What will the Westinghouse iGen2500 run?
The two main questions when considering the Westinghouse iGen2500 are whether it offers enough power for your needs and whether you want the option to run on propane too.
We have a more in-depth device chart for 2500 watt generators but the few examples in this review can already be helpful too.
Some of the bigger appliances and tools the Westinghouse iGen2500 should be able to run are a 10k BTU window air conditioner, certain circular saws, and certain bench grinders.
You can also use your generator to run multiple smaller appliances and tools.
One example of a combination the Westinghouse iGen2500 should be able to run is a refrigerator, coffee maker, laptop, and electric drill.
Keep in mind that you likely need to pay attention to the startup sequence to run these devices.
Additionally, the Westinghouse iGen2500 is typically not strong enough to run bigger machines like a 13,500 BTU air conditioning system or welder.
Westinghouse iGen2500 customer reviews insights
Even if a generator like the Westinghouse iGen2500 looks good in terms of features and price, you want to check the customer reviews to make sure it does not have too many problems.
This is because there are enough examples of generators where there is a high rate of technical issues or an inconvenient design.
At first sight, the Westinghouse iGen2500 reviews may just look solid but not exceptionally good.
However, besides a few exceptional technical problems many of these suboptimal Westinghouse iGen2500 reviews mention that it is too loud or heavy.
At this decibel level and weight, it seems this is more due to optimistic expectations instead of the Westinghouse iGen2500.
Even fewer cases of technical problems are of course welcome but it will be hard to find 2500 watt inverter generators that do this better than the Westinghouse.
Westinghouse iGen2500 alternatives
The two main reasons you would be interested in Westinghouse iGen2500 alternatives are that you want the option to run on propane too and/or need more power.
For this first need, you can consider the WEN DF250i which looks like a solid 2500 watt dual fuel inverter although more customer reviews would be welcome.
If you need more power, you can consider the Westinghouse iGen4500 which offers as its name implies 4500 starting watts.
This Westinghouse iGen4500 also has a dual fuel version if you want to run on propane and need more power.
Is the Westinghouse iGen2500 worth it?
The Westinghouse iGen2500 is not only the best price value generator of this power level but also just the best in many of the important performance areas.
In simpler words, if you want a 2500 watt gasoline inverter generator, this model from Westinghouse is likely worth it for you.
Two things you do want to keep in mind are that some individuals will prefer the dual fuel flexibility and that some people will need more than 2500 starting watts.
If these things apply to you, you can check out the Westinghouse iGen2500 alternatives mentioned in this review.
