Perfect for my 11 day backpacking trip in the sierras. I tested it out at home, and wasn't super impressed at 1st. It would charge my samsung galaxy s7 about 30% in 20 minutes, not bad. But when I took it to the sierras, I remember getting about 60% in 20 minutes. I was hiking at 9,000 ft - 12,000 ft during my trip, the sun is very intense up there and I suspect that's why it was working better on my trip. My 1st test at home was at sea level. This charger kept all my stuff powered the whole time and is perfect for adventures above the treeline. It also seems durable. I had it strapped to the outside of my 45lb pack and would lean my pack against boulders, with the solar panel in between and had no problems
