Photographer, Jeff Stasney documented some of explorer Robert Swan's excursion across the South Pole this winter in Antarctica (Robert Swan pictured below).
Robert is the only man to walk across both the south and north poles.
Jeff is a CPAP user and took our 48PRO with him on this incredible adventure.
When returning, Jeff commented - “your battery worked great, even in the cold”.
He used the EXP PRO solar panel to charge up his battery during the day.
Thank you Jeff for your trust in EXP PRO batteries to handle the elements and ensure needed rest for this incredible journey.
