Generac GP1800 Spec Review

Description

Zoom on the Generac GP1800

In a nutshell, the Generac GP1800 is a compact portable generator mostly geared towards:

• Camping and tailgating hobbyists looking for a portable power source
• DIYers who wish to improve their efficiency with tools

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Generac GP1800

The Generac GP1800 is powered by a 163 cc Generac OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 1800W as well as a peak wattage of 2050W.

Its starting mechanism is based on a conventional pull-start mechanism.

Thanks to a fuel capacity of 3.5 gallons, the GP1800 can operate for around 10.5 hours at 50% load with a full tank (fuel consumption around 0.33 GPH).

The quite high THD (<25%) of the GP1800 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

Portability

The Generac GP1800 has a conventional, open frame design, of the following dimensions: L22.8 x W16.8 x H17.3 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

The 84 lbs of the GP1800's dry weight enables you to use it anywhere you will ever need. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

The GP1800's control panel

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Generac also included a funnel in the GP1800's packaging.

Emissions

The Generac GP1800 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, which makes it suitable for use in forested areas.

The Generac GP1800 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Generac GP1800 compare to generators of similar power (between 1500 and 2500 W).

• At a dry weight of 84 pounds, the Generac GP1800 is one of the heavier devices which can produce between 1500 and 2500 running watts. In terms of weight, one of the champions in their power range is the Champion 200949, standing at just 38.6 lbs.
• With a run time of around 10.5 hours at 50% load, the GP1800 has one of the higher run times, compared to its similarly powerful peers. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Westinghouse WGen2000, with around 20 hours.
• The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.33 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen2200. With a fuel consumption of as little as 0.12 GPH, it is one of the most efficient generators currently on the market.

Price comparison

The bottom line

Unlike many websites, we did our best to research each of the specs above. That being said, we are not immune to making the occasional mistake or omission. Should you notice any missing or incorrect values, don't hesitate to suggest improvements so we can address the issue.
