Find out in this GENMAX 9000 GM9000iE review whether this inverter generator is the right choice for you and what alternatives there are.
GENMAX 9000 review in short
On paper, the GENMAX 9000 GM9000iE looks like a nice quiet 9000 watt generator.
However, with how common technical issues are, you likely want to turn to other good 9000 watt generators instead.
For example, you will likely prefer the Champion 201067 9000 over the GENMAX 9000 if you don’t mind a few decibels more.
Additionally, you can put two smaller but more reliable generators in parallel.
There will still be some cases where the GENMAX 9000 GM9000iE is the right choice but these will likely be the exceptions.
Pros
- Very quiet for this power level
- Nice run time
- Has a 50 amp outlet
- Remote generator operation
Cons
- Technical issues are somewhat common
- Short warranty
- Hard to get help from customer support
- Somewhat pricey
- Heavy weight can be challenging to move around
- Not that fuel-efficient
Some of the best uses for the GENMAX 9000 include:
- Camping
- RV’s
- Construction sites
- Tailgating
- Small businesses like food trucks
- Running certain power tools
- Theoretically home backup power but the GENMAX 9000 does not look reliable enough for this

What will the GENMAX 9000 run?
It is easy to see that the GENMAX 9000 GM9000iE has 9000 starting watts, 7600 running watts, 240 volts, and a 50 amp outlet.
However, what these details mean in terms of devices you can run is not always clear.
There is more to say about what a 9000 watt generator can run but a few quick notes can help you get an idea of whether the GENMAX 9000 GM9000iE offers the right amount of power.
When it comes to running individual devices, the GENMAX 9000 GM9000iE should be able to run most of the things you can find besides maybe a few really big machines.
For example, this inverter generator should have no issues with running things like a 3-ton central air or a clothes dryer.
That being said, you would likely also want to run multiple devices with your GENMAX 9000 GM9000iE.
You would preferably do the calculations for your specific devices but one combination you should be able to run is a coffee maker, 2-ton central air, refrigerator, circular saw, and toaster.
Keep in mind that you may need to implement a certain start-up sequence, that device brand power needs can vary, and that you still want to implement generator safety guidelines.
GENMAX 9000 customer reviews insights
If you would only look at the features in this review, the GENMAX 9000 GM9000iE would look promising.
However, you want to keep in mind that the generators customers actually get can sometimes have technical or convenience issues that are not in the features.
This is actually the case for the GENMAX 9000 GM9000iE to a relatively large extent.
While there are happy customers too, there are also a good amount of reviews where the GENMAX 9000 GM9000iE does not perform (as desired).
The exact technical issues in these reviews vary but the main conclusion is that the customers are not really able to use the GENMAX 9000 GM9000iE.
On top of that, it seems to be really hard to actually get help from GENMAX customer support. Even when customers are still within the warranty duration.
In short, it looks like the GENMAX 9000 GM9000iE is not that reliable which is especially suboptimal for purposes like home backup power.
GENMAX 9000 alternatives
With the technical issues in the customer reviews it is only normal to search for alternatives to the GENMAX 9000.
Your best bet when it comes to similar generators is the Champion 201067 9000.
This 9000 watt generator is louder than the GENMAX 9000 but its reliable performance and the more budget-friendly price will often be worth this.
Another option is running two less powerful but more reliable generators in parallel to get similar amounts of watts.
You can also check out the GENMAX GM9000iED review if you are interested in a strong dual fuel inverter instead but keep in mind that this model also has its issues.
Additionally, the GENMAX 9000 vs Predator 9500 comparison can be an interesting read too.
Is the GENMAX 9000 worth it?
As this review should make clear, the GENMAX 9000 GM9000iE is not the most reliable inverter generator out there.
It is possible that there are some people who just want the quietest 9000 watt generator they can get and don’t mind the possibility of technical issues.
However, if you don’t mind the extra decibels you will likely prefer the Champion 201067 9000 which would make the GENMAX 9000 GM9000iE not worth it.
Another option is running two smaller but higher-quality generators in parallel to get similar amounts of watts.
In short, while there are exceptions, many people will prefer other options over the GENMAX 9000 generator.
