Power output: running and starting watts

The maXpeedingrods MXR4000 4000W Inverter delivers 3,200 W continuously and up to 4,000 W for a few seconds to start motors. 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 1.1 gallons of gasoline. The manufacturer quotes 7 hr at a quarter load. At half load, it runs about 4 hr on a full tank. That is about 0.27 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.

Outlets and home connection

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.

5

Safety features 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 1 year (residential use).
