Recharging Unknowns

I will be camping for 48 of 58 nights and some campsites will be primitive, with varying degrees of electricity and wi-fi available. It’s difficult to try and conceptualize what kind of power I will have available to recharge all the electronics I am taking with me. The things that will need charged are the bike computer, bike front and rear lights, iPhone, iPad, iPad keyboard, GoPro camera, and flashlight. I’m leaving my electric toothbrush and electric shaver at home.  Because of this, I’m taking a small solar battery to carry on the back of my bike while I am riding, and I have a front wheel generator hub to produce power while I ride. This generator will power my headlight and taillight and have an auxiliary USB port to power something of my choosing, like my bike computer or my phone.
