I got what I wanted
Personally, because of my daily travels, I sometimes don't spend all my nights at home. Looking for a solution that suited my lifestyle, I opted for a mobile projector, and I have to say I'm not disappointed. In the evening, I can enjoy my favourite animated series thanks to my Chromecast connected to my M1 mini without the slightest hitch. However, there's a slight problem with the battery, especially when I connect the Chromecast to the USB port. To compensate for this, I use a small power bank, but when I'm on mains power, everything works perfectly.
An interesting feature of the projector is that it automatically adjusts the trapezoids, which is particularly useful when it's correctly positioned and stable.
