Zoom on the Champion 100574

In summary, the Champion 100574 is a compact portable inverter generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • 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
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

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 100574 in use

The Champion 100574

The dual-fuel technology of the Champion 100574 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3500W and a starting wattage of 4000W. If propane-powered, it gives 3150 rated watts and 3600 starting watts. Moreover, since it is parallel capable (ParaLINK (opens in a new tab) not included), its power may be doubled if linked to a second compatible unit.

The inverter generator is rated for a noise of 64 dBA (just slightly more noisy than a normal conversation). Its starting mechanism is based on a simple traditional pull-start mechanism.

The 100574, with a fuel capacity of 2.9 gallons, reaches a run time of up to 17 hours utilizing gasoline (fuel consumption around 0.17 GPH). Alternatively, it can reach a run time of up to 18 hours (on a 20 lbs tank - propane consumption around 0.26 GPH) with propane.

The 100574 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 features the following 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 (cigarette lighter style) receptacle with which you may charge your batteries with ease.

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

Portability

The dimensions of the Champion 100574, which are L20.5 x W18.3 x H18.9 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

The 82.2 lbs of the 100574's dry weight enables you to use it anywhere you will ever need. Additionally, the generator’s mobility is also improved by its open frame design, as it can be easily grabbed and shifted.

If you wish to transport the 100574 more easily, you may also consider purchasing the official wheel kit (opens in a new tab).

Features

Panel of the Champion 100574

The 100574's control panel

Some light indicators allow you to instantly see if the generator is ready, its oil levels are insufficient and the generator is overloaded.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 100574, the following accessories are also included: propane hose, battery charging cables, dual port USB adapter and funnel.

Emissions

The Champion 100574 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, which makes it suitable for use in forested areas.

The Champion 100574 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100574 compare to generators of similar power (between 3000 and 4000 W).

  • In terms of its dry weight, the Champion 100574 stands at only 82.2 lbs, meaning that is one of the lighter devices of the 3000-4000 rated wattage category Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • As this inverter generator can emit noise as low as 64 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are one of your priorities, you may be interested in the Cat INV4000E, one of the least noisy generators similarly powerful as this one, rated for 51 dBA.
  • Offering up to 17 hours of running time on a full tank at 25% load, the 100574 is within the average autonomy range of similarly powerful generators. 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 Champion 200954, with 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. This inverter generator, with an estimated fuel consumption of just 0.17 GPH (gallon per hour) at 25% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Energizer eZV3500P. With a fuel consumption of as little as 0.13 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Champion 100574 is on the average side of the price range.

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