Power & Run Time

The Champion 100573 in use

The Champion 100573

The Champion 100573's core is the 224 cc Champion 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 3500W and 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 background music). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included). The 100573 can also be remotely started, offering further convenience (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

It also sports 1 DC outlet: there's a 12V 8A receptacle with which charging your batteries is made easy.

With its TT-30R receptacle (TT as in '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 design is ideal for rough environments and demanding outdoor use.

The 100573 can be taken anywhere with you, thanks to its weight of 96.8 lbs. Furthermore, once placed on the floor, effortless displacement is possible thanks to its wheel kit (⌀8") and its folding handle.

Features

Panel of the Champion 100573

The 100573's control panel

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

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

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Champion 100573's package also includes these accessories: funnel, key fob and dual port USB adapter.

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, making it usable 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 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.
  • This inverter generator has a somewhat average expected noise for its power range, rated at 64 dBA. 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.
  • The 100573 provides a higher run time than similarly powerful devices, reaching up to 17 hours at 25% load. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Champion 200954, which is able to run for up to 22 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.17 GPH (gallon per hour) at 25% load. If you wish to further improve in the area of fuel efficiency, the Energizer eZV3500P, which boasts with a gas consumption of only 0.13 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 100573 is on the average side of the price range.

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