What Our Customers Are Saying
Dana C.
Perfect Fit
I was looking for a compact quiet unit and came across RVMP and the Flex Power generator. It runs better than my Honda and saved me money. I called the company before purchase and they gave me confidence that they stand behind their products. I couldn't be more happy!
D.C.
Customer Support at its Finest
I called and explained my needs. They gave me personal service and I purchased the 4500ies. It's way smaller and lighter and I love the telescoping handle on this unit. I have the best portable generator at horse camp.
David C.
Surprised By Power
Much more powerful than my Honda, and actually way quieter. Wish I would have known of this company before I spent 2x on the Honda unit. Two huge thumbs up.
Jim F.
Great Service
Due to the excellent and diligent efforts of Grant and the staff at RVMP I received the 4500 watt generator I ordered well before my departure date. The Onan generator in my RV went out while en-route to Florida. What a blessing they are.
Ken
Great Generator
Great generator, very quiet.
Frequently Asked Questions
Use this text to share information about your product or shipping policies.
How long has Flex Power been around?
Flex Power is a division of RVMP, the leading generator producer for RV original equipment manufacturers. We have been designing and producing portable and install generators since 2017. All our generator technology is road tested and built to last the long haul.
What appliances can the 4500ies power?
It's suitable for many household needs like running a refrigerator, microwave, some window AC units, and smaller power tools. You can also use it for job sites, RVs, tailgates, or during power outages.
What is the CO Guard carbon monoxide shut-off?
CO Guard technology monitors the accumulation of carbon monoxide, a poisonous gas produced by engine exhaust when the generator is running. If CO Guard detects unsafe elevated levels of CO gas, it automatically shuts off the engine.
Do you provide a warranty?
Absolutely. Every RVMP Flex Power generator comes with a 60-day money-back guarantee and a 2-year warranty covering manufacturing defects. If something's not right, we'll make it right — no long forms, no runaround, just real support from a real team based here in the USA.
What is your return policy?
We offer a 60-day money-back guarantee, no questions asked. Prefer to exchange instead? We've got you covered there too. Our goal is to keep every customer powered up, not stuck in the dark.
