I use a MacBook Air M2 with 8g Ram/256 memory; stick my laptop, Focusrite soundcard, USB hub, and an iPad for ForScore, on a standard music stand; no need for AC for a 3 hour gig as my Keylab and Focusrite run on USB power from the Mac. Mac is running MainStage with Analog lab and UVI Grand as plugins. No problem yet.
Strap the Keylab to my back, QSC K8 in one hand, bag with wires & electronics in the other, and I'm in and out. Keyboard stand, bench, and music stand on second trip, or use my cart for all, fitting it in my Mini Cooper..Enough room for a groupie too. I travel small and light - dragged around too much gear in big cars for too long
