How do you keep your electronics charged up while /out/ long term? I'm talking 4+ days.
I'm thinking of going for solar power with this

The other option is to take a few fully charged portable chargers but if they break or get used up, you're screwed. There's wind up chargers but none of them have good reviews and it seems like a gimmick.
So i'm not sure. It's pretty important for me to use my tablet while /out/.
