Upgrade 3D Hologram Advertising Display Fan 17.7 inch, 800 P Hi-Resolution and WiFi Added - LED Light 3D Holographic Projector Fan for Business Store Shop Bar w/800pc Video Library 45 cm

I bought this fan (20.5in model Z7H) to try mount onto an extendable pole to use as a rave totem to display animated GIFs that I can change on the fly from my phone. The device itself is cool and works very well, once you figure it out and learn the limitations. The APP (3D LED FAN for iOS) is in broken English and is not intuitive at all to use. There is no bulk upload feature and no way to organize the hundreds of different animations I wanted to upload. It will play everything that is uploaded in the order it is uploaded, with no way of picking and choosing which images to display. It will read most image file formats and MP4 videos, but it does NOT support GIF playback. It just displays the first frame. For this issue, I made an iOS shortcut that converts a GIF to MP4 and loops it for X number of seconds. PROS: - Surprisingly bright. At 100 brightness it can easily be seen in direct sunlight. - Decent picture quality, considering its a fan. Images are pixelated and have rings up close, but look fine from a few feet away. - Runs at 12V 4A DC, but can run off a portable USB-C power bank with this adapter: USB C to DC 12V Adapter - Has easy access UART pins and is easy to root (more details at bottom) CONS: - HIJACKS BLUETOOTH SPEAKERS! Whenever this fan is on, it repeatedly tries to connect to any Bluetooth device in range, and just appears as some generic name. I was unable to play any music through my stereo while it was on as it would connect every 60 seconds and kick my phone off. There is a setting in the app for "Volume Control" with an on/off toggle. Turning this off stops it from doing this, but does NOT save, so this setting will be on again after a reboot... - Creating an account for some cloud service hosted in China is required to remotely manage the device. However, it will make it's own network and can be connected to directly and managed offline if you are within Wi-Fi range. - Management APP is terrible - Impossible to get good video of, as cameras pick up the spinning. Lower refresh rate video works better. TECHNICAL DETAILS: This fan runs on an Allwinner V3s ARM SoC with 32MB of RAM, as well as a proprietary FPGA to control the LED display. The system itself runs Android 4.2.2 with a process named mplayer that controls display of the image and initialization of the system. It hosts a busybox FTP server on a static IP of 192.168.10.123 that the app connects to to upload files. Managing the images is a lot easier with a 3rd party FTP app. However, for it to recognize new images were added/deleted, you must upload something with the official app after you make any changes. I have been unable to locate a full firmware image, but partial updates are available from a Chinese file server found with a quick google search. ADB is disabled out of the box, but I was able to patch the mplayer process and replace the system command to format the SD card to instead start the ADB process. EDIT 10-2-25: Well, 2 years later still works great, but these hologram fans have gotten much cheaper than what I bought it for in 2023 and I'm a bit peeved lmao. Spent $250 on this :/

We bought a few months ago. I finally had some time to put this together. The graphics really pop-out when you turn this on. The instructions are not great (not very clear or detailed). Once I figured out how to get graphics on this it blew me away. I tried the cubes for creating and then found I liked straight photos and graphics more than the cube layouts provided. You can adjust the order the graphics appear, the length, and how many times it will play before it advances. It rotates through what is loaded. I put over 100 graphics and pictures on. I made graphics on my computer. Then I uploaded to an iPhone. From there I installed into the app. There is a computer software available but only for a PC not a Mac. Not supporting a Mac is my greatest complaint. Otherwise it is great! The comments from attendees at the conference has been nothing but positives. Lots of stunned and impressed viewers. It drew people to my booth. As a result I have had more opportunities to share our nonprofit story.

I really like the product, but we've struggled with the instructions, setup and with poor customer support. Its a quality product, but is useless if you can't program and operate it. Sincerely; Customer needing help ClarenceO

This is a great display/ trade show attention getter. For the extra money go with the 65S version as the build quality is much better than the standard 65 unit. The customer service is also good. After you receive give a few days for back and forth communication. The instructions in Chinese were not much help and the documentation is poor. Once up and running it is very cool.

Verified Purchase — This GIWOX 3D hologram fan exceeded my expectations. The image is bright, sharp, and very eye-catching, even in a well-lit room. Setup was fast, and uploading content through the app or TF card is straightforward. The fan is sturdy, runs smoothly, and is perfect for grabbing attention at events or demos. Great value for a professional-looking display.

Shows promise. Looks great on the wall. Been able to transfer two photos. Unclear if it can handle more than two at a time. It does have instructions but the print is a little too small. Would be nice if they were more clear.

This product will drive you crazy at first for 5 legit reasons. First, the directions are terrible. Second, it takes forever to find the app. Third, the app is not at all user friendly and the directions for the app don't exist. Fourth, there is no customer service available. Fifth, you're not going to find a youtube video, or video provided by the company, anywhere that shows you how to setup and use this hologram fan. It took us HOURS to figure out the first steps, and then the next day the app said our password wasn't correct so we had to start all over. That was two days ago and we're still waiting for their Customer Service people to email us back. Still.... even with this product only working at 50% it is still freaking amazing and well worth the money we spent. Hopefully some day we will get the videos to upload and work as well as jpgs. One day the videos work fine. The next day the app won't allow you to upload the exact same videos that use the same mp4 format. Don't ask me why.... customer service never wrote back to give us an answer. Seriously... if you're from China and you' ae selling something in the USA, just pay a US customer to write your instructions for you! And then have them make a simple setup video for you. Or do it in trade. It will save the rest of us hours of frustration and the aggravation of discovering that you actually wrote your instructions from back to front rather than from front to back. But nobody in the US knows because you didn't number the directions. All we know is it's impossible to do what you've instructed. We almost packed this up and sent it back a dozen times we were so upset.

In January of 2019, I did my yearly visit to CES in Las Vegas and was very taken with the new release of all the 3D LED image fans that were coming to market. Upon returning home, I did my research and decided to purchase the GIWOX 3D Hologran Fan. My impressions of the device are great. It was easy to install and set up. You have the option of controlling it from the small included remote, your Windows PC, or your iPhone (might work from a MAC, haven't tested it). To load images, you can upload from either your iPhone of your PC though a Wi-Fi connection. At first I was having a hard time finding images that were formatted correctly for the display, but have a few hours searching around the internet I found images and videos that look and display great. GIWOK also has made available a large library of image files you can download to add to your display that allows you to show off all it can do. You can also create your own images (that is my next project to learn how to make good quality content). I recently had an issue where I accidentally corrupted the configuration on my device. GIWOK was able to assist me with getting the device back up and running again. The tech support has been very helpful and quick to respond. With just one quick email, I got the assistance I needed. I always have some concerns about buying from smaller unknown companies.... Will they be there to support me when I need them, will the you continue to update the applications. If I need help will they respond. In all areas, the answer has been yes (just received an iPhone update yesterday with fixes and improvements). Thanks, Jeff
