Generac iQ3500

4.7(1,900 reviews)

Generac's premium inverter was built to beat Honda's EU3000iS on paper — more starting watts, electric start, a PowerDial that combines start/run/stop in one twist, and a digital dashboard showing watts and runtime — and owner reviews suggest it largely succeeds at 50-52 dB. Job-site users like the steel enclosure; tailgaters like that it's genuinely conversation-quiet in economy mode. It starts 13.5k RV ACs and the 30A L5-30R twist-lock feeds RV adapters cleanly. The persistent owner complaints: 109 pounds with no wheels and only two handles — moving it solo is miserable and a wheel-kit is the first accessory everyone buys; the carburetor demands fuel treatment before storage; and a 2023-era recall on certain units (stator faults causing fire risk) rattled confidence, though current production is clear. At street prices near $1,250 it undercuts what the equivalent Honda cost by nearly half.

Generac GP3300i
$599
Inverter Generator
4.6(1,500)

Generac's play for the Honda EU2200i shopper who balks at $1,200: 2,500 running watts (700 more than the Honda), PowerRush surge tech, USB ports, and COsense CO shutdown for roughly half the money, in a 60-lb suitcase. Owners use it for camping, tailgates, and charging batteries off-grid, and reviews are broadly positive about starting behavior and the extra headroom that runs a small AC or space heater the Honda can't. What the threads flag: Generac doesn't publish a noise spec — owners measure it audibly louder than the Honda, especially outside eco mode; eco mode can hunt/surge with cycling loads like fridges; the 1-gallon tank is small; and while the 3-year warranty is real, portable warranty service goes through Generac's dealer network, which prioritizes standby customers. A rational value pick if ultimate quiet isn't the goal.

Portable Generator
4.6(2,600)

The big-box storm generator: when a hurricane is three days out, this is what's stacked on pallets at Home Depot, and that availability is genuinely part of its value. 8,000 running watts, 10,000 starting via PowerRush, electric start, COsense shutdown, and an L14-30R for interlock feeding — a complete storm kit under $1,000 from a brand every service shop knows. Owner reports are solid on power delivery: it carries fridges, window ACs, well pumps, and furnace blowers simultaneously. The honest ledger: it's an open-frame roarer (Generac publishes no dB figure; owners report it's loud), non-inverter power means owners keep sensitive electronics on a UPS, it's gasoline-only with a thirsty 420cc engine, and Generac portables were hit by recalls (2022 handle pinch; an April 2026 carburetor fuel-leak recall on certain GP units) — check your serial. Runs forever with oil changes, per multi-year owners.

Generac Guardian 10kW
$4,619
Home Standby Generator
4.8(3,400)

The entry point to the Guardian line, and the one owners of smaller homes keep recommending because it bundles a 100-amp, 16-circuit transfer switch in the box. The 460cc G-Force 400 engine covers essentials — furnace, fridge, well pump, some lights — not whole-house AC, and owners are clear-eyed about that. At 61 dB it's the quietest Guardian, though people still report it's louder than they expected during weekly exercise. Owner threads praise years of flawless auto-transfers, but the recurring gripes are real: the battery, oil, and some setup parts aren't included, Evolution controller boards have a documented failure pattern, and warranty service depends entirely on how good your local Generac dealer is. Budget for install — most people pay more for wiring and gas work than for the unit.
