6 Best Alternatives to the Westinghouse 12500W Gas Generator Remote (2026)

How alternatives compare to the 12500W

Westinghouse 6600-Watt Remote Start Generator

The Westinghouse 6600W model offers 5300 running watts, which is significantly less than the original’s 9500 watts. You give up substantial power capacity but gain a lighter unit at 137 pounds versus 212 pounds. The dimensions are smaller, measuring 20.6 by 23.4 inches. It retains remote start, transfer switch readiness, and the CO sensor. This choice suits buyers who need backup power for fewer circuits or prefer easier maneuverability. If your whole-home load exceeds 5300 watts, this model will not suffice. It is a practical step down for smaller homes or RV use where portability matters more than maximum output.

Westinghouse 28000-Watt Remote Start Gas Generator

This 28000W generator provides far more capacity than the original 12500W unit. You gain substantial power for large homes but accept a massive weight of 541 pounds and larger footprint. The dimensions reach 35 inches wide and 40.4 inches high. It keeps the remote start, CO sensor, and transfer switch ready features. The trade-off is extreme lack of portability. This model fits users who need to power an entire large house during outages and have a permanent or semi-permanent setup. It is not for those needing to move the generator frequently. The high wattage justifies the bulk for critical, high-demand home backup scenarios.

Westinghouse 10000W Open Frame Inverter Generator

The Westinghouse 10000W Inverter Generator uses inverter technology to provide clean power for sensitive electronics. It weighs 148 pounds, which is lighter than the original’s 212 pounds. The footprint is slightly wider at 26.7 inches but shorter in length. It retains remote start, CO sensor, and transfer switch readiness. You trade raw open-frame wattage for cleaner sine wave output. This option suits users who need to run laptops, medical devices, or audio equipment safely. It is also quieter due to inverter design. If you do not need the full 12500W surge and value power quality over sheer capacity, this inverter model is a superior technical choice.

Westinghouse 18000W Gas Generator with CO Sensor

This 18000W generator delivers much higher power than the original 12500W unit. You gain extra capacity for larger loads but accept a weight of 352 pounds. The dimensions are larger, measuring 31 inches wide and 35 inches high. It includes remote start, CO sensor, and transfer switch readiness. The main difference is the increased wattage output. This model fits buyers who need more than 9500 running watts but do not require the 28000W behemoth. It is still heavy and difficult to move. Choose this if your home’s electrical needs exceed the original’s capacity but you want to stay within a manageable, albeit large, footprint.

Westinghouse 5000W Inverter Generator with Remote Start

The Westinghouse 5000W Inverter Generator offers 5000 watts, significantly less than the original’s 9500 watts. You gain a much lighter unit at 106 pounds and a compact design measuring 17.5 inches wide. It retains remote start, CO sensor, and parallel capability. It lacks transfer switch readiness in the listed attributes. This model suits RV travelers and campers who need quiet, clean power for sensitive devices. It is not suitable for whole-home backup due to lower wattage and missing transfer switch support. If you prioritize portability and power quality for recreational use over home backup capacity, this inverter is the better fit.

Westinghouse 12500-Watt Dual-Fuel Generator

The Westinghouse 12500W Dual-Fuel Generator matches the original’s peak wattage but adds fuel flexibility. You can run it on gasoline or propane, unlike the gas-only original. It weighs 210 pounds, slightly lighter than the 212-pound original. The dimensions are identical at 26.1 by 27.2 inches. It includes remote start and transfer switch readiness but does not list a CO sensor in the attributes. This choice suits users who want fuel storage options or cleaner burning propane. If you prefer propane for indoor-safe storage or reduced maintenance, this dual-fuel model offers the same power with added versatility.
