Zoom on the Champion 100403

In summary, the Champion 100403 is a compact and lightweight portable generator especially useful for:

  • Tailgating and campground aficionados with the desire of enjoying power anywhere they go
  • Amateur DIY lovers

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 100403 in use

The Champion 100403

The Champion 100403 houses a 80 cc Champion OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 1200W along with a peak wattage of 1500W.

With a noise rating of 65 dBA (just slightly more noisy than an office), the generator features a simple traditional pull-start mechanism.

The 100403 can operate for around 11 hours at 50% load with a full tank (fuel consumption around 0.15 GPH), due to its fuel capacity of 1.7 gallon.

As the 100403 has a relatively high THD (<20%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel provides the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

Portability

The Champion 100403 has the following dimensions: L19.3 x W14 x H16 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

With a dry weight of 56.7 lbs, the 100403 can easily follow you wherever your power needs are. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

The 100403's control panel

To help you monitor the 100403's status and activity, its control panel is equipped with an Intelligauge meter showing you voltage, frequency and lifetime hours.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Champion also included a funnel in the 100403's packaging. An official storage cover is also available, as a separate purchase.

Emissions

The Champion 100403 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and thus, may be used in forested areas.

The Champion 100403 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100403 compare to generators of similar power (between 1000 and 2000 W).

  • With a dry weight of 56.7 pounds, the Champion 100403 finds itself in the expected weight range for generators able to produce between 1000 and 2000 rated watts. Regarding dry weight, one of the champions in the same power range is the ECHO EGi-1200, with a dry weight of only 30 lbs.
  • This generator, with its lowest possible noise rated at 65 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If you are concerned with noise, check out the Honda EU2200i, which is one of the least noisy generators in its power range, with a noise rating of just 48 dBA.
  • Since the 100403 boasts with a run time of around 11 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse WGen2000, which is able to run for around 20 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 generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.15 GPH (gallon per hour) at 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Cat INV1250, with a fuel consumption of 0.1 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 1000-2000W generators, the Champion 100403 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.

The bottom line

STRENGTHS:
  • Inexpensive
  • High run time
  • Fuel efficient
AVERAGE SPECS:
  • Decent weight (56.7 lbs)
WEAKNESSES:
  • No electric start
  • On the noisy side (65 dBA)
