The Generac IQ3800 is one of my favorite dual-fuel inverter choices when you care about clean power for TVs, computers, and smart appliances. It’s a closed-frame design that runs quiet for its size, and the electric start with auto choke made operation impressively easy.
Pros
+Low THD (less than 3%) for sensitive electronics
+Quiet closed-frame inverter design for its size
+Electric start and auto choke worked quickly (about 4–5 seconds)
+Easy fuel switching between gasoline and propane
+LED display shows hours, gasoline fuel level, and load gauge to avoid overload
Cons
-No propane fuel gauge on the display
-Higher-end feature set may cost more than budget models
