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.
