And with the best 4000-watt portable generator, it is much easier to have the power transported to wherever place you need it most.

Power requirement

Before you can do any search, do a little research on how much wattage you need. The calculation will require you to add the wattage necessary for each of your appliances or power tools, in terms of starting and running power for the motor-driven applications. That is crucial since the 4000-watt rating might be the starting watts or the running watts, and that wouldn’t be so great.

Portability

Portability will tell how easy it is to transport and store the generator. And since you might be needing a power source to carry with you while going for camping, RVing, or tailgating, you might want to buy a generator that has never-flat wheel kit and a handle for easy pulling or pushing.

Will you buy an inverter generator or a conventional generator? What is the difference? The two have one thing in common; they’re all designed to give you power. However, an inverter generator is a bit compact, lightweight, rugged, portable, and also low-noise, compared to the conventional one.

Which one will you buy?

Extras

Apart from checking the noise level of the generator, which needs to be lower than 70dBA, you also need to check on some features that will make it super easy to maintain and operate the generator.
