Discover in this review in what situations you can consider the Generac GP3600 and when it is better to turn to other generators.
Generac GP3600 review in short
The Generac GP3600 is budget-friendly but its high THD power is not suited for sensitive electronics.
There are also a decent number of cases where customers have technical issues with this generator.
If you are on a really tight budget, don’t mind the high THD, and don’t like the WEN GN4500 which is better in certain areas, you could consider the Generac GP3600.
That being said, many people will prefer one of the good 4500 watt inverter generators instead.
Pros
- Budget-friendly generator
- Long run time
Cons
- Good number of customers with technical issues
- Loud 4500 watt generator
- High THD power is not suited for sensitive electronics
Some of the best uses for the Generac GP3600 include:
- Powering a variety of devices through your own inverter
- Running machines like certain central air conditioning systems that can handle dirty power
- Running power tools that you don’t mind risking early wear and tear on

What will the Generac GP3600 run?
It is easy to find that the Generac GP3600 offers 4500 starting watts, 3600 running watts, 30 amps, and 120 volts but it is not always clear what devices you can run with this.
You can say a lot about what a 4500 generator will run but there are some shorter general guidelines that can help you get a first impression.
If you only want to run certain bigger devices, it can be helpful to know that the Generac GP3600 could provide enough power for a table saw, 1 HP air compressor, or 1/2 HP furnace fan (separately and you likely still want an inverter).
You can also go a different direction and run multiple small to medium-sized devices with your Generac 7677 GP3600 (again if you have your own inverter).
An example of a combination would be a pressure cooker, vacuum cleaner, blender, and slow cooker.
When in doubt, you can research the power needs of your specific appliances and tools to see whether the Generac GP3600 would be strong enough for these.
Generac GP3600 customer reviews insights
Even if the Generac GP3600 can run what you want and the features look alright, you want to know that some models are not as good as their description implies.
To uncover cases like this, you also want to check the generator reviews of all the customers before you.
At the time of writing, there are a decent number of negative Generac GP3600 reviews.
These negative reviews often involve technical issues that make it so the generator does not work as desired.
Additionally, although this should not be too surprising in an open-frame non-inverter, customers do mention that this generator is relatively loud.
It is worth noting that there are also a nice amount of customers who are happy with the Generac GP3600.
These people are especially positive about being able to generate so much power at a relatively budget-friendly price.
Generac GP3600 alternatives
The Generac GP3600 can be decent if you don’t mind the high THD dirty power and want to keep things budget-friendly.
However, even in this subcategory, you may prefer something like the WEN GN4500 which is similar but more budget-friendly, has a longer run time, and has better fuel efficiency.
Additionally, if you don’t mind investing more in a more reliable generator with clean power, the Westinghouse iGen4500 tends to be a great choice.
Is the Generac GP3600 worth it?
If you are on a really tight budget and don’t mind the dirty power, the Generac GP3600 can still be worth it.
That being said, it is likely worth checking out the WEN GN4500 review since you may prefer this similar generator that is slightly better in a few valuable areas.
Additionally, it is possible that you want to run sensitive electronics and don’t have your own inverter or want a quiet 4500 watt generator.
In these cases, you likely want to save up for an inverter generator anyway since the Generac GP3600 won’t offer you what you want.
