Zoom on the Champion 100520

In a nutshell, the Champion 100520 is a powerful portable inverter generator mostly geared towards:

  • Food van owners who know that just a short power outage could lose them hundreds of dollars
  • Camping and tailgating buffs looking to enhance their experience
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 100520 in use

The Champion 100520

The Champion 100520's core is the 420 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 7000W and a peak wattage of 8750W.

Enjoying a noise rating of 72 dBA (just slightly more noisy than a vacuum cleaner), this inverter generator can be started thanks to a conventional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).

The fuel capacity of 4.2 gallons allows the 100520 to operate for up to 10.5 hours with a full tank (fuel consumption around 0.4 GPH).

The 100520 produces a clean sine wave: thanks to a <3% Total Harmonic Disruption (THD), your sensitive electronics can be safely plugged in the AC outlets.

Outlets

The control panel features the upcoming 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Furthermore, it has 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle with which you may charge your batteries with ease.

Because the 100520 is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The design of the Champion 100520 is a typical, open frame, with the dimensions of L26.6 x W25.6 x H23.7 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.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 149 lbs make it incredibly difficult to manually lift and transport. However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the Champion 100520

The 100520's control panel

The 100520 and its control panel include an Intelligauge meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, when its oil levels are insufficient, the generator is overloaded and the generator is ready, you will be informed by the featured light indicators.

The inverter generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 100520, the following accessories are also included: battery charging cables, dual port USB adapter and funnel.

Emissions

The Champion 100520 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 and thus, may be used in forested areas.

The Champion 100520 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 100520 compare to generators of similar power (between 6500 and 7500 W).

  • Regarding its weight, the Champion 100520 only weighs in at 149 pounds, which means it's one of the lighter generators in the 6500-7500 rated wattage range. If weight matters to you, one of the champions in this power range is the Sportsman GEN85KIDF with only 133 pounds.
  • Since the inverter generator's noise is rated at 72 dBA, it has the roughly average expected noise for a device of similar power. For those who are looking for a less noisy device, we suggest the Powerhorse 7500i. With just 55 dBA, it is one of the most quiet devices in this power range.
  • Autonomy-wise, with up to 10.5 hours on a full tank at a 25% load, the 100520 is on the low end when compared to other generators of a similar power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen7500DF, as it provides up to 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This inverter generator can be considered as fuel efficient, due to its low estimated fuel consumption of only 0.4 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV8000, with a fuel consumption of 0.35 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 6500-7500W generators, the Champion 100520 is on the average side of the price range.

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

I read in a review that these types of generators do not have enough compression to adequately operate on Natural Gas. They will do ok with LP but NG requires higher compression for proper operation. Is this correct? (Asked March 01, 2021)

Possible, since this unit is designed to run on gasoline only.

Does the Champion 100520 have the option to add Duel Fuel LP, I saw one supplier say they could add Duel Fuel option for an additional $299 at checkout. Is this a Champion factory addition or sometime the seller was adding. I have not seen anything other than the one supplier offer that for this model 100520. (Asked March 14, 2021)

The unit does not have an official dual fuel option. Beware of third party fuel line modifications, since they could void your warranty and put you in violation of your local emission laws.

    Really quiet for a generator of this size with an open frame construction. There are very few generators that provide clean power and are rated at 7000 running watts that are quieter than this generator, and even then, its not by much. Starts my well pump which is 450 feet deep (I *think* it is 3HP?), without any dimming of the lights. Feels much stronger/more capable than the B&S EXL8000 it is replacing. Very fuel efficient, especially on eco mode. Clean power is amazing, there is no hum from the appliances or electronics. I am not sure why they even make generators that don’t have clean power? Unpacking and set up was quick and easy. I love that virtually all the controls are right in front of you on the main panel. Connected to my existing Connecticut Electric 10 circuit / 7500 watt transfer switch via the L14-30 twist lock and an 8 gauge extension cord, and it ran great. No issues with GFCI tripping as others had reported. I didn’t have to disconnect the neutral bonded to the frame. So far very happy with this unit but still have less than 10 hours on it. All the performance of the Honda EU7000is, and at 1/4 of the cost. The only trade off is the noise level, which isn’t bad.

    + PROS:
    • Clean power, quiet, fuel efficient, seems stronger than rated
    - CONS:
    • Gas tank is a little small.
