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
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • 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 information.

Power & Run Time

The Champion 100573 in use

The Champion 100573

The Champion 100573's engine, 224 cc Champion 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 3500W and reaches a peak wattage of 4000W. 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.

With a noise rating of 64 dBA (just slightly more noisy than a normal conversation), the inverter generator features a conventional pull-start mechanism, but also a simple and elegant electric starter (battery included). For additional convenience, the 100573 may also be remotely started (key fob included).

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

The 100573 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 includes 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 receptacle with which charging your batteries is made easy.

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Champion generator is RV Ready.

Portability

With its dimensions of L23.5 x W24.8 x H20.5 in, the conventional, open frame design of the Champion 100573 offers stability and allows the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

As the 100573's weight is only 96.8 lbs, it can follow you and your power needs anywhere. In addition, with its wheel kit (⌀8") and its folding handle, it may be shifted with ease, once placed on the floor.

Features

Panel of the Champion 100573

The 100573's control panel

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

Security-wise, this product benefits from an automatic low oil shut-off, which gives you a complete peace of mind when using it.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 100573, the following accessories are also included: dual port USB adapter, key fob and funnel.

Emissions

The Champion 100573 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 and thus, may be used in forested areas.

Product Video

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 far as its dry weight is concerned, the Champion 100573 weighs just 96.8 pounds and thus, it is one of the lighter 3000 to 4000 rated wattage generators. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 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 you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • Offering up to 17 hours of running time on a full tank at 25% load, the 100573 is 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 Champion 200954, reaching up to 22 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. With an estimated gasoline consumption of 0.17 GPH (gallon per hour) at 25% load, this inverter generator is among the more fuel efficient of the products in the above-mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3500P, with a fuel consumption of 0.13 GPH could be in your good books.

Price comparison

As you can see from this interactive 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.
