Zoom on the Champion 200977
In summary, the Champion 200977 is a compact portable inverter generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- People occasionally participating in outdoor fairs, festivals or events
- Amateur DIY lovers
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Tailgating and campground aficionados with the desire of enjoying power anywhere they go
The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, and the extra features it benefits from.
Power & Run Time
The dual-fuel technology of the Champion 200977 allows for an output of 120V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,500W and a starting wattage of 4,250W. If propane-powered, it gives 3,150 rated watts and 4,250 starting watts. Additionally, the parallel capability (ParaLink (opens in a new tab) not included) facilitates increasing of power output when linked to another similar or compatible unit, offering enhanced energy capacity and reliability for diverse requirements.
Rated for 64 dBA (just slightly more noisy than an office), the inverter generator's starting mechanism relies on a traditional recoil pull-start mechanism.
In terms of run time, the 200977, boasting a 4 gallons fuel tank, can run for up to 22 hours on a full tank of gasoline (with fuel consumption averaging 0.18 gallons per hour). Additionally, it provides up to 21 hours (on a 20 lbs tank - propane consumption around 0.22 GPH) of operation with propane.
The 200977 generates a clean sine wave: providing <3% Total Harmonic Distortion (THD), delicate electronics can be plugged in its AC outlets safely.
Outlets
The control panel provides the upcoming 3 AC outlets:
It also sports 2 DC outlets: there's two 5V USB ports (USB-A) designed for hassle-free charging of various electronic devices such as smartphones and tablets, ensuring uninterrupted usage.
Thanks to its TT-30R receptacle (TT stands for 'Travel Trailer'), this Champion generator is RV Ready.
Portability
At L20.9 x W18.3 x H19.4 in, the traditional open frame structure of the Champion 200977 ensures stability while facilitating convenient maintenance access to components and promoting air cooling. This type of design is ideal for tough environments and heavy outdoor use.
Weighing 79 lbs, the 200977 is easily handled, ensuring it can go 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 and its control panel include an Intelligauge meter, offering voltage, frequency, and lifetime hours readings. This feature comes handy when monitoring its status and activity.
In addition to this info, the device's light indicators will illuminate to indicate if the oil level is too low, the generator is overloaded 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.
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.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Champion 200977 also is packed along with the following accessories: 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).
- Regarding its weight, the Champion 200977 only weighs in at 79 pounds, which means it's one of the lighter inverter 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 Pulsar PGD40iSCO, with a dry weight of just 46 pounds.
- In comparison to generators with a similar running wattage, this inverter generator's lowest emitted noise of 64 dBA can be considered noisy. If you value reduced noise levels, the Westinghouse iGen4000DFc could be worth considering. It's one of the quietest generators in its power range, rated at 52 dBA.
- Compared to inverters of similar power, the 200977 stands out with one of the higher run times, lasting up to 22 hours at 25% load. If run time is one of your main concerns, the Firman WH03662OF could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting up to 25 hours.
- Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This inverter generator reaches an estimated fuel consumption of 0.18 GPH (gallon per hour) at a 25% load, making it average, for the previously mentioned wattage range. 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 cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
