DuroMax XP15500HXT Tri Fuel Portable Generator
Keep larger household loads in your outage plan
When your backup plan includes a well pump, refrigeration, and several essential circuits, both sustained output and fuel flexibility matter. The XP15500HXT combines a 12,000W gasoline running rating with propane and natural-gas capability. Use its fuel-specific ratings below to size the actual loads you intend to support rather than treating the model’s peak wattage as continuous capacity.
Choose your fuel and size your loads
Peak output covers brief starting demand. Running output is the sustained limit, and it changes with the fuel. Add the running watts of simultaneous loads, allow for motor starts, and check the rating of the outlet and cable you will use.
| Fuel | Starting / peak watts | Running watts |
|---|---|---|
| Gasoline | 15,500 W | 12,000 W |
| Propane | 14,500 W | 11,500 W |
| Natural Gas | 13,000 W | 10,500 W |
The manufacturer rates gasoline operation at 10.5 Hrs. at 50% load. Actual runtime varies with load, fuel, temperature, and operating conditions.
Natural-gas installation requires 6 to 9 inches of water column supply pressure and a supply sized for 278,000 BTU/hr. Have a qualified gas professional check the meter, line size, and other appliances sharing the supply.
Check the fit before you order
- Have a qualified electrician select the transfer switch or interlock, inlet, and cable for home connections. These are separate installation items; never backfeed a wall outlet.
- Each receptacle has its own current limit. Multiple outlets do not increase the generator’s total running capacity.
- Allow room to move and operate the generator safely. The wheel kit assists positioning; this is still heavy equipment.
