Power & Run Time

The Champion 100573 in use

The Champion 100573

The Champion 100573 is powered by a 224 cc Champion 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as 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.

The inverter generator is rated for a noise of 64 dBA (just slightly more noisy than an office). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). Moreover, to offer you even more convenience, the 100573 can also be remotely started (key fob included).

With a full tank, the 100573 can operate for up to 17 hours (fuel consumption around 0.17 GPH), thanks 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 features the upcoming 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.

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

Portability

The Champion 100573 has a conventional, open frame design, of the following dimensions: L23.5 x W24.8 x H20.5 in, which offers support and allows it 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. Moreover, once it’s on the ground, its wheel kit (⌀8") and its folding handle will allow you to shift it without effort.

Features

Panel of the Champion 100573

The 100573's control panel

When its oil levels are insufficient, the generator is ready and the generator is overloaded, you will be informed by the featured light indicators.

From a security standpoint, the product offers an automatic low oil shut-off, allowing you to use it with a peace of mind.

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: funnel, key fob and dual port USB adapter.

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 and thus, may be used 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).

  • In terms of its dry weight, the Champion 100573 stands at only 96.8 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.
  • The inverter generator can be considered average in its noise for its power category, as it is rated at 64 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
  • With a run time of up to 17 hours at 25% load, the 100573 has one of the higher run times, compared to its similarly powerful peers. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Champion 100892, as it provides 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 fuel consumption is your top priority, we suggest to check out the Energizer eZV3500P, which has a fuel consumption of only 0.13 GPH and thus, is one of the most efficient devices in our database.

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.
