Runtime and fuel
The fuel tank holds 7.5 gallons of gasoline. At half load, it runs about 9 hr on a full tank. That is about 0.83 gallon per hour at half load, or 20 gallons for a full day of running, so plan your fuel storage for a multi-day outage.
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), L14-30R 30 A 120/240 V twist-lock. The L14-30R 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.
Start type, CO shutoff and warranty
It has electric push-button start, 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. The warranty runs 3 years (residential use).
Typical price $800–$1,200: good value per watt?
Relative to its running watts, the DEWALT DXGNR8000 scores 8.1/10 on value: a good result. Generator prices on Amazon move a lot, especially before hurricane season: check the current price before you buy.
