For 3kg you have something that should give 2-3 hours of Internet usage on an average EU/USA good weather day (assuming 20% solar panel for 10 hours = 80Wh/day, 25-35W power usage of Starlink Mini + smartphone).
For each extra 1.65kg you get an additional 2-3 hours, resulting in 7.95kg for 8-12 hours, 11.25kg for 12-16 hours.
- FlexSolar 40W panel: 1.35kg
- Nitecore NB20000 ~75Wh battery: 300g
- Starlink Mini: 1.1kg
- Smartphone: 250g

Not bad, but not good either.
