Small and Powerful
5 Stars
Small and Powerful
These are great little generators. I work with a non-profit that does disaster response and the other small generators that we have used for years are no longer being manufactured. When we started looking for replacements, I wanted something with a good brand name behind it, small and compact, powerful, and easy to transport and maintain. These are usually used when there are disasters and people need them to provide temporary power for their homes.I ordered one of these to test it and then ordered nine more once I determined this was what we wanted. These are compact and have the frame all the way around them for ease in carrying and for protection. They are super easy to start and run smoothly and efficiently. One great thing about these is that they come with everything you need to get started (sans gas) in that there is a funnel and a bottle of oil that contains the exact amount you need. I wish there was somewhere to store the funnel and tools that come with it, but I'll likely tie a mesh or other bag to them.I'm very pleased so far and will use these for our next disaster. One tiny little thing that could improve these is if they would include holes for your hands in the box so they would be easier to grasp and move. That's a very small thing but when you are moving lots of these just a little handhold on each side would be so helpful.

5.0 out of 5 stars PERFECT for my application
Reviewed in the United States on July 27, 2020
Okay, so here's the TL;DR

Awesome generator for a camp trailer. Amazing bang-for-your-buck in comparison to popular brands. SUPER quiet. Quieter than I expected. Weighs less than expected. Starts very easily. Ran my AC unit no problem. Very fuel efficient.

Full review:

This thing is absolutely perfect for what I needed. I have a 30' travel trailer with a 15,000BTU AC unit, and my main concern was running that periodically while boondocking.

I looked at the "red" 2200i's because that's what my in-laws run, but I would have needed 2 of those to run it (like they have done.) That puts me in the ~$2,300 price range. Other 'cons' to this approach: 2 engines to maintain, and 102 total lbs. (I try and travel as light as possible, so I'm always thinking about weight). The 'pros' to this approach: it has the right name on it, serviceable pretty much anywhere.

Anyway, back to this one. The first thing I noticed was how light it is. It only weighs slightly more than a red 2200i. It is a little bigger, but not by much. It fired right up on the first pull (make sure it's on 'choke' as it doesn't seem to start on 'run' even when warm).

The next thing I noticed was how QUIET this thing is... I just got back from a 4 day camping trip with some family that have some standard generators and man... I'm glad I got an inverter generator. That's all I'll say. I checked my dB meter and it put it right on with ONE of my father-in-law's running. However, the GP3000i beat his two running parallel while still providing enough power to run the AC. Another observation was that even though it registered the same, it still seemed quieter. I think possibly due to the Generac running at a lower frequency. It just felt less annoying.

Needless to say, it ran my AC flawlessly. I didn't try to run much of anything else while running AC, but it ran that and all the LED lights in my trailer no problem. There's no doubt in my mind that it would run everything in my trailer at once, except maybe the microwave simultaneously. Never really use that thing anyway, though.

My last observation was how well it conserved fuel. I would fill it up about 10:30-11:00 at night, turn on Eco mode, and let it sing us all to sleep. By 7:00-8:00 in the morning it had kept my furnace running all night and still have about 1/3 tank left. Came home with about 2 gallons left in my 5 gallon gas can.

So I can't speak to longevity, durability, or repair-ability yet. But I will update my review if/when I get that experience. However, at the moment I'm VERY happy with my purchase. I saved ~$1,500 going this route with little to no compromises in sight.
