The Essential Guide to Buying Your Portable Generator

A portable generator is a powerful tool. It brings electricity when the main power goes out. It also powers tools at remote job sites. Choosing the right one takes a little know-how. This guide helps you pick the best fit for your needs.

Key Features to Look For

Several features make a generator great. Focus on these when you shop:

Power Output (Wattage)

  • Starting Watts: This is the big surge of power needed to start big appliances like refrigerators or air conditioners.
  • Running Watts: This is the steady power the generator produces continuously. Make sure this number covers everything you need to run at once.

Fuel Type

Generators run on different fuels. Each has pros and cons:

  • Gasoline: Most common and easy to find. It stores poorly over long periods.
  • Propane (LPG): Stores almost indefinitely. It often provides less running power than gasoline.
  • Dual-Fuel/Tri-Fuel: These offer flexibility, letting you switch between fuel sources. This is great for emergencies.

Runtime and Fuel Tank Size

Check how long the generator runs on a full tank at a 50% load. A larger tank means less refueling, which is crucial during long outages.

Noise Level (Decibels – dB)

Generators are loud. Look for models under 65 dB if you plan to use it near neighbors or while camping. Inverter generators are usually much quieter than traditional open-frame models.

Portability and Weight

Since it is “portable,” weight matters. Smaller units might have wheels or sturdy handles. Test how easy it is for one person to move.

Important Materials and Build Quality

The materials used directly affect how long your generator lasts and how safe it is.

Engine Quality

A quality engine uses durable metals, like cast iron cylinder sleeves. Good engines last longer and require less maintenance. Look for well-known brand names in the engine world.

Frame and Housing

The frame protects the vital parts. Steel frames offer excellent protection against bumps and weather. A powder-coated finish prevents rust, which is important if you store the unit outside.

Outlets and Connections

Good generators use high-quality outlets that resist corrosion. Ensure they include the proper safety features, like circuit breakers, to prevent electrical overload.

Factors That Improve or Reduce Quality

Quality Boosters

  • Inverter Technology: These produce “cleaner” electricity. This clean power is safe for sensitive electronics like laptops and TVs.
  • Automatic Voltage Regulation (AVR): This keeps the power output steady, protecting your appliances from surges.
  • Electric Start: Pushing a button to start the engine beats pulling a cord every time.

Quality Reducers (Things to Avoid)

  • Cheap Plastic Parts: Plastic components on the housing or fuel cap break easily under stress.
  • No Oil Sensor: A low-oil shutoff feature protects the engine if the oil runs low. If a generator lacks this, you risk destroying the engine quickly.
  • Open Frames: These expose the engine to dirt, rain, and debris, which reduces its lifespan.

User Experience and Use Cases

Think about where and how you will use the generator most often.

Emergency Home Backup

For outages, you need reliable running wattage to keep the fridge and a few lights going. You might need a higher wattage model, often 5,000 watts or more, to handle central air or well pumps. Quiet operation is a major plus here.

Recreational Use (Camping/Tailgating)

Campers need quiet, fuel-efficient inverters. They usually only power small items like lights, fans, and phone chargers. Weight and size are very important for easy transport in an RV or car trunk.

Job Site Power

Construction sites need raw power for large tools like saws and compressors. These users often prioritize ruggedness and high starting wattage over quietness. Dual-fuel options are popular because propane stores better over the long downtime between jobs.


10 Frequently Asked Questions (FAQ) About Portable Generators

Q: What is the difference between a conventional and an inverter generator?

A: Conventional generators make power directly, which can sometimes harm sensitive electronics. Inverter generators make DC power first, then convert it to clean, steady AC power, making them much safer for computers and smart devices.

Q: How much wattage do I need to run a refrigerator?

A: A standard refrigerator usually needs around 600 to 800 running watts, but it needs a surge of about 1,500 to 2,200 starting watts. Always check your appliance’s specific requirements.

Q: Can I run a generator in my garage?

A: Absolutely not. Generators produce deadly carbon monoxide gas. You must always run them outdoors, far away from windows, doors, and vents.

Q: How long can I safely store gasoline for my generator?

A: Untreated gasoline starts to degrade in about 30 days. If you use a fuel stabilizer, you can often extend this storage time to six months or more.

Q: What does “running at 50% load” mean?

A: This is a standard testing measure. It means the generator is operating at half of its maximum rated running wattage. This is how manufacturers calculate the longest runtime per tank.

Q: Are portable generators street-legal for running during a power outage?

A: Yes, they are legal to use, but you must follow local noise ordinances. You cannot run them for days straight if your town has quiet hours, usually at night.

Q: What maintenance do I need to do regularly?

A: You must check the oil level before every use. You should also change the oil after the first 5 to 20 hours of use, and then every 50 to 100 hours after that, depending on the manual.

Q: What is a transfer switch, and do I need one?

A: A transfer switch safely connects your generator to your home’s main electrical panel. It prevents “backfeeding,” which sends power back onto utility lines and can severely hurt utility workers. It is highly recommended for safe home backup.

Q: Why do some generators cost so much more than others with similar wattage?

A: Higher prices usually mean better quality components, like an inverter engine, superior sound dampening, a longer warranty, or the ability to run on multiple fuel types.

Q: Should I buy a generator with a wheel kit?

A: If the generator weighs over 100 pounds, a wheel kit is a huge benefit. Moving a heavy machine by yourself can lead to strains or accidental tipping.
