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 outdoor fairs, festivals or events
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Camping and tailgating hobbyists looking for a portable power source

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

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. 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 is rated for a noise of 64 dBA (just slightly more noisy than a normal conversation). Its starting mechanisms include a conventional 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).

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.

As the 100573 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD), sensitive electronics may be plugged in the AC outlets safely.

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 allowing you to easily charge your batteries.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Champion generator is RV Ready.

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 design is ideal for rough environments and demanding outdoor use.

The 96.8 lbs of the 100573's dry weight enables you to use it anywhere you will ever need. 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

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

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Champion 100573 also comes with several accessories, including: 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, so it is adequate 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).

  • At a weight of 96.8 pounds, the Champion 100573 places in the expected weight range of the generators in the 3000-4000 rated wattage range. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • 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.
  • The 100573, falls within the average autonomy range compared to generators of a roughly same power, with a run time of up to 17 hours at a 25% load and a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Champion 200954, boasting with up to 22 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. At an estimated fuel consumption of 0.17 GPH (gallon per hour) at 25% load, this inverter generator is a rather fuel efficient one within its wattage category. 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.
