Has anyone seen or have experience on this topic? Having a small compact
Honda 4 or 5 hp attatched with an
alternator to charge their
batteries. I have heard of someone selling an actual
diesel water-cooled unit also. Doing so you don't use your engines to charge. Ok I know,
solar and windgens are all the way but this seems like a good solution for someone that desires to have a spare source of
power, if needed thus like a booster pack but that actually works when you need it.
