Buying Guide – How to Choose the Best Cheap Gas Generator
Choosing the right generator requires balancing power needs with budget and portability. Here are key factors to consider before you buy.
Power Output Requirements
Determine your wattage needs by listing essential appliances like refrigerators and lights. Peak watts indicate starting power while running watts sustain continuous operation.
Always choose a model with a peak wattage higher than your total running watts.
Fuel Type and Runtime
Gasoline generators are common but dual fuel options allow you to use propane too. Runtime at 25 percent load is usually higher than at full load.
Check the fuel tank size to estimate how long you can run without refueling.
Portability and Weight
If you need to move the generator frequently look for lightweight models or those with wheel kits. Weights can range from 30 lbs to over 300 lbs.
Prioritize units with handles or wheels if you plan to transport it often.
Noise Levels
Noise is measured in decibels or dBA. Inverter generators are generally quieter than open frame models.
Choose a unit under 70 dBA if you plan to use it in residential or camping areas.
Inverter vs. Open Frame
Inverter generators produce clean power safe for sensitive electronics. Open frame units are often louder and less expensive but may damage laptops or phones.
Select inverter technology if you need to charge modern devices safely.
Emissions Compliance
Look for EPA and CARB compliance to ensure you can legally use the generator in your state. Some areas have strict environmental regulations.
Verify local laws before purchasing to avoid penalties or usage restrictions.
Safety Features
Safety features like CO alert technology and low oil shutdown protect you and your machine. Overload protection also helps prevent damage to connected appliances.
Always prioritize models with built-in safety systems for peace of mind.
Warranty and Support
A good warranty like 2 years or more indicates manufacturer confidence. Check if the brand offers customer service and parts availability.
Longer warranties can save money on potential repairs down the line.
How to Use and Care for Your Cheap Gas Generator
Always start the generator outdoors in a well-ventilated area to avoid carbon monoxide poisoning. Ensure the unit is on a flat and dry surface before use.
Perform regular maintenance by checking oil levels before every use and changing the oil periodically. Clean the air filter as recommended by the manufacturer.
Store the generator in a cool dry place and consider using a stabilizer if storing fuel for long periods. This ensures reliability when you need it most.
Frequently Asked Questions
What size generator do I need for home backup?
You typically need between 5000 and 7500 watts to power essential appliances like a fridge and lights. A 10000 watt unit can power more heavy loads like an air conditioner.
Are inverter generators better than standard ones?
Yes inverter generators are quieter and produce cleaner power safe for sensitive electronics. They also offer better fuel efficiency due to variable engine speeds.
How long does a gas generator last on a tank of fuel?
Most portable generators run for 6 to 12 hours on a full tank at half load. Larger tanks and lower power consumption extend this runtime significantly.
Can I connect a generator to my home directly?
You should never plug a generator directly into a wall outlet without a transfer switch. Use a transfer switch to prevent back-feeding which is dangerous for utility workers.
Do cheap generators need oil changes?
Yes almost all gas generators require regular oil changes to prevent engine damage. Follow the manual for intervals usually after the first 5 to 10 hours.
Can I use a generator in the rain?
No you should never run a generator in the rain or snow. Keep it under a canopy or shelter but ensure adequate airflow to prevent overheating.
