Champion 4000 Generator Review

Champion 4000 Watt Generator occupies a very high rank among portable generators, offers many enormous advantages. What distinguishes it from the competition is the remote start: a super convenient feature that allows you to remotely start and stop the generator.

Few generators have this functionality, and Champion 4000 is one of the best out there available. This is a good choice for use on construction sites, camping sites, and Rvs. It’s also reliable and durable enough to serve as an emergency power supply for home and business owners.

Champion 4000 Inverter Generator Review

One of the most innovative products on the market is the Champion Power Equipment 100302 4000-Watt Digital Hybrid Open Frame Inverter Generator. The technological advanced and innovative design will improve the way you power your life.

Champion’s digital hybrid is 50% quieter and 20% lighter than a conventional 3500-watt portable generator. The noise level in halved by integrating Quiet Technology Digital Inverter components. Then, there’s an efficient mechanical design to reduce the overall footprint and weight by 20%.

At the three points of sale of the champion, you can operate all possible of devices. Lamps, televisions, air conditioners, sump pumps, power tools, and more. This generator is pretty fuel-efficient. It delivers an output of up to 4,000 Watts and is very easy to start up.

The frame, handle, and wheels also make it quite easy for such a large generator to be move and manoeuvre.

With 4000 starting watts and 3500 operating watts, this portable generator will meet most of your needs, whether you use it at home during a power outage, at work or during leisure time.

Lightweight and easy to move, this Champion 4000-watt generator gives you total freedom. It is CARB and EPA compliant, so you can even use it in national parks and forests.

The generator dimensions are 28.5 x 21.1 x 20.7 inches and weigh 140 pounds. It may seem heavy, but its handles and wheels make it easy to move. With 4000 starting watts, you can use the generator in a variety of ways.

The quick-touch panel provides quick access to controls, while economy mode monitors power consumption in real-time to reduce the electrical load. When the electrical load is reduced, the engine idles speed is reduced, resulting in quieter operation, longer engine life, and higher fuel economy.

The optional Parallel Kit, with a standard 50 amp RV output jack, provides a clip-on connection that allows you to increase performance by connecting up to two inverter or digital hybrids with a capacity of 2800-watt or more.

If you want to use it during a power outage at home, you can use it to supply your drip pan, fridge, freezer, TV and lights with some electricity. When used on a construction site, you can easily use it to supply power to several power tools with ease.

So what makes this generator a “Digital Hybrid”?

The answer lies in its intelligent design. Champion took the normally closed inverter generator and hung it on an open frame like a normal generator. The idea behind this is to use a larger engine and increase the performance while keeping the cost down.

However, they had to forego part of the noise reduction gains of a completely encapsulated inverter generator. But that doesn’t mean that it sounds like a broken jackhammer. It doesn’t sound any louder than normal human babble.

A mix of performance and clean inverter power output is its strongest point. You get clean, low-distortion, harmonious power that will safely power your most sensitive devices. Portable energy is needed in an emergency.

The complex electronics of the converter technology also controls the speed of the engine according to the power requirement. In contrast to a normal generator, which runs at gentle engine speed, the engine of the inverter generator slows when there’s little demand and increases speed as the load increases. This property saves a lot of fuel and reduces engine wear. You’ll spend less on fuel and maintenance.

The peak output power is at 4000 watts, while the constant and reliable power is 3500 watts. The engine is a Champion 196cc OHV surrounded by a cast iron sleeve.

The Champion’s Digital Hybrid design makes it 50% quieter and 20% lighter than a conventional 3500-watt portable generator. The model’s noise level has been halved by adding parts of the Quiet Technology digital inverter.

A 20 per cent reduction in the overall footprint and weight was achieved by Champion using an efficient mechanical design.  The result is a quiet, lightweight, and powerful inverter generator. A workhorse can assert itself during an emergency or camping trip.

Delivered fully assembled with a durable open steel frame. Powered by a reliable 224 cc. The dimensions (length/width/height), are 29/21/21 inches each. The total weight is 140 lbs. This includes the metal frame and two 8″ wheels that make the generator portable.

The generator is supplied with a wireless starting remote control that works up to 80 feet away. The remote control is powered by a battery that is included in the kit.

There’re three different types of sockets on this generator: a 120V duplex socket, a 120V twist-lock socket, and an RV socket.

The device is equipped with overload protection, a sensor for low oil, and an Intelli-gauge device that gives you information about voltage, hertz, and operating hours at a glance.

The generator can run for 17 hours. And with a full tank of gasoline (capacity of 2.9 gallons) and at 25% load. Making this a perfect hybrid unit for emergencies where fuel may not be immediately available.

You can comfortably run it all night without the stress going out to refuel. The quality of the Champion 100302’s output power comes closes to the quality of the power grid in your household.

With the help of inverter technology, the device generates electricity with pure sine waves and harmonic distortion of less than 3%. Champion 10032 can also run a 15,000 BTU RV air conditioning unit.

Fuel efficient with its intelligent economy mode varies the speed of the engine depending on the load required. When the electric load is reduced, the engine automatically goes into neutral, allowing economical fuel consumption, quiet operation, and long engine life.

With a generous output of 3,500 running watts, the Champion 100302 is very quiet for a generator of its size and power. The noise level is 64 dBA from 23 feet, (only slightly higher than the sound of human conversation).

There are quieter portable inverter generators available with similar ratings. However, only a few can achieve this level of silence, and they are usually much more expensive than the Champion 100302 By hooking the Champion 100302 up to a similar unit, you can increase your power output to 7000-watt.

This requires an optional Parallel Kit (sold separately). With the combined power output, you should be able to conveniently power a large house during an emergency. Starting this machine is easy with a recoil start. Equipped with an automatic shut-off sensor for low oil level and an automatic voltage regulator.

Features a fast touch panel, through which all controls are easily accessible in a comfortable area.

The scope of delivery includes two 120V,20A sockets for domestic use, one 120V,30A socket with RV lock, and 12V automotive DC sockets with a USB adapter and battery charging cables. All are overload-proof.
