A power bank connected to a solar cell might be a better option. If I were going on a multi day hike far from any electrical outlets, that's probably what I would look into.

Eink requires very little energy. A large solar panel with the size of the screen (behind this) it should be enough... I think.
A few years ago Leia Media (Finland, country not very sunny) propused a ereader with a solar panel integrated... no like the one I propose but it was shown that a solar panel can provide enough energy to an ereader.

I think the problem is the cost. No more.
Sorry my English...
