Overview

Power outages are no fun. They can put your safety and comfort at risk. That’s why backup power has become a smart investment for homeowners and businesses. Once you’ve decided to get a generator, you’ll quickly face a big question: Should you go with a standby or portable model?

In this blog, Dion Generator Solutions will break down the key differences between the two, from convenience and output to setup and maintenance. By the end, you’ll better understand which type makes the most sense for your power needs and lifestyle.

Highlights

Introduction

The power goes out. Your lights are off, the fridge stops humming, and suddenly, you realize how much you rely on electricity every single day. If you’ve ever been in this situation, you’ve probably considered getting a generator.

But which kind should you choose—standby or portable?

Each option has its strengths, and the right choice is influenced by how much power you want, how often you lose electricity, and how hands-on you’re willing to be. The good news is Dion Generator Solutions is here to help you explore the pros and cons of both so you can choose the best fit for your home or business.

What Is a Standby Generator?

Standby generators are permanently mounted units positioned outside your home or commercial building. They’re hardwired into your electrical system and turn on automatically when the power goes out. These generators run on a continuous supply of natural gas or propane and, depending on the model, can power specific circuits or your entire building.

How It Works

Standby generators include an automatic transfer switch (ATS). This switch monitors your utility power and immediately activates the generator when it senses an outage. Once grid power returns, the system switches back automatically and shuts down the generator.

Standby Generator Features

  • Automatic startup during outages
  • Hands-free operation
  • Powered by natural gas or propane
  • Powers all or part of your home or business
  • Requires professional installation
  • Performs automatic self-tests for readiness

What Is a Portable Generator?

A portable generator is a mobile, fuel-powered unit designed for short-term power supply. It requires manual setup and must be placed outdoors at a safe distance from your building. These generators are best used to power essential items like refrigerators, lights, or other appliances.

How It Works

Portable generators are manually started—either by a pull cord or electric starter—and fueled with gasoline or propane. You can plug appliances directly into the generator or connect the generator to your electrical panel using a manual transfer switch.

Portable Generator Features

  • Manual operation and fueling
  • Typically runs on gasoline or propane
  • Can power a limited number of appliances
  • More affordable upfront
  • Easy to move and store
  • Best for temporary or occasional use

Generator Power Output

Let’s look at how much power the two options provide:

Standby Generator Power Output

Standby generators come in multiple size options to suit different power demands and can power anything from a few vital circuits to an entire house or commercial building. Larger models can handle HVAC systems, kitchen appliances, sump pumps, and electronics simultaneously.

Portable Generator Power Output

Portable generators offer less overall output and are intended to power only the most important items. You’ll typically be limited to just the essentials unless you invest in a higher-capacity model.

Helpful Advice: Make a list of what you need to keep running during an outage and check the wattage requirements. This will help you determine the size and type of generator you should consider.

Convenience and Ease of Use

Ease of use considerations include the following:

Standby Generators

If convenience is your top priority, standby generators are hard to beat. They operate without any action on your part once they’re installed. You won’t need to go outside, refuel, or run extension cords. Everything switches over automatically and keeps running until utility power is restored.

Portable Generators

Portable units require hands-on setup every time you use them. You’ll need to wheel the generator into place, fuel it, start it up, and connect everything manually. It’s not difficult, but it does require time and effort—especially during severe weather.

Generator Installation and Maintenance

Here’s how difficult the two choices are when it comes to installation and maintenance:

Standby Generator Setup

Installing a standby generator is a job for licensed professionals. The process typically includes connecting the unit to your natural gas or propane system, installing an automatic transfer switch, and wiring it into your electrical panel. Local permits and inspections are often required.

These generators are built for longevity and usually perform automatic self-checks. However, they still need occasional oil changes, filter replacements, and professional inspections to stay in top shape.

Portable Generator Setup

Portable generators don’t require installation, but for safer and more efficient operation, many property owners connect them to their electrical system using a manual transfer switch. Others rely on heavy-duty extension cords instead.

Because they’re used less frequently, portable generators should be tested and maintained regularly—especially before storm season. This includes checking oil levels, inspecting fuel lines, and running the generator to ensure everything works as it should.

The Short and Long-Term Costs of Generators

Initial cost isn’t the only factor. Here are the cost factors for these generators in the short and long term.

Standby Generators

While standby generators involve a larger initial investment and require professional installation, they offer long-term value. They provide automatic, uninterrupted power and are built for years of use. Many generator users also find that a standby system can increase property value.

Portable Generators

Portable generators are more affordable at the outset and offer flexibility—you can take them camping, use them on job sites, or move them between properties. However, they have a shorter lifespan than standby models and require more frequent hands-on upkeep. which generator is the safest

Generator Safety Considerations

You’ll want to make sure you pay attention to generator safety:

Standby Generators

Professionally installed standby generators are generally very safe. They’re placed at the proper distance from your home or commercial building, connected to sealed fuel lines, and often monitored with built-in safety features. You won’t need to handle fuel or worry about emissions entering the property.

Portable Generators

Portable models require more caution. If not used correctly, they can present serious dangers, including:

  • Carbon monoxide poisoning from improper placement
  • Fire hazards from spilled fuel or faulty cords
  • Backfeeding, which can endanger utility workers

To use a portable generator safely:

  • Always run it outdoors, at least 20 feet from doors or windows
  • Keep it dry and away from flammable surfaces
  • Use heavy-duty extension cords rated for generator use
  • Install a CO detector in your building for added safety

Practical Applications for Generators

Which generator is best for which situations? Let’s take a look:

Standby Generators Are Best For

  • Properties in areas with frequent or extended power outages
  • Buildings that rely on medical equipment or remote work
  • People who want a hands-off, fully automated backup system
  • Powering an entire building or most major appliances
  • Long-term backup solutions and increased property value

Portable Generators Are Best For

  • Occasional backup during shorter outages
  • Property owners on a tighter budget
  • Individuals who don’t mind manual setup
  • Powering just the essentials (like a fridge, lights, or sump pump)
  • Temporary power needs for camping, job sites, or RVs

Generator Fuel Options

Standby generators typically run on natural gas or propane, both of which are cleaner-burning options than gasoline. They don’t require manual refueling and are less likely to run into supply issues during storms, especially if connected to a utility gas line.

Portable generators can run on different fuel sources. Gasoline-powered models release more emissions and must be refueled regularly, so you’ll need to store fuel in advance. Propane-powered or dual-fuel models offer a more eco-friendly alternative and more flexible fueling options.

Standby vs. Portable Generator Summary

Standby generators offer the ultimate convenience with automatic startup, hands-free operation, and the ability to power your whole home or selected circuits. Since they’re professionally installed and connected to your natural gas or propane supply, they don’t require manual refueling and are generally safer to operate. They also tend to last longer and require less frequent maintenance. However, they do come with a higher upfront investment and must be installed by a licensed technician.

Portable generators, on the other hand, are more affordable and flexible. They’re ideal for powering essential items during short-term outages and can be used for other purposes like camping or on job sites. Since they don’t require installation, you can store them away when not in use and move them easily. The trade-off is that they require manual setup, regular refueling, and more frequent maintenance. They also pose more safety risks, such as carbon monoxide exposure or fire hazards, if not used correctly.

In short, standby generators are great for those seeking a permanent, low-maintenance solution that kicks in automatically. In contrast, portable generators are best for occasional use and budget-conscious buyers who value portability and don’t mind being more hands-on.
