Best 5,000 Watt Generator Buying Guide

So, now you’ve seen the benefits of the 5 different 5,000-watt generators we’ve reviewed, but you might still be wondering how to choose the best option for your energy needs.

That’s where our handy buyer’s guide comes in, as we’ve put together some information to point you in the right direction. But first, what can you actually run on a 5,000-watt generator? Keep reading to find out...

Uses for a 5,000-Watt Generator

Generators are a great investment because of the backup power they can provide in the case of an emergency.

With 5,000 watts, you can run a few small appliances at once, but trying to power too many things at the same time is not recommended as you may end up overloading the engine which can cause damage to the unit. 

If your power cuts out, one of the first things you’ll want to think about is keeping your fridge and freezer running so your food stays fresh. As long as these appliances are below the 5,000-watt maximum output, it’s perfectly safe to power them using your generator. 

Smaller electronic devices can be powered or charged too, as can your light fixtures and any other small-medium machines found in your home. But its capabilities are not just limited to household appliances!

If you’re left without power on site you can use your generator to run your drills, power saws, grinders, and other power tools that operate on less than 5,000 watts.

The best thing you can do is make a list of the appliances you wouldn’t be able to live without if you end up in a power outage, and add up their collective ‘starting’ and ‘running’ watts to get an accurate idea of what appliances you’ll be able to run. 

What Are Starting and Running Watts?

Look, you’re not the first person to ask, but starting and running watts are important things to know about when it comes to generators. If you confuse the two, you run the risk of accidentally overloading your unit and potentially causing irreparable damage.

  • Starting watts refers to the initial surge of power your generator can deliver, hence why it’s also commonly known as ‘surge’ watts. 
  • Running watts is the amount of continuous power your generator can supply for a sustained period of time. You might also see ‘rated’ watts in the product specifications, but this is the same thing.

Appliances will also state what their starting and running watts are, which is especially important to consider when you’re adding up the total wattage of certain appliances so you can ensure that you stick to the 5,000 watt limit. 

Noise Levels

Decibels are a unit of measurement that refers to how loud something is. Is it just us, or is this beginning to feel like a high school science lesson? Don’t worry, it’s not actually that complicated. The basic principle is as follows: the higher the decibel rating, the louder the noise produced while your generator is operating. 

If you’re planning on using your generator for home use, you might want to choose a generator that is quieter when it’s running, whereas construction sites tend to be noisy areas anyway therefore the decibel rating won’t necessarily have much influence in your decision. 

Unless otherwise stated in the product description, you should assume the provided decibel number applies to when the generator is running at full load. Some will include specs for half load, which is also good to know.

Size and Portability

A 5,000-watt generator is obviously going to be bigger than a one with less power output, but it’s nowhere near the size of some of the larger generators that are upwards of 10,000 watts! These are the real bad boys of the generator world. 

The size of the generator is good to know because storage space will likely play a part in your decision, and if you’re planning on using your generator for work where you may have to move from site to site, you’ll also want to consider size in terms of portability and how easy it is to transport. 

Most quality generators will have wheels or handles on the unit, and to be completely honest, you’d have a hard time moving your generator around without them. The weight of a 5,000-watt generator can range from 109 lbs to upwards of 150 lbs, so imagine trying to drag that into position...

Other Features

When it comes to generators, you should be looking for features that are going to make the unit more convenient for its intended use as well as protecting the engine. 

There are some basic essentials that the majority of quality generators will have, as well as more advanced functions for you to choose from. Ultimately it will come down to what features you would find personally useful. 

The features we consider to be most important are things such as an indicator that tells you when your oil is running low and an automatic shut off function that protects your engine, digital displays that allow you to monitor the generator’s output, and alternators that work to stabilize the power being delivered to your devices. 

Best 5,000 Watt Generator - Frequently Asked Questions

Can a 5,000-watt generator run a house?

It can certainly be used to run a number of the most critical appliances in your home, but a 5,000-watt generator cannot run an entire household. You’d need to be looking at generators that are in excess of 7,500 watts to run these all at once or for extended periods of time.

How many appliances can you run at once on a 5,000-watt generator?

As we’ve stated previously in this article, the only way to answer this question accurately would be the total the watts of each appliance you’d be using and see which combinations add up to less than 5,000 watts. 

How can I make my generator quieter?

If you needed to prioritize other factors in the decision of which generator to purchase, and now you’ve ended up with one that’s just too loud to ignore, don’t panic! One simple solution to reduce the noise your generator makes when it’s running is by using a muffler.
