5000 Watt Generator Buying Guide

Inverter or Standard

One of the biggest considerations you’ll need to make when choosing a generator is whether you would like an inverter generator or a standard generator. 

A 5000 watt inverter generator will produce clean electricity that is safe to use on sensitive devices, such as smartphones, computers, televisions, and more. This is because inverter generators convert the current from AC to DC and then back to AC, which reduces potentially damaging harmonic distortion. 

The advantage of using an inverter generator is that they can be used on a much wider range of devices because they produce clean electricity. Inverter generators are also much more fuel efficient, because they don’t need to produce as much raw power as a standard generator. 

This means you’ll save money on fuel in the long run. Since these generators do not use very much fuel, they do not need large fuel tanks, so they’re typically much more portable than a standard generator. 

They also are much quieter because of the way that they run. 

However, inverter generators are typically more expensive because of these additional benefits they offer. This means that a standard generator may be a better choice for you if you are on a budget. 

Standard generators also produce more raw power than inverter generator, so if you’re more concerned about the amount of power than the type of power you’re getting, they might be the right choice. 


Another key consideration when selecting a generator is the type of fuel that it uses. The type of fuel your generator uses will affect the type and amount of maintenance you will need to do in the future. 

You’ll also want to look at the way that the generator uses fuel. There are now many fuel efficient generators on the market that are designed to preserve power and energy. 

Additionally, you’ll want to look for a generator that offers a low oil shutoff, as this prevents damage to the fuel tank in the long run. 


Many generators run on gasoline, which is very affordable and easy to find. The advantage of a gas generator is that you’ll be able to find affordable fuel virtually everywhere you go. 

However, they aren’t always clean burning, and they can be very loud. 


A 5000 watt propane generator could be the right choice for you if you are looking for something that’s going to burn cleanly and won’t have a harmful effect on the environment. 

While propane is more expensive than gasoline or diesel, it also burns much more slowly. You can purchase cans of propane to keep on hand in case your generator runs out of fuel. 


A 5000 watt diesel generator is a great choice if you’re looking for something long-lasting. Diesel generators are very durable and don’t require much maintenance to stay in good condition. 

Diesel is also very easy to find and is one of the most affordable fuel sources available, so you won’t have to worry about not being able to find fuel while you’re traveling. 

However, diesel isn’t a clean burning fuel source, so it isn’t as healthy for the environment. Like gas generators, they can also be very loud and disruptive. 

Dual Fuel

A dual fuel generator is a generator with the capability to run two different types of fuel. Usually these two fuel sources are gas and propane, although it can vary between models. 

Dual fuel generators are excellent because they are very versatile and have the benefits offered by two different fuel sources. 


A 5000 watt solar generator is an eco-friendly way to generator extra power. Solar generators are an excellent option if you live or travel in an area that gets sunny weather regularly. 

The biggest advantages of solar generators is that they don’t produce any emissions, and you won’t need to spend money on fuel. 

However, they may not be the most effective choice if your area doesn’t get much sunny weather. They also can be more expensive than other types of generators. 

Noise Level

Generators can be very noisy and disruptive, so when you’re searching for your 5000 watt generator, the noise level is something you’ll want to take into consideration. 

Noise level is measured in decibels – a normal conversation is around 60 dB, while a loud concert or motorcycle engine can be above 90 dB. 

The quietest generators are under 60 dB, so they won’t be too intrusive while you’re having a conversation. 


Portability is another important thing to consider when selecting a generator, particularly if you’re planning on using it while traveling in an RV. 

Consider both the size and the weight of the generator to ensure that you can comfortably carry it and that it will fit into storage when you aren’t using it. 

Many generators also come with wheels and handles, which make them much easier to move around. We are big fans of this kind of generators, so we wrote a best portable generator reviews guide that you should check out.

Pricing Range

Of course, price is also an important factor to consider when selecting a generator. 5000 watt generators can range widely in price, with the cheapest models starting around $300 and the most expensive models priced at over $1000. 

Factors like the type of fuel used can affect the overall price of the generator. While there are very good affordable generators, you won’t always want to go for the low price generator – instead, you’ll want to look for the model that offers the best value for money.

Frequently Asked Questions

Q: What Can I Run With a 5000 Watt Generator?

A 5000 watt generator can typically run one to two large appliances, or several smaller appliances. This includes things like small heaters and fans, fridges, hair dryers, and more.

Check to see how many watts of power your appliances use before plugging them in – as long as the total wattage doesn’t exceed 5000, the generator will power it.

Q: Will a 5000 Watt Generator Run a Welder?

A 5000 watt generator can run most 120V welders with no problem, especially if you are only running them at a half load.

However, they typically don’t provide enough power for a 240V welder.

Our Verdict

With so many great models on the market, choosing the best 5000 watt generator for your needs can be tricky. We recommend looking at many different factors, including power source, noise level, portability, and more to decide what’s right for you.
