 Five important factors to consider before buying a generator

Fuel tank capacity

Before shortlisting the generator, you must check whether the generator is fuel efficient or not. It is a waste of money if the generator fails to produce the expected power outage for the fuel consumed. So, you must look for features like a smart eco-mode in the generator. It will reduce the engine RPM based on the load connected to it. So, you can increase the runtime and conserve fuel.

Power requirement

Decide the power demands of your appliances before choosing the generator. If the total power demand during power cuts is 4000W, look for a generator that produces a running wattage of 4000W. e.g., Sportsman 4000W generator

Fuel type

For a generator, gasoline and propane are the major fuels used to run the generator. So, you can switch between two options based on fuel availability. Since gasoline has a shorter lifespan, most of them prefer using propane.


Prefer placing the generator in an open space. On the other hand, there is CO built-up around the generator While using gasoline. So, ensure whether the generator room is provided with proper ventilation.


Generally, warranty varies based on the manufacturers as well as generator type. Check what is the defect coverage within the warranty duration.


We hope that you have got an idea about the 4000W generator specifications and features. In addition, the buying guide will help you to buy the best generator for the invested money. For best offers, you can place your orders on eCommerce sites.
