To help you in your search for the best 5000 watt generator, we’ve reviewed the top 5 models on the market.

Let’s dive in and see which of them fits best to your needs.

How to Choose the Best 5000 Watt Portable Generator

Our first piece of advice for anyone buying a portable generator for the first time is to establish a budget that they intend to work with. 5000 watt generators come at all prices. Targeting a certain price range is a surefire way to narrow down your options while getting the best bang for your bucks.

Next, consider the power needs of all the power appliances that you can’t afford to go without when the grid is down. Here, you might want to make a list of these items and then add their starting and running watts to ensure that the generator meets the power requirement. In this article, we provide some examples on what you can run on a 5000 watt generator.

The next step would be to determine generator’s running time at half load as well as the size of the tank. Generally, the longer a generator can run on a full tank, the less often you’ll need to refuel it.

Lastly, and more importantly, pay attention to its features. Among other basic features that we consider paramount on a 5k watt generator’s control panel include a main circuit breaker, low-oil indicator and shutoff, electric starter, and a fuel gauge.

Pulsar isn’t a household name yet. But there’s no doubting that this Canadian company is one of the fastest growing names in the world of generators.

Their PG6000 made it to our list of the best 5000 watt generators for 2 main reasons: its high starting watts and unbeatable runtime.

This generator uses a 302cc 10 HP engine that outputs a peak power of 6000 watts and a running wattage of 5000 watts.

A portable generator with this enormous starting power is what you need for a construction site or a workshop where you constantly need to start other tools without powering off the current one. And it gets much better with its long runtime.

The PG6000 can run at half its capable load for up to 15 hours with its 6.6-gal tank full. That’s to say that it can manage around 20 hours at quarter load if you intend to power, let’s say, a freezer and some security lights at home.

Its control panel has a total of 7 outlets and can accommodate 120v, 240v, and 12v operations. You’ll find four 120v AC receptacles, one 120/240v Twist-Lock outlet, one 120v Twist-Lock outlet, and a 12v DC outlet.

This already impressive generator is made complete by a low-oil indicator, a 3-in-1 digital meter, and an Automatic Voltage Regulation.

Noise Level 74 dBA
Tank size (gal) 6.7
Run Time 10 hrs
Dimensions (in) 28.8 x 26.8 x 25

Generac 5939 is a very powerful generator, especially for a construction site. Reason? This generator uses a 389cc OHV engine with peak power performance of 6,875 watts and a running power of 5,500 watts. Notably, this engine uses a splash lubrication system that guarantees it a long life with minimal maintenance needs.

The Generac 5939 has a 6.7-gallon tank from which it can output 50% of its total wattage power for up to 10 minutes. This isn’t the best runtime compared to other generators in these reviews. But it’s still acceptable considering its power output and the price that this generator comes at.

The control panel is one of its best fronts. It has a digital display with the number of hours to the next maintenance and a circuit breaker. Its four 120v outlets one 120v/240v receptacle have also been covered for protection against spills.

What can you run on a 5000 watt generator?

The type of appliances that a 5000 watt portable generator can run basically depends on their power consumption (starting watts and running watts).

Depending on its power requirement, one appliance may draw all the power output of the generator thereby making it impossible to plug in another device. Other appliances draw a very little amount of power, therefore, leaving you with more power to plug in several other devices/equipment.

To determine the amount of power that each of your items draws, check its power requirement. This is mostly affixed on its power cord or on its nameplate. Most manufacturers indicate it in watts although there are a few that use amps. To convert amps into wattage, simply multiply the amperage rating of the appliance by the voltage at which it operates (120v or 240v).

Importantly, remember to consider each appliance’s starting watts and running watts. Ensure that your target load falls within the generator’s starting and running watts capability.

Generally, a 5000 watt generator should be able to cover most of the basic household appliances during an outage. It’s also capable of running several power tools at a construction site including electric sprayers, circular saw, and air compressors with a starting wattage of below 5000w.

Here is a list of appliances you can run on a 5000 watt generator:

Household Appliances Starting Watts Running Watts
Coffeemaker 1200w 900w
Clothes dryer 5000w 1800w
Portable heater 1500w 750w
Dishwasher 2400w 1200w
Toaster 1400w 800w
Water heater (40-gal) 5500w 4500w
Water Pump (deep well) 1100w 250w
