Conventional vs. Inverter: Decoding Generator Types
Before diving into specific models, it’s crucial to understand the two main types of generators Powerhorse offers. This fundamental distinction will shape your entire buying decision, impacting everything from the devices you can power to the noise level and fuel efficiency.
Portable (Conventional) Generators: Raw Power on Demand
Conventional portable generators are the workhorses of the power world. They directly produce AC current, offering substantial power output, often exceeding 10,000 watts. These generators are built for situations where sheer power capacity is paramount, such as backing up an entire home during an outage, powering heavy-duty tools on a construction site, or running multiple high-demand appliances.
Key Characteristics:
- High Power Output: Excellent for powering larger loads, including multiple appliances or tools simultaneously.
- Less Fuel-Efficient: They typically run at a constant engine speed (often 3600 RPM) regardless of the load, leading to higher fuel consumption.
- Louder Operation: The constant high engine speed means they are generally noisier than inverter generators.
- Bulkier Design: Larger engines and fuel tanks make them heavier and less portable, though most Powerhorse portable models come with wheel kits.
- Not for Sensitive Electronics: The "dirty" power (higher total harmonic distortion) can be risky for delicate devices like laptops, smartphones, or modern TVs.
Inverter Generators: Clean, Quiet, and Efficient
Inverter generators represent a more modern approach to portable power. Instead of directly producing AC current, they convert energy through a three-phase process: high-frequency AC, then DC, and finally, a stable AC current. This multi-step conversion results in significantly cleaner power with minimal harmonic distortion. Think of it like a perfectly smooth electrical current, ideal for sensitive electronics.
Key Characteristics:
- Clean Power: Produce electricity with very low total harmonic distortion (THD), making them safe for computers, smartphones, and other sensitive electronics.
- Fuel-Efficient: Variable engine speed (Engine Smart Control) allows the generator to adjust RPMs based on the power demand, saving fuel and extending run times.
- Quiet Operation: Lower engine speeds when less power is needed contribute to significantly quieter operation, making them perfect for camping, RVs, or tailgating.
- Compact & Portable: Generally lighter and smaller, often designed with convenient handles for easy transport.
- Parallel Capability: Many inverter models can be linked together (using a parallel kit) to combine their power output, offering flexibility without buying a single, larger unit.
- Lower Max Wattage: Typically range from 1,200 to 7,500 watts, making them suitable for many common applications but less so for whole-home backup.

Powering Your Life: What Wattage Do You Really Need?
The single most important decision in buying a generator is determining your wattage needs. Overestimate, and you waste money and fuel; underestimate, and you'll be left in the dark.
Here’s how to calculate your needs:
- List Essentials: Make a list of all the appliances and tools you plan to run simultaneously.
- Find Starting & Running Watts: Each item has two wattage ratings:
- Starting (Surge) Watts: The brief burst of power needed to start motor-driven appliances (refrigerators, pumps, power tools). This is usually 2-3 times higher than running watts.
- Running (Rated) Watts: The continuous power needed to keep the appliance operating.
- Calculate Total Running Watts: Add up the running watts for all items you'll use at the same time.
- Add the Highest Starting Watts: Identify the item with the highest starting wattage on your list. Add only that one starting wattage to your total running watts. This gives you your minimum surge requirement.
Example Scenario:
- Refrigerator: 800 running watts / 2,000 starting watts
- TV: 100 running watts
- Lights: 200 running watts
- Phone Charger: 10 running watts
Total Running Watts: 800 + 100 + 200 + 10 = 1,110 watts
Highest Starting Watts (Refrigerator): 2,000 watts
Minimum Generator Size: Needs to handle 1,110 running watts and surge up to 2,000 watts.
General Wattage Recommendations: - 2,500 watts: Ideal for RVs, camping, tailgating, and boating. You'll power lights, small appliances, and charge devices. Always check your specific RV appliance requirements.
- 3,500-5,000 watts: Great for powering well water pumps, gas/electric heaters, refrigerators, microwaves, and most household appliances during an outage.
- 7,500+ watts: Suitable for more extensive home backup, running multiple large appliances, central AC (check specific AC unit wattage), or demanding job site tools.
