Pros
- Both 14-50R and L14-30R outlets fit a 50 A RV or most transfer switches
- Enough for a central air conditioner plus most of a house’s circuits
- Runs on gasoline or propane, so stored fuel never goes stale
- Push-button start, and shuts itself off if carbon monoxide builds up
Cons
- Over 200 lb, so it needs flat ground to wheel around
- Propane lasts only about 5 hours per 20 lb tank at half load
- Not CARB compliant, so California buyers need a different model
