Power Output: Peak vs. Running Watts
Peak watts handle startup surges for appliances like refrigerators and air conditioners, while running watts sustain continuous operation. For home backup, a 4000-5000 peak watt generator can power a refrigerator, a few lights, a sump pump, and a furnace fan simultaneously. For example, a 5000-watt peak generator (3900 running watts) can run a 700-watt refrigerator (surge 2200 watts), a 1500-watt well pump (surge 3000 watts), and 500 watts of lights and electronics, staying within its running capacity.
Fuel Type: Dual Fuel Flexibility
Dual fuel generators run on gasoline or propane, giving you options during fuel shortages. Propane stores indefinitely and burns cleaner, but provides slightly less power (about 10% less). Gasoline is more energy-dense and easier to find in emergencies. All three Westinghouse models here are dual fuel, so you can switch based on availability.
Noise Level and Runtime
Inverter generators like these operate at around 52 dBA, which is quieter than a normal conversation and suitable for residential areas. Runtime varies by load and tank size: the iGen5000DF and iGen5000DFc run up to 18 hours on a 3.4-gallon tank at 25% load, while the iGen4000DFc runs up to 7 hours on its 1.69-gallon tank. Economy mode further extends runtime by adjusting engine speed to load.
Portability and Start Options
All three models feature a telescoping handle and never-flat wheels for easy movement. Remote start via key fob, electric start, and recoil start give you flexibility. The LED data center displays fuel level, power output, remaining run time, voltage, and lifetime hours, helping you manage usage.
Safety Features: CO Sensor
Carbon monoxide sensors automatically shut down the generator if CO levels become dangerous, a critical safety feature for home use. The iGen4000DFc and iGen5000DFc include this sensor; the iGen5000DF does not. For indoor-adjacent use or if you have children or pets, a CO sensor is highly recommended.

Frequently Asked Questions
Can I run a refrigerator on a 4000-watt generator?
Yes, a 4000 peak watt generator (3300 running watts) can easily power a refrigerator (typically 600-800 running watts, 1200-2200 surge) along with several lights, a sump pump, and a furnace fan. Always check the starting wattage of your appliances and stay within the generator’s running capacity.
How long does a propane tank last on a dual fuel generator?
Runtime depends on load and tank size. On a 20-pound propane tank at 50% load, a 4000-watt generator typically runs 5-8 hours, while a 5000-watt model runs 4-6 hours. Using economy mode and lower loads extends runtime. For longer backup, consider larger tanks or a dual fuel setup with gasoline.
Is a CO sensor necessary on a home backup generator?
Yes, a CO sensor is highly recommended for any generator used near living spaces. It automatically shuts down the unit if carbon monoxide levels become dangerous, protecting you and your family. Models like the iGen4000DFc and iGen5000DFc include this feature. For more safety tips, see our best dual fuel portable generators for whole house guide.
What is the difference between peak watts and running watts?
Peak watts (or surge watts) are the extra power needed to start motor-driven appliances like refrigerators and air conditioners. Running watts are the continuous power needed to keep them running. A generator must have enough peak watts to handle startup surges and enough running watts to sustain the total load. Always size your generator for the highest surge wattage plus the sum of all running watts.
