What will a 4,800-watt generator run?

The WEN DF480iX 4800W Dual Fuel Inverter with CO Watchdog delivers 4,000 W continuously and up to 4,800 W for a few seconds to start motors on gasoline. On propane, the manufacturer rates it at 3,600 running watts (4,320 W starting), 10% less. It handles 12 of the 14 loads on our typical list one at a time; add up the running watts of everything you run together, plus the extra starting watts of the biggest motor. As an inverter, it produces clean power suited to laptops, TVs and furnace control boards.

Fuel tank and runtime

The fuel tank holds 1.9 gallons of gasoline. At half load, it runs about 7 hr on a full tank. That is about 0.27 gallon per hour at half load, or 7 gallons for a full day of running, so plan your fuel storage for a multi-day outage. On propane, a standard 20 lb tank holds about 4.7 gallons of LP; propane does not go stale, which makes it the easiest fuel to stock.

62 dB(A): how loud is it?

The manufacturer rates the WEN DF480iX 4800W Dual Fuel Inverter with CO Watchdog 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: home, RV and tools

Its panel offers 4 × 120 V household outlets (5-20R), TT-30R 30 A RV outlet, 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. The TT-30R outlet plugs straight into a 30 A RV. It is parallel capable: linked to a second compatible unit with a parallel kit, the two outputs combine.

5

Start type, CO shutoff and warranty

It has electric push-button start, with a recoil cord as backup. 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).
