GENMAX GM9000iED review in short
When it comes to dual fuel inverters of this power level the GENMAX GM9000iED is one of the top options.
At the same time, the number of technical issues GENMAX GM9000iED customers have implies this is not the most reliable generator.
However, many of the dual fuel models on the list of the best 9000 watt generators are not that impressive either.
Your main alternative is the DuroMax XP9000iH which looks a bit more reliable but is not perfect either.
If you don’t mind giving up the dual fuel, you will likely prefer the Champion 201067 9000 over the GENMAX GM9000iED.

- RV or regular camping
- Tailgating
- Small businesses like food trucks

GENMAX GM9000iED customer reviews insights
Looking at the features and price of the GENMAX GM9000iED is a good way to start the review.
However, you want to keep in mind that some generator brands don’t deliver that well on their promises.
You can find out whether this is the case for the GENMAX GM9000iED by looking at the reviews of all the customers before you.
To save you some time and effort, I did this for you and noted down some general tendencies.
The main thing to note is that there are a good number of reviews where customers have technical issues with their GENMAX GM9000iED.
Even when customers are still within the warranty period, they often find it hard to actually get help from support to resolve their issues.
On the one hand, it is fair to say that many of the similar generators also seem to deal with similar issues.
On the other hand, this is still disappointing for a generator like the GENMAX GM9000iED which many people will want to use for home backup power.
GENMAX GM9000iED alternatives
With the number of issues in customer reviews, you likely want to know whether there are any good alternatives to the GENMAX GM9000iED.
When it comes to 9000 watt dual fuel inverters for sale, your main alternative is the DuroMax XP9000iH which seems to be just a bit more reliable, has a longer run time, but also has a higher price.
That being said, this DuroMax XP9000iH is not the best in reliability either.
If you don’t mind giving up the dual fuel feature and a few extra decibels, you can consider the Champion 201067 9000.
This 9000 watt generator seems to be a lot more reliable, has a price that is a lot lower, and is still a great option.
Is the GENMAX GM9000iED worth it?
At this point in the review, you may understand that whether the GENMAX GM9000iED is worth it depends a lot on how much you need the dual fuel feature.
If you really need this, clean inverter power, and 9000 starting watts, you can consider the GENMAX GM9000iED.
At the same time, even with these needs, you may prefer the DuroMax XP9000iH for purposes like backup power since it seems to be just a bit more reliable.
If you don’t necessarily need the option the run on propane, you will likely prefer the Champion 201067 9000.
In turn, the GENMAX GM9000iED would likely not be worth it to you.
