[Richard and Rhonda]

I don't think the question was ever answered, what is the difference between a converter and a charger? In generic terms, a converter converts 110 AC to 12V DC up to it's amp rating. No batteries are required. A charger also converts the 110 AC to 12 DC but has usually has smart circuitry to alter the amperage based on the voltage of the batteries.

Why would this make any difference? I don't think the chargers like to run without a battery bank. I don't know why. And the converters, without some smart circuitry can cook the batteries.

And I am probably totally wrong.
