My external portable battery charger somehow disappeared from my garage, so I'm in the market for a new one. I use it to charge my Jet Ski Batteries over the winter, used it to charge my group 27 batteries on my runabout before I sold it, charge automotive batteries when someone leaves the dome light on, charge the spare 12v I keep on my workbench for electronics testing, etc. This is going to be for occasional home use, not charging batteries for a trolling motor or anything like that. I previously had a portable DieHard charger that supported AGM and flooded, had three different charging speeds from trickle to fast charge, had jump-start capabilities, etc. I was happy with it and probably wouldn't be replacing it if it hadn't disappeared. What brands and models have you all had good luck with?
