Portable generators.
 

My ac only pulls 700W
I was thinking HondaEU1000i
Would a larger unit like the 2000I be quieter because it wont have to idle up as much to supply 700W ?

You will not regret the Honda 2000. Your AC may pull 700w but it could take 1200 at startup.

kinda pulls 15 amps at starting and my 1000 is not enough... i would guess 2000 is the key

7.5 amps at start up , so 900watts .
2000 would be better in that case .

I run a 2000 portable. My AC rips 35 amps at startup. On my cruiser 16,000 BTU would pull 60+ amps at startup. I ran a HF Predator 3500, best generator inverter I have ever owned. It now supplies power to my 40'x50' pole barn.

I have owned many Honda 2000's over the years (maybe 15?) and they are great generators. I needed one fast this past summer and bought a Harbor Freight Predator. I still like the Honda better, but the Predator is damn good for 1/2 the money.

Buy the Honda 3000. It’s super quiet and will run 12 hours on a tank full. My younger brother has one he uses on his trawler that probably has 10 thousand hours plus on it and has never missed a beat.

The 2000 is great but will only give you 6 hours on a tankful running a window shaker.

I have been doing some research and it seems the internal guts for most of these are the same.
I was thinking :

Mostly because it has cool colors lol

I don`t want anything too heavy or expensive.
I`d only use it sparingly to cool the cabin while on water or maybe an overnight on the water once or twice.

The 3000 gets pretty heavy. I'd opt for the Predator 2000if you want a good generator at a good price. Keep in mind, 2000 is surge (with Honda also), running watts is 1600.
