How long does it run on a tank?
The fuel tank holds 1.6 gallons of gasoline. The manufacturer quotes 7 hr 30 min at a quarter load. At half load, it runs about 5 hr on a full tank. That is about 0.32 gallon per hour at half load, or 8 gallons for a full day of running, so plan your fuel storage for a multi-day outage.
62 dB(A): how loud is it?
The manufacturer rates the A-iPower SUA4300i at 62 dB(A), usually measured at 23 feet (7 m) and a light load. That is about the level of a conversation or a dishwasher: acceptable at a campground.
Outlets and home connection
Its panel offers 2 × 120 V household outlets (5-20R), L5-30R 30 A 120 V twist-lock, USB ports, 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. It is parallel capable: linked to a second compatible unit with a parallel kit, the two outputs combine.
Start type, CO shutoff and warranty
It starts with a recoil (pull) cord. A CO shutoff sensor stops the engine if carbon monoxide builds up around it; it does not replace distance (20 feet from the house) and CO alarms indoors. It is listed as CARB compliant, so it can be sold in California. The warranty runs 3 years (residential use).
Typical price $500–$800: good value per watt?
Relative to its running watts, the A-iPower SUA4300i scores 7.2/10 on value: an average result. Inverters always cost more per watt than open frames: compare it with other inverters. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
