Buying Guide
When it comes to choosing the best 12000 watt generator, there are several factors to consider. In this section, we’ll go over some of the key features to look for when making your decision.
Power Output
The first thing to consider when choosing a 12000 watt generator is the power output. This is the amount of electricity the generator can produce, and it’s measured in watts. Look for a generator with a power output of at least 12000 watts, as this will ensure that it can handle all of your power needs.
Fuel Type
Another important factor to consider is the fuel type. Most 12000 watt generators run on either gasoline or propane. Gasoline generators are typically more affordable and widely available, but propane generators tend to be more fuel-efficient and produce fewer emissions. Consider which fuel type is most convenient and cost-effective for your needs.
Fuel Tank Capacity
The fuel tank capacity is another important consideration. A larger fuel tank means that the generator can run for longer periods of time without needing to be refueled. Look for a generator with a fuel tank capacity of at least 8 gallons.
Portability
Portability is also an important factor to consider. If you plan on using your generator for outdoor activities or events, look for a model that is lightweight and easy to move around. Consider the size and weight of the generator, as well as whether it has wheels or handles for easy transportation.
Noise Level
Finally, consider the noise level of the generator. Some generators can be quite loud, which can be a nuisance for you and your neighbors. Look for a generator with a noise level of 75 decibels or less, which is about as loud as a vacuum cleaner.
In summary, when choosing a 12000 watt generator, consider the power output, fuel type, fuel tank capacity, portability, and noise level. By taking these factors into account, you can find the best generator for your needs.
