You could always buy a USB-c battery pack. I got one from Dell with my old laptop and it seems to be able to charge the Framework 1.5 times. I have a Ryzen and get about 9 hours between charges, the battery pack would theoretically add another 13-14. I used it at a conference when I hadn't charged the framework the night before, and it charged it to 100% and was a bit below 50%.
