Easy to prep and runs well on both fuels
This generator is easy to prepare for service, with a funnel design that is convenient to use. It ran a 15000 BTU air conditioner on a fifth wheel using gasoline with no issues, and the same air conditioner ran without problems on propane. Starting is easy on both fuels, and switching between them is simple. The gas tank is small, but it powered the RV air conditioner for around six hours per tank over multiple days. A 20 lb propane tank lasts a very long time.
Pros
- + easy to prep for service
- + convenient funnel design
- + runs 15000 BTU AC on gasoline without issues
- + runs 15000 BTU AC on propane without problems
- + starts easily on both fuels
- + simple fuel switching
- + around six hours per gas tank
- + 20 lb propane tank lasts a long time

Quiet dual-fuel generators with clean sine wave
These generators produce a clean sine wave and run quietly. Two units are used with a 50 amp parallel kit to keep them synchronized at the same output. They are low enough to fit in a vehicle gear tunnel after removing wheels and rubber bumpers, resting on rubber pads. Running on LP, a 32 amp setting causes overload, so 24 amps works best; a 28 amp option would be ideal. The display and remote start are highly valued. The adjustable portable EV charger has a 50 amp plug and manual current adjustment.
Pros
- + clean sine wave
- + quiet operation
- + parallel kit keeps units synchronized
- + low height fits in gear tunnel
- + display and remote start useful
Cons
- − on LP, 32 amp setting causes overload
- − no 28 amp setting on EV charger

Poor Support and Unresolved Generator Issues
The generator runs on propane but fails to start on gasoline. After requesting a replacement carburetor, the wrong part was sent twice, and the issue remains unresolved after more than six months. The unit was never filled with gasoline before the problem appeared. Support has been unhelpful, and the return window has passed. The experience has been frustrating, especially during hurricane season. A different brand was ultimately purchased to obtain a working generator.
Cons
- − Won't start on gasoline
- − Wrong carburetor sent twice
- − Unhelpful support
- − Unresolved after six months
- − Return window passed

Powerful, compact dual-fuel generators with parallel and series capability
The GM4600iAEDC offers 4600/3800 watts on gasoline and 4200/3500 watts on propane in a package similar in size and weight to the GM3500iAED. Both models feature remote start, dual-fuel operation, and quiet running. The 4600 adds a TT-30R outlet, a 12-volt outlet with USB and USB-C adapter, a front-panel battery charging port, an LED light, and series capability for 240-volt output with a separately sold parallel kit. Build quality is high. The 4600 is preferred for its extra power and capabilities, though the 3500 remains a solid performer.
Pros
- + Compact and lightweight
- + Quiet operation
- + Remote start
- + Dual fuel
- + Parallel and series capable
- + LED light for dark operation
- + Battery charging port
- + Well built

Convenient dual-fuel generator for frequent outages
This generator is convenient for areas with frequent power outages. It rolls on wheels, runs on gas, and can be started and stopped with a remote after connecting an extension cord. It powers four bedrooms with TVs, fans, and lamps, plus a living room with a lamp, Wi-Fi router, and internet box. Computers and monitors set to power on during outages also work. It is not very loud, has handles, and requires little maintenance so far. It can also run a fridge and water pump. The only drawback is that the fuel level indicator is hard to read when filling.
Pros
- + convenient for frequent outages
- + remote start and stop
- + wheels and handles for portability
- + not very loud
- + powers multiple rooms and appliances
- + low maintenance so far
Cons
- − fuel level indicator is hard to read when filling
