Power & Run Time

The Champion 100403 in use

The Champion 100403

The Champion 100403 is powered by a 80 cc Champion OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 1200W as well as a peak wattage of 1500W.

The generator is rated for a noise of 65 dBA (just slightly more noisy than a normal conversation). Its starting mechanism is based on a conventional pull-start mechanism.

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

Outlets

The control panel provides the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

Portability

The Champion 100403 has a conventional, open frame design, of the following dimensions: L19.3 x W14 x H16 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.

The 100403 can be taken anywhere with you, thanks to its weight of 56.7 lbs. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

The 100403's control panel

The 100403's status and activity may be monitored conveniently via the control panel, as it features an Intelligauge meter showing you voltage, frequency and lifetime hours.

As for its security measures, the device features an automatic low oil shut-off, letting you use it with a peace of mind.

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. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, making it usable 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 500 and 1500 W).

  • Considering its dry weight of 56.7 pounds, the Champion 100403 is one of the heavier generators producing between 500 and 1500 running watts. In terms of weight, one of the champions in their power range is the Sportsman GEN1000i, standing at just 20.3 lbs.
  • Because this generator emits noise as low as 65 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU1000i, whose lowest noise levels reach just 42 dBA.
  • The 100403 provides a higher run time than similarly powerful devices, reaching around 11 hours at 50% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Pulsar PG2000, as it provides around 12 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 has an average fuel consumption among comparably powerful devices, as it reaches 0.15 GPH (gallon per hour) at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.08 GPH, the Ryobi RYi1000 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 500-1500W generators, the Champion 100403 is on the average side of the price range.

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

The bottom line

STRENGTHS:
  • In the expected price range
  • High run time
AVERAGE SPECS:
  • Acceptable noise (65 dBA)
  • Decent fuel efficiency
WEAKNESSES:
  • No electric start
  • On the heavy side (56.7 lbs)
