Review on CRE C1 Mini Portable Projector, Compact Pico Size with Full Enclosure for Outdoor Movie, Full HD 1080P Video Support, Ideal Kids Gift, 50,000Hrs LED Lifespan, TV Stick, PS4, HDMI, TF, AV, USB, Cell Phone Compatibility by David Banks

So this is what we got for Thanksgiving. The projector is very light and small enough to move easily. The bottom one is roughly the same size as the iPhone. The height is like a can of soda. We put it on the bedside table and projected it on the bedroom wall, which didn't take up much space at all. The fan can get a bit noisy after hours of filming, but I think it's fair enough for the price. Set up was easy too. We streamed a couple of 4K movies via USB and plugged into the back of the projector, plugged in the power and flicked the power button from the bottom up. Here it is. Everything else can be controlled via the remote control. We tried the HDMI connection to the computer and it worked fine. For portability reasons, I'd try using USB and possibly a phone as the input source. I also like the simple and plain design. Once we know how to get a compatible battery, we'll definitely take it with us on our next hike (no battery included). I can't wait to see the looks from our roommates when we pull out this little device.
