Zoom on the Champion 100573

In a nutshell, the Champion 100573 is a portable inverter generator mostly geared towards:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • 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 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. In addition, as it is parallel capable (ParaLINK (opens in a new tab) not included), this power can be increased when linked to another similar or 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).

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.

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

Outlets

The control panel features the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

In addition, it provides 1 DC outlet: there's a 12V 8A receptacle with which you may charge your batteries with ease. 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 Champion 100573 has the following dimensions: L23.5 x W24.8 x H20.5 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

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

The light indicators show you if the generator is ready, the generator is on overload and the oil level is too low.

From a security point of view, the generator is equipped with an automatic low oil shut-off, giving you a peace of mind during use.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Champion 100573 also comes with some accessories: key fob, funnel and dual port USB adapter are included.

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).

  • Having a dry weight of 96.8 lbs, the Champion 100573 belongs in the expected weight range for generators which produce 3000 to 4000 rated watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM3300i, with a dry weight of only 47.4 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 noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 51 dBA.
  • Since the 100573 boasts with a run time of up to 17 hours at 25% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Champion 200914, reaching up to 22 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 can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.17 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.

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.
