How to Choose the Best 3000-Watt Portable Generator
The very first thing you should consider when choosing a portable generator is the device’s power. Is a 3000-watt generator enough to cover your power requirements? Check its starting and running watts.
The starting watts rating is crucial especially if the load will consist of several devices that draw a high amount of surge power when starting.
The running wattage is equally important too and should be able to sustain the wattage requirement of the appliances that you’d want to run together.
In addition to meeting your power requirements, check out the generator’s runtime. Regardless of what you plan to use your 3k watt inverter generator for, a longer runtime means that you won’t need to refuel often.
Lastly, consider a 3000-watt generator that offers the most convenient features within your budget. Here, consider the type and number of outlets available, type of starter, available circuit breakers, and gas and oil drain. In addition, check out the type of alerts that the control panel is endowed with, for instance, low oil and remaining runtime.

The Champion 75531i generator will supply you with 3100 starting watts and 2800 running watts of clean power with its EPA and CARB-compliant 171 cc OHV engine. This engine runs for up to 8 hours at 25% load and it’s quiet at 58 dBA.
As you can possibly judge from these wattages, this is a great generator for campers, RV’ers, and tailgaters. It can also be used for low power loads at home and at construction sites.
However, it’s worth noting that unlike most generators in these reviews, the Champion 75531i is not parallel-capable. This is its major drawback that, by the way.
The control panel is nicely arranged and features 2 120v 20A household outlets, 120v 30A RV outlet, and a 12v DC outlet with 2 USB ports.
A unique feature that gives this generator an edge over the others is its trio starting options. You can choose to pull the recoil starter, press an electric starter, or simply use a wireless key fob that works at up to 80ft away.

|Run Time||5 hrs|
|Dimensions (in)||2.4 x 13.2 x 23.5|
If your budget allows you to spend a few hundred dollars on top of what the Wen 56310i costs, the Briggs and Stratton 30545 P3000 might be the best 3000-watt inverter generator for the money.
This generator runs on a 171 cc engine that is capable of delivering 2600 running watts and 3000 starting watts. You’ll find this power output enough for most of your household items especially if you’ll be running them intermittently. You can also run several low-power appliances simultaneously at home, camps, tailgate parties, RV camps, and even on your boat.
The Briggs and Stratton 30545 is fitted with a 1.5-gallon tank and promises a runtime of up to 10 hours at 25% load and 5 hours at ½ load.
This inverter generators control panel is one of its key selling highlights. It features four 120v household outlets, one 12v 5A DC outlet for recharging batteries, and 1 USB port. It also has 1 parallel port should you want to connect 2 generators.
What I find so impressive here, however, is its intuitive Statstation LCD screen that displays vital stats such as runtime and power consumption.
The 30545 P3000 weighs 96 pounds but it’s, all in all, portable thanks to its retractable handle and 6-inch wheels. And Yes- this thing is quiet at 59 dB!

What Can You Run on a 3000-watt Generator?
You can run any appliance on these generators provided the starting power and running power don’t exceed 3000-watts. For instance, for a quick breakfast fix, you could plug in the juicer or a coffee maker as you fry some eggs and later on plug in the dishwasher when nothing else needs powering.
It’s also possible to run several items and run them simultaneously. What’s important is to ensure that the total load is below 3000-watts. That’s to say that you can plug in 2 1500-watt appliances or up to 10 300-watt devices.
When adding a motor-powered appliance to an existing load, ensure that the available wattage capacity is enough for the motor’s starting power demand. For instance, if a generator is running 4 devices with a total running power of 2000 watts, you only have 1000 watts remaining. This means that you might not be able to add another appliance with, let’s say, 1500 starting watts even if the actual running power is 900w.
Here is a list of appliances that you can run on a 3000-watt generator:
|Item||Starting Power (w)||Running Power (w)|
|10,000 BTU AC||2200||1500|
|3/4HP Furnace Fan||2350||875|
|7 ¼’’ Circular Saw||3000||1500|
|Water well pump||–||1000|
There are some good reasons to choose an inverter generator. A 3000-watt portable inverter generator might be a great pick if you want power without compromising the portability aspect of the generator so much.
These generators are capable of running most household appliances (simultaneously or intermittently depending on starting and running power) and can also be used in construction sites as the table above affirms. They are also not so loud and most of them can be used in campgrounds and RVs, as you can find in our article about the best portable generators for RVs.
If you haven’t yet decided on the best 3000-watt generator to buy, the Generac GP3000i is worth checking out. Besides coming from a reputable brand, this generator is easy to start, easy to carry, and remains very quiet even on maximum load.
