Too cold for batteries but just for kicks;
2Ah(3x3.7V)=22.2watts.
Voyagers RTG’s left earth producing about 470watts so that powerbank with 3 x 18650’s would equal about 3 minutes. Not sure what the usage is though so maybe longer, plus the RTG’s power output fades over time so probably longer again.

Ah, cool that is very interesting!
