When it comes to RV power, size matters, just not the way you think.
Meet the Flex Power® 4000eM, the most compact 4000-watt RV generator on the market. Tipping the scales at just 110 lbs and measuring only 22" x 16.9" x 13.4", this install-ready unit punches above its weight, delivering serious power in a footprint smaller than most 2800W competitors.
Whether you're building out a van, upgrading your towable rig, or outfitting your toy hauler, the 4000eM gives you:
-
EFI performance for smoother starts and better fuel efficiency
-
Dual fuel flexibility (Gasoline/LP)
-
50-state CARB compliance for peace of mind
-
Whisper-quiet operation for off-grid or campground chill
This isn’t just a generator—it’s a game-changer for the RV crowd that refuses to compromise. Small size. Serious output. Flex-worthy performance.
