Direct sunlight ,positioned as pictured, Gained 6% charge to a Klarus 10K in 30 minutes...
In the Shade of a tree in ...30 minutes ...1% so 5 hrs of shade 10% at best
Intermittentddirect sunlight ,hiking for eat 8hrs + 1hr stop , worst I can hope for is 20% . My days are likely to be 9-10hrs walking ,with 1.5hrs stops ,worst case 25% , best case a full charge plus surplus .
If I run my phone down to 10% , Charge to 90% ,I can get 2 x 80% charges + top up watch /torch/earbuds if needed from a full charge with the Klarus .
summary ...1 full charge of the Powerbank should give me two days heavy use of phone . 3 to 4 days light use . Bearing in mind ,I'm travelling south to north ,average daylight will be around 17hrs daylight , so even if only 8 are optimal , it should be enough to keep me out of gaol .
I've a few days to experiment with conditions ,/ How different powerbanks receive trickle / max availabile charge .
worst case ,I might swap the Klarus out for the Huawei 12k or carry the NB air to keep purely for fear/emergency.
I reckon that I could redneck the positioning ,so it's entirely almost horizontal whilst walking on non technical stretches ,to achieve the best results.
It will be a learning curve for sure ,but as long as something is continually plugged in ,every mah is a gain .
