1.3mm, centre pin+ would be about right. Also if being used in the ISS then the jack is best to be a 90 degree or if straight then very short with no cable restraint, mostly just use the jack, throw away the screw on plastic cover and heat shrink

However, Supercap does not seem to charge without the solar panel. The CR123A I think would make sense to keep, because if the mains power goes out you still got something that can transmit if your circuit to the station fails, or everything fails and you have your console on battery backup or something.
