Buying Guide for 2026
Running vs Starting Watts
Understanding the difference between running (rated) watts and starting (surge) watts is crucial when selecting a generator for whole home backup. Running watts represent the continuous power a generator can supply to keep appliances running, while starting watts cover the extra power needed to start motor-driven devices like refrigerators, sump pumps, or air conditioners. A generator with a higher starting wattage can handle the initial surge without stalling, ensuring your essential equipment turns on reliably during an outage.
For typical home backup, look for a generator that provides at least 4,000 to 5,000 running watts and 5,500 to 6,500 starting watts. This range can power lights, a refrigerator, a furnace fan, and a few electronics simultaneously. Smaller inverter models like the Honda EU2200i are excellent for sensitive electronics but may not handle larger loads. Always calculate the total wattage of the devices you plan to run and choose a generator with a comfortable margin above that figure.
Fuel Type and Runtime
Portable generators typically run on gasoline, propane, or a dual-fuel setup. Gasoline is widely available and offers high energy density, but it has a shorter shelf life and can be harder to store. Propane burns cleaner and lasts indefinitely in tanks, making it a good choice for emergency preparedness. Some generators offer both options, giving you flexibility depending on what fuel is accessible during an outage.
Runtime at half load is a key metric: a larger fuel tank means longer operation between refills. For whole home backup, look for generators that can run 8 to 12 hours at half load. Models like the WEN GN5600 provide up to 12.5 hours of runtime, reducing the need for frequent refueling. Also consider fuel efficiency and whether the generator has an eco-throttle mode that adjusts engine speed to match load, saving fuel and reducing noise.
Noise Level
Noise is a major consideration for home backup generators, especially in residential neighborhoods or during nighttime use. Inverter generators are generally quieter than conventional models, with sound levels around 50 to 60 decibels at quarter load, comparable to a normal conversation. Conventional generators can reach 70 to 80 decibels, similar to a vacuum cleaner or lawn mower.
If quiet operation is a priority, look for generators labeled as “super quiet” or “inverter” type. The Honda EU2200i is renowned for its whisper-quiet operation, making it ideal for overnight use or close proximity to living spaces. Always check the manufacturer’s decibel rating and consider your local noise ordinances before purchasing.
Portability and Weight
Since portable generators are meant to be moved from storage to outdoor use, weight and design matter. Lightweight inverter models weigh around 40 to 50 pounds and often feature a suitcase-style handle for easy carrying. Larger conventional generators can weigh over 100 pounds and typically include wheel kits and foldable handles for transport.
For whole home backup, you may need a generator that stays in one place, but portability is still valuable for repositioning or taking on trips. Consider the terrain of your property: wheel kits with large tires are better for grass or gravel. If you plan to move the generator frequently, a lighter model like the Pulsar 2300W or PowerSmart 1200W may be more convenient.
Outlets and Transfer Switch Compatibility
The outlet panel determines what devices you can power directly and how you connect to your home’s electrical system. Look for a mix of standard 120V household outlets, a 30-amp RV outlet (TT-30R), and a twist-lock outlet (L5-30R) for transfer switch connection. A transfer switch allows you to safely power hardwired circuits in your home without dangerous backfeeding.
Generators like the WEN GN5600 come transfer-switch-ready, simplifying installation. If you plan to power individual appliances directly, ensure the generator has enough outlets for your needs. Some models also include USB ports for charging phones and tablets directly. For more on this, see our guide on best home generators backup options.
Inverter vs Conventional
Inverter generators produce cleaner power with lower total harmonic distortion (THD), making them safe for sensitive electronics like laptops, TVs, and medical devices. They are also more fuel-efficient and quieter than conventional generators. However, they typically have lower maximum wattage output and higher upfront cost.
Conventional generators are more affordable per watt and can handle larger loads, making them suitable for powering heavy-duty appliances like well pumps or central air conditioners. They are noisier and produce power that may not be stable enough for some electronics. For whole home backup, a conventional generator with a transfer switch is often the most practical choice, while an inverter generator is better for portable use or powering sensitive devices.
