Zoom on the Champion 100574

In a nutshell, the Champion 100574 is a compact portable inverter generator mostly geared towards:

  • 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
  • Camping and tailgating hobbyists looking for a portable power source

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

Thanks to its dual-fuel technology, the Champion 100574 delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3500W and a peak wattage of 4000W. When propane-powered, it has 3150 rated watts and 3600 peak watts. In addition, as it is parallel capable (ParaLINK (opens in a new tab) not included), this power can be doubled when linked to another similar or 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.

As for its running time, the 100574, along with its 2.9 gallons fuel capacity, can run for up to 14.5 hours with a full tank filled with gasoline (fuel consumption around 0.2 GPH). If propane is used, it can operate for up to 12 hours (on a 20 lbs tank - propane consumption around 0.39 GPH).

The 100574 produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the following 3 AC outlets:

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

Additionally, it features 1 DC outlet: there's a 12V 8A (cigarette lighter style) 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

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 generator is designed for ideal use outdoors and in rough 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.

Features

Panel of the Champion 100574

The 100574's control panel

Several light indicators serve to show you when the generator is overloaded, the oil level is too low and the generator is ready.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Champion 100574 also is packed along with the following accessories: propane hose, battery charging cables, funnel and dual port USB adapter.

Emissions

The Champion 100574 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 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).

  • As for its weight, the Champion 100574 weighs only 82.2 pounds, making it one of the lighter generators in the 3000-4000 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.
  • The inverter generator can be considered average in its noise for its power category, as it is rated at 64 dBA. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
  • Given that the 100574 reaches an autonomy of up to 14.5 hours with a full tank and at 25% load, it is placed within the average autonomy range of similarly powerful generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Energizer eZG3500, reaching up to 19.5 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 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 wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.14 GPH, may be the right generator for you.

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.
