Portable Generators
US-market portable gas, dual-fuel, and tri-fuel generators — inverter and conventional — indexed from official manufacturer sources only, with strict safety-field rules: CO-shutdown status is never inferred, runtime always carries its load basis, and running vs starting watts are never collapsed.
Category overview
Portable generators are fuel-burning units spanning quiet suitcase inverters for camping and RV use up to high-output dual- and tri-fuel machines for home backup and jobsites. This category covers standalone base models only: bundles, accessories, transfer switches, whole-home standby units, and onboard RV generators are out of scope. Every core specification is normalized from official manufacturer sources with per-field provenance, and safety-sensitive fields follow stricter publication rules — a model with ambiguous CO-shutdown documentation is not published at all. Fuel generators are outdoor-only equipment: they produce carbon monoxide and are never apartment- or indoor-suitable, which is exactly the kind of cross-category fact this index records explicitly.

Comparisons in this category
Compact Quiet Inverter Generators: Honda EU2200i vs EU2200i Companion vs WEN 56235iX vs Generac iQ3500
Four sub-3,500 W 120 V inverter generators built for quiet recreation, camping, and light backup — all with documented CO-shutdown. They separate on output (1,800–3,000 W running), noise basis (Honda and WEN publish load-based dBA; Generac publishes none), documented THD (only WEN gives a number), weight (17.7–49.5 kg), and receptacle panel.
High-Output Dual & Tri-Fuel Home-Backup Generators: DuroMax XP13000EH vs Westinghouse iGen11000TFc vs WGen9500DF vs Champion 201412 vs DuroMax XP9000iH vs Firman WT05571
Six high-output 120/240 V multi-fuel generators for whole-house backup through a transfer switch — 5,500–10,500 W running, dual- and tri-fuel, conventional and inverter. They separate on output, fuel flexibility, power quality (only the inverters offer clean THD), and one critical safety point: five have CO-shutdown, one documents that it does not.
RV-Ready Generators: WEN DF360iX vs Champion 201531 vs Westinghouse iGen5000DFc vs Firman WT05571 vs Honda EU2200i Companion
Five generators with genuine RV receptacle evidence — a TT-30R (or, for the Honda, a Honda-marketed L5-30R) on the panel, not just 'RV Ready' marketing. They span 1,800–5,500 W running, single- to tri-fuel, and 21.5–59.6 kg, all with documented CO-shutdown.
Looking for zero-emission indoor-safe power?
Battery portable power stations are the fume-free, indoor-usable counterpart to this category. Cross-category recommendation pages that weigh generators against battery units are planned but not yet published — this index does not pretend gallons and watt-hours are the same thing.
Structured attributes in this category
Every product in Portable Generators is indexed against these normalized attributes. Comparison matrices use the same keys, so values are directly comparable across brands.
| Key | Attribute | Unit | Description |
|---|---|---|---|
running_watts | Running (rated) watts | W | Rated continuous output on the primary fuel. Never collapsed with starting watts. |
starting_watts | Starting (peak) watts | W | Peak/surge output for motor start-up. Multi-fuel units store per-fuel figures where officially stated. |
generator_type | Generator type | — | inverter_portable, conventional_portable, or open_frame_inverter. |
fuel | Supported fuels | — | gasoline, propane, natural_gas — from official docs only; conversion kits never imply support. |
fuel_tank_capacity_gal | Fuel tank | gal | Gasoline tank capacity. |
runtime_by_fuel_and_load | Runtime | h | Hours per tank/cylinder, always stored with fuel and load basis (25% / 50%). Basis-free claims are never used. |
voltage | Voltage | — | 120V or 120/240V. |
receptacle_summary | Receptacles | — | NEMA-coded outlet map (5-20R, TT-30R, L14-30R, 14-50R, ...). RV suitability requires receptacle evidence, not marketing. |
thd | Total harmonic distortion | % | Stored only when officially stated numerically; 'clean power' claims never become numbers. |
noise_db | Noise | dBA | Stored with its load/measurement basis; adjective-only 'quiet' claims are ignored. |
co_shutdown | CO shutdown | — | Automatic CO sensing shutoff per official docs (CO-MINDER, CO Shield, CO-SENSE, Watchdog...). Ambiguity blocks publication. |
engine_size_cc | Engine displacement | cc | — |
weight_kg | Weight (dry) | kg | — |
warranty_years | Warranty | years | — |
