How to choose the best 7000-watt generator

Several things need to be taken under consideration while looking for a 7000-watt generator. You’ll need to check whether the generator’s price is within your price range, what is the tank size, what safety measures the generator has been equipped with. 

This article has taken into account the same factors. But if you want to do your own research, you should consider the following factors:

Step 1 – Consider the price

Whenever you are shopping for something, the first thing you consider is the price.

What you need to understand is that the most expensive unit is not necessarily the best. On the other hand, if you go for the cheapest option, you may save some money, but you may be faced with other problems in terms of quality and usability. 

So, the best option is to go for the middle ground. Choose something that fulfills your needs but is not loaded with unnecessary features that make it costly. And at the same time don’t go for something that will become useless in a couple of months. 

The best generator would be the one that fulfills its purpose and is also economical.

Step 2 – Consider the tank Size

Tank size determines how long the generator would be able to run. This makes it one of the most important points to consider before buying. And although you would like to buy the one with the maximum capacity, it comes at a cost, literally speaking.

Bigger tanks would increase the cost of consumption. Choosing the size of the tank, which suits your requirement would be the smart decision.

For example, if your requirement is for utilization of 4 hours, it would be best to buy a generator with a tank size of enough fuel to run five hours. The extra hour is to keep safe from any margin of error.

Step 3 – Take the noise level into account

Surely you don’t want to exchange the discomfort of electricity blackouts with a headache from the noise of your generator. So, take into account the level of noise being made by the generator you wish to buy. It depends on the circumstances and which situation suits you best. 

If the generator would be placed at a distance from where the noise would not be a nuisance, you may opt for the cheap, noisy one. 

But if you live in a populated area, it may end up causing trouble between you and your neighbors. And in this scenario, the courteous thing to do would be to buy a quiet generator, which would not contribute to the noise pollution which so infests the urban areas. 

And if noise control is a priority for you, there are a lot of options of generators that have quietness as a selling feature. One may think that an added feature would surely make it quite expensive. 

Fortunately, that is not the case, and quiet operation is usually an economic feature as well.

Step 4 – Think about safety

Poor use of generators may lead to serious injuries or even death. Safety should be one of the features to look for when buying a generator. A generator that offers protection and is not risky to use should be chosen. 

The use of generators mostly occurs during blackouts. The generators which offer protection against accidental spills should be chosen. Also, look for generators that reduce carbon monoxide emissions. 

Step 5 – Consider the run time

The runtime is a measure of how long the generator will run in one go. This depends on two factors; the size of the fuel tank and the efficiency of the engine. 

The run time also depends on the power that is being drawn from it at a time. The same generator will run for a longer period of time if a few appliances are being powered by it as compared to when it is being run at full capacity. 

The run time is also factored in by the quality of the fuel used. The run time on a typical generator ranges from 4-5 hours. Some even go as far as 10 hours. 

Step 6 – Check the outlets and portability

The number of appliances that you can run on a generator depends on the number of outlets that your generator has. The type of outlets available on a generator also determines the types of devices you can run. 

Usually, every generator has at least four 12A/120V standard household outlets. The kind of generator you choose depends on how you wish to use it. Whether it is for household use or to power up an RV, the number and type of outlets would be different. 

So, you should bear in mind your requirement while looking for a generator. Similarly, the portability of different models depends on how you plan to use it. 

The generator would remain in the same place when being used for household purposes. In this instance, portability would not be an issue. But if you need a generator for your RV or for occasional outdoor trips, carrying a gigantic generator can be problematic. 

In the end, it depends on your suitability. 

Step 7 – Consider usability

The ease of use is also very important to consider when looking for a generator. A generator with complex, technical dynamics to make it work would not be the preference for many people. So, choose a generator that is simple to use and maintain. 

Also, the more complex it is to use a generator, the more likely it is that problems will occur. For example, many people are not tech-savvy. They may mess up the settings while using a highly complex generator or may not be able to run it at the time of their need. 

Hence, it is best to use a generator that can be used by everyone.

How to use your 7000-watt generator properly

Some precautionary measures must be taken to ensure that your generator remains in the best working condition. Taking proper care would also extend the useful life of the generator. Some insight into the safe and effective use of generators is given below.

Never operate too close to your home

Manufacturers warn against the use of generators within or close to your house. The burning of fuel inside the generator results in the production of carbon monoxide. If the generator is placed within the house or close to it, the carbon monoxide will accumulate in the house. 

Carbon monoxide is a poisonous gas that, when inhaled, could be fatal. Many people die from running their generators in close proximity to their houses. 

Moving the generator away is a nuisance, and the extension cables are an added expense. But, it is much better than running the risk of carbon monoxide poisoning.

Refill after the generator has cooled down

The fuel tank is situated right above the engine so that the carburetor has easy access to the fuel. 

Due to this fact, refueling can be quite risky if you do not let your generator cool down. If you spill on the yet hot engine, it may ignite, and the fire may further spread to the rest of the fuel in the fuel tank. This could lead to a seriously injurious and catastrophic situation.

Run it on a surface level

Many generators have such lubrication systems, which work best on surface levels. If the generator is placed on an incline, the lubrication system is rendered ineffective as most of the parts of the engine cannot be reached. 

This could affect the functionality of the generator and may even damage it permanently. So, it is best to place your generator on a surface level. If you do not have a surface level to place your generator on, make one.

Limit cord length

To minimize the noise from the generators, they are parked far away from their place of use. That is fine, but to make sure nothing goes awry, premium-grade extension cords should be used. 

A heavy-duty, outdoor-rated extension cord would be best suited for this purpose. But even with this, the total distance should not exceed 100 ft. from the generator to the appliance. Longer lengths may damage your appliances during voltage drops.

Keep enough fuel to last the blackout

Suppose the generator runs out of fuel while underuse; the electrical load can drain the residual magnetic field from the generator coils. 

The generator may start after you refuel, but it would need to be repaired before being able to generate power. The magnetic field would have to be repaired before it can work again. So, to avoid going through that, make sure you have enough fuel in your generator to last the blackout.

Beware of bad fuel

Bad fuel is the major reason for causing problems in all fuel-powered small engines. All manufacturers suggest using a fuel stabilizer to reduce the risk of fuel breakdown and varnish buildup. 

However, this does not eliminate the risk entirely. The best way is to empty the fuel tank and let the engine run dry until it stalls. Fresh stabilized gas should be used in generators to keep them in great working condition.


What is the quietest 7000-watt generator?

The quietness of generators is a very important thing to consider, especially for those living in populated areas. Many manufacturers have risen to the need of the hour, and now a lot of options in quiet generators are available.

Honda’s EU7000iS is renowned for being super quiet while giving the best performance. 

Westinghouse WGen7500 is also a popular choice when noise minimization is a priority.
And, last but definitely not least, Ford 7 has made its name on the market as being one of the quietest generators.

Can I power my RV with a 7000-watt generator?

A 7000-watt generator has more than enough power to generate electricity for the appliances of an RV. You can power up the lights and water pumps and can also keep the kitchen of the RV running.
However, you must take note that large-capacity generators are also noisier. So, choose carefully how much power you need to work your RV without being a major nuisance.

Wrapping it up!

I hope by now you are somewhat of an expert on 7000-watt generators. 

I’ve covered all the important points. You now know how and what to run on your generators, how to choose the best one. You are aware of the leading units in the market.

Remember to be aware of your power usage before buying your own 7000-watt generator. It is an important and usually a one-time investment. You have all the information you would need before stepping into the market.

Be mindful of your power usage during a power cut. Yes, these generators are powerful, but not indestructible. You may also want to check our guide with the 10,000 and 2,000 Watt generators.

I hope you are now confident of making the best choice out there!
