Zoom on the Champion 100573

In a nutshell, the Champion 100573 is a portable inverter generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go

In the following paragraphs, we shall explore the power characteristics, available outlets, portability and any additional features of the device, along with its emission compliance parameters.

Power & Run Time

The Champion 100573 in use

The Champion 100573

The Champion 100573 houses a 224 cc Champion 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 3500W along with a peak wattage of 4000W. In addition, as it is parallel capable (ParaLINK not included), this power can be doubled when linked to another similar or compatible unit.

At a noise rating of 64 dBA (just slightly more noisy than an office), this inverter generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included). To add further convenience, the 100573 can be remotely started (key fob included).

Thanks to a fuel capacity of 2.9 gallons, the 100573 can operate for up to 17 hours with a full tank (fuel consumption around 0.17 GPH).

The 100573 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

The following are examples of possible devices which the generator will allow you to power simultaneously:Note: Not all of these items may be able to start at the same time. These examples are based on a maximum load of 75 % and on wattage estimates. Use our wattage calculator to find out if this product will be suitable for your needs.

Outlets

The control panel includes 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 receptacle allowing you to easily charge your batteries.

This Champion generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The dimensions of the Champion 100573, which are L23.5 x W24.8 x H20.5 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 100573 can be taken anywhere with you, thanks to its weight of 96.8 lbs. In addition, with a wheel kit (⌀8") and a folding handle, it may be displaced with ease, once placed the floor.

Features

Several light indicators serve to show you when the generator is on overload, its oil levels are insufficient 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.

Apart from the typical documentation and a user manual, which lets you start it right away, the Champion 100573 also is packed along with the following accessories: funnel, dual port USB adapter and key fob.

Emissions

The Champion 100573 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 100573 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100573 compare to generators of similar power (between 3000 and 4000 W).

  • As for its weight, the Champion 100573 weighs only 96.8 pounds, making it one of the lighter generators in the 3000-4000 rated wattage category. If weight is your top priority, one of the champions in this power category is the Generac GP3500iO, weighing just 74.3 pounds.
  • Because this inverter generator emits noise as low as 64 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • Since the 100573 boasts with a run time of 17 hours at 25% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Energizer eZG3500, reaching 19.5 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. At an estimated fuel consumption 0.17 GPH (gallon per hour) at 25% load, this inverter generator is a rather fuel efficient one within its wattage category. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.14 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this dynamic chart, when compared to other 3000-4000W generators, the Champion 100573 is on the average side of the price range.

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