In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The Champion 200977 in use

The Champion 200977

With its dual-fuel technology, the powerful and versatile Champion 200977 provides an output of 120V. While gasoline-powered, it gives a running wattage of 3500W along with a peak wattage of 4250W. While propane-powered, it provides 3150 rated watts and 4250 starting watts. In addition, as it is parallel capable (ParaLink (opens in a new tab) not included), this power can be doubled when linked to another similar or compatible unit.

With a noise rating of 64 dBA (just slightly more noisy than a normal conversation), the inverter generator features a conventional pull-start mechanism.

With a fuel capacity of 4 gallons, the 200977 can operate for up to 22 hours using gasoline (fuel consumption around 0.18 GPH), or for up to 21 hours (on a 20 lbs tank - propane consumption around 0.22 GPH) using propane.

The 200977 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 includes the following 3 AC outlets:

Duplex 120V 20A (5-20R)
120V 30A (TT-30R) receptacle

Furthermore, it has 2 DC outlets: there's two 5V USB ports (USB-A) with which charging of electronics like mobile phones and tablets is made convenient.

This Champion generator is RV Ready, as it features a TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The Champion 200977 has the following dimensions: L20.9 x W18.3 x H19.4 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

The 200977 can be taken anywhere with you, thanks to its weight of 79 lbs. In addition, it is even easier to grab and move the generator around thanks to its open frame design.

Features

The 200977's control panel

To help you monitor the 200977's status and activity, its control panel is equipped with an Intelligauge meter showing you voltage, frequency and lifetime hours.

In addition to this info, several light indicators serve to show you when the generator is ready, the generator is on overload and the oil level is too low.

Thanks to a built-in fuel gauge, the inverter generator allows you to quickly, conveniently and easily check the gas level at a glance.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 200977, the following accessories are also included: funnel, oil and propane hose.

Emissions

The Champion 200977 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 and therefore, can be used in forested areas.

The Champion 200977 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Champion 200977 compare to generators of similar power (between 3000 and 4000 W).

  • As far as its dry weight is concerned, the Champion 200977 weighs just 79 pounds and thus, it is one of the lighter 3000 to 4000 rated wattage generators. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • The inverter generator can be considered average in its noise for its power category, as it is rated at 64 dBA. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
  • As the 200977 features an autonomy of up to 22 hours at 25% load, it has one of the highest run times in comparison to the other generators of its power range.
  • 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 inverter generator is one of the more fuel efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.18 GPH (gallon per hour) at 25% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P 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 200977 is on the average side of the price range.

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