I tried this at two points of my life when I was without a laptop and it is excruciatingly inconvenient. The good thing about having a laptop is that you don’t have a headless device with you and it has a battery. The fact that you have a laptop makes it better but then you would be bringing two devices, or three if you include a smartphone, etc., and their power bricks and / or chargers. I also tried transporting a screen but there is a risk of damaging it.
