I would highly recommend it.

Yeah I was planning on charging the batteries one at a time.

I was just curious if that specific charger would be suitable to charge the 12V trailer battery. For the princess auto one it says "Completely charges a battery with the power of a larger bench charger" what does that mean? It makes it sound like I need a bench charger and this is an adaptor.
