@Azgal posted:thanks so much for the reply, now I know why everyone loves their EU2200i Hondas! I do a lot of camping at 8000' do you think it could hand 1200 W at that altitude?
Simple answer...yep!
Longer answer is...if most of your camping is above 5,000', Honda highly recommends getting a carburetor jet made for altitude. Otherwise the gen will run on the rich side (air/fuel mixture). The only problem with re-jetting the carburetor is that if run at low altitude with a high altitude jet, it will run lean which can cause problems.
Before giving up on the Costco gen, see if it can be re-jetted for high altitude. It's unlikely but that little boost in power might be all that's necessary. Or, if you're able to...maybe take it back for a refund. Costco is extremely lenient.
