Zoom on the Champion 100307

In summary, the Champion 100307 is a compact 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
  • DIYers who wish to improve their efficiency with tools
  • Homeowners in need of an emergency backup power for their essentials

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 100307 in use

The Champion 100307

The dual-fuel technology of the Champion 100307 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3500W and a starting wattage of 4375W. If propane-powered, it gives 3150 rated watts and 3950 starting watts.

Enjoying a noise rating of 68 dBA (less noisy than an office), this generator gets running thanks to a simple traditional pull-start mechanism.

Regarding its running time, the 100307, with a 3.4 gallons fuel capacity can operate for around 9 hours at 50% load with a full tank of gasoline (fuel consumption around 0.38 GPH). When using propane, it can run for around 10.5 hours (on a 20 lbs tank - propane consumption around 0.45 GPH).

As the 100307 has a relatively high THD (<20%), it is not recommended to use it to power 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

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Champion generator is RV Ready.

Portability

The design of the Champion 100307 is a typical, open frame, with the dimensions of L23.2 x W19.1 x H20 in, offering support and stability and enabling the possibility of raising it above ground level. This type of design is ideal for tough environments and heavy outdoor use.

Since the generator weighs 104.9 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Thus, you may also want to consider purchasing its official wheel kit (opens in a new tab).

Features

Panel of the Champion 100307

The 100307's control panel

The control panel of the 100307 includes an Intelligauge meter showing you voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

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 and an overload protection (circuit breaker). Champion's built-in surge protector (Volt Guard™) safeguards your equipment and appliances against voltage spikes.

Besides the usual set of documentation and owner's manual (opens in a new tab) to get you promptly started, Champion also included a propane hose in the 100307's packaging.

Emissions

The Champion 100307 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, so it is adequate for use in forested areas.

Product Video

The Champion 100307 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100307 compare to generators of similar power (between 3000 and 4000 W).

  • Since the generator weighs in at a dry weight of 104.9 lbs, the Champion 100307 belongs in the expected weight range for devices which can produce between 3000 and 4000 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
  • As this generator can emit noise as low as 68 dBA, it finds itself in the average expected noise for this kind of power. 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 for its autonomy, the 100307, with an autonomy of around 9 hours at a 50% load, is placed on the low end among the generators of its kind. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 4375, which is able to run for around 16 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.38 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the Champion 100307 is on the average side of the price range.

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