We run two Honda 2000I's one of which is the companion model which has the 30 amp female outlet. Have been very happy with the Hondas they are easy to move around don’t weight much are very reliable and very quiet also can be serviced by a local Honda dealer if need be. Most of the time we run one to charge trailer batteries but together they handle the AC well and only run about half speed with the ac load , I would recommend the Honda or Yamaha . We also use an extended run fuel tank when running both together and they will run all day and night if needed ( ran all night at home during a power outage not in a campground).
