Fuel tank and runtime
The fuel tank holds 6.3 gallons of gasoline. The manufacturer quotes 20 hours at a quarter load. At half load, count on roughly 12 hours (our estimate from the quarter-load figure). That is about 0.50 gallon per hour at half load, or 12 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 GXS5000 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.
Can you connect it to your house?
Its panel offers 4 × 120 V household outlets (5-20R), TT-30R 30 A RV outlet, L5-30R 30 A 120 V twist-lock. It has no 240 V outlet: it runs plug-in appliances through extension cords, not hardwired circuits or a 240 V well pump. The TT-30R outlet plugs straight into a 30 A RV.
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 $300–$500: good value per watt?
Relative to its running watts, the A-iPower GXS5000 scores 9.2/10 on value: one of the best results in our catalogue. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
