I believe one of the accessories you can buy for the Honda EU1000 generator is the 12 volt cable. Plugs into a special receptacle and the other end clips to your battery. Provides a way to recharge your battery without need of any invertors.

However, it is designed to ONLY charge your battery, not provide 12 volt load power.

Would make a killer jumper pack.  Only drawback is it is a little pricey at $1000.
