Zoom on the Champion 100403

In a nutshell, the Champion 100403 is a compact and lightweight portable generator mostly geared towards:

  • Camping and tailgating hobbyists looking for a portable power source
  • Handcrafting enthusiasts who wish to work on-the-go

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

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.

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

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.

The powering of sensitive electronic devices with the 100403 is not recommended due to its relatively high THD (<20%).

Outlets

The control panel includes the following 2 AC outlets:

Duplex 120V 20A (5-20R)

Portability

The dimensions of the Champion 100403, which are L19.3 x W14 x H16 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

The 56.7 lbs of the 100403's dry weight enables you to use it anywhere you will ever need. 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

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.

From a security standpoint, the product offers an automatic low oil shut-off, allowing you to 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. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use 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).

  • Having a dry weight of 56.7 lbs, the Champion 100403 belongs in the expected weight range for generators which produce 1000 to 2000 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the ECHO EGi-1200, with a dry weight of just 30 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 65 dBA can be considered somewhat noisy. 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 EU2200i, whose lowest noise levels reach 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. 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 Westinghouse WGen2000, with around 20 hours.
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. This generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.15 GPH (gallon per hour) at 50% load, within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Cat INV1250, which boasts with a gas consumption of only 0.1 GPH, may be the right generator for you.

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)
