Zoom on the Generac GP3600
In a nutshell, the Generac GP3600 is a portable generator mostly geared towards:
- RV travellers looking for even more independence
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Generac GP3600's engine, 212 cc Generac OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3600W and reaches a peak wattage of 4500W.
The generator features a simple traditional pull-start mechanism.
The GP3600 can operate for around 9.3 hours at 50% load with a full tank (fuel consumption around 0.4 GPH), due to its fuel capacity of 3.7 gallons.
Since the GP3600 has a somewhat high THD (<25%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
This Generac generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.
The Generac GP3600 has the following dimensions: L24 x W22.5 x H21.3 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.
Although this generator is technically considered 'portable' (in the sense that it can be moved), its 105 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.
The control panel of the GP3600 includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Generac GP3600 also is packed along with the following accessories: tool kit, funnel and oil.
The Generac GP3600 is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, making it usable in forested areas.
The Generac GP3600 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Generac GP3600 compare to generators of similar power (between 3500 and 4500 W).
- With a dry weight of 105 pounds, the Generac GP3600 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- Autonomy-wise, with around 9.3 hours on a full tank at a 50% load, the GP3600 is on the low end when compared to other generators of a similar power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.4 GPH (gallon per hour) at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Generac GP3600 is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
The bottom line
- Several accessories included
- Decent weight (105 lbs)
