Power & Run Time

The Champion 200977 in use

The Champion 200977

Thanks to its dual-fuel technology, the Champion 200977 provides a 120V output and offers both versatility and power. When utilizing gasoline, it delivers a running wattage of 3,500W and a starting wattage of 4,250W. Alternatively, when operating on propane, it provides 3,150 running watts and 4,250 starting 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.

Rated for 64 dBA (just slightly more noisy than background music), the inverter generator's starting mechanism relies on a simple traditional pull-start mechanism.

As for its running time, the 200977, along with its 4 gallons fuel capacity, can run for up to 22 hours with a full tank filled with gasoline (fuel consumption around 0.18 GPH). If propane is used, it can operate for up to 21 hours (on a 20 lbs tank - propane consumption around 0.22 GPH).

With a <3% Total Harmonic Distortion (THD), the 200977 delivers a clean sine wave—essential for safeguarding your delicate electronics when plugged into its AC outlets.

Outlets

The control panel features the upcoming 3 AC outlets:

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

Additionally, it features 2 DC outlets: there's two 5V USB ports (USB-A) ensuring convenient charging of devices like mobile phones and tablets, for connectivity on the go.

The inclusion of a TT-30R receptacle (TT for 'Travel Trailer') makes this Champion generator RV Ready, ideal for providing power to recreational vehicles.

Portability

With a size of L20.9 x W18.3 x H19.4 in, the Champion 200977 features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. The featured design is ideal for the outdoors and all tough environments.

The 200977's dry weight of 79 lbs lets you use its power anywhere needed. Moreover, grabbing and moving this product is made even easier by its open frame design.

Features

Panel of the Champion 200977

The 200977's control panel

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

In addition to this info, light indicators on the device will notify you if the generator is on overload, the generator is ready and the oil level is too low.

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

From a security standpoint, the product offers an automatic low oil shut-off and an overload protection (circuit breaker), allowing you to 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: propane hose, oil and funnel.

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).

  • 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 inverter generators. If weight matters to you, one of the champions in this power range is the Pulsar PGD40iSCO with only 46 pounds.
  • When compared to devices able to produce a similar running wattage, this inverter generator and its lowest emitted noise of 64 dBA is on the noisier side. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500DF. With just 52 dBA, it is one of the most quiet devices in this power range.
  • Since the 200977 boasts with a run time of up to 22 hours at 25% load, it can be safely judged as a device of a higher run time than most inverter generators of a comparable output. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Firman W03661OF, reaching 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. When operating at 25% load, the inverter generator's fuel consumption is estimated at 0.18 GPH, placing it within the average range of gasoline usage among similarly powerful devices. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.13 GPH, the Energizer eZV3500P is a device you could look out for.

Price comparison

As you can see from these interactive charts, when compared to other 3000-4000W dual fuel inverter 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.
