If I went and got another battery charger, how could I be able to
determine if that one would "like" the power that my genset does deliver?
Is there a way, something to look for in the specs, some charger- feature to
avoid that may make a different charger work ok ?
  If I could get another charger that was willing to work off my Powermate
PM0401853 rather than shelling out almost a thousand bucks for a second
generator (and I dislike generators anyhow) it'd be perfectly acceptable for
me to have to move the generator and a battery charger around to the
batteries and 'manually' charge them back up if they get low after a cloudy
period or whatever...
  This powermate generator has worked fine for me on the job running power
tools.  It did have a cable (with a lighter type fixture and some clamps) to
charge batteries directly off the genertator but I never could get that to
work and I've lost that now.   I do show those power point type sockets
supply adequate 12dc after I 'excite' the generator by pluging a tool into
the 110v ac and running it for a second...  Maybe I never did that in my
past attempts to charge directly off the generator...
