Product information


Off Grid Adventurer Bundle

The combination of the ultra compact 6000mAh Lithium ion battery pack with the flexible, waterproof and lightweight 5W booster panel delivers enough energy to meet the demands of more power hungry devices or multiple gadgets from smartphone and action camera to satellite phone, so there is no need to carry spare batteries that take up space and weigh you down. 

Freeloader Supercharger 5w will charge the Freeloader Sixer in just six hours (empty to full).

The Freeloader Sixer was used by epic endurance athlete and Solar Technology International Ambassador Sean Conway when he broke the world record for the fastest cycle ride across Europe last year. Read more about Sean here.
