When you need power in a pinch, a 3000 watt generator can help running power tools and even major appliances. You certainly can’t power you whole house, but finding the best 3000 watt generator for your situation can be a real life saver!

3000 watts is on the smaller end for generators, however at this output level, 3000 watt inverter generators are plentiful. For many applications inverter generators make a lot of sense – they provide “clean” power for sensitive electronic devices like cell phones and computers.

Check out some of the top reviewed 3000 watt generators perfect to provide that extra power when you are in a jam!

Note that 3000 watts falls within normal industry breakpoints. You can often find many around 2500 watts and 5000 watts, so a few below will not be exactly 3000 watts – but the idea is to find the best capable of producing around 3000 watts.

Best 3000 Watt Generators

When you’ve never bought a generator before, it can feel a little bit daunting to narrow down what will be the best option for you. 

After all, what exactly do you need to look for? You need not worry – here are some of the key things that you should think about when buying a 3000 Watt Generator.

Fuel Capacity

This may seem very simple, but the amount of fuel that your device is capable of holding can directly influence how long it is capable of running.

In general, when you’re shopping for a 3000 Watt generator you can usually anticipate a fuel capacity anywhere from 0.6 gallons to 5 gallons in total. There’s another thing to think about too – the larger the fuel capacity, the larger your generator will be. This means it’s not going to be as portable.

This is a pretty small price to pay when you think about it. After all, if the generator has a large capacity then it’s likely to last for much longer. This is especially important if you’re in an emergency situation and you need your generator to stay on for quite some time to keep your house powered up.

In short, if you have a generator that only has around a gallon of capacity, then the chances are that it will only give you a couple of hours worth of running time. 

Alternatively, a particularly large capacity could mean that your whole house can stay connected to electricity for as much as 20 hours in some cases.

Usually, fuel capacity is reported as a statistic in relation to a generator’s run time. For instance, you may find a generator that has a value of 25% or 50% output. If the generator’s output is higher then the fuel will drain much faster.

Fuel Efficiency

While the vast majority of portable generators are fairly fuel efficient, this is not the case with every single generator. 

Some generators have larger tanks than others, some fuels aren’t as efficient, and there are so many other variables that can impact the overall fuel efficiency of your units.

You’ll have to do some calculations to figure out how efficient your generator is, but it’s really just best to look at other things such as the capacity and fuel type.


Portability is certainly one of the most important factors to consider, especially if you intend to take the generator camping with you or if you are going to be using it in an emergency.

A generator doesn’t necessarily have to be small to be portable, however. For instance, portability could refer to handles, weight and the wheels.

Usually a lot of 3000 watt generators will weigh more than 70 pounds – this certainly isn’t light, but you can also find some that are close to 100 pounds. Not everyone can pick this up easily, so you’ll need to consider other things.

Certain things will influence the weight of the generator, such as bigger fuel capacities, more outlets or other things such as heat shielding. If you need to move your generator around a lot though, you should at least be looking for a generator that has a minimum of two handles. 

The handle should also telescope and having wheels is also pretty handy as you won’t need to lift the device at all if it has a good handle and some wheels.


This is an important consideration if you need the generator for something like camping. Certain generators like inverters are usually pretty quiet, to the point that you could easily talk over the noise without needing to scream and shout.

With that being said, manufacturers are often hesitant to state their noise ratings on their products. This is because nobody wants a really loud generator that will wake up their neighbors, or something that will keep you awake at night. 

In short, the best way to find out how noisy a generator is is to trawl through online reviews.

In general, most of the quietest generators on the market have a noise output of around 50 dB, though some of them can even be as loud as 75 dB. 

For camping and RVing, it’s essential to have the quietest generator possible, though this may not be all that important if you’re working on a construction site for instance.

Power Output Ports

When you’re buying a 3000 watt generator, you really need to think about the number of power outlet ports available. 

You should be looking at a generator that has two 120 volt household outlets at the minimum, though there are plenty of options out there with four or even more than this.

It’s also worth looking for generator that have extra special outlets, such as USB ports or biggest outlets. These can be pretty handy, especially if you need to charge a smaller device such as a smartphone. 120 volt household outlets are absolutely the priority, however.

Ease of Use

The last thing you want is to be spending the rest of your life trying to figure out how a generator works. It’s important to have a generator that’s easy to use, as it can impact how safe it is to use and ultimately how effective it is.

Some things to think about include the interface of the device, the instructions that it comes with, and the instructions that are printed right on the generator. You should also consider the circuit breakers as some of them can be much harder to use.

There are also certain generators that come with LCD screens, and these will show you key information that you need to know. Others come with things such as indicator lights. These are all big selling points that you should consider.

Safety Features

When it comes to electrical devices, it’s essential that you consider your safety. The last thing you want is to have an accident.

Some things that you should look for include exhaustcontrol, automatic shutoff and heat shielding.

There are some generators that also have an automatic low oil shut down system, and this means that the generator won’t work if the oil is low or if the temperature is too high. This will normally be shown by an indicator light on the generator. 

Unfortunately if you don’t have this feature, you will need to ensure that you keep a better eye on the amount of oil in the generator to avoid an accident. It can also mean that wear and tear on the parts of the generator is more likely, and the engine can just stop working.

You may not find exhaust control on many devices, but it’s a pretty important factor to consider. Some portable generators can release poisonous fumes into the air that can kill people. Some things make this less likely to happen, such as an automatic shut off when the exhaust pipe has blocked up it useful. Not all generators have this feature.

You should also look out for generators that have heat shielding. This is because some generator can get exceptionally hot when they are working, and if you touch the device at this point you could end up getting burned. 

Not to mention that a surface without heat shielding is more likely to contribute to heat loss, making them less efficient overall.

Maintenance Considerations

Many generators are pretty low maintenance, and you may not need to worry too much if you don’t use your generator very often. 

On the other hand, if you plan on using the generator a lot then you should look for features that make maintaining your device much easier. For instance, things such as wrench sets, motor oil level indicators and screws that can be removed easily are especially useful.

Above all else you should be looking for a motor oil level indicator because this helps you to keep an eye on the oil level regularly. This is the most common type of maintenance that you’ll have to do with a generator.

Not all generators come with wrench sets, and this can make it tricky to get inside of the generator and do any maintenance. This may not be that important if you already have some hex wrenches at your disposal.

Parallel Capability

Not all generators on their own can give you the power you need to get your electrical goods working. In this case, getting a generator that has parallel capabilities is handy. 

This will allow you to hook two generators up together in parallel function, meaning that you’ll have 6000 watts of power available to you rather than 6000 watts. 

This is ideal if you intend to upgrade your electronics later on or if you have higher power needs later down the line. Not all generators offer this functionality, however.
