Choosing the Right LP Gas Portable Generator
Understanding Your Power Needs
Before diving into features, determine what you need to power. Are you looking for a generator for occasional camping trips, emergency home backup during outages, or to power tools at a job site? This dictates the wattage you’ll require. Calculate the total wattage of all the appliances/devices you plan to run simultaneously. Remember to account for starting wattage, which is often higher than running wattage for motors (like refrigerators or air conditioners). Choosing a generator with insufficient wattage will lead to overload and potential damage.
Fuel Options: Gasoline, Propane, and Natural Gas
A key decision is fuel type. LP gas (propane) generators offer several advantages. Propane is often cheaper than gasoline, and it stores for longer periods without degrading, making it ideal for emergency preparedness. Propane also burns cleaner than gasoline, resulting in fewer emissions and potentially longer engine life. However, propane generators typically produce slightly less wattage compared to gasoline. Dual-fuel generators offer the best of both worlds, allowing you to switch between gasoline and propane depending on availability and price. Natural gas is another option, but requires a direct connection to a natural gas line, limiting portability.
Wattage & Surge Capacity: Matching Power to Demand
Wattage is crucial. Running watts indicate the continuous power the generator can supply. Surge watts (or peak watts) are the maximum power available for a short burst, needed for starting appliances with motors. A higher surge wattage is essential if you need to start multiple appliances simultaneously. For example, a whole-home generator (like the DuroMax XP13000EH) prioritizes high wattage, while a smaller, budget-friendly option (like the WEN 5,600-Watt) may suffice for essential circuits.
Key Features to Consider
- Outlets: The number and type of outlets matter. Standard 120V outlets are common, but consider if you need 240V for larger appliances (requiring a transfer switch) or an RV-ready 30-amp outlet.
- Starting Method: Electric start (with a key or remote) is convenient, while recoil (pull) start is more reliable in emergencies. Some generators offer both.
- Runtime: Measured in hours at a specific load (usually 50% or 25%). A longer runtime reduces the need for frequent refueling. Tank size and fuel efficiency significantly impact runtime.
- Inverter Technology: Inverter generators (like the Westinghouse 8200 Peak Watt Inverter) produce cleaner power (low THD – Total Harmonic Distortion), making them safe for sensitive electronics like laptops and smartphones. They are also generally quieter and more fuel-efficient.
- Safety Features: Carbon monoxide (CO) shutdown sensors are essential for preventing CO poisoning. Automatic low-oil shutdown protects the engine from damage.
