Fuel tank and runtime
The fuel tank holds 2.6 gallons of gasoline. The manufacturer quotes 12 hours at a quarter load. At half load, it runs about 8 hr on a full tank. That is about 0.33 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.
68 dB(A): how loud is it?
The manufacturer rates the A-iPower SUA4600iF Open-Frame Inverter at 68 dB(A), usually measured at 23 feet (7 m) and a light load. That is a typical open-frame level, comparable to a vacuum cleaner: fine for home backup at 20 feet, loud for a campground.
Outlets: home, RV and tools
Its panel offers 2 × 120 V household outlets (5-20R), L5-30R 30 A 120 V twist-lock, USB ports. 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.
Starting, safety 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 EPA compliant; check California availability if you live there. The warranty runs 3 years (residential use).
Typical price $300–$500: good value per watt?
Relative to its running watts, the A-iPower SUA4600iF Open-Frame Inverter scores 8.3/10 on value: a good 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.
