A 1300-watt generator is one that can reach an electrical output of up to 1300 watts. Their supporting current flows from essential home appliances during an outage to outdoor activities and off-grid living.
There are three main types of 1300-watt generators:
-
Portable Generators: These are traditional gasoline-powered generators that offer a compact and mobile design. They are ideal for outdoor activities, construction sites, and emergency power needs.
-
Inverter Generators: Inverter generators are more advanced and efficient than traditional generators. They use an inverter to produce clean, stable power suitable for sensitive electronics like computers and televisions.
-
Solar Generators: Solar generators are environmentally friendly and operate by converting solar energy into electrical power. They are often paired with rechargeable lithium-ion batteries for energy storage and can be an excellent choice for off-grid living or camping.
When discussing generator capabilities, it's essential to understand the following key terms:
-
Starting Wattage: This refers to the initial surge of power required to start an appliance or device. It is typically higher than the running wattage.
-
Running Wattage: This is the continuous power required to keep an appliance or device operational after it has started.
-
Surge Wattage: Also known as peak wattage, surge wattage refers to the maximum power output a generator can provide for a short period, typically a few seconds.
-
Watt-Hour (Wh): This unit measures the energy capacity of a generator or battery. It represents the amount of energy that can be supplied over one hour at a constant rate of one watt.
Understanding these terms will help you determine the appropriate generator size and runtime for your specific needs.
What Size Generator Do I Need?
To determine the appropriate generator size for your needs, follow these steps:
-
List all appliances and devices you plan to run simultaneously on the generator. This could include lights, refrigerator, TV, computer, tools, and more.
-
Find the wattage rating for each item on the appliance label or in the owner's manual. If you can't find the wattage, you can calculate it by multiplying the voltage (usually 120V) by the amperage.
-
Identify the surge wattage for appliances with motors, such as refrigerators, freezers, and air conditioners. The surge wattage is the extra power required to start these devices.
-
Add up the running wattages of all the items you want to run at the same time. This will give you the total running wattage requirement.
-
Calculate the surge wattage requirement by adding the highest surge wattage from your list to the total running wattage.
-
Choose a generator with a rated wattage that exceeds your calculated surge wattage requirement. It's generally recommended to have a 20% buffer above your calculated needs to account for future expansion or additional loads.
Remember, a number of high-watt appliances put on at the same time will be requiring a larger generator. Always go through the recommendations of a manufacturer and prioritize essential needs while choosing the size of the generator.
What Can a 1300-Watt Generator Run?

How Many Amps Does a 1300-Watt Generator Put Out?
To calculate the amps a 1300-watt generator can put out, you need to know the voltage. Most generators produce 120V or 240V AC power.
For a 120V generator, use this formula:
Amps = Watts / Volts
Amps = 1300 Watts / 120 Volts
Amps = 10.83
So a 1300-watt, 120V generator can provide up to 10.83 amps of current.
For a 240V generator:
Amps = 1300 Watts / 240 Volts
Amps = 5.42
Therefore, a 1300-watt, 240V generator can supply up to 5.42 amps.
Note that these calculations are all made based on the assumption that you are drawing upon the generator's full capacity of 1300 watts. You said you are actually using 650 watts. That would make the computed amperages half of what I have described here.
Always take the actual voltage and current ratings from the generator specifications and manuals. This way, however, you can estimate amps for any given wattage.
What is the Quietest 1300 Watt Generator?
When it comes to picking the quietest 1300-watt generator, it is a good thing to know different types of generators and what sound levels are attached to them. A variety of factors determines how noisy a particular model is, and the main ones involve design and technology used.
Inverter Generators
These generators are designed to be very quiet, making them ideal for areas that require no noise or low levels of noise. Advanced alternators and electronics in these generators provide clean power output with extremely low noise levels. Inverter generators run at about 50-60 decibels, which is the equivalent of a normal conversation.
Conventional Generators
They are sometimes called open-frame generators. Overall, conventional generators are normally noisier compared to inverter generators. They use the more traditional alternators and noisy engines. Their noise could be 70-80 dB or even much more with different models and loads.
Enclosed Generators
Some manufacturers offer what is called an enclosed generator, which serves as a means for reducing the levels of noise. In such units, the engine and alternator are completely enclosed in a sound-dampening enclosure or housing. Enclosed generators are not quite as quiet as inverter generators but can considerably reduce the noise level compared to open-frame models, usually operating in the range of about 60-70 dB.
Inverter generators are often the best options among the quietest 1300-watt generators. It is similarly essential to consider that such a category, and with close groups, there is some difference in noise between different models and brands. A few of the factors that may cause this difference in overall noise output include engine size, muffler design, and insulation material.
It is always good to consult manufacturer specifications and user reviews to get an actual idea of noise level generation from a particular generator. Whereas in practice, it would be good to remember that intended usages and environments differ, and a noise level acceptable in some settings may be too loud in others.
How Long Does a 1300-Watt Generator Last?
The runtime of a 1300-watt generator is ruled by three parameters: fuel tank capacity, load demand, and the rate of fuel consumption. A deeper explanation of each of these will let you approximate how long your generator will run before the need for refueling arises.
Factors Affecting Runtime
Fuel Tank Capacity: Generators with larger fuel tanks can run for more extended periods without refueling. Most 1300-watt generators have fuel tank capacities ranging from 1 to 4 gallons.
Load Demand: The more electrical appliances or devices you connect to your generator, the higher the load demand will be. Higher loads drain the fuel faster, reducing the runtime.
Fuel Consumption Rate: This rate varies among generator models and depends on factors like engine efficiency and load demand. Generally, the higher the load, the higher the fuel consumption rate.
Calculation Example
To estimate the runtime of your 1300-watt generator, you'll need to know the fuel tank capacity and the generator's fuel consumption rate at different loads.
Let's assume your generator has a 2-gallon fuel tank and consumes 0.2 gallons per hour at a 50% load (650 watts). Here's how you can calculate the runtime:
-
Determine the fuel consumption rate:
- At 50% load (650 watts), the fuel consumption rate is 0.2 gallons per hour.
-
Calculate the runtime:
- Runtime (hours) = Fuel Tank Capacity (gallons) / Fuel Consumption Rate (gallons per hour)
- Runtime = 2 gallons / 0.2 gallons per hour
- Runtime = 10 hours
That means, with a 2-gallon fuel tank and operating load of 50%, the runtime of your 1300-watt generator would be approximately 10 hours before refueling again.
Note that this is an approximate calculation, and the actual running time will depend on several factors such as weather temperature, altitude, and age of the generator. It's always a good idea to keep tabs on your fuel level in the generator and have a backup plan should you need to refuel or switch to an alternative power source.
FAQs
What is the difference between starting watts and running watts?
The surge watts, also referred to as starting watts or peak watts, are the burst of watts that most appliances and tools with an electric motor, such as refrigerators or air conditionors, would require to start. Running watts, on the other hand, are continuous watts an appliance would require to keep it running after it has started. Since these starting watts are usually greater in value than the running watts, there is a need to take into account both the starting and running watts when making a choice of a generator.
Can I run my entire house on a 1300-watt generator?
No, a 1300-watt generator would not be strong enough to keep an entire household running at one time. In their building, these generators were designed for simple appliances and tools but couldn't bear the combined load of several high-watt devices such as air conditioners, ovens, and electric heaters. You would need a much bigger, typically in the range of 5,000 to 10,000 watts or more, to power an entire house.
How do I calculate the wattage I need for my appliances?
To determine how many watts your appliance will require, first you will need to check the appliance manufacturer's rating of the appliance or in the owner's manual. Most appliances will have this rating in either watts or amps. If the rating is listed in amps then you multiply the number of amps by the voltage, which is usually 120 volts in most household appliances. Add together the wattages of all the things you will be running in your house at the same time, and purchase a generator that has a rated output at least as high as the total amount.
Can I run a 1300-watt generator indoors?
No, do not operate gasoline-powered generators indoors, even in such allegedly safe locations as garages or basements, with open windows or doors. Generators produce carbon monoxide, an odorless, colorless, and potentially deadly gas. Always operate generators outdoors in well-ventilated areas away from windows, doors, and vents.
How often do I need to refuel a 1300-watt generator?
Refueling frequency is based on the fuel tank capacity of the particular generator and the load you use. Most 1300-watt generators have fuel tanks that fall within an average range of 1 to 2 gallons. In regular use, refueling will be required after every 4 to 8 hours of continuous running at a typical load. You should be able to keep track of the fuel level in the tank and only refuel when it's not bone dry to avoid causing damage to the generator.
