Noise level is normal. I rather work with the sounds at any given speed than have my camera turn off because the temperature is too much. I wish it had a speed dial instead.

Good product

I bought one of these a while ago for my canon R6 which often overheats and shuts down while recording 4k videos. I have a camera timer that automatically stops and restarts at the 30 minute mark so I can record longer presentations with just a few seconds gap in the middle. But often using that, the camera would still shut down a little way into the second video from overheating. I added one of these ulanzi fans and the camera now can run continuously for a couple of hours without overheating whatsoever. I've never had to use the fan on the number two setting, and it keeps the camera pretty cool. It's also very quiet on the first setting and doesn't interfere with shotgun mics mounted on the camera. I haven't tried it with the built-in camera microphones. I think that might be an issue though. But with an add-on shotgun it is not a problem . A little pricey for what it is, but for me it is well worth it. I also bought a second one for my other camera as added insurance, even though that one doesn't overheat. Highly recommend this to anyone who has issues with their camera overheating.

To begin: Start by recording on airplane mode!!! Turning off network features, Bluetooth, etc will drastically improve thermals. This thing works insanely well. I can record a much longer time than I ever could on my A7IV. Heat dissipation is great. Plugging this in will provide it a bit more juice and help it run longer... Obviously. My only gripe, as well as other people's, was how it falls out of the camera. You can find cheap rubber stickers on Amazon to put on the ends of this to add friction and prevent it from sliding around. This is a cheap game changer for me which keeps this device stable. There is some fan noise that will get picked up by the internal mics, but if you're using external, no problems. This thing is versatile, plenty adjustable, and I can easily recommend it to anyone needing an improvement to the thermals on their camera.

Great fan for the ZV-E10, solves overheating when recording in 4k, the only bad think is that battery won’t last for long recordings (so you would have to keep it connected to power)

I don't know who writes the reviews about this fan not fitting or falling out, they either do something wrong or buy it for wrong camera. Works great for my sony zv-e10 II. Fits very snug. Love the fact that it actually has a built-in battery, so I don't have to run extra wires to the camera. Has 2 modes and the fastest one does not make that much noise (as some people say) + if you use external mic - you're golden. Without dummy battery method it can last for me for about 1.5-2 hours 4k in medium heat environment (hot summer), which is way better than 15-30 minutes before it overheats without it.

Beat the Sony A6700 overheating problem with the Ulanzi Cooling Fan. This tiny beast keeps your camera cool for long shoots, 4K recording, and outdoor heat. If you shoot weddings, content, or travel videos, this is a MUST-HAVE upgrade!

Got the job done. Bought specifically to use on my Canon R6 mki because it overheats In extended 4k use. Did a test in a hot garage and it kept the camera for more than I needed it to last, which is about 45 to 50 minutes for long wedding ceremonies. Did test it in a Catholic Church for a Catholic wedding which is usually really long and it held up. The ultimate test will be outdoors in the summer either, Texas or Florida to see how well it holds up. Fits the back of the camera really easily, can be used plugged in or with the built in batteries charged. Batteries aren't removable. Its also a 1 button operation press n hold to turn on single press ro change the speed. The fan has 2 speeds. So far so good.
