In a Hurry?
No problem. Get started immediately with our top pick directly below.
OUR TOP PICK
The life of the party at our top position here is one of the most handsome generators we’ve ever seen.
It looks like something that fell to earth from an alien spacecraft, harboring technology far superior to our own.
It has a 3500-watt startup, then settles into a cool 3000 running wattage, and it will run for 18 hours on a 25% load.
It should be able to power microwaves, laptops, washing machines, hairdryers, lights, all the essentials.
As is the case with pretty much all inverter generators, the Generac has a full enclosure that serves three purposes.
One, it protects the complex and expensive inner workings of the generator. Two, it brings the volume down to a purring 55dBA.
That’s just slightly louder than the average computer, or if you want to get poetic about it, about twice the volume of leaves rustling in the wind.
Three, it allows designers to be more adventurous with aesthetics and color.
But the beauty of this machine is far from cosmetic.
It’s called the iQ for a reason. Pushing the power rush button on the panel gives you a 50% starting capacity boost, making it capable of powering extremely demanding appliances.
You can also use two in parallel for epic powering potential, taper the power consumption with the economy switch, and observe the seamless functionality via the smart digital LCD display.
- Can run in parallel with other iQs
- 3500-watt startup and 3000-watt running power
- Digital LCD display keeps you in the know
- Looks amazing
- Highly portable
- Steel enclosure keeps makes it incredibly sturdy
- Gentle volume
- Power rush will power demanding electronics
- Runs up to 18 hours on a quarter load
- Pretty expensive
- 109lbs is on the heavy side of portable
Bringing some of that industry-leading technology to our second spot here is a Honda generator with a 3000-watt startup and a 2800 watt running rate.
It may not be quite as powerful as our top pick, but for fuel efficiency, it can’t be beaten.
You’ll get around 20 hours of constant power from the EU3000 on a minimum load and up to 7.2 if you’re pushing its limits.
That’s 2 hours longer than the iQ with the same sized 3.4-gallon tank.
It achieves this via the eco throttle technology that reduces power consumption to a minimum.
That said, the Honda is a fraction louder and way heavier than our top pick.
It runs at a max volume of 58 decibels, 3 more than the Generac, but let’s be honest, you’re not going to pick up on that in any big way.
It weighs in at 131lbs which is roughly the same as a small adult, so it’ll definitely take its toll carrying this by hand.
The full enclosure is really well designed and solid as a tank, making this ideal for rugged environments and workplaces.
It can also function in parallel just like the iQ, giving you stackable energy sources for demanding applications.
The elephant in the well-lit room here is the price.
The EU3000 costs roughly more than three times the price of the iQ despite their similar functionality.
That said, Honda are one of the leading manufacturers of engines in the world. What that’s worth is up to you.
- Honda are renowned for their motors
- Solid enclosure keeps it safe for rugged use
- More efficient than the iQ
- Automatic low oil shutdown
- Quite running
- Can be used in parallel
- Well designed handles
- Striking red and grey finish
- Exceedingly pricey for a small generator
- Pretty heavy for a portable device
With 3060 running watts, this isn’t strictly a 3000-watt generator, but it’s so much better than some of the 3K options out there, we thought we’d include it anyway.
It’s cheaper than most inverters too.
One of the best things about this Champion unit is the dual fuel running option.
This means you can use either gas or propane to strike this thing into life.
Dual running options ultimately make for a more reliable generator.
You can use your gas for day to day running and keep a store of propane for emergencies as it doesn’t expire.
The 1.6-gallon gas tank should provide you 7.5 hours of clean power, while hooking up a 20lbs propane tank will give you 14.5 hours of constant power.
If that’s not enough for you, set it to economy mode and witness it go even longer.
Considering this generator has a similar power rating as our number one pick, Champion have done an amazing job at keeping the design really practical and portable.
It comes with sturdy wheels for easy transportation and it weighs less than 100lbs.
At 59dBA it’s slightly noisier than our top picks, but due to its extra power, you’re likely going to be running this on a smaller load, meaning the motor will run quieter.
Everything about this generator is well thought out and designed to make life easier.
It can run in parallel, it’s lightweight, and an electric start function will have it running at the flick of a switch, supplying instant power where it’s needed.
- Most powerful running wattage on our list
- Parallel potential
- Quiet running
- Dual fuel design
- Sturdy wheels make moving this thing a breeze
- Lightweight construction
- Intuitive control panel
- Great price for a generator of this power
- Economy mode saves fuel and prolongs run time
- Electric start saves time and effort
- Not technically a 3000-watt generator
- Quite a small gas tank
Our fourth product is a generator that leans more into portability than capacity but still provides you with an insane ¼ load 10 hour run on a single 1.5-gallon tank.
Pretty impressive, really.
This little illuminator runs at a very bearable 58 - 59dBA.
You probably wouldn’t notice the difference between this and our top two unless you lined them up next to each other and listened very carefully.
Where the P3000 really shines in comparison to our top picks is the four household outlets.
Both the iQ and the EU only feature two, so although this is a weaker device, it may provide more usable energy overall.
A full tank won’t last too long if all four ports are in use, but it’s still a great design.
We think the best thing about this generator is its true portability.
It weighs less than 100lbs, has great static handles, sturdy 6-inch wheels (the first on our list), and an extendable, telescopic luggage style handle.
The P3000 is 3000 starting watts and 2600 running watts, pretty impressive for its size, and if you need more power, it can twin up in parallel like our top picks.
It’s a solid build, but the fuel input is right above the outlets, so you have to be extra careful when refueling.
- 6-inch wheels
- Solid build with static handles
- Telescopic handle for easy transportation
- 3000-watt startup
- Can be used in parallel
- 4 household outlets
- Really quiet running volume
- Should run for 10 hours on ¼ load
- Probably not quite powerful enough to power AC in RVs
- Lower running watts
- Fuel tank opening is directly above outlets
- Quite expensive for a smaller generator
You can consider this generator the iQs little sibling.
With a 3000 watt startup and 2300 running wattage, it’s the perfect little generator for smaller applications like hairdryers, TVs, phone chargers, fans, toasters, and laptops.
It runs short for a microwave though.
At 59.5lbs, this is the lightest generator on our list so far, ideal for loading and unloading during travel.
It would be better if it had wheels like the P3000, but the large, central handle makes for a solid, ergonomic grip.
The GP3000i has the same smart power rush option as its larger kin, providing a 50% startup boost for demanding applications.
If you appreciate efficiency when you’re only using a few appliances, the economy switch has you covered.
It’s designed to be a super quiet running generator but we had trouble finding an exact running volume.
We’d assume it’s similar to the iQ, less maybe, due to its smaller size.
While you don’t get the fancy LCD digital statistic screen, important information is displayed clearly using labeled LED lights in the top right-hand corner of the panel.
The leftmost green light is the power indicator, the middle is a red overload warning, and the right hand warns you of low oil.
- Economy switch for making the most of your fuel
- Can run in parallel
- Easy to understand warning system
- Quiet running
- Very lightweight
- Power rush function boosts startup power
- Sturdy build and ergonomic handle
- Well priced
- Not as powerful as other picks
- Would be better if it had wheels
Generators are one of the most confusing items you can shop for if - like most people - you’re not sure how they or the industry works, but don’t worry.
We’re going to discuss some of the things you may want to consider before settling on a 3000-watt inverter generator.
What is an Inverter Generator?
Let’s start by going over what an inverter generator actually is to make sure it’s what you're looking for.
Put simply, an inverter generator is capable of producing a pure sine wave with the perfect amplitude and frequency, allowing them to power sensitive electronics without any adapters.
They’re built using state of the art technology to make them safer, more practical, and more efficient than their traditional counterparts. Sound good?
There are some downsides to consider. You’re going to have to fork out quite a bit more cash for an inverter generator than for a standard model of the same size.
It’s always good to come up with a rough budget, but as we said, inverter generators can carry some steep price tags.
Starting Watts and Running Watts
Starting watts are the initial surge of power a generator supplies to launch electronics. Running wattage is the power level a generator will provide at a constant rate.
For example, a hairdryer may require 1600 watts to initially power, but once it’s on, the demand will fall to a consistent 1000 watts.
Your Power Needs
Finding out your power requirements should always be the first step in shopping for a generator.
Obviously, you’re in the market for a 3000-watt unit, but is that starting watts or running watts?
You should be able to find out the starting and running requirements of an appliance somewhere on its enclosure, packaging, or from the manufacturer.
Simply add up the running requirements of all the things you want to power and you’ll know exactly what you require from a generator.
Most 3000-watt inverter generators will have at least two household outlets, a DC outlet, and a larger outlet for more intensive applications like supplying power to an RV.
There are different outlet variations available on the market, so if there’s a format you’d prefer, it may be out there.
Portability is another great thing about inverter generators but some are more practical than others.
If you want to make transporting your generator as easy as possible, look out for designs with wheels.
This will save you from lifting the whole unit every time it needs moving
It’s also a great idea to compare their weights. A 3000-watt generator could weigh anywhere between 50 and 140lbs.
For stress-free transportation, we recommend choosing a generator that weighs less than 100lbs.
A sturdy and ergonomic handle(s) is essential, especially on heavier models.
You should check the number, location, and shape of handles on a generator before purchase. You may even luck out with a luggage style telescopic handle similar to our fourth pick.
This isn’t the be all and end all deciding factor in running time, but generally speaking, the larger the tank, the longer your generator will run.
If your intended applications aren’t that demanding, a 1.5-gallon tank will be enough for lengthy usage.
If you have more intensive applications in mind, we recommend looking at something more along the lines of 3 gallons or above.
The main thing to be aware of here is that running time is often measured in hours under a specified load.
This won’t be the running time if you’re pushing the generator to its limits. For example, a 10 hour running duration on a 25% load means that one tank will last 10 hours when the generator is running at ¼ its capacity.
That adds up to a 2.5 hour running time when pushed to its limits.
One of the best things about inverter generators is their extra quiet performance. Most 3000 watt models will have a lovely running volume between 55 and 60dBA.
It’s not a massive range, but the human ear can detect 1dBA increments in volume, so if volume is important to you, it makes sense to get the quietest generator possible.
Inverter generators are incredibly expensive products with loads of complex state of the art internal mechanisms that need reliable and rugged protection, especially if they’re used in rigorous commercial environments.
Luckily, they’re fully enclosed designs, but some enclosures will be more heavy-duty than others. You can gain an understanding of the build quality of an enclosure by learning about the materials used and reading up on customer reviews.
Frequently Asked Questions
Can a 3000-watt generator run a house?
No, 3000 watts isn’t enough to power the average household, but it will provide you with enough power for all the essentials.
Is an inverter generator better than a regular generator?
In many ways, yes. They’re quieter, safer, more fuel-efficient, offer greater user control, and provide a pure sine wave for powering sensitive electronics.
That said, they’re more expensive and often smaller than their counterparts. If raw power is more important to you, a standard generator may be more appropriate.
Can you use inverter generators indoors?
No, never use a gas or propane generator indoors, especially if there’s low ventilation.
Carbon Monoxide poisoning can kill. A portable battery power station is more suited to work indoors.
