DuroMax XP15000HXT review: our full analysis

12,000 running watts: what can it power?

The DuroMax XP15000HXT delivers 12,000 W continuously and up to 15,000 W for a few seconds to start motors on gasoline. On propane, the manufacturer rates it at 11,400 running watts (14,250 W starting), 5% less. On natural gas: 10,260 running watts (12,825 W starting). It handles 14 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.

Typical figures; check the label of your own appliances. One load at a time: add up everything you run together.

Fuel tank and runtime

The fuel tank holds 13.2 gallons of gasoline. The manufacturer quotes 18 hours at a quarter load. At half load, it runs about 12 hours on a full tank. That is about 1.10 gallon per hour at half load, or 26 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.

78 dB(A): how loud is it?

The manufacturer rates the DuroMax XP15000HXT at 78 dB(A), usually measured at 23 feet (7 m) and a light load. That is loud, like a lawn mower: place it as far from the house and the neighbors as the cords allow.

Outlets: home, RV and tools

Its panel offers 10 × 120 V household outlets (5-20R), L5-30R 30 A 120 V twist-lock, L14-30R 30 A 120/240 V twist-lock, 14-50R 50 A 120/240 V. The 14-50R outlet supplies 120/240 V, which is what a manual transfer switch or an interlock kit with a power inlet box connects to, installed by a licensed electrician. Never backfeed the house through a wall outlet.

Safety features and warranty

It starts with a remote key fob or the electric push-button, 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 5 years (residential use).

Typical price over $2,500: good value per watt?

Relative to its running watts, the DuroMax XP15000HXT scores 5.9/10 on value: a high price per watt, which its other strengths may justify. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
