Doc/SD- that's my point, that Rav unit has like 20X - 30X the surface area of a single cell power bank, and actually puts out a decent charge. If you charge up a power bank before leaving, it makes more sense (to me) to also take something like the Rav unit, since a single solar cell power bank is gonna take 2 - 3 days of time and attention per phone charge. If you're gonna rely on a power bank while camping (and hiking), it seems like a better choice to just get the next size bigger power bank than to try to nurse one of those single solar cell puppies. OTOH, if you schlep something like that Rav unit, you can probably get by w/ a smaller power bank, assuming fair-weather camping (non-tropical winter campers need not apply).
