What the wattage figures mean
Running watts show how much power a generator can supply continuously. Starting watts cover the extra power some appliances need when motors kick on. Propane also delivers less power than gasoline: about 10% less for the Champion 201503 and Westinghouse WGen3600DFcv, and 5% less for the DuroMax XP4850EH. If you're using propane, size your load around its lower wattage rating.
Compare runtime at the same load
Runtime figures depend on the load. Westinghouse lists 16.5 hours on propane at 25% load, while Champion lists 10.5 hours at 50%. Since the tests use different loads, the figures aren't directly comparable. Your actual runtime will depend on the appliances you're running and how often they cycle on and off. For more details, see this guide to propane vs. gas generators. For the final decision, use the manufacturer's own specifications for the exact model you're considering.
Running a Dual Fuel Generator Safely at Home
Generator exhaust contains carbon monoxide, an odorless gas that can cause serious illness or death. The U.S. Consumer Product Safety Commission (CPSC) warns about CO poisoning and fire hazards associated with portable generators. A CO shutoff can add protection, but it doesn't make indoor operation safe.
Follow these placement and operating rules
Portable generators produce carbon monoxide and can pose fire and electrical hazards if used incorrectly. Follow these safety rules to protect your household during an outage.
Keep the generator outdoors. Operate it at least 20 feet from your home and other buildings. Point the exhaust away from doors, windows, and vents.
Never run it in an enclosed space. A garage, basement, shed, crawlspace or enclosed porch can allow deadly exhaust to build up, even if a door is open.
Install working alarms. Keep CO and smoke alarms on every level of the home, and test them monthly.
Choose a model with CO shutoff protection. Champion calls its feature CO Shield, while Westinghouse lists automatic CO shutdown. Follow the owner's manual and remember that these features don't replace household CO alarms.
Avoid backfeeding. Never plug a generator into a regular wall outlet to power household circuits. A licensed electrician can install a compatible transfer switch or interlock.
Turn the generator off before refueling. Let the engine cool first, and follow the manufacturer's instructions for handling gasoline or connecting a propane tank.
The CPSC provides further guidance in its portable generator safety information. Review the manual for your specific model, too. Outlet configurations, grounding instructions, and fuel connections vary. If you need to power household circuits, have a licensed electrician confirm the correct inlet and transfer equipment for the generator's outlet. A 30A outlet alone doesn't mean a generator can safely connect to every home panel.
Keeping essentials running when the generator is off
A fuel generator needs to stop for refueling, maintenance, and cooling. Some households also shut it down overnight to reduce noise. During those gaps, a battery power station can keep selected devices running indoors, provided the loads fit its output and available capacity. EcoFlow's portable power stations offer a separate source of stored electricity. They aren't dual-fuel generators, and they don't replace the generator comparison above. The useful question is which devices need to stay on while the engine is off.
For smaller essentials like lights, phones, and a Wi-Fi router, the EcoFlow DELTA 3 Classic offers a compact backup option. If you also need more output and battery capacity for a compatible refrigerator or additional appliances, the EcoFlow DELTA 3 Max is worth considering.
Labeled runtime estimates (example loads)
The examples below use an assumed 85% usable-energy factor to account for conversion losses. They're estimates, not measured appliance results. Actual runtime depends on the devices, their duty cycles, and operating conditions.
Setup | Calculation | Estimate |
EcoFlow DELTA 3 Classic (1024Wh), lights + phones + router totaling 50W (example) | 1,024Wh × 0.85 ÷ 50W | About 17 hours |
EcoFlow DELTA 3 Max (2048Wh), the same 50W plus a fridge, averaging 150W in total (example) | 2,048Wh × 0.85 ÷ 150W | About 11.6 hours |
Use your devices' labels or manuals to estimate runtime, keeping in mind that refrigerators cycle on and off and may need extra power to start. You can recharge a battery power station from a compatible generator while it runs, but check both units' manuals and never feed power back into your home’s wiring with a makeshift cord. For longer-term backup, explore EcoFlow's home backup solutions and choose a system that fits your essential loads.
How much power does a home need in an emergency?
You don't usually need to run every appliance in the house during an outage. Start with the essentials you need most, such as the refrigerator, a few lights, phone chargers, the router, and, where applicable, a sump pump or furnace blower.


Make a load list before you buy
Before choosing a generator, figure out which appliances you need during an outage and how much power they draw. This quick checklist will help you size the generator correctly and avoid overloading it.
Write down each appliance's running watts. Check the label or owner's manual instead of guessing.
Identify starting watts. Motors and compressors may need a brief surge when they start.
Add the loads you expect to run together. Keep the total below the generator's running-watt rating for the fuel you'll use.
Start with the largest motor load. Once it starts, add other appliances one at a time and watch for overloads.
Plan the connection to your home. A licensed electrician should install the transfer switch or interlock and confirm that the inlet and wiring match the generator's outlet.
If propane will be your main emergency fuel, use the propane wattage figures in the comparison table. The gasoline rating won't help if the combined load exceeds what the generator can supply on propane. You can also separate essential loads between a fuel generator and a battery power station. For example, the generator may run larger appliances while operating, while a charged battery unit keeps a router, lights, and phones on during downtime. That setup requires a realistic load plan and safe, independent connections.
Conclusion
When choosing a dual fuel generator under $1,000, compare propane running watts, starting watts, outlet types, runtime at a stated load, and CO shutoff protection. Confirm current prices and model availability before buying, then size the generator around the appliances you need to run together. For household circuits, have a licensed electrician plan the connection. A battery power station can cover the quieter periods when a fuel generator is off. The EcoFlow DELTA 3 Classic is worth considering for lights, phones, and a router, while the EcoFlow DELTA 3 Max offers more output and capacity when a compatible refrigerator also needs power. Check your actual loads before deciding which setup fits your home.
FAQs
Is a dual fuel generator worth it for home backup?
It can be, especially if you want the choice of gasoline or propane during an outage. Propane is convenient to store when handled correctly, while gasoline provides more running watts on the models compared here. Expect about 5% to 10% less output on propane for these examples.
How many watts do I need to run a house in an emergency?
Add the running watts of the appliances you need to operate at the same time, then check the largest starting load. If you plan to use propane, base your calculations on the generator's propane rating. A small list of essential loads may need far less power than an entire house.
How far from the house should a generator be?
The CPSC says portable generators should operate outdoors at least 20 feet from homes and buildings, with exhaust directed away from openings. Never run one inside a home, garage, basement, shed or other enclosed area.
Do dual fuel generators have a CO shutoff?
Some models do. The Champion 201503 lists CO Shield, and the Westinghouse WGen3600DFcv lists automatic CO shutdown. Check the manufacturer's current specifications for any model you consider. A shutoff feature doesn't replace working CO alarms.
How long does a dual fuel generator run on a 20 lb propane tank?
Runtime depends on the generator's load. Champion lists up to 10.5 hours for the 201503 on a 20 lb propane tank at 50% load. Westinghouse lists up to 16.5 hours for the WGen3600DFcv at 25% load. Since those figures use different loads, they aren't directly comparable.
