That's a nice, big battery. Looks like the solar array would take a long time to recharge it but it will keep some items charged up over a pretty long trip.

I've used one of these: Bushnell Solar Wrap Mini with good success, but its (unstated) battery capacity is much smaller, so I rely more on the solar panel itself. The brilliant bit is how small it is when rolled up for storage. Am hoping they update it with the latest tech for more capacity at the same weight and size.

Cheers,
