How to choose a portable generator for a house

Choose a portable generator for a house by matching its fuel-specific running watts and outlet to a written list of the loads you need during an outage. Then check where it can run safely, how you will connect it and how you will keep fuel available.

Start with priorities. A refrigerator, sump pump, well pump, furnace blower, lights, phone charging and a few outlets may matter more than trying to power every appliance at once.

Write down the running watts for each priority item and mark any motor or compressor that needs extra starting power. Add the items you expect to use at the same time, then compare the total with the generator's running rating on your selected fuel.

Starting watts are temporary and apply only when an appliance starts. If multiple motors might start together, plan for the combined starting demand or stagger their use where practical.

The generator's outlet is part of the decision. A transfer-switch-ready 30A or 50A outlet can support a home connection plan, but it must match the transfer equipment and circuits installed by a qualified electrician.

For a deeper load worksheet, use our guide to how many watts a house needs. The guide to starting watts versus running watts explains how to account for brief motor startup demands.

Which generator size suits your backup plan?

A smaller generator suits a short list of essentials, while a higher-output model gives you more room to run several larger loads together. The right size comes from your actual appliances, not the square footage of your house.

A 4500 to 5300 running-watt plan may fit a limited set of essentials if the starting demands stay within capacity. Several picks here fall in that range, with some ratings varying by fuel.

Around 6500 to 7500 running watts gives more headroom for a broader selection of circuits, but it still does not guarantee that every appliance can run at once. The 9500-watt gasoline rating of the top pick is the highest continuous output among these products.

Do not size by peak or starting watts alone. If your plan includes a refrigerator, pump and air conditioner, check each unit's running and starting needs and ask an electrician which circuits can be connected together.

For appliance-specific estimates, see what size generator can run a refrigerator and our guide to what size generator a sump pump needs.

Should you choose gasoline, propane or natural gas?

Choose a fuel based on the generator's available ratings and the fuel you can store or access safely. Dual-fuel and tri-fuel models add options, but their running output can change from one fuel to another.

Gasoline is familiar and all the gasoline ratings in this group are stated, but outage plans must account for safe storage and refueling. Propane can be useful if you already keep suitable cylinders, though its rating is lower than gasoline on the dual-fuel picks.

Natural gas is available on two tri-fuel models here. That option depends on a compatible supply and connection, so have a qualified professional confirm the installation and follow the generator's instructions.

Compare the rating for the fuel you expect to use most often, not just the highest number in the product name. For the tradeoffs in storage and fuel handling, read our propane versus gas generator guide.

Does a 30A or 50A outlet matter for home backup?

The outlet matters because it must match the transfer equipment and connection plan for your home. A larger outlet does not increase the generator's rated wattage.

A 30A connection may fit a selected-circuit setup, while a 50A connection can serve a different planned arrangement. Which is appropriate depends on your panel, generator output, transfer equipment and intended loads.

Have a licensed electrician review the full setup before buying. Never connect a generator to household wiring through a wall outlet, since that can put people and utility workers at risk.

Read our portable generator versus standby generator guide if you are deciding between a movable unit and a permanently installed system. For cord-based connections to individual appliances, use the guide to choosing a generator extension cord.

How should you set up and care for a home generator?

Set up a portable generator before an outage by learning its controls, checking the manual, planning a safe outdoor location and arranging any home connection in advance. A ready plan reduces rushed decisions when power is already out.

On first setup, complete the assembly and maintenance steps in the manual, including adding the specified oil if required. Check the supplied parts, identify the starting method and learn how to read the fuel gauge or operating display before relying on the unit.

Store the generator where it stays dry and accessible, but only operate it outdoors with the manual's required clearances. Keep cords away from walkways and use cords suited to the connected load; have a professional install transfer equipment.

Follow the manual's service intervals for oil, filters and other maintenance. The hour meter on some models can help track use, while fuel shutoff on the WEN inverter helps clear remaining fuel from the carburetor before shutdown.

Fuel storage and shutdown steps differ by model and fuel. Use approved containers and the manufacturer's directions, and keep enough fuel for the outage duration you expect rather than assuming a maximum runtime will hold at every load.

What mistakes should you avoid with a portable generator for house backup?

The most common mistake is buying by peak watts or headline wattage without checking running watts for the chosen fuel. That can leave a generator short of capacity during the outage.

Another mistake is assuming that a transfer-switch-ready outlet means the generator can connect directly to any home's panel. Outlet type, voltage, wiring and transfer equipment all need to match and should be reviewed by an electrician.

Don't place a generator in a garage, basement, porch or other enclosed or partly enclosed area. Keep it outdoors away from openings, and follow the placement distances in its manual even when the unit has a carbon monoxide sensor.

Finally, don't plan around running every appliance at once unless the load calculation supports that use. Decide which loads matter most, identify what can be switched off, and practice a safe sequence for bringing appliances online.

Where should a portable generator sit during an outage?

A portable generator must run outdoors, far from doors, windows and vents, following the placement distances in its manual. Carbon monoxide is odorless and can be deadly, so never operate one inside a home, garage or enclosed area.

Keep the generator dry and protect it from rain only in a way the manufacturer permits. Follow the manual for grounding, fuel handling and operation, and keep exhaust away from openings that could draw it indoors.

See our guide on how far a generator should be from the house before deciding where to store and run it. A CO shutdown feature is an added safeguard, not permission to use a generator indoors.

Which portable generator for a house should you choose?

Choose the Westinghouse 12500W Dual Fuel Home Backup if your load plan needs its high running output and 50A outlet. Pick the Westinghouse 6500W Dual Fuel or WEN 8000W Dual Fuel when a 30A setup and their fuel-specific ratings cover your essential circuits.

Choose the Westinghouse 8200W Tri-Fuel Inverter or Genmax 8000W Tri-Fuel Inverter if three fuel options are central to your plan and their output fits your loads. The WEN 6800W inverter is a lower-output option when inverter design and dual-fuel operation matter more than maximum capacity.

Before buying, compare running watts on your chosen fuel, motor starting needs, connection type and safe placement. Then use our portable generators for home use guide to review the rest of your backup plan.

Frequently asked questions

How many watts does a portable generator need to run a house?

There is no single wattage that runs every house. Add the running watts of the appliances you want at the same time, then account for the highest starting load, such as a pump or motor.

Compare that total with the generator's running watts for the fuel you plan to use.

Starting watts are temporary.

Can a portable generator power a whole house?

A portable generator can power selected home circuits or appliances when its output and connection equipment are suitable. A whole-house plan depends on the home's load, generator capacity and properly installed transfer equipment.

Ask a licensed electrician to assess the connection and circuits before buying.

Is a 30A or 50A generator outlet better for a house?

The right outlet depends on the transfer equipment and loads your electrician plans to connect. A 50A outlet can support a different connection setup than a 30A outlet, but it does not make a generator produce more watts.

Match the outlet, voltage and generator output to the home's approved connection.

Can I run a generator on propane during an outage?

Yes, if the generator is designed for propane and you have the correct connection and enough fuel. Check its propane running-watt rating, since it may be lower than the gasoline rating.

Store and handle fuel according to the generator manual and local requirements.

Where should I place a portable generator?

Run a portable generator outdoors, far from doors, windows and vents, and follow the placement distances in its manual. Never run it in a home, garage or other enclosed space.

A carbon monoxide sensor does not make indoor operation safe.
