In summary, the Champion 75531i is a quiet and compact portable inverter generator especially useful for:

  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • Camping and tailgating hobbyists looking for a portable power source
  • RV travellers wishing to enhance their freedom and nomad lifestyle

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's design includes a gasoline-fueled 171 cc Champion 4-stroke engine. With a 120V output, it gives a running wattage of 2800W and also a peak wattage of 3100W.

With a noise rating of 58 dBA (less noisy than rainfall), the inverter generator features a simple traditional 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).

The 75531i generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel includes the following 3 AC outlets:

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

It also sports 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Champion generator is RV Ready.

Portability

Since the Champion 75531i is an inverter generator, its closed design (L22.4 x W17.3 x H18.3 in) has an esthetical advantage over conventional, open frame devices. The design follows the contemporary trends and is perfect for recreationally generating power.

As the 75531i's weight is only 83.8 lbs, it can follow you and your power needs anywhere. Additionally, it can be easily moved with the help of its set of 2 wheels (⌀5.5") and its folding handle, once it is on the ground.

Features

Panel of the Champion 75531i

The 75531i's control panel

Some light indicators allow you to instantly see if the oil level is too low, the generator is ready and the generator is on overload.

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

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Champion 75531i's package also includes these accessories: battery charging cables, tool kit and funnel.

Emissions

The Champion 75531i is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all 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).

  • Regarding its weight, the Champion 75531i only weighs in at 83.8 pounds, which means it's one of the lighter generators in the 2500-3500 rated wattage range. If weight matters to you, one of the champions in this power range is the Generac GP3300i with only 59.5 pounds.
  • Since this inverter generator is rated for a lowest possible noise of 58 dBA, it can be considered as one of the more quiet of the products generating similar power. If noise emissions are one of your priorities, you may be interested in the Honda EU3000iS, one of the least noisy generators similarly powerful as this one, rated for 50 dBA.
  • Autonomy-wise, with up to 8 hours on a full tank at a 25% load, the 75531i is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 200954, as it provides up to 22 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Compared to its peers, this inverter generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.2 GPH at a 25% load. If you wish to further improve in the area of fuel efficiency, the Energizer eZV3500P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.

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

Price comparison

As you can see from this interactive chart, when compared to other 2500-3500W generators, the Champion 75531i is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
