Need user instructions for Coleman PMB8110 12 Volt Portable Power Source

You do not want to convert anything to a 220 v connection !!!! Your RV is 12 volt DC and 120 volt AC.
Use a 30amp female to 15 amp male adapter to plug in to regular household receptacle on generator. Available at hardware store and RV stores.

You need to remove the cover where the outlets are at and measure the voltage before the breaker. There are no fuses on the output side of the genset only breakers.
