Honda 2000i

15A to 30A adapter. I use one of them with our Generac iX2000. I bought one similar to the one in the link and use a heavy-duty extension cord to run from the generator to the adapter. It works out well as the extension cord I use is lighter than the 30A cord. If I have shore power, I use the 30A cord, but for the generator, this is easier.

I bought the Firman W03083, 3000-3300 watt portable inverter gen with manual/electric/remote starting for $749 online with free shipping.  This is the size recommended for 13,500 A/Cs.  Never have to worry about having it start the the AC repeatedly in hot weather with high head pressure (constant restarts of the compressor before it has time to bleed down is a problem with ACs in hot weather).  Plus it's beautiful!  Also it has a 30 amp plug and can run two together with a parallel cable.

I just talked to the guy at Home Depot about adapters and he said I should use a 30A female to 2x120 three prong male (basically a dog bone with a splitter on the male end so that you are utilizing both 120 outlets simultaneously.) Is that right?

Originally posted by GLBCamper SO...can I just plug my male 30A cord from the trailer into a 30A female to 15A male dogbone and plug the dogbone into the generator, start it up and it will charge my batteries?

Yes, that's all you need.  You won't be able to run the air con and the microwave at the same time, but you'll be fine for just about everything else.
