Fuel tank and runtime
The fuel tank holds 2.2 gallons of gasoline. The manufacturer quotes 14 hours at a quarter load. At half load, count on roughly 8 hr 50 min (our estimate from the quarter-load figure). That is about 0.26 gallon per hour at half load, or 6 gallons for a full day of running, so plan your fuel storage for a multi-day outage.
61 dB(A): how loud is it?
The manufacturer rates the Champion 201318 4500-Watt RV Ready Inverter at 61 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), TT-30R 30 A RV outlet, 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.
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 EPA compliant; check California availability if you live there. The warranty runs 3 years (residential use).
Typical price $500–$800: good value per watt?
Relative to its running watts, the Champion 201318 4500-Watt RV Ready Inverter scores 6.0/10 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.
