Well the trailer I bought did not have any batteries so I bought the 2 new 6volters new and paid the core.
So it sounds like running that portable with only the 10 amps option is not much an option ... my on-board charger is a 40 amp but it is hooked up right now and only shows 13.22v on my cigarette light meter so I'm not sure if it's really putting out the full 40 amps to charge my batteries.
Is running the 25' jumpers form the truck the best option and letting the truck run for half an hour or so?
What out out my options will give me the best charge in the short amount time.?
