How to choose the right one
-
Check your power needs
You must match the generator’s wattage to your actual load. The Westinghouse 6600-Watt Remote Start Generator offers 6600 watts, which suits most home backup scenarios. If you need more power, the 28000-Watt model supports heavy jobsites or whole-home backup. Inverter models like the 5000-Watt Inverter Generator provide clean power for sensitive electronics. Always calculate your total wattage requirement before buying to avoid underpowered or oversized units.
-
Verify fuel flexibility
Most options on this list run on gas, but some offer dual fuel capabilities. The Westinghouse 4650W Dual Fuel Portable Generator allows you to switch between fuel types, which adds convenience if gas supplies are limited. Other models, such as the 12500W Gas Generator, are gas-only. Choose dual fuel if you value backup fuel options. Stick with gas if you prefer simpler maintenance and consistent performance from a single fuel source.
-
Consider portability limits
Weight and dimensions determine how easy the unit is to move. The Westinghouse 5000-Watt Inverter Generator with Remote Start weighs only 105 pounds, making it suitable for RV camping. In contrast, the 28000-Watt model weighs 541 pounds and is fixed for home use. Measure your storage space and check the weight limit if you plan to move the generator. Heavier units offer more power but require a permanent or semi-permanent setup.
-
Use remote start
All models in this guide include remote start and electric start options. This feature lets you operate the generator from a distance, which is useful for home backup during storms. You do not need to go outside to start the unit. This convenience is standard across the list, from the budget-friendly 5000W Inverter to the premium 10000W Open Frame Inverter. Remote start pairs well with auto choke for fully automatic operation.
-
Prioritize safety features
Look for built-in CO sensors and automatic shutdowns. The Westinghouse 6600-Watt Remote Start Generator includes a CO sensor to protect you from carbon monoxide poisoning. Several other models, like the 12500W Gas Generator, also feature this safety mechanism. Auto choke simplifies startup by adjusting the fuel mixture automatically. These features ensure safer operation, especially when running the generator indoors or in enclosed spaces with proper ventilation.
Frequently asked questions
What does auto choke do on a generator?
Auto choke adjusts the fuel-air mixture as the engine warms up. This allows the generator to start easily and run smoothly without manual intervention. You do not need to pull a cord or adjust a lever yourself. The system handles the transition from cold start to steady operation automatically.
