Zoom on the Champion 75531i
In summary, the Champion 75531i is a quiet and compact portable inverter generator especially useful for:
- Amateur DIY lovers
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Camping and tailgating hobbyists looking for a portable power source
- RV travellers who wish to upgrade their experience to another level
Power & Run Time
The Champion 75531i's core is the 171 cc Champion 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 2800W and a peak wattage of 3100W.
The inverter generator is rated for a noise of 58 dBA (less noisy than a conversation at home). Its starting mechanism is based on 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).
The 75531i generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.
The control panel includes the following 3 AC outlets:
In addition, it provides 1 DC outlet: there's a 12V 8A receptacle allowing you to easily charge your batteries.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Champion generator is RV Ready.
The Champion 75531i's characteristic encased inverter generator design (L22.4 x W17.3 x H18.3 in), provides an esthetical advantage over any ordinary, open frame product. This modern design aims to provide an ideal power solution to recreational users.
With a dry weight of 83.8 lbs, the 75531i can easily follow you wherever your power needs are. Moreover, a wheel kit (⌀5.5") and a folding handle allows you to effortlessly displace it once it's on the ground.
Several light indicators serve to show you when its oil levels are insufficient, the generator is on overload and the generator is ready.
As for its security measures, the device features an automatic low oil shut-off, letting you use it with a peace of mind.
With the basic documentation and a user manual, letting you start the generator quickly, the Champion 75531i also comes with several accessories, including: funnel, battery charging cables and tool kit.
The Champion 75531i is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor, which makes it suitable 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 weigh, the Champion 75531i stands at only 83.8 lbs, meaning that is one of the one of the lighter devices of the 2500-3500 rated wattage category If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 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. 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.
- As far as autonomy is concerned, providing up to 8 hours of runtime with a full tank at a 25% load, the 75531i falls into the low end in comparison with other devices of a comparable power output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EU3000iS, reaching up to 20 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. This inverter generator has an average fuel consumption among comparably powerful devices, as it reaches 0.2 GPH (gallon per hour) at a 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3200P is a device you should look out for.
Here's a list of the most popular specific comparisons:
As you can see from this dynamic 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.
The bottom line

- Several accessories included
- RV Ready
- Lightweight for its kind (83.8 lbs)
- Quiet for its power (58 dBA)
- Decent fuel efficiency
- No data center
- No electric start
- Relatively low run time
