The Smart Shopper’s Guide to Portable Gas Generators
Portable gas generators are lifesavers when the power goes out or when you need electricity far from a wall outlet. Choosing the right one doesn’t have to be tricky. This guide helps you pick the best machine for your needs.
Key Features to Look For
When shopping, focus on these important parts. They tell you how well the generator will work for you.
Power Output (Wattage)
- Starting Watts (Surge): This is the burst of power the generator gives when you first turn on a big appliance, like a refrigerator.
- Running Watts (Continuous): This is the steady power the generator provides while it runs. Always buy a generator with more running watts than you actually need.
Run Time and Fuel Tank Size
How long can the generator run on one tank of gas? A bigger fuel tank means less refueling. Check the run time at 25% and 50% load. More run time is better for long outages.
Noise Level (Decibels – dB)
Generators can be loud. If you plan to use it near your home or neighbors, look for inverter generators. They are much quieter (usually under 60 dB) than traditional open-frame generators.
Outlets and Safety Features
Make sure the generator has the right outlets for your needs (standard 120V, RV outlets, etc.). Safety features like low-oil shutoff and overload protection are essential. These features protect your expensive appliances.
Important Materials and Build Quality
The materials used directly affect how long your generator lasts and how tough it is.
Engine Quality
A good engine lasts longer. Look for well-known brands or engines that use high-quality copper windings in the alternator. Copper handles heat better than aluminum.
Frame and Casing
Most portable generators use a steel frame. This frame protects the engine from bumps and weather. A durable, powder-coated frame resists rust better.
Inverter Technology
If you plan to run sensitive electronics like laptops or TVs, you must choose an inverter generator. Inverter generators produce “cleaner” power, which is safer for modern electronics.
Factors That Improve or Reduce Quality
Quality is often found in the details.
What Improves Quality:
- Automatic Voltage Regulation (AVR): This keeps the electricity output steady, which is good for appliances.
- Electric Start: This feature lets you start the generator with the push of a button, which is much easier than using a pull cord.
- Fuel Gauge: A clear fuel gauge helps you monitor gas levels easily.
What Reduces Quality:
- Lightweight, Thin Plastic Parts: These break easily when dropped or exposed to rough weather.
- No Low-Oil Sensor: If the oil runs out and the engine keeps running, the engine will quickly be ruined. Always check for this sensor.
User Experience and Use Cases
Think about where and how you will use the generator.
Camping and Tailgating
For camping, you need portability and quiet operation. Small inverter generators (under 3000 watts) are perfect. They are light enough to carry and won’t bother other campers.
Home Backup Power
For keeping essentials running during a power outage (like a fridge, lights, and a furnace fan), you need a larger unit, often 5000 to 7000 running watts. These are usually heavier and louder.
Job Sites
Construction sites require durability and high power. Look for heavy-duty frames and GFCI (Ground Fault Circuit Interrupter) protected outlets for safety.
10 Frequently Asked Questions (FAQ) About Portable Gas Generators
Q: What is the difference between a conventional generator and an inverter generator?
A: Conventional generators make power directly, which can sometimes fluctuate. Inverter generators make DC power first, clean it up, and then turn it into AC power. Inverters produce cleaner electricity, which is safer for computers and phones.
Q: How many watts do I need to run a refrigerator?
A: A standard refrigerator needs about 600 to 800 running watts, but it needs a surge of 1,500 to 2,000 watts to start. Always check your appliance’s label.
Q: Can I run a generator in my garage?
A: Never run a gas generator inside a garage, basement, or shed. Carbon monoxide gas is deadly. Always place the generator at least 20 feet away from any door or window.
Q: How often should I change the oil?
A: Most manufacturers recommend changing the oil after the first 20 hours of use (the break-in period) and then every 50 to 100 operating hours after that.
Q: What kind of gasoline should I use?
A: Most generators run fine on regular unleaded gasoline (87 octane). Check your owner’s manual, but avoid using old or stale gas; it can clog the carburetor.
Q: What does “dual fuel” mean?
A: A dual-fuel generator can run on both gasoline and propane (LP gas). Propane stores much longer than gasoline, making dual-fuel a great choice for emergency preparedness.
Q: Is it safe to connect a generator directly to my home’s electrical panel?
A: No, this is extremely dangerous unless you install a proper transfer switch by a licensed electrician. Connecting directly can send power back onto utility lines, hurting repair workers (this is called backfeeding).
Q: How do I store a generator for the off-season?
A: Run the carburetor dry by letting the generator run until it stops, or add a fuel stabilizer to the gas tank. Store the generator in a dry, covered area.
Q: What is the purpose of a circuit breaker on a generator?
A: The circuit breaker acts like a safety switch. If you plug in too many things and try to pull too much power, the breaker trips, shutting off the power before the wires overheat or the generator is damaged.
Q: Are inverter generators more expensive than conventional ones?
A: Yes, generally they are more expensive upfront because the technology used to create clean power is more complex. However, they usually use less fuel and are much quieter.
