Things to Consider

It would be a mistake to think that selecting a 6500-watt generator is easy. There are multiple nuances to the selection process that if you get one wrong, you may end up with a device that doesn’t work for you. However, if you get everything right, your purchase may even have additional benefits to what you were expecting. For this to happen, we have provided the buying guide below, so you know everything you need to check for.

Benefits of a 6500-watt generator

Owning a generator may be a necessity in some areas owing to the frequent storms and power outages that follow them. The 6500-watt generator is strong enough to power your home appliances until the power comes back on. This is inclusive of the fridge, TVs, microwaves, AC systems, and more. With more power-intensive appliances such as a fridge, you can power them for a while then unplug them so fuel can last longer. The generator can also be useful in an office setting provided, not that many devices are plugged in. As such, you can continue with your work even when the outside world is in darkness. But if you rather need a less powerful machine then there is a large variety of other generators, like for example, 5000-watt generators which have close characteristics to 6500-watt models, but there are even 1000-watt generators mostly meant for shorter trips and small gadgets to be charged.

Features to consider when choosing a 6500-watt generator

6 Best 6500-Watt Generators - Reviews and Buying Guide

If you want to tell apart a bad generator from a good one and a good generator from a great one, all you need is to look through the features. Most manufacturers will list the features included in each device on the package. This information is also freely available on vendor sites where the top-rated 6500-watt generators feature. As an authority vendor site, the same is true for Amazon, as well. Nevertheless, you may not fully comprehend what it means for a generator to be an inverter type over the conventional model. Also, you may need to differentiate between peak and rated watts.

These are all areas covered and explained below, so you know what each feature listed on a device entails and whether you need it or not.

Type of generator

Once you get familiar with generators, you will realize that inverter and conventional type generators are the two common types of generators in the market.
Both of these types of generators are portable, and this is made more so by the fact that they mostly come with wheels. They also work by burning fossil fuels such as gasoline, propane, or diesel.

In an ideal situation, the conventional 6500-watt portable generator will have about 3600 rpm, which will then output 120 volts at a frequency of 60 hertz. However, conventional generators are not perfect and end up having less than the required rotations. This results in the fluctuation of energy produced. As such, if you plug in some devices such as laptops, phones, and cameras, you may risk damaging them as they require a more stable electric current.

An inverter generator is a bit different from the conventional one mentioned above. It has more components, as well. Once power is produced in an AC format, it is converted to a DC using a component known as the alternator. An inverter then follows up to turn the electricity back to AC. Because of these steps, the electricity produced by the device is much more stable, and you are better off using this for your smaller appliances. These also have the general advantage of being quieter than their counterparts in operation.

You will also note that some generators only work with a single type of fuel, whether diesel, gasoline, or any other. These are the single-fuel generators. Others are hybrids and may also be known as dual-fuel generators since they provide the same level of performance with different types of fuels.

Peak/rated watts

While peak and rated watts are mentioned in the same breath, they mean different things.

Peak watt output is the highest power output that the device can provide. Rated watts means the output that the device will continuously provide under normal working conditions.
The Generac 5940 GP6500, for example, has an 8125 watts peak power rating. However, this only applies to the first few seconds after the generator has been turned on. 6500W is the device’s rated watt output.

Reliable engine

The most common type of engine to feature on the list is the (OHV) or overhead valve engine. These are often more compact than other types of engines, for instance, in comparison to OHC type engines. They also sometimes tend to be more powerful than their counterparts.

Fuel tank capacity and runtime

Fuel tank capacity generally tends to affect the runtime of the device directly. There are, of course, a few other factors involved, but the consensus is that the bigger the tank, the longer the runtime. With a big fuel tank and power economies like the one provided by the Generac 7683 GP6500, you can have as much as a 11.5-hour runtime at 50% load.

Available outlets

6 Best 6500-Watt Generators - Reviews and Buying Guide

How many devices do you want to plug into your generator directly? Answering this question should give you an idea of how many outlets you need. More is also better where this category is concerned. However, most devices mentioned above max out at six outlets, with some options even having fewer.

Starting system

Different 6500-watt portable generators have different starting mechanisms. Where a recoil starter is incorporated, you will have to start the generator manually. This is generally done by pulling on a starter rope or string and letting go. You also have the electric system that you can start up by pressing a button. Batteries are sometimes included to give the generator a starting jolt. These types of systems also often incorporate a recoil starter as a backup just in case the electronic startup fails. The remote start generator is as well just as the name suggests. You won’t have to go all the way to the location of the generator to start it up when you can do so from your current location.

Noise level

As you can see, each of the devices mentioned above has a noise level rating. It is widespread for people to install such devices around their homes. As such, it is preferred that they buy as quiet a machine as possible to avoid being disturbed by the noise. Nevertheless, most of the inventions will feature a noise level of 66 dB and above, so it is up to you to find a way to work around this.

Size, weight, and portability

6 Best 6500-Watt Generators - Reviews and Buying Guide

Of course, the size and weight are bound to be determining factors where the portability of the generator is concerned. Bigger is more often than not heavier and as a result, less portable. Nonetheless, most options come with wheels so you can have an easier time pushing them rather than carrying them. This is except for the Dirty Hand Tools 101092 generator.

Warranty

This is yet another area where you have to be careful while checking. A commercial generator should have at least a year’s worth of warranty coverage, while residential use should feature twice that. Of course, if you have the option of a more extended warranty, you should go for it without fail.

FAQ

For your safety and that of your loved ones, you should refrain from using your generator indoors. Fuel is combusted; hence, smoke and fumes are an expected result and may cause you to suffocate or get carbon dioxide poisoning. As well keep as far away from your vents, windows, and doors to also prevent this from happening.

The easiest way for you to do this is to incorporate the services of a certified electrician. However, some of you may not be all that willing to pay the extra cash for this to happen. If you feel the need to determine this yourself, you can list down the appliances that you need the generator to power. After that, check the starting power as well as the running power required for each of these devices and write it down as well. Calculate the total power requirement before going to the store. Remember that buying and plugging in a smaller generator than you need may be bad for both the purchase itself and for the other appliances it is connected to.

You have the option of powering up almost any appliance in your home so long as its power requirements do not exceed what the generator provides.

Our Verdict

The HONDA EM6500SX provides high starting power, relatively long runtimes, a sizeable fuel tank as well as technology that serves to protect devices that you plugin. As such, you can easily see why the generator was selected as the editor’s choice. The Generac 5940 GP6500 is as well one of the higher-performing, higher power-producing devices on our list with a starting power of 8125 watts. As well circuit breakers are included. Despite being a conventional generator, the low noise production by the generator is something to write home about.

Another favorite is Pulsar G65BN. It accepts both LPG and gasoline as fuel options and is more economical on fuel than other such conventional generators in its class. You may like Generac 7683 GP6500 as well for its high peak power output and large fuel tank, which is your right since you are more familiar with your needs than we are. In fact, each of the devices mentioned above may serve a specific need that others cannot fulfill; hence, it is up to you to choose the machine you end up purchasing. And please keep in mind that 6,500 watt generators are also being made by other respectable manufactures, like for example best Predator generators or Ryobi generators have lots to offer, so if you would like to extend the comparison in order to make the best choice, you are most welcome.
