Gasoline generators offer the most power per dollar but consume fuel quickly at 0.5-0.75 gallons per hour under load. Propane models run cleaner and store fuel indefinitely, though they produce 10-15% less power than gas equivalents.
Dual-fuel generators give you flexibility to switch between gasoline and propane based on availability and storage needs. Diesel units provide superior fuel efficiency and longevity but cost significantly more upfront.
Noise Levels and Environmental Impact
Most portable generators produce 65-75 decibels at 23 feet, which sounds like a vacuum cleaner running constantly. Inverter generators reduce noise to 50-60 decibels through variable engine speed and better muffling systems.
Carbon monoxide poses a deadly risk in enclosed spaces. Always position generators at least 20 feet from living areas with exhaust pointing away from buildings. Modern units include CO shutdown sensors, but proper placement remains critical for safety.
Maintenance Requirements and Longevity
Regular oil changes every 50-100 hours keep engines running smoothly, while fuel stabilizers prevent carburetor clogging during storage. Quality generators last 1,000-2,000 hours with proper maintenance, making them reliable backup power for years.
Monthly start-ups prevent fuel system issues, and seasonal tune-ups ensure peak performance when you need it most. Budget $100-200 annually for maintenance supplies and occasional repairs on units seeing regular use.
Hand-Crank and Pedal-Powered Generators: Human-Powered Independence
When all other power sources fail, your own muscle power becomes the ultimate backup. Hand-crank and pedal-powered generators offer complete energy independence without fuel costs or weather dependencies.
