What Do You Need To Know Before Buying a Home Generator?
Before buying a home generator, consider how the unit’s design and specifications affect performance. It’s important to evaluate several factors, like generator type, wattage, power source, and noise level, to find the model that best fits your home and lifestyle.
Home Generator Types
Home generators come in a variety of models, including standby generators, portable generators, inverter generators, and portable power stations.
- Standby generators: These generators connect directly to your home’s electrical panel and automatically turn on during a power outage. Most models run on natural gas, which is convenient but requires professional installation.
- Portable generators: Thanks to a compact design, users can more easily move these models around the house or job site. While portable generators can run essential appliances, they typically don’t have enough power to support an entire home.
- Inverter generators: This type of generator automatically adjusts its engine speed to match power demand.This results in better fuel efficiency and a lower operational noise. They also deliver “clean” power that’s safer for sensitive electronics like laptops and TVs.
- Portable power stations: These generators use battery power instead of fuel. They’re ideal for small electronics and short-term power needs.
Pro Tip
- When running a dual-fuel portable generator like the DuroMax during an outage, avoid powering high-draw appliances all at once. As one This Old House segment demonstrated, the best approach is to “turn everything off, turn the generator on, make your switch… now start turning things back on one at a time.” Prioritize essentials like your well pump, furnace, and refrigerator—but keep away from electric ovens, dryers, and central air conditioning, which can overload the unit and cause it to shut down.
Wattage
Wattage refers to the amount of power a generator can deliver. Most models list two values: starting watts, which are required to turn on an appliance, and running watts, which are needed to keep units operating. Running wattage typically ranges from 1,000W–10,000W. The higher the wattage, the more appliances a generator can handle or the larger the individual appliances it can power.
For example, a 7,500W generator can power essentials like your fridge, sump pump, and lights during an outage. Smaller models, around 1,000W, can handle basic electronics like phones and tablets.
Fuel and Power Sources
Generators can run on one or more fuel types:
- Gasoline: This is the most common and widely available generator fuel. It’s typically the most affordable option, but it’s also highly flammable and more difficult to store for long periods.
- Diesel: Diesel is more fuel-efficient than gasoline and has a longer shelf life. However, diesel-powered generators are less common and tend to be louder during operation.
- Propane: Propane burns cleaner than gasoline and is easier to store, making it a popular choice for home use. However, it usually delivers slightly less power output.
- Natural gas: Used exclusively in standby generators, natural gas provides a constant supply from utility lines and eliminates the need for fuel storage. However, it’s less energy-dense and not compatible with portable models.
- Solar: Ideal for portable power stations, solar energy is a clean, renewable energy source. However, solar generators typically have slower charging times and lower overall power output than fuel-based alternatives.
Some models support dual-fuel or even tri-fuel capabilities, meaning they can run on multiple fuel types. These generators offer greater flexibility during emergencies when owners may only have access to a single fuel source.
Generator Noise Levels
Generator noise varies based on type, power output, and build quality. Inverter generators and enclosed portable models are generally quieter, often operating between 48 and 60 dBa, which is about the sound of a normal conversation. Conventional portable and standby generators are louder, usually ranging between 70 and 90 dBa.
High-End and Smart Generator Features
Modern home generators often include convenience and safety upgrades that enhance usability and overall functionality.
- Carbon monoxide (CO) sensors: Automatically shut off the generator if the unit detects dangerous CO levels.
- Electric or remote start: Starts the generator at the push of a button or via a key fob or smartphone app.
- Fuel gauges and run-time meters: Help users track fuel use and service needs.
- Mobile apps or Bluetooth connectivity: Allows remote monitoring of generator output, fuel levels, runtime, and maintenance alerts.
- Transfer switch compatibility: Makes it safer and easier to switch between generator and grid power.
Pro Tip
- No matter how convenient a portable generator is, carbon monoxide safety is critical. As highlighted in a This Old House segment, “do not run it in the garage, do not run it in the house, make sure it’s on the outside of the building.” Look for models with a built-in CO sensor that will automatically shut the unit down if dangerous levels are detected—a feature that’s increasingly standard on quality portable generators.
How To Use a Home Generator Safely
Using a generator can become dangerous if you don’t take the proper precautions. Here’s a list of some essential safety tips:
- Operate your generator outdoors: Always run gas-powered generators at least 20 feet away from your home. Never operate these units inside garages, sheds, or other enclosed spaces, as this can lead to deadly carbon monoxide buildup.
- Install a transfer switch: A transfer switch allows you to safely switch between utility power and generator power without backfeeding electricity into the grid. This reduces the risk of electrocution and appliance damage. If you’re unsure how to install one, hire a licensed electrician.
- Keep your generator away from flammable materials: Maintain at least five feet of clearance around the generator to prevent nearby surfaces from overheating and catching fire.
- Use a fuel stabilizer for storage: If you’re storing gasoline for extended periods, add a stabilizer to prevent degradation and reduce the risk of fire.
- Refuel only when the generator is cool: Let your generator cool down before adding fuel. Never refuel near open flames, heaters, or other heat sources.
- Test your generator before an emergency: We recommend running your generator when you first receive it and periodically thereafter to ensure it works properly and that you know how to operate it.

FAQs About Home Backup Generators
What type of home generator do I need?
The right home generator depends on what you need to power. For small electronics and light appliances like coffee makers or TVs, a portable power station or inverter generator may work best. For larger appliances or whole-home coverage, consider a standby generator or a high-wattage portable generator.
How much does a home generator cost?
Home generators can range widely in price based on size, features, and fuel type. In our research, we found that most portable generators cost between $500 and $1,500, while standby generators can cost $2,000–$6,000 or more, including installation.
How do portable generators create power?
Portable generators convert fuel, typically gasoline, propane, or diesel, into mechanical energy, which spins an alternator to generate electricity. This electricity is then delivered through outlets on the generator for household or emergency use.
How long can a generator run continuously?
Many portable generators can run for eight to 14 hours at 50% load on a full tank of gas. Standby generators connected to natural gas can often run indefinitely, provided users perform maintenance and oil changes regularly.
How often should I maintain my generator?
Check the oil level before each use and change the oil every 50–100 hours of operation, or as recommended by the manufacturer. Also, regularly inspect air filters, spark plugs, and fuel stabilizer levels—especially before storm season.
