8500-watt Generator Reviews
1. Westinghouse WPro8500 Super Duty Industrial Portable Generator – Overall Best
Fuel Source:This Westinghouse WPro8500 is a portable gas-powered generator.
Start System: You can either turn on the generator manually, electrically, or remotely. There is a simple pull cord mechanism for a recoil start. For an electric start, there is a 3-way ignition switch. And with remote, you can easily turn on and off your generator from up to 109 yards away.
Engine and Output Power: The 457cc Westinghouse 4-stroke OHV engine can produce 11500 watts of peak power and 8500 watts of rated power.
THD Rating: It is safe to power your sensitive electronics as the generator features less than 5% THD rating. THD is Total Harmonic Distortion that determines the percentage of distortion present in a signal. The lower the percentage is, the better it will be for smartphones, tablets, and PCs.
Tank Capacity and Runtime: Westinghouse WPro8500 can run up to 17.5 hours on a 6.6-gallon gasoline tank. The automatic idle control feature helps the engine to idle down when no load is applied. This helps in saving fuel and extending the runtime.
Power Outlets: There are two 5V USB ports, one 120V AC 30A outlet, and one 120/240V AC 30A outlet. Also, we have four 120V AC 20A GFCI-protected outlets.
GFCI (Ground Fault Circuit Interrupter) is a circuit breaker that breaks down the circuit when it senses an imbalance between outgoing and incoming current. GFCI protected outlets are for the safety of the users. They protect them from electric shocks.
Certifications and Warranty: It is an EPA (Environmental Protection Agency) and CARB (California Air Resources Board) compliant unit, and has a 3-year limited warranty.
Weight: The weight of this WPro8500 is 192 pounds.
Operational Sound: Its operational sound is not mentioned.
Portability: For easy transportation, there is a lifting hook included, a foam grip fold-down handle, and two never-flat tires.
Other Features: The other features of this generator include; a fuel gauge, automatic low oil shutdown, and VFT data center.
Fuel gauge helps you to check the fuel levels. Automatic low oil shutdown feature shuts down the engine in no time when it senses the generator is running out of oil. And the VFT data center not only displays the real-time performance but also keeps you up to date with maintenance intervals.
2. DuroMax XP8500E Gas Powered Portable Generator – Best Lightweight 8500-watt Generator
Fuel Source:DuroMax XP8500E also runs on gasoline.
Engine and Output Power: It is powered by a 16HP fuel-efficient engine that generates 8500 surge watts and 7000 continuous watts.
Tank Capacity and Runtime: Its 7-gallon gasoline tank capacity is a little higher than the Westinghouse WPro8500. And with this fuel capacity, XP8500e can give a runtime up to 8 hours at 50% load.
The idle control feature helps you to save fuel to get better runtime.
Start System: Electric and recoil start are the two start mechanisms featured in this generator.
Operational Sound: DuroMax XP8500E operates at 72 dB (A).
Power Outlets: The control panel of DuroMax XP8500E is featured with four 120V 20A GFCI-protected outlets, one 120/240V AC 30A twist-lock outlet, and one 12V DC outlet for battery charging only.
Certifications and Warranty: Its warranty period is of 3 years, and it is an EPA and CARB approved generator.
Weight: XP8500E weighs around 130 pounds that makes it lighter than Westinghouse WPro8500.
Portability: Two durable tires and drop-down handles make transportation easier.
Other Features: A voltmeter is there along with a voltage selector switch and a low-oil shutdown sensor. Also, there is a fuel gauge and a built-in spark arrestor.
The voltage selector switch is powered with DuroMax MX2 technology that allows you to switch between full 120V and 120V and 240V at the same time. And the built-in spark arrestor prevents sparks from coming out of the muffler that allows you to use the generator in parks.
3. Champion 8.5-KW Home Standby Generator – Best 8500-watt Standby Generator
Start System: A 24V automatic start system allows the generator to turn on when the power goes out. No matter whether the temperature is -22 F or 104 F, the generator will turn on automatically without a need fora warming kit.
Also, the unit performs self-diagnostic tests on a weekly basis to make it ready to power every time.
Engine and Output Power: It is featured with a 439cc Champion OHV engine that generates 8500 continuous watts on propane and 7500 continuous watts on natural gas.
THD Rating: Champion 100177 is quite safe for delicate electronics as its THD rating is lower than 5%.
Transfer Switch: There is a sub-panel style 50A transfer switch that comes with eight available circuits.
Fuel Consumption: If you are running your generator on propane, then it will consume 1-gallon per hour at half load and 1.5-gallon per hour at full load. But the unit will consume 97.5 cubic feet of natural gas per hour at half load and 139.8 cubic feet per hour at full load.

Portable vs. Standby Generator
First, decide whether you need a portable or a standby 8500-watt generator.
Portable generators are useful in the sense that you can transport them anywhere. You can connect them with your RVs or move them around your construction or job sites. On the other hand, standby generators are connected with a home transfer switch to turn on automatically when the power goes out.
Standby generators also work quietly, but they are expensive than portable generators.
Tank Capacity and Runtime
You will always get a big fuel tank with an 8500-watt generator, but if the unit is fuel-efficient, then it will give excellent runtime; otherwise, you will not be able to run your generator longer.
It is not fair to expect from a conventional portable generator to run quietly. But some units can operate at lower decibel ratings. It is always recommended and beneficial to go for a generator that is not loud. Your unit must operate at less than 70 dB (A).
But in case of a standby generator, you will always find generators with lower decibel ratings.
Make sure your 8500-watt generator power outlets are according to your needs. To utilize thefull power, these 8500-watt portable units come with a variety of outlets. Make sure you have two or four 120V 20A household outlets and a 30A twist-lock outlet. Also, a 120/240V outlet is a plus along with 12V DC outlet and USB ports.
Also, double-check your generator has some safety features that are meant to protect it from damages. These include a low-oil shutdown sensor, overload protection, and spark arrestor.
