Power & Run Time

The Champion 200977 in use

The Champion 200977

Thanks to its dual-fuel technology, the Champion 200977 delivers 120V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3500W and a peak wattage of 4250W. When propane-powered, it has 3150 rated watts and 4250 peak watts. Additionally, as the generator is parallel capable (ParaLink (opens in a new tab) not included), it can be linked to a second unit for more power.

The inverter generator is rated for a noise of 64 dBA (just slightly more noisy than an office). Its starting mechanism is based on a simple traditional 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 generates a clean sine wave: providing <3% Total Harmonic Disruption (THD), delicate electronics can be plugged in its AC outlets safely.

Outlets

The control panel provides the upcoming 3 AC outlets:

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

In addition, it provides 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, thanks to its TT-30R receptacle (TT stands for 'Travel Trailer').

Portability

The design of the Champion 200977 is a typical, open frame, with the dimensions of L20.9 x W18.3 x H19.4 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

The 200977's dry weight of 79 lbs lets you use its power anywhere needed. Furthermore, the open frame of the generator further helps when holding and moving it to a different place.

Features

Panel of the Champion 200977

The 200977's control panel

The 200977 and its control panel include an Intelligauge meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.

In addition to this info, the light indicators show you if its oil levels are insufficient, the generator is on overload and the generator is ready.

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.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Champion 200977's package also includes these accessories: propane hose, funnel and oil.

Emissions

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

Product Video

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. 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.
  • Because this inverter generator emits noise as low as 64 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. 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.
  • The 200977 provides one of the highest run time among similarly powerful devices, reaching up to 22 hours at 25% load.
  • 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. This inverter generator, with an estimated fuel consumption of just 0.18 GPH (gallon per hour) at 25% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If you wish to further improve in the area of fuel efficiency, the Energizer eZV3500P, which boasts with a gas consumption of only 0.13 GPH, may be the right generator for you.

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.
