Skeptical? Don't be. This is a great buy.

Reviewed in the United States on November 29, 2023

I couldn't justify the price of the named brand for my needs. I just wanted a small generator that I could take on my sailboat a few times a year to run an AC in hopes the wife would tollerate a few overnights on the coast. After a lot of web searching, youtube research, and review crunching, I decided on this little guy. What a great buy. It is light, quiet, and runs well. It is thoughtfully designed with all the buttons and switches clearly marked and a well engineered gas cap. When I got it, I put in new oil, ran it for the time prescribed, replaced the oil, very little shavings. I bought a little run meter so I could keep up with the hours. I haven't used it on the boat yet, but I've used it a couple of other times. Once to run a power tool, and once on a camping trip with our little camper trailer that doesn't have a generator. It ran the camper AC and lights just fine. A high doller camping trailer next to us had the high dollar named brand generator of the same size. Ours ran just like his, but ours was even quieter. Haha, that felt good. It starts within a few pulls when it's been sitting up for a while, and if I've run it within a few days, it starts first pull. I take it out of the shed to start it every few months just to make sure it will be ready when I need it. I haven't been disappointed yet. Buy it.

Works good

Reviewed in the United States on July 17, 2023

Spark plug was broken but they give you a spare and when you put oil in don't measure the oil out and then pour it all in check the dipstick because there is a little bit of oil already in the motor and you must feel the oil to the full line on the dipstick or the motor will not run it will start and then after about 5 seconds it shuts off once you fill that oil to the full line the motor will continue to run.

Better then I expected!

Reviewed in the United States on May 15, 2024

I bought this generator because im currently housless and needed a source of electricity to be able to go back to school. This generator is better then I had imagined. On 1 gal of gas I can run it for at least 8 hours or longer. It's quiet enough that I am able to have it close enough so it won't get stolen. I especially like that it came with and extra spark plug, a bottle of oil, a funnel for the oil, sparkplug wrench and a screwdriver with both a Phillips and flat head bit. Make sure to change the oil and spark plug after your first run of the generator like they say because my sparkplug did go bad and it didn't want to start up but I changed the sparkplug and it started right up. This thing is also super lightweight and so easy to start so I don't have to have my bf around if I need to turn it on like I have had to have with past generators. I do wish it had an wattage an hour display on it but for this price I'm fine without it.

Never has started- zero stars- update to 4 stars

Reviewed in the United States on February 23, 2023

UPDATE: 10/3/23 We brought this item into the shop and found out there was a missing wire. The guy fixed it for us and didn't charge too much. Since then we have been using it regularly and it is really efficient, pretty quiet and is very lightweight. Was surprised it even runs our saws. It's a shame they don't have better customer service, we could have been using it much sooner.
We purchased this as a backup for our bigger generator. We didn't try it right away but while still within the return window we tried to start it. Followed the directions to a T and even went back through everything to make sure, double and triple checked. It never would start. I was told to contact company who insist I send them a video of me trying to start it. We had already drained oil and gas to ship and this was a ridiculous request as far as I was concerned. I told them exactly what happened when I pulled the chord. They would not respond to emails or phone calls. The return window with Amazon closed and now I have a giant, expensive paperweight. Very disappointed and upset with this purchase.

Genmax 2000i with surprise

Reviewed in the United States on December 23, 2022

The media could not be loaded.

After a long search and comparison, I decided on the Genmax 2000i, which I wanted to take with me to Mexico.

The generator was in Laredo for another week, I picked it up at the bodega, opened the box and checked the generator from the outside, everything was fine, like new, only the adhesive tape on the Kortan was transparent.
When I was in Mexico, I read the instructions, filled up the oil, filled up with petrol and the power generator ran on the third pull and was very quiet. I thought that was a good thing.
Now the assessment:

1: The specified amount of oil did not fit, it should be 1/10 gallon, 0.378 liters, it was too much. The level on the dipstick was exceeded.

2: the big disappointment. The generator does not have an hour meter, so I wanted to install an hour meter, which is very easy to install.
I pulled the spark plug cap and saw a cracked spark plug, not good!!

In various Amazon reviews from various generators I had seen spark plug caps or spark plugs broken, now I had the same thing.
3 years ago I had a Westinghouse igen 2200i from Amazon that had a broken spark plug cap, I bought a cap from Honda which was better and worked fine.
But here the broken spark plug was a bigger problem, picture 2 and 3a

3: the supplied spark plug wrench only worked for a 1/4 turn, then it got stuck. The included spark plug wrench only went on because the spark plug was bent. After changing the spark plug, the original socket wrench can be put on, but it jams.
My assumption, someone had this generator and tried to unscrew the spark plug, bent it and sent the device back. That's why I couldn't fill in 0.378 liters of oil because there was residual oil in it.

4: I was only able to turn the spark plug wrench a 1/4 turn then it stuck to the housing, the spark plug was crooked and porcelain stuck the wrench to the spark plug. I had a hard time getting the spark plug out.

5: Porcelain parts were on the outside of the cylinder head thread, picture 4

6: there was a chip in the spark plug hole thread picture 5, I was able to remove it with tweezers.

7: mmh, did some parts fall through the spark plug thread into the cylinder?
I checked with an endoscope and thankfully didn't find any parts pic 6 but a thread burr on the piston pic 6, using a small 7mm diameter hose on a car vacuum cleaner I went into the spark plug thread and the first time I was able to remove the instep pic 7

8: it was a lot of work to create space for the work picture 8

9: why all this? Look at the pictures 9, 10, 11, and 12, the spark plug can hardly be changed with the long original tool. Even with a short spark plug tool with a 1/4" drive, it is almost impossible to change the plug. A flexible 1/4" or 3/8" socket wrench must be used. The spark plug wrench does not line up with the spark plug.

Summary: It took me 4 hours to fix what someone broke and covered up.
The top thread is slightly damaged, but it should still work.
After taking the whole case apart I can say the plastic parts, the finish everything I saw seems to be of good quality and finish. When assembling it, I noticed that everything was a perfect fit.
The generator has a very low running noise, very quiet in Eco mode.
I was amazed that even in Eco mode the generator runs without any problems with a 1400 watt electric oven.

Would I buy the generator again? Yes, but the supplier has to change the spark core tool immediately, or even better, install an engine that has a spark plug that is slightly slanted to the side, then there will be no problems even with a standard tool.
I hope the seller, wholesaler and manufacturer respond to this comment.
PS: Years before that I worked as a development engineer for electromechanical devices.

Good generator

It’s quiet unit. Has consumption at 50% load is good. Old generator was much louder.
