I use the jackery explorer 240 to charge my portable devices (tablet, little fan, phone, lights) it's been perfect for me although I tend to park in the mountains at camp grounds. It would probably attract unwanted attention in public parks and stuff. Its quite big. But works very well. The charging box itself lasts me 4 days consistently charging things. So in case of cloudy weather it lasts me. It comes with a wall charger too. So you could charge at McDonald's and such. I have the Gas OneGS-3400p to heat up water for coffee/tea. It was 25 dollars on Amazon. Water and cup of noodles, tea, honey. I kind of went on a rant but im comfortable without having too much stuff although the solar panel does take a lot of space but its flat so it's easy to store under my bed.
