Westinghouse IGEN2200 vs Honda EU2200I Because it provides cleaner electricity, an inverter generator can be more fuel-efficient than a fixed-speed generator (reduced electrical noise, voltage fluctuations, and frequency changes). Normal generators generally work continuously at 3600RPM to produce 60Hz power (60Hz x 60s/m = 3600). When demand is low, an inverter generator may operate at a reduced speed, so enhancing its efficiency.If it states it can resist 2000W or 2200W, it may just be an error, as it is the surge load required to start the device. The lower the Watt value, the greater the amount of power available for nearly continual use. The closer an electrical load gets to its maximum rated load of 1800W, the more probable it is that the circuit breaker may trip due to overload (s). Other considerations are air temperature/ventilation, heat dissipation, and the circuit breaker's capacity to maintain 18A (2160W) forever. 1800W divided by 120 volts = 15 amps, however this is not an exact amount. My opinion is not based on reliable data.I utilise this equipment with my vacation trailer. It powers the refrigerator and the lights. Only one or two more appliances (coffee maker, toaster, hair curler) were in use concurrently. I wouldn't use this to power my refrigerator or other household appliances (go bigger). This is the first time I've ever used this machine. Please consider feedback from other users of this device; they may be more aggressive than I am. My last generator was only 1000i; please take feedback from other users of this device; they may be more aggressive than I am. Boost available power and amperage by combining the iGen2200 with the Westinghouse WH2200iXLT, iGen1200, iGen2200, or iGen2500 (Requires Westinghouse Parallel Cord) All Westinghouse Portable Generators are Factory Functionally Tested and May Contain Minimal Oil and/or Fuel Odor; EPA and CARB Compliant; Three-Year Limited Service, Labor, and Parts Coverage and Nationwide Customer Service Network Your quietness will be appreciated by your neighbours. The EU2200i emits noise between 48 to 57 decibels, which is softer than a normal conversation. It is perfect for camping, RV electricity, and any other activity that requires silence. Honda's inverter technology offers dependable, environmentally-friendly energy in a smaller, lighter package. Honda's precision inverter technology enables our inverter generators to supply electricity that is just as reliable as the power from your home's outlets.
