Buying Guide for Gas and Electric Generators
Choosing the right gas and electric generator depends on several important factors that ensure reliable power supply and ease of use.
Power Output and Capacity
Assess your power requirements by calculating the total wattage of the appliances and devices you want to run simultaneously. Generators list running watts (continuous power) and peak or surge watts (extra power for startup). Pick a generator with wattage ratings that exceed your needs for safety margin and future expansions.
Fuel Type and Efficiency
Dual fuel or tri-fuel generators provide flexibility by running on gasoline, propane, or natural gas. Gasoline is widely available but less stable over storage. Propane and natural gas are cleaner burning, quieter, and easier to store longer. Consider fuel availability, storage convenience, and runtime per tank.
Start Mechanisms and Portability
Electric start models provide convenience, often accompanied by remote key fobs or push-button ignition. Recoil start is a backup but less user-friendly. If you plan to move the generator frequently, choose models with wheel kits, compact designs, and manageable weight.
Safety Features
Modern generators include important safety protections such as automatic low oil shutdown to prevent engine damage and CO (carbon monoxide) sensors that detect harmful gas levels. Look for generators with transfer switch readiness for safe home integration and outlet covers to protect against moisture.
Noise Levels
Generators vary in noise output. Inverter generators tend to operate more quietly, which is important for camping or residential areas. Check decibel ratings and consider the environmental impact, especially if you live in noise-sensitive neighborhoods.
Transfer Switch Compatibility
If using a generator as a home backup system, ensure it is compatible with transfer switches. This allows safe and efficient power connection to selected circuits and prevents back feeding to the grid, safeguarding utility workers and your equipment.
Durability and Engine Type
Generators with 4-stroke OHV engines and cast iron sleeves provide longer durability and consistent performance. Look for reputable brands with robust construction and maintenance features like digital hour meters for tracking runtimes.
