    A portable solar panel is a good alternative power source for extended trips.

    This 10W Allpowers solar panel is lightweight and compact, outputting enough power to charge a smartphone or USB battery pack.

    A 10000mAh Xiaomi Mi Powerbank 2 (charges an iPhone 6 3.7x) was charged from empty to full over 5, 7-hour sessions.

    In total, ~35 hours of sunlight on fairly clear, sunny days.

    In contrast, it required 8-hours to charge the same powerbank connected to a mains powered USB charger.
