Whether you need to power an RV or small tools or you deal with frequent outages, an inverter or portable generator is an invaluable tool. But choosing the right one can be difficult. Let’s take a look at the Champion 100520 8750W Gas Inverter Generator.
Champion Power Equipment Brand Overview
Champion Power Equipment was founded in 2003 in Santa Fe Springs, California. The company expanded over the years into an international brand with manufacturing plants in Jackson, Tennessee; Milwaukee, Wisconsin; and Toronto, Canada. The brand also has an in-house engineering team at its product design and development facilities in Milwaukee.
Champion is a familiar brand regularly found at hardware and home department stores. The company now makes a variety of products from engines, winches, and log splitters to portable and standby generators and inverter generators. Champion generators range from small and easily portable to large power machines. With 2.5 million generators sold, Champion is a household name for recreational and home-use generators.
The Champion 100520 8750W gas inverter generator is an open-frame gas inverter with a push-button electric start. Like all inverters and generators, it’s suitable only for outside use for safety reasons.
Many inverters are a closed-frame system, which cushions some of the engine sound and makes a quieter machine. The open-frame generators are easy to service, but the trade-off is less cushion for sound. At 8,750 watts and a 420-cubic-centimeter engine, this machine can power quite a few appliances, but the open frame makes it slightly louder. Still, it’s quieter than a traditional portable generator of the same size.
Inverter generators and other portable generators use combustion to turn fuel into energy or heat and then into electrical power. They both also use an alternator to make alternating current (AC). The difference is that an inverter takes that AC power and converts it into direct current (DC), sends it through a microprocessor, and converts it back to AC power. The result is a clean and stable power that’s suitable for sensitive technology.
An inverter also uses variable speed, so it throttles up and down to meet your power demands. It produces enough power to run appliances, but as you add more load, the engine will speed up to make more power. When this happens, the machine suddenly gets louder.
A generator makes consistent power that’s ready to use. As you plug in your appliances, you simply draw power from it, and it maintains what it produces. Portable inverters are typically smaller, easier to move around, and usually quieter than portable generators.
With its open frame, the Champion Power Equipment 100520 8750 Watt DH Series inverter is a good option for home use or outdoor adventures where you want something quiet.
Description and Specifications
The Champion 100520 has a 4-stroke, 420cc, variable engine. Champion describes this 100520 8750W gas inverter generator as 30% quieter and 25% lighter than a traditional 7,000-watt portable generator. It uses quiet technology with a digital inverter to create clean power and less noise.
It also has automatic low-oil shutdown, a handy electric push-button start with a battery backup, and Cold Start Technology for easier and faster winter startup. This is essentially a recoil or pull-start and a choke valve. The valve “chokes” the air supply and changes the fuel-to-air ratio, which makes more fuel available to the engine for an easier start.
The inverter also comes with battery charging cables, a flexible oil funnel, and a USB port adapter so you can charge portable products like your smartphone or tablet.
Product Dimensions and Weight
The machine measures 26.6 by 25.6 by 23.7 inches. It’s small enough to store in your garage, a job trailer, or your truck box.
The inverter weighs 154.4 pounds, which is lighter than traditional generators of roughly the same size. You won’t carry this around with one hand easily, but it comes with a folding handle for moving and storage.
Power Consumption and Power Output
The Champion 100520 has 8,750 starting watts and 7,000 running watts with an output of 120 and 240 volts. It also has a 120-volt GFCI output for ground fault protection in damp conditions and a 12-volt supply.
This machine’s digital inverter components make it suitable for powering your appliances and technology like TVs and computers. These electronics have complicated controls, so they’re sensitive to disturbances in power supply. Electronics draw in short pulses of current, which become distorted and cause harmonic currents to flow back into the power system.
These disturbances are measured as total harmonic distortion (THD), which shows how much of the voltage distortion is caused by harmonics in the signal. You want THD to be as low as possible for your devices. Where generators give off about 15% THD, inverters give off less than 3%, making them ideal clean power for sensitive tech. The GFCI outlets also protect your devices.
This inverter also has an Economy mode that lowers noise and increases fuel efficiency during operation. Eco mode causes the engine to idle during periods of non-use or lower electrical output. Once the electrical load is connected or increases, the engine speed will return to normal and run continuously.
The Power of Champion’s Quiet Technology
The variable engine speeds mean inverters run at quieter noise levels and only speed up and get louder as more power is required. Combine the variable speed with Eco mode, and the machine is 30% quieter than a portable generator, even with its open frame.
This Quiet Technology allows you to use the inverter in noise-sensitive places like in the city or campsites with noise restrictions. It’s also useful for a power supply on small maintenance or jobs where you need a quieter option.
Champion has a three-year limited warranty after purchase date on mechanical and electrical material and workmanship defects. The warranty includes a fair use policy, so it doesn’t apply to normal wear and tear.
The warranty also doesn’t apply to damage from overloading the machine, modifications to the machine, misuse, improper connections, incorrect assembly, or poor maintenance. If you don’t take care of the generator or don’t use it properly, Champion won’t cover any resulting damage.
Items that normally have to be replaced like filters and O-rings aren’t covered. The limited warranty also excludes accessory parts like storage covers and starter batteries, cosmetic problems like paint or decal defects, and problems from parts that aren’t original Champion parts. Champion doesn’t warranty inverters or generators used for prime power.
Fuel Economy and Type
The Champion 1000520 inverter uses regular unleaded gasoline with an 87 octane rating. It has a 4.2-gallon tank, which can last 10.5 hours on Eco mode at 25% load. It also has a 1.2-quart engine oil capacity and uses 10W-30 oil.
Control Panel and Outlets
The inverter control panel is user-friendly and easy to read. In fact, Champion calls it the Quick Touch Panel because of its simplicity.
The Intelligauge shows the frequency, voltage, and session run time, which gives you a good idea of fuel efficiency and how much you can power on a tank of gas. It also shows total run time or operating hours, which is important for monitoring your service schedule.
The outlets are covered and include a 12-volt DC automotive-style outlet; four 120-volt, 20-amp GFCI (5-20R) outlets; and a 120/240-volt, 30-amp locking outlet (L14-30R). The GFCI outlets are suitable for household appliances and devices, and the locking outlet is an RV outlet for powering your travel trailer. There aren’t any USB ports, but the inverter comes with a dual USB adapter that fits the automotive-style outlet so you can plug in directly.
The panel also has other features, including:
- Electric start
- Eco mode switch
- Output indicator
- Overload indicator
- AC overload reset button
- Low-oil indicator
- Fuel valve to turn fuel supply on or off
- Built-in fuel gauge
- Circuit breakers to reset and protect the generator
Compared to other traditional generators of the same wattage, this Champion Power Equipment 100520 8750 watt inverter is lighter with a smaller frame. It’s considered portable, but at 155 pounds, it’s too heavy for most to manually lift and move around. The handle makes it easier to move and store, especially on rough terrain.
The inverter comes with a wheel kit. Champion advertises the wheels as “never-flat tires,” but customers say they’re plastic wheels. The benefit is that they’re solid so they won’t go flat, but they also might not move very smoothly. Customers say the plastic wheels can’t support the unit very well and tend to bow out.

This Champion 100520 inverter generator has more pros than cons, but there are some drawbacks. Overall, the machine is easy to use with a long run time. Generators take a lot of fuel, but the Eco mode allows for fuel efficiency, so you get a long run time on a tank of gas at a low load.
This machine has enough wattage to power work site projects or large home appliances. It can run a central air system and several appliances at the same time. Although it’s fairly heavy, it’s light for the wattage and not too difficult to move and store. The open frame makes it easy to service and change the oil, which is a great feature.
The machine has a built-in fuel gauge on top that makes it easy to quickly check fuel levels. It will automatically shut off if it’s out of fuel, but the gauge helps you troubleshoot shut-off at a glance. The low-oil auto-shutdown is a major bonus. It’s easy to forget to add oil, so this feature stops accidental damage. The inverter is also CARB-compliant and EPA certified.
The biggest con to this machine is probably the noise. While the open frame makes it lighter and easier to service, the lack of insulation does make the machine loud. Champion describes it as a little louder than a vacuum, but this is likely while in Economy mode. The machine will get louder as you increase the load, but compared to a 7,000-watt traditional portable generator, the Champion 100520 is fairly quiet.
The plastic wheels are also a drawback, but these wheels are standard across competing brands.
