Power & Run Time

The Champion 100573 in use

The Champion 100573

The Champion 100573's design includes a gasoline-fueled 224 cc Champion 4-stroke engine. With a 120V output, it gives a running wattage of 3500W and also a peak wattage of 4000W. Additionally, as the generator is parallel capable (ParaLINK (opens in a new tab) not included), it can be linked to a second unit for more power.

The inverter generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 64 dBA (just slightly more noisy than an office). 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 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel features 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 allowing you to easily charge your batteries. Since a dual port USB adapter is included with the unit, you will also be able to use the DC receptacle to conveniently charge electronics such as mobile phones and tablets.

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

Portability

The design of the Champion 100573 is a typical, open frame, with the dimensions of L23.5 x W24.8 x H20.5 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

The 100573's dry weight of 96.8 lbs lets you use its power anywhere needed. 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

Some light indicators allow you to instantly see if the generator is ready, the generator is overloaded and its oil levels are insufficient.

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

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, 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 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 inverter generators of similar power (between 3000 and 4000 W).

  • Having a dry weight of 96.8 lbs, the Champion 100573 belongs in the expected weight range for inverter generators which produce 3000 to 4000 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM3300i with only 47.4 pounds.
  • When compared to devices able to produce a similar running wattage, this inverter generator and its lowest emitted noise of 64 dBA is on the noisier side. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • The 100573, offering a run time of up to 17 hours with a full tank at a 25% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman W03661OF, which is able to run for up to 25 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption 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 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 inverter 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.
