Two generator classes to compare
Westinghouse WGen9500DF dual-fuel generator
A higher-output gasoline/propane option for a planned home-backup load. Westinghouse lists 9,500 running watts on gasoline and 8,500 on propane. Size the connected loads and starting surge, and arrange proper transfer equipment with a qualified electrician for home circuits. We do not own this generator.

Westinghouse iGen4500DFc dual-fuel inverter generator
A smaller enclosed inverter-generator option when portability and a more limited load plan matter. Verify the exact iGen4500DFc model, fuel-specific rated output and startup capacity at checkout. We have not tested it.

Carbon monoxide safety: Run fuel generators outdoors only, far from doors, windows and vents, with exhaust directed away from occupied spaces. Never run one in a home, garage or enclosed area, even with doors open. Follow the manufacturer’s placement instructions and use working CO alarms. Never backfeed a household outlet.
For indoor, exhaust-free battery operation, compare power stations and refrigerator backup sizing.
The four numbers and decisions that matter
Running watts
Add the continuous wattage of equipment you expect to operate simultaneously. This is the baseline load the generator must sustain.
Starting watts
Refrigerators, pumps, compressors and other motor loads can briefly demand more power when starting. Verify equipment labels or manuals instead of assuming the running number covers the surge.
Essential loads
A refrigerator, lights and internet are a different job from central air, electric water heating and a well pump. Decide what truly needs power before shopping.
Connection method
Extension-cord loads and home circuits are different setups. For home circuits or hardwired equipment, use a properly designed transfer-switch or approved interlock arrangement installed as required.
Build your outage plan before you buy
Write down each essential appliance or circuit and find its rated electrical demand. Avoid treating generic online wattage charts as exact specifications; two appliances that do the same job can have different loads. Your own equipment label or manual is the better source.
Basic essentials
Refrigerator/freezer, selected lighting, modem/router, phone charging and a few outlets can often be managed by deliberately staggering loads.
Motor-heavy loads
Well pumps, air conditioners and compressors deserve extra attention because starting demand can materially change the required generator capacity.
Fuel and runtime
More output generally brings more fuel use, weight and noise. Capacity you will never use can become an expensive burden during storage and refueling.
CO shutoff technology
Automatic CO shutoff is a worthwhile safety feature, but it does not make indoor, garage or near-home operation safe. Correct outdoor placement remains essential.
Portable generator or power station?
If your needs are smaller, quiet battery operation near the appliance may matter more than sustained high output. Fuel generators remain useful when long-duration power and higher loads are the priority, provided fuel storage and safe outdoor operation are practical.
For battery capacity and inverter sizing, see our Portable Power Station Sizing Guide. To plan one common essential load, see whether a power station can run your refrigerator overnight. If you are planning for larger garage tools as part of your backup-power load, our Air Compressor Sizing Guide explains why motor demand deserves special attention.
Our practical sizing rule
Buy for the load plan, not the biggest number on the box. Total what will actually run together, verify startup demand, leave sensible operating headroom and make sure the connection method is appropriate. If the plan involves energizing home circuits, have a qualified electrician handle the connection design or installation.

Match the generator to your outage plan
These are use-case recommendations based on the buying criteria above, not hands-on product tests. Check the current manufacturer specifications and the exact model before ordering.
Portable generator for selected loads
List simultaneous running loads and the largest starting load, then compare rated running watts rather than peak watts. Decide how you will connect appliances safely before buying.
Watch out: Never run it indoors, in a garage or near openings.
Inverter generator for lighter loads
For smaller loads where noise and portability matter, compare rated output, fuel use at realistic loads and service access.
Watch out: High-draw household equipment may exceed its output.
Power station for indoor essentials
For electronics and selected smaller loads, compare continuous output, surge rating and usable watt-hours using the runtime method in our power-station guide.
Watch out: Battery capacity limits long outages without a recharge plan.
Compare battery runtime in the power-station sizing guide.
