The power factor thing can be a real problem when trying to charge batteries through a normal charger...ie, using the generator's 120VAC into the charger's AC input. The charger presents a very high inductive load to the generator which, as mentioned above, would require a disproportionitly larger generator. But the solution to that, although counter-intuitive, is to add a couple of 25w or so light bulbs in parallel with the charger....the change in power factor more than offsets the effect of the extra load. Alternatively, a better solution would be to add an AC capacitor rather than the bulbs...either a 'motor start' or 'motor run' variety purchased at an appliance store....Sears, for instance.
