  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Champion 75531i in use

The Champion 75531i

The Champion 75531i is powered by a 171 cc Champion 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 2800W as well as a peak wattage of 3100W.

With a noise rating of 58 dBA (less noisy than a refrigerator), the inverter generator features a conventional pull-start mechanism.

The fuel capacity of 1.6 gallon allows the 75531i to operate for up to 8 hours with a full tank (fuel consumption around 0.2 GPH).

Sensitive electronics can be safely plugged in the AC outlets, as the 75531i produces a clean sine wave, with a <3% Total Harmonic Disruption (THD).

Outlets

The control panel provides the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

In addition, it provides 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease.

This Champion generator is RV Ready, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

As the Champion 75531i is an inverter generator, its encased design (L22.4 x W17.3 x H18.3 in) offers more aesthetics than a conventional, open frame product. The generator has a contemporary design, convenient for recreationally generating power.

With a dry weight of 83.8 lbs, the 75531i can easily follow you wherever your power needs are. Moreover, its wheel kit (⌀5.5") and its folding handle will allow you to effortlessly shift it once it's on the ground.

Features

The 75531i's control panel

When the oil level is too low, the generator is ready and the generator is overloaded, you will be informed by the featured light indicators.

From a security standpoint, the product offers an automatic low oil shut-off, allowing you to use it with a peace of mind.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 75531i, the following accessories are also included: funnel, tool kit and battery charging cables.

Emissions

The Champion 75531i is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use in forested areas.

The Champion 75531i versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 75531i compare to generators of similar power (between 2500 and 3500 W).

  • In terms of its dry weight, the Champion 75531i stands at only 83.8 lbs, meaning that is one of the lighter devices of the 2500-3500 rated wattage category In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • With a lowest noise rating of 58 dBA, the inverter generator is one of the more quiet of the generators of similar power. For those who are looking for a less noisy device, we suggest the Honda EU3000iS. With just 50 dBA, it is one of the most quiet devices in this power range.
  • Regarding its autonomy, the autonomy of the 75531i, reaching up to 8 hours at a 25% load, can be considered as low end, compared to other products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EU3000iS, boasting with up to 20 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. As this inverter generator uses an estimated 0.2 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3200P, with a fuel consumption of 0.13 GPH could be in your good books.

Here's a list of the most popular specific comparisons:
