Buying Guide: Choosing The Best 12000 Watt Portable Generator
Fuel Type and Flexibility
Generators are mainly available as gasoline-only, dual fuel (gasoline and propane), or tri fuel (adding natural gas). Dual and tri fuel generators provide more fuel options during emergencies, increasing convenience and reducing risks if one type of fuel is unavailable. Propane burns cleaner and has longer shelf life than gasoline.
Power Output and Usage
Check the running watts (continuous power) and starting watts (surge power) needed to run your appliances or tools. A 12,000 watt generator can typically support an entire small- to medium-sized home or a large RV. Assess your essential devices’ wattage to ensure compatibility.
Starting Mechanism
Electric start is highly recommended for ease of use, especially during emergencies when quick power restoration is needed. Some models also include a recoil start as a backup.
Portability and Size
Larger generators output more power but are heavier and bulkier. Look for robust handles, wheels, and frame durability for easier transport if you require mobility.
Safety Features
Consider safety elements like CO alerts or automatic shutoff systems that monitor carbon monoxide levels and improve indoor safety, particularly for home backup usage.
Noise Levels
Generators produce noise; opt for quieter models if used in residential areas or campgrounds. Noise levels are usually measured in decibels (dBA).
Weather Protection
Investing in a waterproof and windproof generator cover is wise to protect your unit from the elements, prolonging its lifespan.
Transfer Switch Compatibility
If you plan to connect the generator directly to your home’s electrical system, ensure it is transfer switch ready, simplifying safe power transfer.
