Fuel tank and runtime
The fuel tank holds 1.1 gallons of gasoline. At half load, it runs about 6 hr on a full tank. That is about 0.18 gallon per hour at half load, or 4 gallons for a full day of running, so plan your fuel storage for a multi-day outage.
Noise level
The manufacturer does not publish a noise figure for this model. Open-frame generators of this size typically run around 70 to 76 dB(A) at 23 feet; our noise score treats a missing figure as below average.
Outlets: home, RV and tools
Its panel offers 2 × 120 V household outlets (5-20R), 12 V DC outlet. It has no 240 V outlet: it runs plug-in appliances through extension cords, not hardwired circuits or a 240 V well pump.
Start type, CO shutoff and warranty
It starts with a recoil (pull) cord. The manufacturer does not list a CO shutoff sensor: be strict about placement, 20 feet from the house with the exhaust pointed away. It is listed as CARB compliant, so it can be sold in California. The warranty runs 1 year (residential use).
