Choosing the Right Powerhorse Generator
Power Output & Fuel Type
The most crucial factor is determining your power needs. Think about what appliances or devices you absolutely need to run during an outage or on the go. Add up their wattage (starting and running wattage – starting wattage is often higher). Powerhorse generators range from 5000W to 12000W. A larger wattage provides more flexibility, but also means a higher price and greater weight. Consider if you need a generator solely for essential appliances (lights, fridge) or more demanding ones (air conditioners, power tools).
Dual fuel capability (gasoline and propane) is a significant benefit offered by many Powerhorse models. Propane burns cleaner and stores longer, making it ideal for extended outages, but typically delivers slightly less power than gasoline. The ability to switch between fuels without shutting down is a huge convenience. If you already have a propane supply, a dual-fuel generator can be very cost-effective.
Power Quality (Total Harmonic Distortion – THD)
Sensitive electronics – smartphones, laptops, TVs – require “clean” power to operate safely. This is measured by Total Harmonic Distortion (THD). Lower THD percentages are better. Powerhorse inverter generators boast very low THD (less than 3%, some even below 2%). Traditional generators typically have higher THD, which could damage sensitive devices. If you plan to power electronics, an inverter generator is a must-have.
Starting Method & Convenience
Powerhorse generators offer both recoil (pull) start and electric start options. While recoil start is reliable, electric start is considerably easier, especially for those who may have difficulty with physical exertion. Note that electric start models usually require a 12V battery (sometimes sold separately) and add to the overall cost. Some models, like the 5000W, even include a wireless remote start/stop, which is incredibly convenient for remote operation.
Safety Features
Safety should be a top priority. Powerhorse generators include several important safety features:
- Carbon Monoxide Monitoring: Essential for preventing CO poisoning when used in enclosed spaces.
- Automatic Voltage Regulation (AVR): Maintains a stable voltage output, protecting your appliances from damage.
- Overload Protection: Prevents the generator from being overloaded, which could cause a fire or damage the generator itself.
Other features to consider:
Engine Size
Noise Level
Portability (weight and handle design)
Runtime (fuel efficiency)
Copper-wound heads (for durability)
