Runtime and fuel
The fuel tank holds 8.3 gallons of gasoline. At half load, it runs about 8 hr 50 min on a full tank. That is about 0.94 gallon per hour at half load, or 23 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.
Noise level
The manufacturer does not publish a noise figure for this model. Open-frame generators of this size typically run around 70 to 76 dB(A) at 23 feet; our noise score treats a missing figure as below average.
Outlets and home connection
Its panel offers 4 × 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, 12 V DC outlet. 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.
Starting, safety and warranty
It has electric push-button start, with a recoil cord as backup. 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 $1,200–$1,800: good value per watt?
Relative to its running watts, the DuroMax XP12000EH scores 8.4/10 on value: a good result. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
