My old Schumacher charger kicked the bucket after two decades or more of faithful service. I have been looking online for a replacement. I now have a headache from trying to find a simple basic charger. Mine had a switch for automatic or manual charging. It had a switch for 2amp 6 volt or 10 amp 12 volt. It also a switch for regular batteries or deep cycle. It was also a portable type. I don't want an onboard type nor am I thrilled about the "fully automatic" types currently offered. So I guess my question is, does anyone offer a portable charger like I described above anymore?
