Champion 4000-Watt DH Series Inverter Generator Review


Champion 4000-Watt DH Series




Noise Level




The Champion 4000-Watt DH Series Inverter Generator is a reliable, powerful, and quiet generator that comes with a host of features. It runs consistently at 3500 watts, which is more than enough to operate refrigerators, RV air conditioners, and various other appliances. But is this generator worth buying? Or should people look for another model? This review will help in making the right buying decision.

This is one of the few generator models that come with an open frame design. It allows the generator to use a relatively bigger engine than its competitors at a lower cost. However, it doesn’t come with an electric start button. The user has to pull the recoil cord to start the generator.

It has a single knob that lets the user adjust the engine’s choke. This makes it easier to quick-start the generator. All one has to do is pull the cord swiftly to start the engine. There is a control panel on the right of the pull cord. It has an engine on/off switch that the user needs to switch on before pulling the cord. Pressing that button turns the engine’s generator on and off. Users will also notice an eco switch just below the engine on/off switch. It enables the Economic mode to save fuel and increase the generator’s run time.

There are three LED indicator lights on the right of the Eco-switch. They indicate the OK status of three things: low fuel warning, malfunction warning, and overload warning. These lights should remain green. The user needs to refill the fuel tank or contact a generator repair technician if any of the lights turn red.

Overall Design

The Champion generator has an open frame design. This has two significant benefits: first of all, it makes the generator 20% lighter. Users can carry the generator for their fishing, camping, and tailgating trips. Secondly, it is 50% quieter than most of its competitors. A noisy generator can become annoying after some time. People want a generator that can provide sufficient power to their appliances without making noise. This generator fulfills that wish. The only drawback in its design is it doesn’t have caster wheels. It weighs 81.6 lbs, which is still lighter compared to most of its counterparts. But users will need a helping hand to carry the generator around. They can buy a wheel and handle kit separately. In fact, it’s best to buy a wheel and handle kit and a Champion generator cover to protect the generator from getting dirty.


This generator has various outlets that can power almost any appliance that a person may have in his house or RV. Suppose someone wants to use two 120V DC outlets, a 120V RV outlet, and a 12V cigarette lighter together. With its 3500 running watts, this generator can efficiently run all of them without showing signs of concern. In case the user overloads the generator, he can use the three reset buttons to get the generator back up and running again.

The unique feature about its outlets is it allows parallel connections. Most generators don’t support this feature as they don’t have the necessary outlets. This means the user can hook up a parallel kit and attach it to the generator to power more appliances. But users need to buy the parallel kit separately. It doesn’t come in the Champion 4000’s box.

Noise Level

No one wants a generator that makes unbearable noises as soon as it starts. Fortunately, the Champion 4000 isn’t from that category. A noisy generator is not only a nuisance to the user but also the neighbors. The Champion, thanks to its open-frame design, is 50% quieter than most other models. Its quiet technology keeps the noise level to only 64 decibels, which is way lower than most generators. The noise feels as if someone is having a conversation 23 feet away. It’s more like a low purring sound and not a constant rumbling noise that most generators make.

The Champion 4000 has a massive 2.9-gallon fuel tank. It can last up to 17 hours if the user runs it at 25% power. Most importantly, this digital inverter model allows the raw power to convert from DC to AC instantly. This function ensures that people can use the generator to power sensitive electronic appliances. Here are a few more standout features of the capacity and gas consumption that keeps the Champion ahead of its competitors:

• Frequency: 60 Hz
• 120 VAC Rated AC Voltage
• 3500W AC Rated Output Running Watts
• 4000W AC Maximum Output Starting Watts
• Rated Amps: 29.2 Amps @ 120 Volts

It comes with a three-year limited warranty, along with free lifetime technical support. The Champion experts are always ready to help whenever users or enthusiastic buyers have questions about this generator.
