Description

Zoom on the Champion 100558

In a nutshell, the Champion 100558 is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Champion 100558 in use

The Champion 100558

The Champion 100558's design includes a gasoline-fueled 208 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 3500W and also a peak wattage of 4375W.

The generator is rated for a noise of 68 dBA (less noisy than an office). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included). To add further convenience, the 100558 can be remotely started (key fob included).

The fuel capacity of 4.7 gallons allows the 100558 to operate for around 12 hours at 50% load with a full tank (fuel consumption around 0.39 GPH).

Outlets

The control panel features the following 4 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (L5-30R) receptacle
120V 30A (TT-30R) receptacle

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

Portability

The Champion 100558 has a conventional, open frame design, of the following dimensions: L24.9 x W22.9 x H22.4 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 118.8 lbs make it incredibly difficult to manually lift and transport. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the Champion 100558

The 100558's control panel

The control panel of the 100558 includes an Intelligauge meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

From a security standpoint, the product offers a Volt Guard™ overload protection and 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 100558 also comes with several accessories, including: key fob and funnel.

Emissions

The Champion 100558 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

However, it features a spark arrestor, so it is adequate for use in forested areas.

Product Video

The Champion 100558 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100558 compare to generators of similar power (between 3000 and 4000 W).

  • At a weight of 118.8 pounds, the Champion 100558 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 generator emits noise as low as 68 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.
  • As the 100558 offers around 12 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000X, with around 16 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.39 GPH. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Champion 100558 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
