Review on 🎥 COOAU Portable Outdoor Movie Projector: 5500 Lumens, 1080P Support for Home Theater Experience. Perfect for Daytime Indoor Viewing with TV Stick/Smartphone/Laptop/DVD Player/PS4 Compatibility. by Trey Dikici

I bought this for a presentation I needed to give in front of 60-70 people from my laptop. Setup was pretty easy once we figured out what type of cable was needed to connect my laptop to the projector. I strongly recommend that you test it at least once before using it. My IT technician struggled to find the right cable as the one that came with it didn't work. The photos were good. Sure enough. But the sound is not very good. We tried all sorts of settings but the audio wasn't loud enough for the room we were in and it wasn't very big. Also, it was noisy. So the motor (or fan?) was so loud that the audio of the presentation was distorted and weak. No matter what my IT staff tried, we couldn't get clearer sound. I sent it back after one use as it didn't meet my needs. I think it would be fine in a much smaller space; maybe 15' x 15'. However, for professional use, you may need a better quality machine.
