Any generator that produces an average power of 4000W is perfect for outdoor activities like camping, RV etc. But why do we keep Champion on the top table? Yes, it is an inverter generator that comes with impressive features and specifications. To your surprise, Champion generators are available at an affordable price. To know more, keep reading.

Why do we prefer using the Champion 4000W inverter generator?

Champion satisfies your basic expectations from a generator like quiet technology and sufficient outlets. Although the unit doesn't have an attached pair of wheels, the durable frame is easy to hold while porting the generator. You can also make transportation super convenient by purchasing a separate wheel kit.

The noise level of this generator is about 64 decibels. This decibel rating is suitable for outdoor activities since the generator will not be a public nuisance. Importantly, an output wattage of 4000W is enough to keep the essential devices active. In addition, you can also use this generator to run small power tools at job sites. 

Champion 4000W inverter generator- An overview 

As discussed earlier, the Champion 4000W inverter generator is one of the most affordable generators available in today's market. Although the generator is an open frame, the inverter technology equipped with the unit makes it quieter irrespective of any applied loads. In addition, the unit is installed with noise mufflers to cut down the decibel ratings. 

When it comes to size, this generator is compact compared to other equivalents. Generally, the THD (Total Harmonic Distortion) touches around 25% in an open frame generator. Since this generator follows an inverter mechanism, the THD is only about 5%. So, the power is stable and is safe to run sensitive devices like smartphones, tablets and laptops.

Unlike traditional generators, this generator features an eco-mode. This mechanism will control the engine's RPM based on the power demands. So, you can utilize the fuel efficiently and get extended runtime. A 2.9-gallon tank offers an impressive runtime of about 17 hours at an applied 25% load. If the output wattage is not enough, you can make use of parallel compatible options. So, you can connect two similar Champion 4000W generators to double the output power. 

Although the generator size is small, there is no compromise in the engine size. It comes with a powerful 224cc four-stroke OHV engine for delivering versatile performance. In fact, generators tend to raise the noise when higher loads are applied. But this air-cooled OHV engine is an exception. It manages to maintain low decibel ratings at applied higher loads.

This model comes with a manual recoil system. Although there is no electric starter, the ColdRush technology will kick start the engine without any starting troubles during the winter season. 

The exterior frame comes with a convenient, durable design. It is lightweight and doesn't come with attached wheels and handlebars.

A detailed review on Champion 4000W inverter generator

Easy to use and Control Panel

Champion 4000W inverter generator comes with an open frame design. It operates at a low decibel rating compared to other traditional generators. The generator's engine ignites with just one pull. Very importantly, the ColdRush technology equipped with the engine will eliminate any starting troubles during cold weather conditions. 

At the side of the unit, there is a user-friendly control panel. It consists of all important controlling switches like an ON/OFF switch, smart eco-mode, parallel port and power outlets. 

There is a smart eco-mode to utilize the fuel efficiently. You can connect multiple devices simultaneously using power outlets like a 12V cigarette lighter-style outlet, two 120V DC outlets and a 12V DC outlet for battery charging. Plus, you can extend the runtime by connecting limited loads. 

The LED lights indicate the output ready and oil levels. These LED lights will alert the user about the generator's internal workings. Apart from this, there is a parallel port to double the output wattage.


Generally, open frame generators are bulky and louder. In the case of the Champion generator, it is relatively quiet and lightweight than other similar models. So, you can transport the generator with ease. In fact, an open frame generator weighing up to 82 pounds is incredible.

Quiet technology

This generator is equipped with inverter technology. It ensures whether a pure sine wave is produced with the least harmonic distortion. The power is stable without any voltage fluctuations. So, you can run sensitive devices like laptops and tablets without causing any damage.

Power output, runtime and tank capacity 

 A 224cc four-stroke OHV engine provides a peak watt of 4000W and a continuous watt of 3500W. This generated power output is sufficient to run essential devices while camping. You can connect two similar generators to increase the output power up to 8000W. A 2.9-gallon fuel tank offers a runtime of about 17 hours at applied quarter load.
