Very pleased with this. Used it to power my RV and did some boondocking. Struggles for a moment when the AC kicks in, as expected, but gets through it and runs everything just fine. It’s pretty quiet (for a generator), especially when not running a big load.

So we bought this Gen for a hunting trip in the desert where temps will exceed 100. We currently have a Honda 3000 that we love but this one was purchased to abuse on this upcoming trip. I have not had the trip yet as it’s in September but I have used it at our property for the break in and then to power tools.
The Champion 4500W has been excellent for me. It starts easily, is quiet and has good power to connect refrigerator, lights and small air. I like that it works with gasoline or propane and consumes little. A little heavy, but very reliable. Totally recommended.

I love this Gen because I am too old to be using something that is not easy to start or take care of. This one I can roll around on its wheels, starts easy, it battery life is amazing – I can run my RV all night without a refill, the power will run my fridge, microwave, fans, TV, and a window air unit.
I live in Florida where hurricanes happen, so a generator is a must. This is my third generator and a better machine than the rest. It starts immediately with the electric start and runs both propane and gas beautifully. I detach the battery when not in use so that it doesn’t run down from sitting.

Complete Buying Guide for 4500 Watt Inverter Generators for RV
Essential Factors We Consider
When picking a 4500 watt inverter generator for your RV, think about power output, noise level, fuel type, portability, and safety.

Also, check run time, weight, and ease of use—electric start can be a game-changer in cold weather.
Budget Planning
Prices range from budget-friendly to premium. Set a budget based on what you need. Basic models cost less but might lack dual fuel or electric start. Mid-range options offer a good balance. Remember, investing in a reliable generator saves you from breakdowns on the road. Consider long-term costs like fuel efficiency and maintenance.
