You aren't looking hard enough. The link I posted earlier says "22h runtime". That might not include navigation.

The Lezyene says 22 h. If that's optimistic, 12 or so hours out of it might be reasonable.
Depending on the size of the "power bank" you are considering, it shouldn't be too hard to recharge (the battery isn't likely to be more than 1000mAh).
Note that keeping your phone off is something to consider (especially, if you are in a area with no or poor cell reception).
