Buying Guide of 4000 Watt Generator

You might have made up your mind to invest in the best 4000-watt generator.

Prices, features,  running time, and power capacity are some important factors to consider. Check our buying guide to understand your power needs.


Fuel Type

A maximum of the generators support gasoline fuel type. Most of the generators come with gasoline fuel-type features. There are many reasons for the popularity of this fuel type. First, it provides good wattage and is cheap to buy compared to the other fuel type.

But gasoline has its disadvantages too. Sometimes, it becomes hard to find this fuel type.

Some generators have dual fuel features.  It means you can either run the generator on propane or gasoline. The dual fuel option saves in time of emergency when you run out of gasoline. That’s why we suggest you prefer a dual-fuel generator.


Fuel Capacity

For better fuel capacity, you need to balance your fuel capacity with the generated load. So, run a generator on 50% or 25% load to get maximum running time. But as you know sometimes power cuts stay longer than 12 hours, and a few generators provide 12 hours of running time, so it is advised to choose a long-running time generator. If a generator is fuel efficient,  it is an extra plus point.


Size and weight

Determine the perfect size of a generator for your needs. Size depends on your power requirements. If you want a heavy-wattage generator, it would be bulky. Like most of the 12000-watt generators, they are heavy and bulky.

If you need a generator for outside purposes,  choose a 1000-watt to 1500-watt generator.  it will be lightweight and perfect for adventure needs.

We suggest you get a wheel kit and handles if you choose a heavy generator. This wheel kit helps you transport the generator easily.

Weight should range from 60 to 100 pounds. You can exceed the weight if you think you can manage a heavy generator.



Different outlets are required to power multiple appliances. But we think these outlets are necessary for every generator.

One 30 amp for the power fridge. USB port to charge the phone and other devices.

A 12-Volt Dc port and a suitable RV port.

An Rv port is necessary if you live in an RV. Go more off the grid and make life more adventurous.


Noise level

the noise level of a generator is another important step. Anything between 60dba to 70dba is a desirable noise level. Some high-wattage generator makes a lot of noise. We suggest you go with inverter technology because such generators are quieter than the traditional model.


Other Important features

We are going to mention a few of the important features. Try to get a generator with the following features.

  • Low oil shut – protects generator.
  • Automatic voltage regulator – saves equipment and devices from damage.
  • EPA and CARB are compliant – Environment friendly.
  • LED display – for monitoring running time
  • Cold start technology – helps to start the generator in cold weather.
  • Electric start feature: enables you to quickly start the generator.



You want a generator that will run smoothly for a long time.  Right? But sometimes,  it is hard to keep them running unless you get a maintenance service for your generating. A long warranty period can help in this case. If a generator has a warranty period,  you do not have to pay extra expenses as this will be covered through brand support.
