Buying Guide
What matters most when choosing a 12000-watt generator
Fuel type: Dual-fuel options offer flexibility during fuel shortages or storage constraints. Gasoline provides broad availability, while propane can be stored longer and is less volatile.
Power needs: Ensure the unit can handle your essential circuits. Look for continuous running watts (not just peak watts) to estimate how long you can run critical appliances during an outage.
Key features to compare
- Outlets: Count and type of outlets (120V, 120/240V, twist-lock, RV outlets) for your devices and home panels.
- Starting method: Electric start is convenient; manual recoil is cheaper but requires more effort during outages.
- Safety: CO sensors, shutoffs, and proper ventilation reduce risk in occupied spaces.
- Runtime: Look for fuel tank size and efficiency to estimate how long the generator runs between fills.
- Portability: Wheel kits and handle design affect maneuverability for outdoor use or job sites.
Placement and installation considerations
- Place generators outdoors in a well-ventilated area, at least 15 feet from living spaces and doors.
- Use a transfer switch or interlock kit to connect to the home electrical system safely.
- Regular maintenance, fuel stabilization, and periodic test runs help ensure reliability in emergencies.
Fuel storage and accessibility
Keep multiple fuel containers in approved, ventilated storage and rotate fuel periodically to prevent stale fuel issues. LPG and propane storage can be a practical option for long-term availability in many regions.
Frequently Asked Questions
