Features of the best WEN generators

WEN 56203i Super Quiet 2000-Watt Portable Inverter Generator w/Fuel Shut Off, CARB Compliant, Ultra Lightweight

When shopping for a new generator, there are certain factors to consider to ensure the model you choose is the most compatible with your needs.

Some larger models might be overkill and not at all cost-effective to occasionally run a single appliance.

Conversely, too little power, and you will not be able to operate all of the necessary appliances.

Power Output

Generator power is measured by watts; each model has two numbers.

The first is the surge power, sometimes known as peak or startup power.

It is the greatest number of the two as it details the number of watts the generation to start. This current quickly decreases as the rpm of the motor increases.

The resting point is known as running or rated power. It is the wattage at which the generator continuously runs and determines the number of appliances it will power.

An inbuilt circuit breaker ensures the motor doesn’t become overloaded and trips, preventing accidents.


Most generators run on gasoline, some run on propane, and one of our features generators run on dual fuel, switching from one to the other with ease.

Fuel economy determines how long a generator will run on each full tank; therefore, tank size and capacity should be considered.


No-one expects a generator to run silently, but in the event of a power outage, it is nice to know that it won’t drown out all conversation and the sound from the television.

WEN generators display their sound output in decibels; most are considerably quieter than their closest, more expensive rivals.


Some of the most compact generators weigh between 35 – 50lbs, ensuring they are relatively easy enough to transport and store.

Some of the more powerful models often have a wheel kit, if not included, available as an add-on. A 100-pound+ generator is much easier to maneuver with a sturdy set of handles and solid, rubber tires.

CARB Compliant

A generator converts fossil fuels into electricity. Any appliance that does this process undoubtedly creates emissions that are unwanted and harmful to air quality.

During the 1990s, the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA) passed laws regulating generators and their emission levels.

All WEN generators are fully compliant in producing cleaner, high-quality power; always check that your model is acceptable for use in California.

Clean energy is safe to power more delicate electronics.


Your chosen generator should have enough ports and the correct voltage to power your appliances.

Some models feature voltage selectors to toggle between 120v and 240v, depending on the task at hand.

Safety features

An integral part of any piece of heavy-duty equipment has to be the safety features. Voltage regulators, low-oil indicator and shut-off, and overload protection are all advantageous.


Some of the models in our WEN generator reviews have 1-touch Eco-mode. The genny automatically assesses and adjusts the required fuel amount as the load is increased and decreased. Not only is this cost and fuel-efficient, but it also extends the life of your machine.

Where are WEN generators made?

WEN has been going from strength to strength since its humble beginnings in 1951.

Their inventory has steadily increased as they build on their mission statement to “help artisans around the world” and to “put the power into power tools”

Their Headquarters are in Elgin, Illinois, but finding out where their generators are made isn’t so straightforward.

Most information leads us to believe that they are built in China but pass rigorous testing in the USA.

Do not let the Made in China tag fool you. WEN generators rival other more expensive brands in performance, efficiency, and cost.

Which oil is best for a WEN generator

WEN 56225i 2250-Watt Gas Powered Portable Inverter Generator with Fuel Shut-Off, CARB Compliant

A generator is a hefty investment; for it to perform at its best, it requires regular oil changes.  Knowing which oil is best for your model depends on many criteria.

  1. Owner’s manual. For the best advice, always refer to the manual that came with the generator. It will direct you to to the best type of oil to achieve optimal performance and extend the service life of the machine.
  2. Engine type. Most modern generators have 4-stroke engines that run best with standard SAE 30 oil. If your preference is synthetic oil then 5W-30 or 10W-30 have similar properties. The numbers describe the viscosity and behavior of the oil at different temperatures.
  3. Operating temperatures. Using a generator in extreme weather conditions requires oil up to the job. SAE 5W-30 supports a variance of temperatures from as low as -20° through 100°f.
  4. Reputable brand. Cheap oil is usually cheap for a reason. A good brand of oil is always a wise choice to keep your generator performing well.

What is an Inverter Generator

Conventional and inverter generators both use fossils fuels to run an internal combustion engine, which, in turn, produces electrical energy.

They employ electromagnetic induction to induce voltage by cutting an internal flux.

Inverter generators work in the same way but with additional circuitry. It makes them the most superior.

Both types of generators create AC power directly. However, the inverter converts it into DC power and finally back to AC. The power produced is much cleaner, safer, and by far the most efficient.

Do WEN generators have air or liquid-cooled engines?

Any engine has to have a cooling system to prevent it from over-heating; generators included.

It usually takes the form of air-cooled with an internal fan and venting system, or liquid-cooled that relies on oil or a chemical coolant to control the temperature.

Although liquid-cooled engines tend to run slightly quieter, they require regular maintenance.

It is easier to care for an air-cooled machine; they are the less expensive option.

All WEN generators rely upon air technology to cool their engine.
