The Champion 46539 is a traditional generator capable of producing a power supply of 3,500W of continuous power and 4,000W of surge power, making it ideal not just for RV or trailer users but also partial household needs.

Capable of running both heavy-duty devices such as ACs, refrigerators and TVs to less power consuming ones such as modems or laptops, it exemplifies the reliable and durable generators that Champion has been known to create.

Started in 2003, Champion Power Equipment is now a major player in the high-quality portable generator market.

Often seen as more economical than competitors such as Honda or Yamaha, its generators consistently receive high reviews from customers.

They are known to be sturdy, durable, and good quality and the Champion 46539 is no exception.

Design, Dimensions & Weight

Champion 46539

Since the Champion 46539 is not an inverter generator, and as such its component parts are not contained within a central unit. Rather, parts such as the engine and the fuel valve are clearly visible and are located within a steel frame.

This steel frame provides this model with strength and longevity by enhancing its hardiness.

However, the use of steel instead of hard plastic also means that the weight of this generator is high, coming in at a dry weight of 124.6 lbs and around 148 lbs with its 3.8 gallon/14.4 liter fuel tank filled to capacity with gasoline.

This weight is definitely on the higher side, which can make it cumbersome to transport or store easily. If you wish to look at generators with a lower weight, you can look at the following table:

However, it comes with a set of two wheels attached to it which can enhance its mobility for being dragged around.

In terms of dimensions, it is over two feet in length at 26.3 inches, about two feet in width at 24.4 inches, and a height of 22.4 inches. As such, it is quite sizeable in terms of size.

For a better idea of how this generator compares in terms of size and fit in various situations where it can be used you can watch the official Champion Power Equipment video of the model at:

Power Output / Generation

The 3500W running power and 4000W surge power of this generator are provided by the 196cc Champion 4-Stroke OHV engine manufactured by Champion Power Equipment itself.

This makes it ideal not just for RV or trailer users but also for those who wish to use the Champion 46539 for partial household purposes as well.

This is a high level of running wattage, which is characteristic of a number of Champion’s generators which provide the same level of power.

There are only a couple of models with a higher running wattage than this one in the 3000W-4000W range. These can be viewed in this table:Champion 46539 Running power

It can power all sorts of electrical items, from 15000 BTU ACs to modems, and from fridges to laptops, along with a couple of power tools.

With its large fuel tank of 3.8 gallons/14.4 liters, when filled with gasoline it is capable of providing a whopping 12 hours of steady and continuous supply at 50% load.

This can make it ideal for those who wish to use it for their houses during extended power cuts or blackouts.

As can be seen from the following comparison table, this fuel tank capacity is one of the highest ones available, making it a good choice for those who want a long usage period:

Champion 46539 Fuel Capacity


This engine, being a four-stroke engine, should be serviced properly with oil meant for such an engine type, with Champion prescribing a SAE 10W-30 oil.

Oil specifications should not unduly worry you as most oil containers display their specification on the front label of the product under the brand name.

Fuel and Noise

As an EPA and CARB compliant generator, it meets the regulations placed on portable generators in California and can thus be used in all 50 states.

The engine on Champion 46539, as mentioned before, uses gasoline as fuel to fill its 3.8 gallon/ 14.4 liter fuel tank.

This gasoline must be unleaded and contain less than 10% by volume of ethanol. Furthermore, it must have an octane rating of above 85.

Octane ratings shouldn’t particularly worry users since almost all commercially available gasoline has a rating of 86 or higher.

Furthermore, the rating is usually written on the front label of the gasoline container, making it easy to find the grade you are looking for.

Noise on this generator can be a definite problem while using it – it has a noise level of 68 dB at a distance of 23 ft from the generator.

To get a better sense of this, this is around the noise level of a freeway when you are standing near to it.

This can make the generator loud and annoying if you do not have the space to keep the generator a considerable distance away from you.

This can also end up ruining the ambiance on a camping trip if you use your generator in such a situation.

In terms of comparative analysis, this model has one of the highest decibel levels of the models we have reviewed.

This seems to be a common fault with Champion’s generators. If you wish to look at generators with a lower noise level, you can look at the following table:

However, run time on this generator is extremely good and it is capable of running up to 12 hours on a 50% load with its tank filled completely.

Display & Control Panel

Champion 46539 control panel

The display of the Champion 46593 is well thought-out and designed. The warning labels take into account that since the component parts are clearly visible in this model and as such they are positioned near the appropriate components.

The controls, however, are spread over across the generator rather than being concentrated on the control panel which can make it laborious and time-consuming to use until you have familiarized yourself with it thoroughly.

Conversely, this also means that the control panel is without clutter and is neatly arranged and still retains some central controls.

While switches are labelled in small fonts, which can make them hard to read, the receptacles are very clearly marked thus reducing the risk of accidentally plugging in the wrong load into the generator.

While controls such as the fuel valve or choke lever are located near their respective parts, the following controls can be found on the panel:

Intelligauge: A special digital gauge fitted to this model which tracks the hours it has been used for, the current voltage output, and the frequency of the current

Ignition Switch

Circuit Breakers: There are two of these which prevent the generator from being overloaded

Battery Switch: used for electric and remote starting

Ground Terminal: used for grounding of the generator – familiarize yourself with local regulations before grounding it

3 Receptacles: 120 Volt AC, 30 Amp Twist-Lock receptacle, a regular 120V, 30 Amp receptacle, and a 120V, 20 Amp receptacle

Startup and Shut down

Apart from the usual electric and manual starts which can be found in many generators, this model also has a remote start which can be used within 80 feet of the generator.

Remote Start

The wireless remote start system is a convenient procedure which can be especially useful when the generator has to be turned on and off multiple times.

To use this feature, the generator’s fuel valve, battery, and ignitions switches must be on the ON position.

Then, it is simply a matter of pressing the START button on the remote.

While it is advisable to not have loads connected to the generator at this point, the generator has its own safety feature which ensures that power supply starts only after 15 seconds after remote start.

The remote start auto-chokes and it attempts the starting procedure a total of 6 times. If it does not start in these 6 attempts then it stops.

In such a scenario, you are advised to check whether the appropriate switches are on and whether the battery is working properly.

Electric Start

Before performing the electric start, ensure that the generator is on a smooth flat surface with plenty of open space and has all electrical loads disconnected from it. After this, follow these steps:

  • Rotate the fuel valve to ON position
  • Turn the battery switch ON
  • Push the Choke button to the CHOKE position
  • Flip the engine switch ON
  • Press and hold the ignition switch to START position and wait until the engine begins to run and starts to warm up

Remote Start

Remote start procedure is very similar to the electric start. Before starting, once again you must ensure that there are no loads connected to the generator and that the generator is placed in a open space on a flat surface.

Then, perform the following steps:

  • Rotate the fuel valve to ON position
  • Turn the battery switch ON
  • Push the Choke button to the CHOKE position
  • Flip the engine switch ON
  • Pull the starter cord slowly until you feel resistance and then pull it sharply and quickly
  • As the engine begins to warm up, press the Choke button down to the RUN position

Stopping Procedure

To stop the generator, first, disconnect all the loads from it and let it run for a few minutes so as to stabilize the internal temperature. Then follow these steps:

  • Turn the fuel valve OFF
  • Let the engine run till fuel starvation (this will take a few minutes) and then flip the engine switch OFF
  • Press the battery switch OFF

Additional Features

The Champion 46539 comes with a number of additional features, which are both manual and technological in nature. They are as follows:

Integrated Wheels

This generator comes with two 8-inch no-flat wheels integrated into it rather than as a separate mobility kit which eliminates the hassle of installing them while increasing mobility – however, this might cause problems in transport since some users prefer removing wheels to decrease the size of a generator

Remote Start

The remote start feature is a highly convenient feature which can allow you to turn the generator on from a distance of up to 80 feet


This is a special digital gauge designed by Champion fitted into this model which allows you to keep track of not only the hours your generator has been used for but also the current voltage and frequency of the AC being produced
