How long does it run on a tank?

The fuel tank holds 1.3 gallons of gasoline. At half load, it runs about 5 hr 35 min on a full tank. That is about 0.23 gallon per hour at half load, or 5 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 WEN 56432i 4500W Inverter 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 2 × 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 starts with a recoil (pull) cord. The manufacturer does not list a CO shutoff sensor: be strict about placement, 20 feet from the house with the exhaust pointed away. 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 WEN 56432i 4500W Inverter scores 7.9/10 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.
