Update December 17, 2019
Rainier's support responded within one day and has also opened a phone line. They updated the manual to include valve adjustment specifications. Does not appear to be difficult. Will check and adjust the valves. Expect to get full performance again from the generator for powering my saw and, possibly, my 80 amp arc welder. There are no other generators with the added power in this price range as far as I know. Glad I researched and chose Rainier. Going to buy another one.
Update December 15, 2019
Glad to report that the generator powers 15 amp tools including saws. It will still not power my small stick welder probably because of rush current exceeding the rating. The low amperage stick welder needs a full 20 amp circuit and this generator is just shy of that amperage. The big challenge now is that Rainier recommends checking and adjusting valves after 100 hours but does not provide the specification for valve clearances. Still glad I chose this generator. It starts about as easily now as it did brand new. It is still super quiet and extremely fuel efficient. With less than 500 watt power draw, I can easily run 10-14 hours on the efficiency setting from one fill-up. Impressive.
Update November 6, 2019
I have about 180 hours on this generator running everything from electric chain saws, shop lights, drills, smaller saws, finicky batter chargers, and fans. I am glad I bought it yet surprised and disappointed that it will stall when I attempt to run 120 VAC/15 amp mini welders, a smooth start saw from Evolution Rage, and other tools that are supposed to run on 120VAC/15 amp circuits but overwhelm this generator. When I first received it, the generator would power these devices but no longer.
I use synthetic oil and replace it at around 50 hours. The manual states that I should check the valve clearances but does not provide the instructions to do so, other than taking it to a service station.
Still a great generator that I would buy again and recommend. If I can solve this heavy load issue, it will be perfect.
I own more than 10 generators because I live off-grid. My main generators are from Champion Generators with solid performance over the years combined with outstanding support. After researching for weeks to find a fuel efficient inverter generator that could support a 90 amp welder or several battery chargers that require clean power, LED lights, drills, saws, etc., I finally settled on Rainier Power Equipment's R2200i. Here are the reasons why I chose this inverter generator over the ones from Champion, Costco, Ai-Power, Wen, and many others: 1) 1800 running watts vs most competitors at 1600 watts. While the difference seems small, in practice 200 watts is enough to run my shop lights and 1800 watts is enough to run my 90 amp welder. 2) Fuel gauge. Several generators leave this nice feature out. I use the fuel gauge to assess how much time I have left in the tank. 3) Super quiet at 52 db. You will not believe how quiet this unit is! I often listen to podcasts while working and can hear them even near the generator. Other units are 58 db. 4. Larger tank and run time. 1 gal vs 1.3 gals makes for another 30% work time vs competitors. 5. Eco-mode and 13 hour run time. The eco-mode responds instantly to changing loads, dramatically reducing fuel consumption. Some competitors do not have this critical feature. 6. 120VAC 20 A outlets vs 120VAC 15A outlets. The 20A outlets are different and allow me to use high current power tools, compressors and welders. 7. Price! For the lowest price out of most of the competitors, I have the top performing generator. Thus far I am completely amazed by how quiet the generator is, how it runs a particularly finicky battery charger and the high quality construction. I plan to run this generator for at least a few hundred hours in the first month. I will post an update if anything goes wrong.
Update June 5, 2019 I only have about 44 hours on the unit with one recommended oil change at 20 hours to full synthetic. The unit still starts on one to three pulls but no longer will it power my sliding miter saw nor my 120 VAC compressor. Suddenly the 2200 Watt claim, or even 1800 Watt claim is no longer valid. I have to use my Champion dual fuel generator rated at 3500+ running watts for either or both of these key tools. I am disappointed since this generator originally ran both the saw and the generator. I am going to check with the manufacturer to find out what could cause the issue.
Update: At first there was no reply from support. A day later, I received a support response asking for nameplate information on the compressor and saw that the R2200i would not power.
So the company still supports the generator but slowly. No phone number like Champion. If there is some setting that resolves this issue, then I will get no more than a 3 star rating because the generator has run flawlessly for the many hours I have used it, but has not provided the 2000 watts needed to start the saw and compressor as it specifies it can supply.
Pulled out the manual and warranty information with straightforward, very easy to follow instructions. The mini HOW-TO guide stickered on the front of the control panel may come in handy for my parents. My parents are older and I worry about them figuring out how to operate it so it’s nice to have a reminder on the front in case they need a bit of help.
Oil funnel came with a neat extender to reach into the generator to fill up so there’s no struggle to reach into there. Got the tools and included oil. There’s a fuel gauge on top right next to the opening and a red ring inside that lets you know when the tank is full (nice touch!).
TESTING IT OUT:
After adding oil and gas, it started right up on the FIRST TRY. First thing I noticed was that this generator is incredibly quiet. Naturally, there is still some noise but I was very impressed! I let it run for a few hours to see what it could all handle and to break it in too. I didn’t fill the gas tank, but still used it pretty much all day testing out different items like the fridge, lights, microwave, laptop, hand saw (to name a few) to ensure it could power everything up if the time came. VERY fuel efficient to say the least.
Honestly can’t find anything wrong with this generator. Very quiet. Very fuel efficient, will easily run a refrigerator overnight and your lights, fans, etc. on less than a gallon. Could not resist at this price point, who says you need to spend a thousand bucks! Highly recommended for anyone!
EDIT: Been running this generator for 20 days now, 15 hours a day, with AC, PCs, appliances, TV, etc. I am getting about 10 hours per tankful of gas. Not bad. For this kind of use, check the oil level a couple times a week, and add a little when the dipstick shows low. It only holds a little over a quart of oil, so ONLY add a little oil, check the dipstick, and add more accordingly. It doesn't take much to suddenly overfill it. So far, this unit has been stellar. Hopefully, I will have my electricity line run soon. It IS tedious living off a generator.
