The "smart" charger I bought to replace the original ferromagnetic type
in the Navigator (that was cooking the batteries) was similar to this one.

Not the same brand and the one I got had 60 amps per output (3 outputs).
It was of a switching power supply design and was smaller and much
lighter than the ferromagnetic type it replaced.

I'm not familiar with that one but looks like a solid unit. After
some bad eperiences with Charles Marine chargers I've switched over to
this one for my engine starting batts and generators:
