Power & Run Time

The Champion 100403 in use

The Champion 100403

The Champion 100403's engine, 80 cc Champion OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 1200W and reaches a peak wattage of 1500W.

The generator features a conventional pull-start mechanism. It is rated for a noise of 65 dBA (just slightly more noisy than background music).

With a fuel capacity of 1.7 gallon, the 100403 may run for around 11 hours at 50% load with a full tank (fuel consumption around 0.15 GPH).

Outlets

The control panel features the upcoming 2 AC outlets:

Duplex 120V 20A (5-20R)

Portability

With its dimensions of L19.3 x W14 x H16 in, the conventional, open frame design of the Champion 100403 offers stability and allows the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

The 100403 can be taken anywhere with you, thanks to its weight of 56.7 lbs. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

The 100403's control panel

The control panel of the 100403 includes an Intelligauge meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

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.

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 500 and 1500 W).

  • At a dry weight of 56.7 pounds, the Champion 100403 is one of the heavier devices which can produce between 500 and 1500 running watts. If weight matters to you, one of the champions in this power range is the Sportsman GEN1000i with only 20.3 pounds.
  • 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 noise emissions are important to you, one of the least noisy generators of this power range is the Honda EU1000i with only 42 dBA.
  • Thanks to an impressive running time of around 11 hours at 50% load, the 100403 benefits from a higher run time than many generators of a similar output. 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.
  • 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. As this generator uses an estimated 0.15 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Ryobi RYi1000, with a fuel consumption of 0.08 GPH could be in your good books.

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
