DuroMax XP4500iH review in short
The DuroMax XP4500iH is an alright generator for people who want to camp, tailgate, run power tools, or power their food truck on two fuel types.
However, due to the number of negative customer reviews and somewhat higher price, this DuroMax is not on the list of the best 4500 watt generators.
You will likely prefer dual fuel generators like the Champion 200988 4500 or Westinghouse iGen4500DF instead.
Pros

- Dual fuel option flexibility
- Good performance tracking screen
- Remote generator operation
- Long run time
- Solid warranty durations
Cons

- Pricey compared to generators of similar power levels
- Relatively loud for this power level
- Customer support has room for improvement
Some of the best uses for the DuroMax XP4500iH include:
- RV or regular camping
- Small businesses like food trucks
- Tailgating
- Running certain power tools

What will the DuroMax XP4500iH run?
One of the most important details to look at is whether a generator offers enough power to run what you want to run.
Similar to what other 4500 watt generators can run, the DuroMax XP4500iH will generally be able to run devices like a window air conditioner (15,000 BTU), a table saw, or a 1 HP air compressor separately.
You can also choose to run multiple small to medium electrical appliances and tools at the same time instead.
With the right adapters, you could even make the DuroMax XP4500iH run a house with a limited amount of electrical devices.
These general principles can be helpful but ideally, you would also do more specific calculations for your situation.
With the starting and running watts of the DuroMax XP4500iH and the power consumption of the devices, you can see exactly how much you can actually run.
DuroMax XP4500iH customer reviews insights
Seeing the features of the DuroMax XP4500iH on paper is a helpful start.
However, you also want to know that generator brands do not always deliver perfectly on these promises.
The customer reviews of the DuroMax XP4500iH are a great place to find these unexpected disadvantages.
To save you some time and effort, I did this for you and noted some general tendencies.
There are still customers who are happy with their DuroMax XP4500iH but there are also a decent amount of early technical issues.
These issues vary in their natures but the main conclusion is that the DuroMax XP4500iH does not look like the most reliable generator.
Additionally, the customers that mention anything about this in their reviews find the customer support suboptimal.
DuroMax XP4500iH alternatives
Even though the DuroMax XP4500iH is not optimal, you may still have a need for a good (dual fuel) 4500 watt generator or comparable products.
In this power category, your two main alternatives will be the Champion 200988 4500 (dual fuel), Westinghouse iGen4500 (gasoline), and Westinghouse iGen4500DF (dual fuel).
Is the DuroMax XP4500iH worth it?
If you would really need a 4500 watt dual fuel inverter generator and there are no other models available, the DuroMax XP4500iH could be worth the benefits.
At the same time, there are just a few too many reviews where customers got a suboptimal generator. Especially at the somewhat higher price.
Because of the suboptimal reliability reputation, you will likely prefer one of the other good similar DuroMax XP4500iH alternatives available.
Especially for situations like home backup power where you really want your generator to function properly.
