The question is: which generator is the right choice for you?

With many models offering similar features, it can be difficult to narrow your choices down to just one. Here are some things to keep in mind when comparing models:

  • Size and Weight: Portable generators are smaller in size and lower in weight than their full-size counterparts, but they can still be quite heavy and big. Check the product description to find out the dimensions and weight of the generator. Some can be as light as 60 pounds, while others can be 100 pounds or more. Choose a size and weight that suits you.
  • Capacity: How big is the gas tank, and how many hours of power will the generator provide? These are two important things to consider when buying a generator because you need a model that can keep you powered for however long you need. Many models on our list can go for 10-12 hours at 50% load and 7-8 hours on 100% load, which is more than enough to keep you running throughout the night.
  • Outlets: What type of outlets does the generator provide, and how many? Make sure the model you choose has the right receptacles for your power needs.

Buyer’s Guide – How to Choose the Right Four Thousand Watt Generator for You

Whether you need a generator for emergencies, recreational use, or a job site, it’s important to make sure you chose a model that can meet your power demands. We talked about some important things to consider earlier. Here are a few other points to keep in mind:


  • Low Oil Alert: Many generators have a low oil alert system or a system that will shut the generator down if oil levels get too low. This is a great feature to have because it helps protect the motor from damage when oil levels are low.
  • Voltage Meter and Circuit Breaker: Most models also have voltage meters and circuit breakers. The meter helps you keep an eye on how much power you’re using, so you don’t go overboard. And the circuit breaker resets the power just in case you do.
  • Wheels and Handles: Does the generator have a built-in handle or come with wheels? Wheels make the unit more portable, and are especially useful for heavier models that may be difficult to carry. If the unit has wheels, make sure it also has a handle for easy maneuverability.
  • Noise: Some generators are noisier than others. Check the product description for noise-level information, which should be listed as decibels (dB). The higher the dB, the louder the unit.
  • Cost: The cost of the generator is also important. Generators can be expensive, especially the powerful units. But always remember that quality should be considered above the cost of the unit, as a poor-quality generator may fail when you need it most.
