Modern converter/chargers are much better at charging the batteries, quickly, and not overcharging them, or having high voltage in a park with high input voltage and low voltage in a park with low input voltage.
Converters suffered from those problems because they did not regulate the voltage output, it is a fixed percentage of the input voltage. So a park with low voltage will have dim lights and no battery charging. High input voltage can damage the battery if plugged in a for a long time.
Check Best Converters, link above. THey have great prices.

Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
