What it can run

Generators are sized in watts. Running watts are what the unit can supply continuously; starting watts are a short surge for motors and compressors. The DuroMax 16,000 Watt Portable Tri Fuel Inverter Generator - Low THD (XP16000iHT) is rated at 13,000 W running and 16,000 W starting.

Wattstanding calculationWattstanding calculation — to size a generator, add the running watts of everything you will run at once, then add the largest single starting surge (starting − running watts) from any one motor. The result must stay within the generator's running and starting watts. Appliance wattages are typical planning values — read the nameplate.

Use the load calculator to total your own appliances.

Fuel and runtime

The maker states a 10.5-gallon tank and up to 18.2 hours at the stated load, which implies about 0.58 gallons per hour at that load.

Wattstanding calculation10.5 gal ÷ 18.2 h = 0.58 gal/h; a full day at that load ≈ 14 gal. Multiply by today's fuel price for a daily cost, or use the fuel calculator.
Seller or manufacturer claim18.2 hrs

Multi-fuel units usually produce less power on propane or natural gas than on gasoline; the maker's per-fuel ratings are the ones to size against.

Connecting it to a home

To power home circuits you need a rated transfer switch or interlock and an inlet, matched to this generator's outlet and amperage, installed by a licensed electrician.

Check the pairing in the generator ↔ transfer-switch compatibility matrix.

SafetyNever plug a generator or battery system into a wall outlet to power the house ("backfeeding"): it can send electricity back into the utility lines and injure line workers, and it can start fires. Connecting a generator to a home's wiring is a job for a licensed electrician, with the permit and inspection your local code requires. Wattstanding does not give wiring instructions.

Safety and placement

SafetyNever run a generator inside a home, garage, basement or any enclosed or partly enclosed space — exhaust contains carbon monoxide, which can kill in minutes. Keep it outdoors, well away from doors, windows and vents, with the exhaust pointed away from the house, and use battery-powered carbon monoxide alarms indoors. Follow the maker's manual and U.S. Consumer Product Safety Commission guidance.

This listing mentions a carbon monoxide shutoff or sensor, which is a useful backup — not a substitute for placing the generator outdoors and keeping working CO alarms inside.
