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 3,500W and a peak wattage of 4,250W. When propane-powered, it has 3,150 rated watts and 4,250 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 features a conventional pull-start mechanism. It is rated for a noise of 64 dBA (just slightly more noisy than a normal conversation).

Regarding its running time, the 200977, with a 4 gallons fuel capacity can operate for up to 22 hours with a full tank of gasoline (fuel consumption around 0.18 GPH). When using propane, it can run for up to 21 hours (on a 20 lbs tank - propane consumption around 0.22 GPH).

Delicate electronics can be plugged in an AC outlets safely, as the 200977 generates a clean sine wave, reaching a <3% Total Harmonic Distortion (THD).

Outlets

The control panel features the upcoming 3 AC outlets:

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

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

Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Champion generator is RV Ready.

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 featured design is ideal for the outdoors and all tough environments.

The 200977 can be taken anywhere with you, thanks to its weight of 79 lbs. Moreover, its open frame design makes it incredibly easy to grab the frame in order to change its location.

Features

The 200977's control panel

The 200977's status and activity may be monitored conveniently via the control panel, as it features an Intelligauge meter showing you voltage, frequency and lifetime hours.

In addition to this info, the light indicators show you if the generator is overloaded, the generator is ready and the oil level is too low.

The inverter generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Champion 200977 also comes with several accessories, including: 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, so it is adequate for use 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 inverter generators of similar power (between 3000 and 4000 W).

  • In terms of its dry weight, the Champion 200977 stands at only 79 lbs, meaning that is one of the lighter inverters of the 3000-4000 rated wattage category If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
  • This inverter generator, with its lowest possible noise rated at 64 dBA falls into the more noisy category, compared to other devices of a similar running wattage. 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 Westinghouse iGen4500DF, whose lowest noise levels reach just 52 dBA.
  • As the 200977 features an autonomy of up to 22 hours at 25% load, it has a higher run time than an average generator of its type and power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Firman W03661OF, which is able to run for up to 25 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. Standing at an estimated 0.18 GPH (gallon per hour) at a 25% load, this inverter generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Energizer eZV3500P, with a fuel consumption of 0.13 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W dual fuel inverter generators, the Champion 200977 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.
