Description
Zoom on the Champion 201255
In summary, the Champion 201255 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
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
Running on gasoline, the Champion 201255 operates with a 224 cc OHV 4-stroke engine, delivering 120V, with a running wattage of 4,000W and a peak wattage of 5,500W. In addition, the device is parallel capable (ParaLINK (opens in a new tab) not included) and thus, can be linked to a similar or compatible unit for added power.
Operating at a noise rating of 70 dBA (just as noisy as a vacuum cleaner), this inverter generator starts up with a simple traditional pull-start mechanism. Champion’s EZ Start Dial lets you intuitively start the engine with easy access to all the controls you need.
Thanks to its 2.9 gallons fuel tank, the 201255 can run continuously for up to 16 hours on a full tank (with an average fuel consumption of approximately 0.18 GPH).
As the 201255 produces a clean sine wave, with a <3% Total Harmonic Distortion (THD), sensitive electronics may be plugged in the AC outlets safely.
Outlets
The control panel provides the upcoming 3 AC outlets:
Moreover, it boasts 1 DC outlet: there's a 12V 8A (cigarette lighter style) receptacle providing easy battery charging capabilities.
Equipped with a TT-30R receptacle (TT representing 'Travel Trailer'), this Champion generator is RV Ready, ensuring compatibility with recreational vehicles.
Portability
With dimensions of L21.3 x W17.9 x H17.9 in, the standard open frame design of the Champion 201255 provides stability and easy maintenance access to components, as well as good air circulation. This type of design is ideal for tough environments and heavy outdoor use.
As the 201255's weight is only 81.6 lbs, it can follow you and your power needs anywhere. Furthermore, the open frame of the generator aids in holding and moving it to a different location.
Features
A digital Intelligauge data center, one of the features of the 201255's control panel, gives you information on the voltage, frequency, lifetime run hours and power output, and thus, is helpful for the monitoring of its activity and status.
In addition to this info, a light indicator on the device will notify you if its oil levels are insufficient.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the inverter generator.
Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.
The unit also benefits from the CO Shield™ technology, which monitors accumulation of poisonous carbon monoxide (CO) gas produced by the engine's exhaust when the generator is running. If CO Shield™ detects elevated levels of CO gas, it automatically shuts off the engine and illuminates a red LED.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Champion 201255, the following accessories are also included: funnel, oil and tool kit.
The Champion 201255 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Champion 201255 compare to inverter generators of similar power (between 3500 and 4500 W).
- When it comes to weight, the Champion 201255 tips the scales at just 81.6 pounds, making it one of the lighter inverter generators in the 3500 to 4500 rated wattage range. If weight is an important consideration for you, the WEN 56432iX stands out as one of the top contenders in this power category, with a dry weight of 52.9 pounds.
- If compared to generators capable of producing a similar running wattage, this inverter generator with a lowest emitted noise of 70 dBA can be considered somewhat noisy. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen5000DF with only 52 dBA.
- The 201255 provides up to 16 hours of runtime at a 25% load on a full tank, placing it within the average autonomy range among similar inverter generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Firman WH03662OF, as it provides up to 25 hours.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. With a fuel consumption rate around 0.18 GPH (gallon per hour) at 25% load, this inverter generator is one of the more fuel-efficient models within the aforementioned wattage range. If you wish to further improve in the area of fuel efficiency, the Champion 201319, which boasts with a gas consumption of only 0.16 GPH, may be the right generator for you.
Price comparison
As you can see from these interactive charts, when compared to other 3500-4500W inverter generators, the Champion 201255 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
