The current onboard charger was probably an overkill and the AC-DC conversion was generating heat, ergo the charger cooling fans kicked in often?
This I am curious to see. Would in effect be lugging around a transformer since it would have to do the AC-DC conversion now? I am guessing the size may double or triple that of the current one.
I feel they should not. The white alien eggshell looks better in a public grid point than this.
