I have 2 Honda EU2000i generators and was going to pick up the Parallel cable that will allow me to increase my capacity beyond the 2000watts. The problem is that If I want to run my AC, I'll have to use a receptacle rated for 30 amps and the generator only has 15amps. I've seen this little gadget and am considering it...
Maybe this will help others run AC. I dont know if the 3000i has a 30amp plug.
*Edited* - I guess this probably should have gone under electrical.
