The Champion Power Equipment brand was established in 2003 and has, in a short period of time, become a central player in the generator manufacturing industry.
It has joined other brands such as Briggs and Stratton, Yamaha, and Honda in the league of high-quality manufacturers.
The Champion 75537i, 3100W model is one of such high-end inverter generator they make. Since it is an inverter generator, it pulls out all the stops in terms of technology.
It has the option of a wireless remote start, its engine adjusts the RPM rate according to the load, and it can give both AC and DC outputs.
This model, as can be seen from just some preliminary features, utilizes the advanced technology which goes into making inverter generators to a high degree.
Apart from technology, it also has convenient manual features such as integrated wheels to enhance the convenience and ease of using it.
Design, Dimensions & Weight
The design of the Champion 75537i, the 3100W inverter generator is a highly compact, well-organized blend of technological features and more traditional manual ones.
With a length of 25.1 inches, the width of 17.3 inches, and a height of 18.3 inches, it is clear that it packs a number of functions into its small volume.
It has a weight of 96.6 lbs with an empty tank, which increases to around 107 lbs with a tank fuel filled with gasoline to its 1.6 gallon/6 liter capacity.
This is not too heavy a weight and for users who might have issues with this, it comes with integrated wheels and handles which make it easy to move around and maneuver.
In terms of weight, this model is on the lower half of the range of weights out of the models we have reviewed and analysed.
It is a few pounds under the 100 lbs mark.
However, there are definitely lighter models, and the Champion 75531i has a comparable fuel tank capacity with a considerably lower weight.
The following table provides further details on comparative weights:
Table: This model is on the lower half of the weight spectrum
Its display is sleek and the controls are concentrated on one neatly labelled and highly efficient panel with prominent warning and safety signs on the top to familiarize new users with proper precautions.
If you wish to get a better spatial idea of the size of this model, Champion Power Equipment has uploaded a video showcasing this generator in a variety of situations.
You can use this video to assess the convenience and suitability of this model for yourself at :
Power Output / Generation
This inverter generator is capable of producing a continuous running AC supply of 2800W and a surge power of 3100W at 120V.
This means that it is engineered specifically for its RV audience and can be used to power a number of electrical items required by such users.
This is not a very high running output and it is the second lowest running wattage of the reviewed generators, tied with a few other models.
There are a number of models with a higher output which can be viewed here:
Table: This model has a low running power
It can power more intensive items such as microwaves, ACs, and fridges along with smaller electronic items such as modems or laptops. It is also capable of powering one or two small power tools.
Its 171cc Champion 4-Stroke OHV engine is manufactured by Champion itself and is capable of producing 8 hours of continuous electricity supply with a full tank of gasoline at a 25% load.
Since it an inverter generator, this engine can also reduce its RPM according to the load thus increasing its efficiency.
Apart from making it more efficient, this also makes it capable of producing a more steady supply of power along with producing fewer environmentally harmful emissions.
You should remember that since this is a 4-stroke engine, only an engine oil appropriate for a 4-stroke engine can be used.
Champion, in particular, recommends a SAE 10W-30 oil. Oil specifications should not unduly worry you as most oil bottles prominently display their specification on the front label of the product under the brand name.
Fuel and Noise
The Champion 75537i is a CARB compliant generator. This means that it can be used in all 50 states, including California as it meets the more stringent requirements placed on generators in the state to control smog.
For fuel, the engine requires unleaded gasoline. Specifically, gasoline with an octane rating of above 85.
This should not be hard to find as commercially available gasoline is of a rating of 86 or higher. Furthermore, the rating is displayed prominently on the label which makes it easy to locate the grade you are looking for.
The gasoline should, however, not contain more than 10% ethanol by volume in it.
With the 1.6 gallon/ 6 liter tank filled to capacity with gasoline, this generator should run for 8 hours on a 25% load.
This is quite a low tank capacity as per a comparative analysis. In fact, this is the second lowest fuel tank capacity out of the reviewed models, tied with another Champion generator.
This means that it will run for a shorter period of time than models with power outputs in a similar range.
You can see models with higher fuel capacities here:
Table: This model has a low fuel capacity
Noise can possibly become an issue with this model as it produces a noise level of 58 dB at a distance of 23 feet from it.
If you are not familiar with decibel rating, this noise level is around that of a typical conversation. This makes it tolerable at an appropriate distance.
This noise level is on the lower side out of the models reviewed – it is actually the third lowest decibel rating.
Only two models have a lower noise level than this model and only one is significantly lower in noise, with the other one being lower by just one decibel.
The complete comparison table is available here:
Table: This model has a low noise level
However, if you do not have the space required to keep it so far off, it is possible that the noise from this generator can create disturbances and annoyance.
Display & Control Panel
This display is extremely compact and well-labeled. Warning, safety, and danger labels are situated in a prominent location on the top of the generator.
Thus, even first time users who haven’t read the manual are immediately familiarized with basic safety procedures.
The control panel is compact, highly organized, and well-labeled.
There is a multitude of controls which are efficiently fitted into the panel and are labelled.
However, this labelling is done in a small font which can make it hard to decipher for people with weak eyesight.
The controls on the panel are as follows:
- Fuel Valve Knob: Used to control fuel supply to the engine
- Choke Push-Button: Used to control the choke valve in the carburetor
- Economy Control Switch: Used to turn the economy mode, which reduces engine operating during lower loads, on and off
- Wireless Set Button: Part of the remote start system
