10 Best Portable Generators for Construction in 2021

Last Updated on March 13, 2021 by John Smith

There are a lot of problems with current portable generators, especially when using them for construction projects. These are the most frequent issues:

  • Lack of wattage to consistently power the most used tools in the construction industry (i.e. corded drill, impact drivers, etc…)
  • Low-quality components which substantially shorten the lifespan of the generators
  • Small tanks that provide an annoyingly brief running time
  • Noisy engines make the experience of working close to portable generators very unpleasant
  • Inefficient fuel/gas utilization shortens the running time and makes maintaining the generator more expensive

Due to all this, I decided to research and test lots of portable generators to arrive at a list of the best ones for the needs of a construction worker.

How Did I Test The Best Portable Generator for Construction?

For those curious, these are the tests I performed to select the best portable generators for a construction job site:

Power test

For this test, I made sure to hook as many corded tools a construction worker would use daily: corded drills, corded angle grinders,  etc…

In this context, the size of the fuel or gas tanks, the length of the running time, and the level of wattage were key for providing a solid stream of electricity to these tools, of course.

If the portable generator being tested consistently powered the formerly mentioned construction tools, then I would pick it and continue with further testing.

Convenience test

During this test, I paid attention to two main points:

First, I tested the portability of the generators. If they were too heavy to be moved around, then I’d discard them, I mean, we’re looking for the best PORTABLE generators for construction, right?

Then, I made sure to pick portable generators with powerful but quiet engines. No construction worker wants to spend their workday surrounded by a loud engine, so the noisiest generators were dumped during this test.

Durability test

This test is one many construction workers don’t pay attention to but that is crucial to avoid future headaches. Nobody wants to spend hundreds of dollars on a portable generator for construction workers that won’t last more than a few months.

This is why I made sure to test each generator by making sure it was backed by reliable brands and with solid components made of the best materials. In my experience, that’s the best method to get the guarantee your next portable generator is going to last for at least a few years.

Must-Have Features of The Best Portable Generator for Construction

Based on my experience, these are the must-have features a portable generator should have to perform best at a construction site:

Strong Wattage

Look, if you want to get a reliable portable generator to run all your construction power tools, then you better find one with a strong wattage.

Looking for a generator of at least 7500 starting watts would be enough for most construction workers. To be safe, I like to go for 10000 watts generators as you’ll be set, especially for running various power tools simultaneously.

Fuel/gas Economy

No construction worker wants to spend hundreds of dollars on a portable generator that quickly burns through fuel, right?

Well, in that case, I’d say that going for a portable generator with an efficient motor might be your best bet. Otherwise, you’ll be looking at thousands of dollars wasted on re-fueling generators that can’t run for more than a few hours.

Quiet Engine

Have you ever worked the entire day with a loud running engine right next to you? It sucks, right?

Well, if you wanna avoid this with your next portable generator, then you might wanna search for one with a quiet engine that runs around 52 to 62db.

Why that specific segment of decibels? Well, because, in my experience, that’s the noise made in a normal conversation.

Regular Voltage

Your power construction tools are weaker than you might think. I mean, a strong power surge could generate an internal shortcircuit completely wrecking these expensive power devices.

Thus, I’d recommend going for a portable generator that delivers a steady stream of regular voltage with overload protection. Thanks to these attributes, you’ll work the entire day knowing that your expensive power tools and gadgets are protected.

Portability

Working with generators is a bittersweet experience. You get the awesome experience of using your power construction tools in places where there is no power outlets available at the expense of carrying a huge, bulky, and unbearably heavy generator.

To improve this, I’d recommend construction workers to find a portable generator that’s under 300lbs. 

That way, you’ll have the guarantee that your next portable generator is gonna be both powerful and easy-to-carry-around. That’s a pretty good deal, huh?

Durability

I despise the feeling of spending hundreds of my hard-earned dollars on a portable generator that doesn’t wait more than a few months to start breaking down. I mean, what a frustration!

This is why I recommend other construction workers to get portable generators with the following features:

  • Manufactured by recognized brands in the portable generator field
  • Made with top-quality materials (avoid plastic parts as much as possible!)
  • Sold by companies with great customer service
  • Avoid overseas brands

Frequently Asked Questions

Lots of questions are asked regarding the topic of portable generators used at a construction site. This is my attempt to answer the most frequent ones:

What’s the advantage of aluminum enclosures of a portable generator for construction?

Well, construction sites are outdoors most of the time, meaning they don’t have roofs.

In that context, a portable generator used at a construction job site is gonna be exposed to the elements (wind, rain, humidity, etc). As a consequence, there’s a big risk these expensive portable generators could break down if exposed to, let’s say, a sudden rain.

This is where aluminum enclosures come in. These products appear as the perfect solution as they completely enclose portable generators keeping them isolated from the elements.  They might appear as an expensive solution at first, but they quickly pay for themselves when used at a construction site.

Pro-tip: If you’re thinking of running your generator indoors, make sure to have proper ventilation and CO detectors to avoid carbon monoxide poisoning.

Should I get Chinese portable generators for construction work?

Look. If you wanna know that your next portable generator for construction is going to be both powerful and durable, then going for an American made generator is your best bet.

However, there are some Chinese portable generators made with reliable components.

But the question remains, should I get them? Well, it depends.

If you’re willing to extensively test them, read their reviews, and do the proper research, then you’ll be able to find some good picks. However, if you don’t have enough time, then going for American made portable generators will be better for you.

How many watts does a portable generator need for running power tools?

The best way for me to answer this question is recommending you to follow the next guide:

  • Grab all your power tools and write down the wattage they need to be powered
  • List all the tools you’ll need to run simultaneously and add their wattage to know the max wattage you’ll need
  • Read the specific attributes of each portable generator (wattage, tank size, etc) and choose accordingly

Do portable generators for construction need maintenance?

As we all know, portable generators have engines. These engines, like in cars and trucks, need maintenance. 

I can’t give you a specific guide to follow to maintain your portable generator, you’ll have to find that in the user’s manual.

However, what I can tell you is this, if you don’t regularly put oil in your portable generator, you’ll soon find it won’t turn on. So, make sure to read the user’s manual and pick a quality oil for your specific brand portable generator.

What oil to choose for maintaining a portable generator for construction?

As explained before, it’s difficult to say what type of oil portable generator for construction workers need. That’s information one should look for in the user’s manual. 

What happens if the portable generator has a power overload?

Well, that’s an easy one to answer.

If a portable generator for construction gets overloaded, one of two things might happen:

  • If it has overload protection nothing will. Your power tools will remain untouched.
  • If it doesn’t have overload protection nasty things can happen. I mean, it could catch on fire, completely ruin power tools, break the generator itself, release chemical gases bad for your health into the air, etc…

So what’s the main takeaway here?

Get a portable generator with overload protection!

Can portable generators for construction replace electricity utility service?

They might. It all depends on the type of construction site we’re talking about.

If we consider small construction sites where 5 to 10 construction workers do their jobs, then using portable generators should be fine.

But, if we talk about massive construction sites where more than 50 construction workers work, then using the electricity utility service might be the best bet to get a reliable power source. It’s worth mentioning in some cases the electricity utility service is not available and these job sites end up having to juice their power tools with portable generators either way.

Also, generators are much more expensive than the utility bill, so that’s another thing to keep in mind.
