Westinghouse WGen11500TFc vs DuroStar DS13000MXT

Comparison Overview

Key takeaways

• Westinghouse WGen11500TFc delivers 11,500 running watts and 14,500 starting watts.
• DuroStar DS13000MXT provides 10,500 running watts and 13,000 starting watts.
• Both are tri-fuel generators, gasoline, propane, or natural gas capable.
• Both are rated at 74 dB, expect noticeable open-frame generator noise.
• Westinghouse runs up to 19 hours at 25% load, DuroStar up to 17 hours.
• DuroStar weighs 211 lb, lighter than Westinghouse at 230 lb.

Best use cases

Choose the Westinghouse WGen11500TFc if you want more breathing room for home backup loads and fewer compromises when multiple things start at once. With 11,500 running watts and 14,500 starting watts, it is better suited to households that want to run a broader mix like a refrigerator, freezer, lights, a microwave, and a well pump or sump pump without constantly managing what is on. The longer stated run times (19 hours at 25% load, 9.5 hours at 50%) also help if you are planning overnight coverage and want fewer refuel cycles. The downside is practicality: at 230 lb and 74 dB, it is a heavy, loud machine, so it is not ideal for frequent loading into a truck by yourself or for noise-sensitive areas.

Choose the DuroStar DS13000MXT if you still want a high-output tri-fuel generator but value easier maneuvering and slightly less heft. At 211 lb, it is still heavy, but it is a bit more manageable for rolling around a garage, driveway, or job site. Its 10,500 running watts and 13,000 starting watts are plenty for many backup setups, especially if you are comfortable staggering big starts (for example, letting the fridge cycle off before starting a pump). You give up some runtime (17 hours at 25% load, 8.5 hours at 50%) and some surge headroom, which can show up most when starting larger motors.

For RV and camping use, neither is a great fit because both are non-inverter and rated at 74 dB, so they are better thought of as home backup or worksite power rather than quiet recreation power.

Verdict & recommendation

If your priority is maximum capacity and a little more run time for home backup, the Westinghouse WGen11500TFc is the safer pick on paper, thanks to 11,500 running watts, 14,500 starting watts, and up to 19 hours at 25% load. If your priority is a slightly lighter, easier-to-handle tri-fuel unit that still delivers serious power, the DuroStar DS13000MXT is a practical alternative at 211 lb with 10,500 running watts and 13,000 starting watts.

Both are equally loud at 74 dB and neither is an inverter, so plan for noise and be mindful with sensitive electronics. In the end, choose Westinghouse for more headroom, choose DuroStar for easier handling and solid high-watt tri-fuel capability.
