Description

Zoom on the Champion 100558

In summary, the Champion 100558 is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials

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 is powered by a 208 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4375W.

The generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 68 dBA (less noisy than background music). For additional convenience, the 100558 may also be remotely started (key fob included).

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

The quite high THD (<20%) of the 100558 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes the following 4 AC outlets:

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

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

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 generator is designed for ideal use outdoors and in rough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 118.8 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀8") and its folding handle, once it is placed on the ground.

Features

The 100558's control panel

The 100558 and its control panel include an Intelligauge meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to use it with a peace of mind. Champion's built-in surge protector (Volt Guard™) safeguards your equipment and appliances against voltage spikes.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 100558, the following accessories are also included: 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, which makes it suitable for use in forested areas.

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. 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 generator has a somewhat average expected noise for its power range, rated at 68 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.
  • 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 Predator 4375, with around 16 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.39 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 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 100558 is on the average side of the price range.

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