Discovering the Best Job Site Generator: Our Top 10 Picks

You never quite know what you’re going to get when you’re working on a remote job site. In some cases, electrical power may already be installed. In others, you’ll need to rely on a job site generator to operate your tools, lighting and other essential equipment.

Given the uncertainty in each situation, it’s a good idea to have at least one high-quality portable generator to support your crew. But with so many options available on the market, choosing the best model to meet your needs can be a challenge.

Below, we’ll consider the factors that should influence your selection and review our picks for the 10 best portable job site generators you can buy. Below is a table with our recommendations for the best job site generator.

Factors to Consider When Selecting a Job Site Generator

Wattage

Depending on the type of work your job demands, the total power needs of your tools and equipment can vary widely. The best approach is to complete an inventory of all the tools you might need on the job and add up the total wattage needed to operate them—at least the tools you’re likely to want to operate simultaneously.

Make sure the generators you consider have at least that much running wattage plus a little extra for emergencies and other unexpected circumstances.

Manufacturer

With generators (as with most products), you tend to get what you pay for. If possible, try to purchase a generator from a well-known brand with a solid reputation for quality and reliable customer support. If something goes wrong with your generator, you’ll want to be able to reach someone at the company to help you get it repaired or replaced.

That said, there are some impressive up-and-coming brands on the market that don’t have widespread name recognition yet but still put out a quality product. Do a search for online reviews of the make and model you’re considering, and if you don’t see any red flags, go for it. If you can’t find any reviews or information about the brand, it’s probably best to steer clear of it for now.

Efficiency and Runtime

Fuel isn’t cheap, and saving money on the up-front cost of an inefficient generator can really cost you in the long run. Additionally, having to constantly stop and refuel the generator is inconvenient and wastes time you could be spending completing the job at hand.

When comparing models, check the fuel tank size and runtime stats to make sure you’ll be able to get in a solid work session before needing to gas up.

Portability

As a rule, generators are heavy pieces of equipment, with most averaging between 200 and 500 pounds. Because you’ll be moving the generator from job site to job site, it’s critical to find a model that’s as portable as possible. Look for included folding handles, sturdy wheel kits and other mobility tools that will reduce the hassle of transporting it.

With those factors in mind, take a look at the list of job site generators below, which represent some of the best performance, quality and value you’ll find on the market today.
