The right generator,
before the lights go out.

Pros

• +48–57 dBA — the benchmark everyone else measures against
• +Legendary starting and longevity; GX120-derived engine
• +47 lb, one-hand carry

Cons

• −Roughly double the cost per watt of very good competitors
• −1,800 running watts won't run an RV air conditioner alone

Pros

• +9,500W running / 12,500W peak on gasoline — starts central AC units with a soft-start kit
• +Dual fuel: propane keeps you running when gas stations are down
• +Remote start fob plus push-button electric start

Cons

• −224 lb — two people or the wheel kit to move it
• −74 dBA is loud; this is not a campground machine

Pros

• +24kW covers most homes completely — AC, well pump, kitchen, everything
• +Mobile Link WiFi monitoring with weekly self-test reports
• +Largest dealer/installer/parts network in the category

Cons

• −Installation adds $3,000–$6,000+ — get quotes before ordering the unit
• −67 dBA at 23 ft under load — siting and local noise codes matter

Pros

• +120/240V dual-voltage output from one unit — feeds a transfer switch directly
• +4,000W continuous handles essentially every household appliance
• +4,096Wh LFP base, expandable with extra batteries for multi-day capacity

Cons

• −Serious money — and expansion batteries add four figures more
• −115 lb: mobile on wheels, memorable on stairs
