What can the DuroMax XP9000iH run?
Some of the bigger devices the DuroMax XP9000iH can typically run are a clothes dryer, a 3-ton central air, or a hot water heater.
Additionally, it is also possible that you want to run multiple appliances and tools together.
With the 7600/7200 (gasoline/propane) running watts of the DuroMax XP9000iH, you can do this too.
To be precise about this you want to follow the steps in the article about what 9000 watt generators will run.
That being said, one example of a combination the DuroMax XP9000iH should be able to run is a 2-ton central air, air compressor, laptop, toaster, and electric grill.
Keep in mind that the starting sequence of these devices matters and that you still need to follow generator safety guidelines.
Are the customer reviews of the DuroMax XP9000iH positive?
The customer reviews of the DuroMax XP9000iH are relatively positive but there are some negative experiences too.
It is important to keep in mind that you want to check the customer reviews of generators. Even if they look great on paper.
This is because there are examples where generators actually come with technical issues and unexpected downsides.
There are a decent number of cases where customers either got a faulty generator or that the DuroMax XP9000iH stopped functioning as desired relatively soon.
These customers also mention that it is hard to actually get help from support. Even within the warranty period.
It is hard to find 9000 watt dual fuel inverter generators that do this better but at the same time, the DuroMax XP9000iH still has room for improvement in terms of quality.
What are the alternatives to DuroMax XP9000iH?
The main alternatives to the DuroMax XP9000iH are the Champion 201067 9000, the GENMAX GM9000iE, and the Predator 9500.
If you don’t necessarily need the dual fuel feature, the Champion 201067 9000 can be a good alternative to the DuroMax 9000 inverter generator.
This Champion generator is a bit louder but also a lot more reliable and budget-friendly.
There is also the GENMAX GM9000iE which is a quieter 9000 watt generator but also one that is even less reliable than the DuroMax XP9000iH.
You may also prefer the Predator 9500 over the DuroMax XP9000iH depending on details like your fuel preferences and how much you like the DuroMax brand.
Unfortunately, there are not many good options when it comes to dual fuel inverter generators of this power level.
You could consider putting two less powerful but more reliable dual fuel generators in parallel but this will generally take up more space and be less convenient to operate.
Is the DuroMax XP9000iH worth it?
Yes, the DuroMax XP9000iH can be worth it for situations like an RV camping trip where you want to generate a lot of power from propane and don’t need the most reliability.
To decide whether the DuroMax XP9000iH is a good choice you want to think about how much you value the dual fuel feature and/or the convenience of having a single generator.
For something like home backup power where reliability is important, the DuroMax XP9000iH may not be worth it due to the number of technical issues.
On the other hand, if you want a 9000 watt dual fuel inverter for something like a camping trip or food truck, the DuroMax XP9000iH could potentially be a good choice.
Keep in mind that you could also consider putting two smaller dual fuel generators in parallel although this also has its downsides.
