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.

At a noise rating of 64 dBA (just slightly more noisy than a normal conversation), the inverter generator is started via a simple traditional pull-start mechanism.

The 200977, with a fuel capacity of 4 gallons, reaches a run time of up to 22 hours utilizing gasoline (fuel consumption around 0.18 GPH). Alternatively, it can reach a run time of up to 21 hours (on a 20 lbs tank - propane consumption around 0.22 GPH) with propane.

Sensitive electronics can be safely plugged in the AC outlets, as the 200977 produces a clean sine wave, with a <3% Total Harmonic Disruption (THD).

Outlets

The control panel includes the following 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) with which charging of electronics like mobile phones and tablets is made convenient.

With its TT-30R receptacle (TT as in 'Travel Trailer'), this Champion generator is RV Ready.

Portability

The dimensions of the Champion 200977, which are L20.9 x W18.3 x H19.4 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

With a dry weight of 79 lbs, the 200977 can easily follow you wherever your power needs are. 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, some light indicators allow you to instantly see if the generator is ready, the oil level is too low and the generator is on overload.

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 standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Champion 200977 also comes with some accessories: funnel, propane hose and oil are included.

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, which makes it suitable 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 generators of similar power (between 3000 and 4000 W).

  • Regarding its weight, the Champion 200977 only weighs in at 79 pounds, which means it's one of the lighter generators in the 3000-4000 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • As this inverter generator can emit noise as low as 64 dBA, it finds itself in the average expected noise for this kind of power. If you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • Since the 200977 boasts with a run time of up to 22 hours at 25% load, it can be safely judged as one of the devices with the highest run time among those of a comparable output.
  • 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. As this inverter generator uses an estimated 0.18 GPH (gallon per hour) at a 25% load, it finds itself in the average gasoline consumption range of similar products. 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.
