I’ve been using the Sunslice solar panels since 2021, I initially purchased the single 6 watt version which I used for backpacking and cycle touring, it was excellent at charging up smaller devices such as the Garmin inreach satellite tracker and my Garmin watch. The following year I purchased the double version which gave you two USB ports & 12 watts of power, this has been on 3 overseas backpacking trips so far…

I definitely find that these solar panels seem to work better when they are stationary and my preference is to charge smaller power banks that have a digital display so you can actually see it charging up. Well it makes me feel better anyway 🤣

Both of the solar panels have withstood some harsh treatment including me falling over, me resting on my rucksack on the solar panel on rocky ground, basically me 🤣 and are still working perfectly.
