What can the WEN 4500 generator run?
Even with the number of watts, amps, and volts, it is not always straightforward to know the actual device combinations the WEN 4500 generator can run.
Some of the bigger machines this generator can run individually include a window air conditioner (15,000 BTU), a table saw, or a 1 HP air compressor.
You can also divide the 4500 starting watts and 3500 running watts over multiple devices.
An example of a combination the WEN 4500 generator should be able to run is a refrigerator, coffee maker, flat screen TV, and dishwasher.
Even better than these examples is looking up the power needs of the devices you want to run and figuring out whether these fit in the power capacity of a 4500 watt generator.
WEN 4500 generator customer reviews insights
Similar to other products, generators are not always good as their features suggest.
To make sure the WEN 4500 inverter generator is high-quality, you also want to take a look at the reviews of the customers before you.
While these are positive for now, the WEN 56455i unfortunately does not have that many customer reviews at the time of writing.
One thing that is worth mentioning is that customers tend to be relatively positive about other generators from the WEN brand.
This does not tell you how long the WEN 4500 will last but does give some peace of mind.
WEN 4500 generator alternatives
The WEN 4500 generator can be a good choice but you may also want to know about other inverters that have more customers and/or stand out in other areas.
If you want a high-quality 4500 watt inverter with more customer reviews, a quieter rating, and still a reasonable price, the Westinghouse iGen4500 could be the right choice for you.
You can also consider the Champion 200988 4500 DF which is pricier and slightly louder but also dual fuel and better in terms of reliability reputation.
Is the WEN 4500 generator worth it?
If you don’t mind the small number of customer reviews and the short commercial warranty, the WEN 4500 inverter generator can definitely be worth the investment.
This is one of your best bets if you want to run small to medium electronics at a relatively budget-friendly price.
While these things still apply, it is worth mentioning that there are also alternatives to the WEN 4500 generator that are better in terms of the amount of reviews, noise levels, and/or reliability.
