For some types of work, I carry around 3 power banks if I'm to do a full days work away from power. Max screen brightness + high CPU use of long compiles means I'm averaging 40 watts
Add on a starlink and you need a trolley to carry the weight of the power packs needed.
Sure. For your type of work, that's the only solution.
To clarify, I'm totally fine with powerbanks, especially that these days even the cheapo ones support a subset of PD to charge a laptop (sometimes even 12V is enough, my Thinkpad allows that, I've read somewhere that Framework can charge from even 5V). I'm just not fine with solving an objectively poorer battery management (compared to Macs) by just buying external battery and calling it a solution. It's a workaround at best.
