Price Comparison
The PowerSmart 3800 Watt Dual Fuel Inverter Generator is significantly cheaper than the Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator. Priced at $449.99, the PowerSmart generator is approximately 55% less expensive than the Westinghouse model, which retails for $999.00. This price difference makes the PowerSmart a more budget-friendly option, particularly for consumers who need a generator for occasional use, such as camping or tailgating, rather than extensive home backup.
Power Output
In terms of power output, the Westinghouse generator clearly outshines the PowerSmart model. The Westinghouse offers a peak wattage of 12,500 watts and running watts of 9,500 when using gasoline. In contrast, the PowerSmart provides a maximum of 3,800 surge watts and 3,300 rated watts with gasoline, which is significantly lower. This substantial difference in output means that the Westinghouse can handle larger appliances and more demanding power needs, making it better suited for home backup applications.
Fuel Versatility
Both generators are dual fuel, allowing users to switch between gasoline and propane. The PowerSmart produces 3,800 surge watts with gasoline and 3,500 with propane, while the Westinghouse offers 12,500 peak watts with gasoline and 11,200 with propane. While both models provide flexibility in fuel choice, the Westinghouse's higher output capacity makes it more versatile for users who may need to power larger appliances or multiple devices simultaneously.
Noise Level
The PowerSmart generator operates at a noise level of 70 dB at 23 feet, making it a quieter option compared to many generators on the market. This is particularly beneficial for users who plan to use the generator in residential areas or quiet campgrounds. The Westinghouse does not provide specific noise level data, but typically, larger generators like this one may produce higher noise levels than smaller units. If noise is a significant concern, the PowerSmart may be the better choice for those who prioritize a quieter operation.
Portability
The PowerSmart generator is designed with portability in mind, weighing just 50.7 lbs and featuring a compact design. This makes it easier to transport for activities such as camping or tailgating. In contrast, the Westinghouse is a heavier unit powered by a 457cc engine and equipped with heavy-duty wheels, making it more suitable for stationary use like home backup. While both generators are portable, the PowerSmart's lightweight design gives it an edge for users who require mobility.
Safety Features
Safety is a crucial consideration for any generator. The PowerSmart model includes a built-in Carbon Monoxide (CO) shutdown sensor, which automatically powers off the generator if dangerous CO levels are detected. It also features overload protection and low-oil shutoff for added safety. The Westinghouse generator, while lacking specific CO detection features, boasts automatic low oil shutdown and a digital hour meter for monitoring usage. Both generators prioritize user safety, but the PowerSmart's CO sensor offers an additional layer of protection.
Ease of Use
When it comes to ease of use, the Westinghouse generator has the upper hand with its remote start feature, allowing users to start the generator from a distance with a key fob. This is particularly useful for users who may not want to go outside in adverse weather conditions. Additionally, it comes with a plug-and-play setup, including a battery charger and minimal assembly required. The PowerSmart, while easy to use, relies on a manual start system, which may not be as convenient for all users.
Which should you buy?
Choosing between the PowerSmart 3800 Watt Dual Fuel Inverter Generator and the Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator ultimately depends on your specific needs. If you are looking for a budget-friendly, portable generator primarily for occasional use, the PowerSmart is an excellent choice at $449.99. However, if you require a generator for extensive home backup or need to power larger appliances, the Westinghouse, with its superior output and remote start capability, justifies its higher price of $999.00. Each has its merits, but understanding your power requirements will guide you to the right decision.
