Buying Guide – How to Choose the Best Cheap Gas Generator
Selecting the right generator involves balancing power needs budget and portability. This guide outlines the key factors to consider to ensure you choose a unit that meets your requirements effectively.
Wattage Requirements
Determine the total wattage needed by adding the starting wattage of the appliances you plan to run. Peak wattage is the maximum power the generator can provide for short bursts while running wattage is what it sustains over time.
Choose a generator with a wattage slightly higher than your total needs to avoid overloading the unit.
Fuel Type
Generators typically run on gasoline but dual fuel and tri fuel models offer propane or natural gas options. Gasoline is widely available but propane lasts longer in storage and is cleaner to burn.
If you need long-term storage options consider a dual fuel generator that can switch to propane when needed.
Runtime
Runtime depends on the fuel tank size and how much load you place on the generator. ECO mode helps extend this by adjusting engine speed to match the demand of connected appliances.
Look for a model that offers at least 8 to 10 hours of runtime at 25% load for practical emergency use.
Portability
Weight and design matter significantly if you plan to move the generator frequently. Inverter generators are often lighter and more compact than open frame models making them easier to transport.
Select a unit with wheels and handles if you need to move it often without lifting it manually.
Noise Levels
Noise is measured in decibels (dBA) at a specific distance from the unit. Inverter generators are generally quieter and produce less vibration making them better for residential areas.
Aim for a generator that operates below 60 dBA if you plan to use it near neighbors or camping sites.
Safety Features
Modern generators include low oil shutdown and overload protection to prevent damage to the engine. Carbon monoxide sensors are also critical for outdoor use to ensure dangerous fumes are detected automatically.
Always prioritize models with CO protection features to ensure safety for you and your family.
Outlet Options
Check the types of outlets included to ensure they match your needs. Standard household outlets work for most appliances while RV specific outlets allow direct connection to recreational vehicles.
Ensure the generator has enough outlets for your devices to avoid needing extension cords that can be dangerous.
Warranty
A good warranty protects your investment against manufacturing defects. Most manufacturers offer at least a one year warranty while some provide extended coverage for specific models.
Review the warranty terms carefully to ensure you are covered for parts and labor in case of failure.
How to Use and Care for Your Cheap Gas Generator
Always place the generator on a flat stable surface outdoors and away from windows or doors to prevent carbon monoxide poisoning. Ensure it is dry and protected from rain to avoid electrical hazards during operation.
Check the oil levels before every use and use fresh gasoline to prevent clogging the carburetor. Use the provided stabilizer if storing fuel for extended periods to maintain quality and engine health.
Clean the air filter regularly and inspect the spark plug to ensure efficient combustion. Follow the maintenance schedule in the manual to extend the lifespan of your generator and keep it running smoothly.
Frequently Asked Questions
Is it safe to use a generator during a power outage?
Yes but you must place it outdoors at least 20 feet away from your home to avoid carbon monoxide poisoning. Never run a generator inside a garage or basement as fumes can seep into living spaces easily.
How much does a cheap gas generator cost?
Cheap gas generators typically range from affordable entry-level models to mid-range units. The cost varies based on power output fuel type and noise levels so always check current listings for accurate pricing.
Can I use a generator to power my house?
Yes but you need a generator with sufficient wattage to handle your home's load. You should use a transfer switch to safely connect the generator to your electrical panel and avoid backfeeding into power lines.
How long can a generator run on one tank of gas?
Run time varies significantly by model and load usually ranging from 6 to 20 hours. ECO mode helps extend this time by adjusting the engine speed based on current power demand.
Do generators need special fuel?
Most generators run on regular gasoline but dual fuel models can also use propane. It is important to keep fuel fresh using stabilizers to prevent gumming in the carburetor during storage.
Is a quiet generator better?
Yes especially if you live in a residential area or plan to camp. Quieter generators produce less noise pollution making them more pleasant for neighbors and other campers nearby.
What is the difference between peak and running wattage?
Peak wattage is the maximum power the generator can deliver for short bursts while starting appliances. Running wattage is the sustained power it provides to keep appliances operating continuously.
Can I use an extension cord with my generator?
You can use heavy-duty outdoor extension cords rated for the power load. Ensure the cord is in good condition and rated for the generator's output to prevent overheating or electrical fires.
Final Thoughts on Choosing the Best Cheap Gas Generator
We have explored a diverse range of generators from ultra-lightweight inverter models to powerful dual fuel units. The Oxseryn models offer excellent value for most users while the Westinghouse options provide heavy-duty home backup capabilities.
