Portable Generators Buying Guide Best Portable Generator For Construction

Suppose you cannot choose the right portable generator for the construction project. This buying guide will help you learn the factors you should consider while buying a great portable generator for the job site.

To ensure a silent environment, look for ultra-quiet generators after confirming your preferred kind.

By choosing ultra-quiet generators, you may relax without worrying about any extra noise pollution. Make sure to check that the generator is EPA and CARB-compliant.

Let’s get started with the first and most important factor, which is 

Portability:

Construction sites with labor working for 24 hours need consistent power backup, and the best option for such needs is a portable generator. The best generators are portable ones, which are small and can be kept even in your backup and used when necessary.

Some portable generators are light, but some are heavier as well. Choose the type and function of a Waterproof Portable generators based on your desired needs.

Although we discuss portable generators, some heaviest generators cannot be moved from one place without using a giant machine. So, all the portable generators discussed above can be easily carried away by one or two persons combined.

Wattage:

The next important consideration for buying a portable generator is the wattage requirement. Each generator has a preset wattage from which users select their preferred gadgets. It is the number of watts necessary for the power tools to function properly.

All the power tools on the construction sites must have mentioned wattage capacity. To confirm compatibility, review the description of the cost-effective generator. When the equipment is suitable, using the generator is simple…

Regular Voltage:

After deciding on the estimated and required wattage of appliances and generator respectively, the next big thing to focus on is the regular voltage. Typically generators are coming with the regular 12 V DC as the input voltage and the 120V AC as the output voltage. Those generators having 12V DC input can also be used for charging external batteries and be connected with car batteries for supplying power.

The 120V AC output is standard voltage in households and is quite convenient for use. It takes longer to charge your batteries with a 120V AC supply rather than 240V AC or more. There are many generators that feature 240V AC power output and there are a few high-end generator units featuring split-phase technology to offer both 120V and 240V AC output simultaneously.

The selection of voltage depends upon your requirements and if you have to switch between 120 and 240 Volt AC supply then you should opt for a split phase generator and for that purpose you should be ready to spend some extra bucks.

Quiet Engine:

The sound level of the generator is the foremost consideration for some consumers who take it as the deciding factor for determining which generator to buy. The sound level or noise coming from your generator is quite annoying if not for yourself then definitely for your neighbors. The generator noise of your generators is the most annoying thing you would encounter and the worst case is that you don’t find any solution for this buzz. There are plenty of great portable generators that have embraced noise-reducing technologies to give a reasonably bearable sound produced by the generator engine that gives a pleasant power experience when outages happen at home or during camping nights on the campsites.

Fuel/Gas Economy:

If you want to cut short on your utility cost a power backup tool may sound like a reasonable option but it is not always a wiser option as the running cost of your generator will be manifold than your electricity utility services. If you want to have the best of both worlds then choosing a fuel type with the affordable running cost is the way to go. But running cost is not entirely determined by the fuel type as generators operating on the same fuel can have different running costs.

This is because the two generators can have different fuel consumption rates or economies. When choosing a generator, it is always a wiser choice to go with a unit that has economical fuel or gas consumption rates rather than one with a skyrocketed price tag and high fuel consumption economy.

Ease Of Use:

A portable indoor generator should be easy to use. To prevent problems, choose the device that is easiest to use. The straightforward understanding and easy operation of the control panel are generated.

Some cheap generators only have one pull start; others may start quickly with the startup button, which is an extremely efficient way to start the generator. All you have to do is choose the one that best suits your needs.

Connectivity:

With a versatile ports generator, With more ports available, charging your phone, camera, and other devices is simple.

When buying the generator, you should carefully look at the output ports the generator offers. The best device will be provided if there are more intelligent USB charging ports.

With various connectivity ports, connecting many devices simultaneously is simple and ensures fast charging. As you are going to use the generator for power tools, make sure to check for the ports for the desired tools and the AMPs to avoid any inconvenience.

Quality:

You’ll be surprised to learn that I currently work on my laptop thanks to the robust, high-quality contractor generators that make it easier for me to complete my tasks if there is a prolonged power outage.

The high-quality gadgets guarantee extended endurance and protect you from any unpleasant power outage circumstances.

So choose the best, least expensive generators with the highest power standards if you want to continue working without interruption. Please choose the greatest portable generator that doesn’t sacrifice quality.

Built-In Material:

Although the generators are manufactured with a slid meta-like steel, you should still consider the generator’s material to get peace of mind. Some generators have both plastic as well as metallic parts onboard.

Depending on the environment you are going to use the generator, sometimes, there is a cover for the generator, and the scorching heat of the sun can damage the plastic components as well.

Safety:

Portable generators are safety devices that safely charge your delicate electronics without damaging them. They are not simply powered supply devices used in power outages.

To safeguard the security of your electronics and appliances, always choose a portable generator with a lock-on protection feature.

Overloading is a detrimental phenomenon not only for the generator unit itself but also for the power tools or electrical appliances connected to it. Modern generators have overload protection and if your generator has one such safety feature then nothing will happen if you overload the portable generator as the power supply will be shut off.  But if your generator has no such protection then your power tools may be completely ruined or your generator may break causing accidental fires including financial damage and even harm to life and property.

9.   Can Portable Generators For Construction Replace Electricity Utility Service?

Electricity utility services could prove to be an affordable or expensive option depending on your power requirements for construction sites. If we go with a small construction site with few workers let’s say 5 to 10 then a generator is a better option as it would reduce your running cost but if you consider a massive worksite with over 50 workers then a generator is not a reasonable choice and you should think about replacing it with electricity utility service.

As a matter of fact, you may not find electricity utility services available near the construction site and you would eventually have to end up with a generator supply whether you find it reasonable or not.

12. How Long Can A Job Site Generator Run Before Refueling?

The runtime of a generator is determined by its load and wattage. If you have a mid-range portable generator operating at its maximum load then a typical runtime is 8 to 12 hours for a mid-range wattage generator like 4500 watts unit. You can increase the runtime by decreasing the load such as the same 4500 watts generator can run for 12 to 14 hours on half of its maximum load.
