Review on 📽️ ManyBox Mini Projector: Compact & Durable with 45000 Hrs LED Lamp Life, Full HD 1080P Supported. Ideal for TV, PS4 & More - HDMI, VGA, TF, AV, USB Compatible by Guillo Tilden

I've had several projectors over the past 19 years and one of the biggest complaints I've had is that the replacement bulbs cost SO MUCH. As a result, I hardly ever used them and they started gathering dust in the back of my closet. When I stumbled across this projector I was intrigued by how relatively cheap it was and I was curious if LED projectors could outperform the older ones I have. So I decided to try it for the last 20 days to see how well it works. PROS - Multiple connection and input options including USB sticks and wireless connection via Miracast/Chromecast - Fairly bright output even at around 100 inch projection size. - Amazingly loud speakers - uses ONLY 35W of power! -- Runs on my 400W battery pack for 8-10 hours! Fun for kids on the go - Much quieter than my old projectors - Traditional image correction controls (zoom/focus/keystone) - Remote control - Small and portable - LED lamp lasts much longer than older projectors - 3 year warranty. That surprised me a bit! CONS - Requires AC power and cannot run on battery (that's not what the product is designed for, but wanted to point out) - Manual may require some work - Native 480p resolution (frankly, many mini projectors don't have a higher native resolution) - No Bluetooth support for connecting wireless speakers. I was very surprised, how much power this little projector has compared to the older projectors I own. LED technology has come a long way, and because LEDs run much cooler, turning off the projector doesn't require a cool down period like it used to. Even better, connect some high-quality speakers via the headphone jack for a pretty good movie experience. I am very confused as to why the product description on Revain says this projector is not recommended for PPT (PowerPoint Presentations). Why not? It is great for business presentations. If the meeting does not last longer than 4 hours, can it get a little hot during this time? I'm not sure. The instructions also do not state why the manufacturer does not recommend using it for business presentations. In any case, I look forward to using this projector more often to watch movies with my kids. The 2020 version has been upgraded from 3500 lux to 4500 lux. To convert to lumens, this is not a simple formula. Lux takes into account the surface.
