It is hiking time! The first short summer trip was to test out the 10 watt Waka-Waka solar panel and the 10 Ah battery pack. We strapped it on the back of pack and walked directly charging the smart phone and in about an hour it was charged. Once we found a nice spot in the forest to set up camp I connected the battery pack (350 gram) to the solar panels (740 gram) and they charged well in the full sun (6 hours to get 5 Ah). The two pieces weigh just over one kilogram and have the benefit of charging tech devices such as action cameras, tablets, head lamps and phones.
The trip was a success and Waka-Waka kept us charged up for the trip.
