The size Honda skips.

Between the $2,799 EU3200i and the $4,999 EU7000iS, Honda sells nothing. Right in that gap sits the most home-backup-sized generator we make: the FlexPower 4500ies — 4,500 peak watts, electric start, dual fuel option, 78 lbs. For $879.

SOUND CHECK — DECIBELS AT 23 FT

Listen to nature, not the generator

Honda built its name on "Super Quiet." FlexPower meets National Park Service sound standards — quiet enough to hold a conversation next to, in the same band as Honda's best. Bars show each maker's published range from light load to full load.

2,200W CLASS

For scale: a quiet dishwasher is about 60 dB, normal conversation about 55 dB. Every generator here runs below or at conversation level at 23 feet.

Figures from each brand's published specs; load levels and test conditions differ between makers.

Why Flexpower?

Dual fuel — at any priceHonda doesn't sell a dual-fuel inverter generator. Period. FlexPower's 4500ies and 6500ies run gas or propane — and propane is the fuel that's still fresh when the storm finally comes.
Electric start at $879Push-button starting begins at $4,999 in Honda's inverter lineup. In ours it begins at $879 — because nobody wants to yank a pull cord in the rain at 2 AM.
More budget for upgradesSkip the Honda badge and you've paid for a transfer switch, a generator canopy, years of fuel — or a second FlexPower generator and the parallel kit to join them.

Four sizes. One fits your home.

Every model: quiet inverter power, CO auto-shutoff, and free shipping in the contiguous U.S.
