The Westinghouse WGen10500TFc is a high-capacity portable generator designed for serious home backup, jobsite use, and emergency preparedness. In its open box form, it becomes an even more attractive option for buyers looking to save money while still getting near-new performance. This review takes a deep dive into what this generator offers, how it performs, and whether an open box unit is worth considering.
Product Overview
The WGen10500TFc is a tri-fuel portable generator capable of running on gasoline, propane, or natural gas. It delivers up to 13,500 peak watts and 10,500 running watts on gasoline, placing it firmly in the upper tier of portable generators.
Open box units are typically lightly used or returned items, often with minimal runtime and cosmetic wear. In most cases, they retain full functionality and come at a significantly reduced price compared to brand-new units.
Build Quality and Design
The first thing you notice about the WGen10500TFc is its sheer size and rugged construction. This is not a lightweight or compact generator—it’s built for serious workloads.
The steel frame is solid and durable, designed to withstand outdoor use and transportation. The 500cc OHV engine features a cast iron sleeve, which contributes to long-term durability and reliability under heavy loads.
Despite its weight, portability is manageable thanks to heavy-duty wheels, a folding handle, and a lift bracket. These features make it possible to reposition the generator without excessive effort, though it’s still best handled by two people when lifting.
Power Output and Performance
This generator is designed to handle demanding power needs. With 10,500 running watts on gasoline, it can comfortably power:
- Central air conditioning units
- Refrigerators and freezers
- Sump pumps
- Electric water heaters
- Multiple household circuits simultaneously
The tri-fuel capability is a standout feature. You can switch between fuel types depending on availability or preference:
- Gasoline offers maximum output
- Propane provides cleaner burning and easier storage
- Natural gas allows continuous operation when connected to a home supply
The ability to switch fuels without shutting down the unit adds flexibility that many generators in this class lack.
Runtime and Efficiency
Runtime is another strong point. On gasoline, the generator can run for extended periods on a full tank under moderate load, making it suitable for overnight or multi-day outages.
Propane runtime is shorter but still practical for extended use, while natural gas offers effectively unlimited runtime if your supply remains uninterrupted.
This flexibility makes the WGen10500TFc particularly appealing for emergency preparedness, where fuel availability can become unpredictable.
Ease of Use and Features
Westinghouse has included several user-friendly features that make this generator easier to operate than many competitors.
Electric start with a remote key fob allows you to start the generator from a distance, which is especially useful during storms or harsh weather. There is also a backup recoil start for reliability.
The control panel is well laid out and includes:
- Multiple household outlets
- A 50-amp outlet for transfer switch connection
- Transfer switch-ready design for home integration
- USB ports for small electronics
A built-in display provides real-time information such as voltage, frequency, and total runtime hours, helping you monitor performance and maintenance needs.
Safety Features
Safety is a major consideration with large generators, and the WGen10500TFc includes several important protections.
A built-in carbon monoxide sensor automatically shuts down the unit if dangerous levels are detected, adding an essential layer of safety for residential use.
Low oil shutdown helps protect the engine from damage, and GFCI outlets reduce the risk of electrical hazards.
Noise Level
This generator is not quiet and falls in line with most open-frame generators in its class. The noise level is noticeable and may not be ideal for close residential use without proper placement.
This is the trade-off for high power output. It is acceptable for emergency use, job sites, or when positioned at a distance from living areas.
Open Box Value
One of the biggest advantages of purchasing the WGen10500TFc as an open box unit is the price savings.
Open box models are often significantly discounted compared to new units, sometimes by hundreds of dollars. Many are essentially like-new, with minimal usage and only minor cosmetic imperfections.
However, there are a few trade-offs:
- Shorter warranty periods are common
- Packaging may be missing or replaced
- Accessories or manuals might not always be included
That said, many open box units are tested for functionality before resale and still provide excellent value.
Pros
The biggest strength of this generator is its versatility. The tri-fuel capability gives you unmatched flexibility during emergencies.
Power output is more than sufficient for most homes, even allowing multiple large appliances to run simultaneously.
The remote start feature, long runtime, and transfer switch readiness make it highly practical for real-world use.
Open box pricing makes it one of the best values in its class for those willing to accept minor cosmetic imperfections.
Cons
The generator is heavy and not easily portable without assistance.
Noise levels are relatively high, which may be an issue in quiet residential areas.
It is not as clean in power output as inverter generators, making it less ideal for sensitive electronics without additional protection.
Open box units may have limited warranties and missing accessories, depending on the seller.
Final Verdict
The Westinghouse WGen10500TFc is a powerhouse generator that excels in flexibility, output, and reliability. For homeowners preparing for outages or anyone needing serious portable power, it delivers outstanding performance.
Choosing an open box version can significantly increase its value, offering near-new capability at a reduced cost. As long as you are comfortable with the potential trade-offs in warranty and packaging, it is a smart and practical investment.
For those who need a dependable, high-output generator with the ability to run on multiple fuel sources, the WGen10500TFc stands out as one of the most capable options available in its class.
