The battery could care less about power factor.
Yep ..... but a camper using a small-as-possible generator mainly for just battery charging when drycamping will care about power factor.
And since (one of the) ideas behind use of a simple inexpensive manually adjustable power supply is for direct control for fastest possible battery charging - which implies off grid non-solar-availability camping - then power factor correction should be considered for a small generator owner when choosing any power supply for their battery charging.
