I'm going to be homeless and jobless for at least the next summer and maybe autumn and I want to use this "opportunity" to try and spend that time outdoors in the woods. The plan is to only have to go to a store once a week or less to stock up on food.
Now for the real question: powerbanks are heavy and I would need at least 2-3 to last a week or more + recharging them would take a long time. How are solar rechargeable battery banks? I would be out 24/7 and in Finland meaning the sun sets after way past midnight and rises really early on. Would a normal sized bank recharge at least half way in a single day? If so, any recommendations for brands.

Also, homeless thread I guess.
