Buying Guide
Rated Watts Versus Surge Watts
Surge watts are the short burst a generator can deliver to start motors, typically for a few seconds. Rated (running) watts are what it can sustain. When sizing, add the running watts of every load you plan to run at once, then add the surge requirement of the largest motor. A refrigerator may need roughly three times its running watts at startup, so a 7,000-surge, 5,000-rated unit can handle more motor loads than a 4,500-watt continuous model.

Noise Level in Decibels
Generator noise is measured in decibels at a set distance, usually around 23 feet, under a specified load. Lower numbers mean quieter operation. Inverter generators with noise ratings in the low 60s are often noticeably quieter than open-frame units in the 70s or higher. Remember that a 10 dB difference is perceived as roughly half as loud.

Fuel Flexibility
Dual-fuel generators run on gasoline or propane. Gasoline offers longer runtime per tank in many designs, while propane stores longer and is easier to keep on hand without fuel degradation. Owners in areas prone to fuel shortages often value the second option. If you use propane, confirm the regulator and hose are rated for the generator’s input.

Outlet Configuration and Voltage
Check whether you need 120V only or 120/240V. Most household appliances run on 120V, but well pumps, large air conditioners and electric dryers often require 240V. A 120/240V unit like the 10,500-surge model covers both, but must be connected through a properly installed transfer switch for home use. Never backfeed a house through a standard outlet.

Electric Start Versus Recoil Start
Electric start uses a battery and a button, which is easier for many users and helpful for cold starts. Recoil start needs no battery but requires physical effort and can be harder in cold conditions. Electric start models need the battery kept charged and checked periodically.

Portability and Size
Weight and frame size determine whether you can realistically move the unit alone. Smaller portable frames suit camping, tailgating and jobsite use. Larger units are better kept as semi-permanent backup, ideally on a level surface with a weather-resistant cover designed for airflow.

Safety Features and Placement
Carbon monoxide is the most serious hazard with any gasoline or propane generator. Look for CO shutdown or CO sensing, and always operate the unit outdoors, at least 20 feet from doors, windows and vents. Keep it dry and never run it inside a garage, even with the door open. Consult a qualified electrician for any permanent home connection.

FAQ
What does dual fuel mean on a generator?
A dual-fuel generator can run on either gasoline or propane. You switch the fuel source depending on what you have available. Gasoline usually gives longer runtime per tank in many designs, while propane is easier to store long term.
Is an inverter generator quieter than a standard generator?
Generally yes. Inverter designs adjust engine speed to the load, which typically produces lower noise and cleaner power. Compare the listed decibel rating at the same distance when judging noise between models.
Can a Powerhorse dual fuel generator power a whole house?
Only partially, and only with planning. Most models on this list are better suited to essential circuits. The 10,500-surge unit has the highest capacity, but whole-home use depends on your total load. Work out your running and surge requirements first and consider an electrician’s help for transfer switch wiring.
How do I know how big a generator I need?
List every appliance you plan to run at once, add up the running watts, and add the largest motor’s startup surge. Choose a unit with rated watts above that total and surge capacity above the peak startup load.
Is propane or gasoline better for dual fuel use?
It depends on your priorities. Gasoline is often preferred for longer runtime per tank and availability in most areas. Propane stores almost indefinitely and is useful for long-term standby. Many owners keep both options available.
Can I run a generator inside a garage?
No. Generators produce carbon monoxide, which can build up to deadly levels in minutes even with the garage door open. Always operate them outdoors, away from openings, with the exhaust pointed away from the home.
Conclusion
For most home backup buyers, the Powerhorse 8000 Surge Watt Inverter Generator offers the most balanced mix of inverter power, capacity and listed noise level. Buyers who need 240V output and maximum surge should look at the 10,500-surge dual fuel model, keeping in mind the transfer switch requirement. The 7,000-watt electric start unit suits users who prioritize easy starting, while the 4,500-watt dual-fuel model fits essentials-only portable use. The 5,000-surge electric start option is a practical middle choice for those on a tighter budget. Match the unit to your actual running and surge loads rather than the highest wattage you can find.
