Install more battery storage capacity, install 300W pure sine inverter. Instead of buying a $500 additional generator, invest it in a modest solar system to keep the batteries charged.

Joe,
That Chinese inverter/charger on E Bay is set up for 220v, 50hz input. You can't use that here, in the US.
Word up on E Bay merchants: If they are charging more for shipping than the item being sold, don't even think about buying the item. You would be dealing with a dishonest seller. With that inverter/charger, they are asking $68 for the item and $99 shipping.
The only inverters that aren't hard-wired are small 100W-200W inverters that plug into a DC cigar lighter receptacle. A 10 amp charger isn't much of a charger, it will take many hours to recharge a battery. Do you have a converter existing in your trailer? If so, you already have a battery charger on board.
Yes, you can hook up an inverter anytime you'd like. What are you trying to power with the inverter?
