Elfin

If you are a Netflix consumer, Elfin Flip Plus, if you are not a Netflix consumer (I only use Stremio) The old Elfin has 4k support, higher brightness, memc support and moves extremely well! Plus the 0.33 chip, larger than the Flip ones! I was undecided between the three too, I chose the old one with android tv! Plus, with an adapter like this https://www.amazon.de/dp/B0F1YG7VK1?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1¤cy=EUR and a 65w battery with power delivery you make it truly portable. You can replace the power brick with a smaller and easier to transport and install 65-100w power supply.

Check this, you have here dangbei atom and benq gv50: https://youtu.be/jmmGQOSAReI?si=mk5zE9Dv7LKLEVwe Xgimi elfin flip is a little weak and it has a proprietary software. Better is the old version of elfin (similar with halo+ on performance). I have Xgimi Halo+ and I like it very much. I use it in my living room in the evening for movies and with ps5. I bought it new with discount at aprox 500 eur last year. Wanted dangbei atom or benq gv50 but at that time were both at 700-800 eur…

If you have a Apple TV, save the money and buy the Elfin non plus model - it's the same projector but without Google TV.

Xgimi elfin is vantasic. Has auto keystone correction so you don’t struggle to line it up with the screen.

From my experience, 300 real ansi lumens is enough for dark room I gifted my friend Xgimi elfin some years ago For the budget projector check https://youtu.be/vHmy8sobWEc?si=IjGRLxh_TsuV3hj_
