Who Should Get This?

Why would someone need a portable generator? What sort of situations would it be helpful in? Here are several ways that having the best portable inverter generator would be useful and extremely helpful:

  • Campers – if you enjoy frequently taking a weekend here and there for a quick wilderness retreat, or if you are a die-hard camper that wants a little more flexibility in what you can use in camp, then one of our picks could make your getaways more enjoyable. Power fans, lights, music, or even electric cooking equipment.
  • Tailgators – if you are one of those people that find half the fun of going to games is the pre-game in the parking lot, then these are ideal for you! Save the battery of your vehicle while making your tailgating setup the envy of the visitors—plenty of wattage for music, and even electric grills, deep fryers, pizza ovens. Change the tailgate landscape!

Great for emergency use, supplementing existing power, or allowing you to bring power farther from home than before. Ideal for using electric landscaping equipment away from home.
  • Storm or Disaster-Prone Areas – if you live in an area frequently affected by severe storms, hurricanes, tornados, or rolling blackouts, these portable generators can literally be a lifesaver. Generous run time and output ensure that you will be able to keep cell phones and radios charged to help communication, keep a sump pump running to help with flooding, and can also help keep your refrigerator or freezer operational to prevent food loss and spoilage.
  • Craftsman, Trade Workers, and Handymen – if your job frequently requires you to be performing work at different locations, these units are a perfect solution. Throw one in the back of your vehicle, have portable, steady power for all power tools you need to get the job done quickly and effectively. Great for running saws, drills, nailers, light-duty welders, and more.

How We Picked The Best Portable Inverter Generator

If you need significant power in a reasonably compact form that is easily portable over small distances, then you are in the right place. What follows are some categories we used to objectively evaluate these generators. While they are not the only criteria, they are some of the most useful.

Running Wattage/Peak Wattage

These are the limits for how much power the generator can supply on both a continuous and a surge basis. The running wattage is how much wattage can be supplied for a load that is steadily drawing power, and the peak wattage is how much power can be supplied for a short time before causing a fault. Oftentimes appliances like power tools require a much higher power requirement to start up.


When evaluating anything that is supposed to be portable, weight is a critical consideration. A few pounds either way can be the difference between having a portable generator that you love to bring along for any project or need and being reluctant to use it because it is such a pain to lug it around.

Noise Level

Another essential thing to consider when making your decision is the noise level of the generator. There is a spectrum of noise levels that run from whisper quiet to having to shout for conversation if it is on. Generally speaking, the noise level is one of the things that fluctuate with the price point. High-end models will often have very manageable noise levels, whereas budget units may have to make the sacrifice of having a higher dBA rating.


This is certainly a factor that comes into play when selecting the best portable inverter generator, though it is usually not one of the “make-or-break” features. Some generators will have a variety of outlets that includes one or two AC outlets, DC outlets, and occasionally USB outlets as well, for charging your devices directly. Other units may only have limited outlet configurations, so that power strips or multi-outlet extension cords may be needed, depending on the needs of your situation or project.

Displays Or Readouts

This includes digital displays, fuel gauges, warning or indicator lights. A fuel level indicator is a fairly standard display on just about any generator. Still, some models also include things like a load or draw display, low oil indicator, overload or fault indicator, and output indicator.

Fuel Capacity

The more fuel your generator can hold, the less often you will need to refuel it, and the longer it will run. However, the extra fuel will cost weight if you plan on carrying or transporting it while it is full. Most models will have similar capacities, though even a small variance can mean the difference between refueling now, or two hours from now, or the difference between finishing your project or task or having to get more fuel before you can finish.

Run Time

Run time is an essential thing to factor in when making your eventual choice. The run time is the approximate time that the generator will operate at a given load percentage, with a full tank of fuel. Frequently run time is calculated with either a 25% or a 50% load.
