How do you choose the best portable generator?
Choose the best portable generator by matching its running watts, starting capacity, fuel and outlets to the loads you expect to power. A high peak watt number by itself doesn't tell you whether the generator can sustain those appliances.
Write down each appliance and check its running and starting requirements on its label or in its manual. Add the running watts for appliances that will run together, then make sure the generator can also handle the largest startup demand.
Leave room for loads that may cycle on while other equipment is already running. If your plan is for a house, our guide explains how many watts you need to run a house; for refrigeration, see what size generator a refrigerator needs.
Are running watts more important than peak watts for portable generators?
Running watts show how much power a generator can provide continuously, while peak or starting watts cover a brief startup demand. Compare your steady load with the running rating, then check whether the generator can handle the largest startup draw.
Use the ratings for the fuel you intend to use. Several dual-fuel models provide less running output on propane than on gasoline.
Should you choose gasoline, propane or dual fuel for a portable generator?
Dual fuel gives you a choice between gasoline and propane, though the watt output and runtime can vary by fuel. Consider which fuel you can store and supply safely, then compare the rating for that fuel with your load list.
A gasoline-only inverter can still be the right pick if its output, outlets and runtime fit your plans. Read our propane vs gas generator guide for a closer look at the fuel tradeoffs.
What outlets should you check on a portable generator?
Match the generator outlet to the appliance cord or approved connection equipment you plan to use. RV owners often need a TT-30R, while home backup may need a compatible transfer-switch connection.
A transfer-switch-ready outlet doesn't make it safe to connect a generator directly to home wiring. Never feed generator power into a wall outlet; have a qualified electrician install compatible equipment.
How should you set up and place a portable generator?
Set up a portable generator outdoors, away from doors, windows and vents, and follow the manual's instructions. Keep exhaust away from people and occupied spaces even if the generator has a carbon monoxide shutdown feature.
Before a power outage, choose a stable outdoor location and check that the cords or approved connection equipment will reach without blocking doors or paths. Our generator placement guide explains how to keep it safely away from a house.
If you use an extension cord, choose one rated for the generator's output and the connected load. Follow our guide to choosing a generator extension cord and the cord manufacturer's instructions.
What care helps a portable generator stay ready?
Follow the generator manual for oil, fuel, inspection and storage steps. Before using a unit for the first time, complete the required assembly and setup, check fluid levels as directed, and learn its start and shutdown process.
Use fresh, suitable fuel and store it safely according to the manual and local rules. If the generator has a fuel-shutoff feature, use it as directed; WEN says the feature on its inverter models uses remaining carburetor fuel before shutdown to help limit stagnant-fuel buildup.
Run through the startup process before an emergency so you can find the controls and check the outlet connections. Keep the manual with the generator and follow the manufacturer's maintenance schedule.
What mistakes should you avoid when buying or using a portable generator?
The most common sizing mistake is choosing by peak watts alone. Check running watts, startup demand and the rating for your chosen fuel before deciding what can run together.
Another mistake is assuming an outlet makes a connection compatible. Confirm the plug, voltage and amperage requirements for your appliance or transfer switch, and use a qualified electrician for a home connection.
Don't place a generator near an opening or use a CO sensor as a substitute for distance and outdoor operation. Finally, account for weight and storage before buying: a 220 or 245 lb model needs a different plan than a 39 lb inverter.
Which best portable generator should you choose?
Choose the Westinghouse 12500W if your home load plan needs high output, dual-fuel flexibility and multiple outlet types. Pick the iGen4500 for an inverter with an RV outlet and long stated gasoline runtime, or the WEN 2350W if you need to power only a small set of essentials.
For a lighter dual-fuel RV option, compare the Champion 4000W and WEN 3600W against your fuel-specific load needs. Before buying, confirm startup watts, outlet fit and a safe outdoor location, then see our best portable generators for a house guide for more home-focused choices.

Frequently asked questions
What size portable generator do I need for my house?
Choose a generator by adding the running watts of the appliances you need and allowing for their starting watts. A refrigerator, sump pump and furnace can have different startup demands, so check their labels and manuals before selecting a generator.
Our guide to estimating household generator watts walks through that process.
Is an inverter generator better than an open-frame generator?
An inverter may be a better fit if you value a lower stated noise level, easier transport or clean power for electronics. Larger open-frame models in this roundup offer more output for a home backup plan.
Compare rated watts, outlets, fuel, size and your load list before choosing.
Can a portable generator power a refrigerator?
Yes, if the generator can cover the refrigerator's running and startup watts along with any other loads connected at the same time. Check the refrigerator label or manual and leave capacity for startup demand.
Can I connect a portable generator to my home's wiring?
A portable generator can supply home wiring through a compatible transfer switch installed by a qualified electrician. Never connect a generator directly to a wall outlet, and follow local requirements and the generator manual.
For outdoor placement, read how far a generator should be from the house.
Can I run a portable generator near an RV?
Use the generator outdoors and follow its manual and campground rules for placement. Keep it away from doors, windows and vents so exhaust can't enter occupied spaces.
Check your RV's power needs and plug type before choosing an inverter with a TT-30R outlet.
