Isn’t this the backpack hunting forum? Why are we talking about DeWalt/Makita batteries and jump starters lol? Also from my experience solar chargers that are compact enough for backpack hunting are nearly useless.
You’re looking for something like an Anker PowerCore10,000. Cheap, light and charges my iPhone three times. Comes with all needed cords/lightning cables. Mine never leaves my pack.
From what I've read, the better ones are large and fold out. You leave them in camp to charge. If you're on the move all day with your camp on your back, they don't work so well. Those little ones with a panel the size of a phone would be pretty much useless.
My power pack holds 25,000 mAh. It's a bit heavier than your 10k but it holds a lot of power.
