Top 10 Best Generators For Construction Job Sites (Reviews)

For contractors, having adequate power for your tools, lights, and other equipment is key to a job site that does not have power currently hooked up.

A portable generator is a great investment to keep with your crew to ensure that they have the power when they need it the most.

Finding the right generator requires some forward thinking. You will want to consider all of the tools your team may use at a job site and find out the wattages each takes.

Below are the best generators for a job site ranked and compared:

Westinghouse WGen7500DF

Westinghouse WGen75000DF Available on Amazon is a dual-fuel generator, that can run on gasoline or propane.

It is no surprise to see it again as one of my top generators for the job site. It is loaded with features that benefit those who are working on site all day.

The WGen7500DF is on the lower scale for this list, not that this is a bad thing, it was just my choice in this range. It still pumps out a good 7500 rated watts and 9200 peak watts to allow you to get through the work day with enough power to run multiple tools and equipment.

Weighing in at 194 pounds, this generator features non flat wheels and collapsible transporting handles to allow you to move the generator all over your job site with ease.

This is also great for moving it out of the rain during a sudden storm or storing it indoors at the end of the day.

To keep you running all day, you can take advantage of the dual fuel mode that allows the WGen7500DF to run on both gasoline and propane.

You can expect to get about 16 hours of runtime at 50% load on either fuel.

Covered outlets allow your vital generator parts to stay safe from dust, water, and debris that is common in any construction setting.

Best Generators For Job Sites: Buying Guide

How Many Watts Do I Need For Power Tools?

Power tools come in a large assortment of sizes and shapes. This makes for a wide variety of wattage demands that your particular job site may need. My suggestion would be to look at your inventory of tools that you have on a particular job site and check the wattage demands of each.

Add these up and account for a little extra just for emergencies and choose a generator based on that number.

Pay attention to starting VS running watts!

What About Chinese Brand Generators?

While chinese tools and equipment may seem like a gamble due to lower quality standards, I have seen quite a few chinese generators perform just as well as American made units.

If in doubt, always check their reviews and do some extensive research from first hand accounts before purchasing.

Conclusion - About This Guide

So now that you have seen my thoughts on the 10 best generators for job sites, it’s time for you to find out how many watts you will be using a choose a generator that best fits your power needs.

I always suggest to get a generator that can handle more power than you need because you would rather have it and not need it rather than need it and not have it.

Are you currently running a generator for your job site? If so, what size, and what appliances are you running with it?
