More Details on Our Top Picks

  1. Westinghouse 18000 Peak Watt Dual Fuel Portable Generator with Remote Start and CO Sensor

    Westinghouse 18000 Peak Watt Dual Fuel Portable Generator with Remote Start and CO Sensor

    Best Overall for Large Homes and Outdoor Use

    View Latest Price

    This model stands out for its impressive power output, offering up to 18,000 peak watts on gas—a clear advantage over smaller generators like the WEN 5600-Watt. Its dual fuel capability provides flexibility, and remote start adds convenience during emergencies. The inclusion of a CO sensor enhances safety, especially for outdoor or semi-enclosed spaces. However, at 74 dBA, it’s notably loud, making it less suitable for quiet neighborhood settings. Additionally, its weight and size make transportation a challenge, requiring planning for mobility. The large 10.5-gallon tank ensures extended runtime, but this also adds to its bulk. Compared to the DuroStar DS13000MX, it offers higher wattage but sacrifices portability and noise comfort. This generator makes the most sense for homeowners needing serious power for outdoor events or larger properties where noise isn’t a primary concern.

    Pros:
    • Extremely high power output suitable for large homes
    • Dual fuel flexibility with gas and propane
    • Remote start and safety sensors including CO detection
    • Multiple outlets for various appliances
    Cons:
    • Very loud at 74 dBA, less neighborhood-friendly
    • Heavy and bulky, difficult to move around
    • Longer setup time due to size and weight

    Best for: Large households and outdoor enthusiasts needing high wattage with safety features

    Not ideal for: Urban dwellers or those with limited storage space where noise and size are critical

    • Peak Watts (Gas):18,000
    • Running Watts (Gas):14,500
    • Peak Watts (Propane):16,000
    • Running Watts (Propane):13,000
    • Tank Capacity:10.5 gallons
    • Engine:713cc Westinghouse V-Twin OHV
    • Noise Level:74 dBA
    • Outlets:120/240V 14-50R, 120/240V L14-30R, 120V L5-30R, GFCI duplex, USB ports

    View Latest Price

    This generator excels in offering flexible fuel choices—gasoline, propane, or natural gas—making it ideal for homeowners who want to avoid fuel shortages. Its remote electric start simplifies operation, especially during stressful outages, and a runtime of up to 19 hours surpasses many competitors like the WEN 5600. Compared to the larger Westinghouse 18000 Peak Watt model, it sacrifices some peak wattage but gains in fuel versatility and longer run times. Its more substantial weight and initial setup complexity might deter users seeking a portable solution, but for whole-home backup, these tradeoffs are manageable. Safety features like CO shutdown and automatic low oil shutdown add peace of mind. This pick is best for homeowners prioritizing fuel flexibility and extended autonomy over sheer power capacity.

    • Presence of fuel odor after manufacturing

    Best for: Homeowners needing reliable, versatile backup with long runtime and multiple fuel options

    Not ideal for: Users who prioritize portability and lightweight design for frequent moving

    • Peak Watts (Gasoline):13500
    • Running Watts (Gasoline):10500
    • Peak Watts (Propane):12500
    • Running Watts (Propane):9500
    • Peak Watts (Natural Gas):10000

    View Latest Price

    This generator offers a balanced mix of power and portability, making it suitable for mid-sized homes or RV owners. Its 14.5-hour runtime on a 4.7-gallon tank is impressive for its size, and the dual-fuel capability adds flexibility. Compared to the larger Westinghouse models, it’s easier to move around but still provides enough wattage for essential home circuits or RV appliances. The inclusion of a CO sensor and transfer switch readiness enhances safety and convenience. Its weight, however, means it’s less ideal for frequent mobility without assistance. Its price point is higher than basic models like the WEN 5600 but justified by safety features and dual fuel support. This generator is ideal for users who want a reliable backup that balances capacity with portability.

    Pros:
    • Dual-fuel operation for versatility
    • Long runtime of up to 14.5 hours
    • Safety features including CO sensor and low oil shutdown
    • Transfer switch-ready for easy connection
    Cons:

    This model offers a solid balance of power and affordability, providing 5600 starting watts and 4500 running watts—enough to handle essential appliances during outages. Its electric start simplifies operation, especially for those who dislike pull-starts, and the CO shutdown sensor enhances safety. The 4.3-gallon tank offers up to 12.5 hours of runtime at half load, making it reliable for typical outages. Compared to larger, more expensive units, it’s a practical choice for budget-conscious buyers who still need dependable backup power. Its weight and limited fuel capacity, however, restrict portability and runtime for larger loads. While lacking some fuel options or extended runtime, it fills a critical niche for moderate home backup at a reasonable price point.

    Pros:
    • Decent wattage for home backup
    • Electric start for ease of use
    • Safety features like CO shutdown sensor
    • Up to 12.5 hours of runtime

    Not ideal for: Large homes or users seeking multi-fuel support or extended runtime

    • Power:5600 starting watts, 4500 running watts
    • Engine:224cc
    • Fuel Tank Capacity:4.3 gallons
    • Run Time:up to 12.5 hours
    • Outlets:Two 120V 5-20R, 120V 30-amp TT-30R, 120V 30-amp NEMA L5-30R
    • Warranty:3 years
    Our verdict
    “A cost-effective, reliable backup generator suitable for moderate power needs during outages.”
  5. DuroStar DS13000MX 13,000-Watt Dual Fuel Portable Generator with Remote Electric Start

    DuroStar DS13000MX 13,000-Watt Dual Fuel Portable Generator with Remote Electric Start

    Best for Heavy-Duty Power and Durability

    View Latest Price

    This generator combines high wattage with rugged construction, making it ideal for demanding applications like whole-home backup or job sites. Its 13,000 watts of power can handle large loads, outperforming smaller models like the Westinghouse 6500 Watt. Dual fuel support adds versatility, and electric start with remote control simplifies operation.

    • Transfer Switch Compatibility:Yes
    • Outlet:50-Amp

    View Latest Price

    This model stands out for its impressive dual fuel capacity, delivering up to 12,500 peak watts on gasoline, which is higher than most competitors like the Westinghouse 9500 Watt Dual Fuel generator. Its remote electric start adds convenience when power is critical, and the long runtime of up to 12 hours makes it suitable for extended outages. Compared to smaller models, the 6.6-gallon tank and powerful engine provide a better balance of power and endurance, but its weight and bulk make it less portable. The multiple outlets with safety covers ensure compatibility with diverse devices, yet residual odors from factory testing can be a minor annoyance. Overall, this generator suits users seeking reliable, high-capacity backup that’s easy to start remotely, though portability may be a challenge.

    Pros:
    • High wattage output with dual fuel flexibility
    • Remote electric start for quick operation
    • Multiple outlets with safety covers
    • Extended runtime of up to 12 hours

    The Jackery HomePower 3600 Plus makes this list as the most portable high-capacity power station, offering 3600W output and 3584Wh, surpassing smaller units like the WEN 5600-Watt generator in capacity but with a different approach to backup power. Its lightweight design, combined with wheels and a telescopic handle, makes it easier to move than traditional gas-powered options like the Westinghouse 14500 Watt generator. While it offers multiple charging methods, including solar, its weight of over 77 pounds and limited outlets restrict simultaneous device connections compared to larger generators. External solar panels are required for solar charging, adding to setup complexity. This pick makes the most sense for users who want reliable, quiet, and portable power for emergencies or RV use, but those needing maximum wattage or multiple outlets should consider alternatives.

    Pros:
    • High capacity and expandability up to 21kWh
    • Lightweight and easy to move despite heavy weight
    • Multiple charging options including solar and AC
    • Quiet operation and clean power output
    Cons:
    • Heavy at over 77 pounds despite portability features
    • Limited outlets for multiple device connection
    • Requires external solar panels for solar charging

    Best for: Campers, RV owners, or homeowners prioritizing portability and quiet operation for moderate power needs

    Not ideal for: Users needing to run high-wattage appliances or multiple heavy-duty tools simultaneously

    • Power Output:3600W
    • Capacity:3584Wh
    • Expandable Capacity:up to 21kWh
    • Voltage:120V & 240V
    • Weight:77.16 Pounds
    • Dimensions:15.2 x 12.2 x 19.3 inches
    • Number of Outlets:2
    • Charging Time:AC in 2.5 hours, Solar in 4 hours
    Our verdict
    “This portable power station is perfect for those seeking high-capacity, quiet, and flexible backup power on the go.”
  8. Westinghouse 14500 Peak Watt Tri-Fuel Portable Generator with Remote Electric Start

    Westinghouse 14500 Peak Watt Tri-Fuel Portable Generator with Remote Electric Start

    Best for Versatile Fuel Options and Long Runtime

    View Latest Price

    Compared with the dual fuel models like the B07Q1DLKBG, this tri-fuel generator offers broader fuel flexibility and more power, with up to 14,500 peak watts and a durable 550cc engine. Its ability to run on gasoline, propane, or natural gas provides added convenience during extended outages or jobsite use. The long runtime—up to 19 hours on gasoline—outshines smaller models, and its low THD makes it safe for sensitive electronics. However, its weight and bulk make it less suitable for frequent transport, requiring a sturdy setup. The remote electric start simplifies operation, especially in emergencies. This generator suits users who need maximum fuel versatility and long-lasting power, but portability isn’t its strength.

    Pros:
    • Tri-fuel capability for maximum flexibility
    • Long runtime of up to 19 hours
    • Low THD safe for sensitive electronics
    • Remote electric start for convenience
    Cons:
    • Heavy and bulky for portability

    View Latest Price

    The DuroMax XP13000EH stands out for its impressive surge wattage of 13,000 watts, making it one of the most capable portable generators for whole-home backup among dual fuel options.

Factors to Consider When Choosing Best Home Backup Generators

Choosing the right home backup generator involves considering several key factors that impact performance, safety, and ease of use. Understanding these factors helps prevent common mistakes, such as underestimating power needs or overpaying for unnecessary features. A well-chosen generator provides peace of mind during outages and ensures your home’s critical systems stay operational without complications.

Power Capacity and Size

Assess your home’s essential load and choose a generator with sufficient wattage to power those devices. Larger capacity models can handle whole-home backup, but they tend to be bulkier and more expensive. Conversely, smaller units may only support critical appliances, which is often enough for short outages. Avoid overestimating your needs, as this can lead to unnecessary costs and complexity, but also don’t skimp on capacity if you want to run essential systems seamlessly.

Fuel Type and Run Time

Generators come in gas, propane, and dual-fuel options, each with tradeoffs. Gas generators are common but require refueling during prolonged outages, which can be inconvenient. Propane offers cleaner burning and longer shelf life but may require additional tanks. Dual-fuel models provide flexibility, allowing you to switch fuels based on availability, but they tend to be more complex and costly. Consider your local fuel supply, storage space, and expected outage duration when choosing.

Safety Features and Ease of Use

Features like automatic transfer switches, CO sensors, and remote start can significantly enhance safety and convenience. Transfer switches simplify the connection process, reducing the risk of backfeeding and electrical hazards. CO sensors alert you to dangerous emissions, especially important for indoor or semi-enclosed setups. Remote start adds convenience during emergencies, allowing you to activate the generator from inside the house. Be mindful that these features often increase the purchase price but can save lives and reduce hassle during outages.

Portability and Installation

While portable generators are easier to move and set up, they may not be suitable for permanent backup solutions. Larger, stationary models often require professional installation and dedicated circuits, but they provide more reliable, whole-home power. Consider your space, whether you need a permanent backup or a temporary solution, and your willingness to handle installation complexity. Oversized units may also be overkill for small households, leading to unnecessary expense.

Price and Value

High-capacity, feature-rich models cost more but often deliver better reliability and convenience. Cheaper options may suffice for short-term or partial backup needs, but they risk underperforming during critical outages. Balance your budget with your power requirements and desired features. Investing in a slightly more expensive model with safety enhancements and remote start can provide peace of mind and long-term savings by avoiding frequent replacements or repairs.

Frequently Asked Questions

Can I run my entire home on a backup generator?

Running an entire home requires a high-capacity generator, typically over 10,000 watts, and proper installation with a transfer switch. While some models on this list can handle full-home loads, many are better suited for essential circuits only. It’s important to evaluate your critical appliances and systems, then select a generator that can meet those needs without overloading. Professional assessment and installation ensure safety and optimal performance.

How long can a backup generator run during an outage?

The runtime depends on the fuel tank size and load. Smaller tanks may last only a few hours under full load, while larger tanks or continuous fuel supply can extend operation for days. Always consider fuel availability and plan for refueling if outages are expected to last. Some models feature larger tanks or the ability to connect to external fuel sources, which can significantly increase their runtime during extended outages.

Is a dual-fuel generator worth the extra cost?

Dual-fuel generators offer considerable flexibility by allowing you to switch between gas and propane, which can be useful if fuel supplies fluctuate. They are especially valuable in emergencies when one fuel type becomes scarce. However, they tend to be more expensive and slightly more complex to operate and maintain. If you live in an area prone to long outages or have multiple fuel options available, investing in a dual-fuel model can be a smart choice.

Do I need a professional to install a backup generator?

For large, stationary models with transfer switches, professional installation is strongly recommended to ensure safety and code compliance. Portable generators can often be set up by homeowners, but proper wiring, grounding, and transfer switch hookup should be handled carefully to prevent backfeeding and electrical hazards. Always follow local regulations and manufacturer instructions, and consider hiring a licensed electrician for any permanent or complex setup.

What features should I prioritize for ease of use?

Features like remote start, automatic transfer switches, and integrated CO sensors significantly enhance ease of use and safety. Remote start allows activation from inside, especially during bad weather, while transfer switches simplify connecting to your home’s circuits. CO sensors provide vital alerts for dangerous exhaust buildup, preventing health risks. Prioritizing these features depends on your comfort level with setup and your safety concerns, but they generally improve the overall user experience during power outages.

Conclusion

For most homeowners, the Westinghouse 28000 Peak Watt Portable Home Backup Generator offers the best combination of power and features for whole-home backup. Those seeking a budget-conscious solution can turn to the WEN 5600-Watt Portable Generator, which covers essential needs without breaking the bank. If safety and convenience are top priorities, models with remote start and transfer switches, like the Westinghouse 14500 Peak Watt Tri-Fuel Generator, are worth considering. For complete peace of mind, especially in areas prone to long outages, investing in a high-capacity, dual-fuel, or permanently installed unit can provide reliable backup power tailored to your specific needs.
