I have been using LibreOffice on macs for years and years. It’s a truly cross platform, local office suite that doesn’t mess up my spreadsheets.

I bought the Jackery Explorer 100 and am coupling it with a 45W panel. I figured the Jackery would be better for solar than an average power bank, because they already package it in a bundle with their own panel. BUT since both USB C ports on the Jackery can do both power in/out, I think the Jackery can actually get confused about whether it’s supposed to be charging or discharging, when the panel is running at very low output… … at least, that’s how I interpret having returned to it and seeing it discharged when connected to the panel.
