Portable generators are a versatile and practical solution for temporary power needs, whether you’re planning a camping trip, organising an outdoor event, or preparing for power outages.
They can keep your essentials running smoothly when you’re away from a fixed power source.
But understanding what you can realistically power with a portable generator is key to making the most out of it.
Read this guide to understand how portable generators work, what you can run on portable generators and how to effectively calculate your power needs to find out whether a portable generator is necessary for you.
What Is a Portable Generator?
A portable generator is a type of generator that can be used for daily operations. It converts fuel (gasoline, diesel, or propane) into electrical power and is perfect for supplying temporary power supply during outages, outdoor activities, and on construction sites. Portable generators are designed to be an easily transportable source of power.
Wattage and Capacity Explained
Before diving into what you can power with a portable generator, it’s crucial to understand two key terms: wattage and capacity.
- Wattage: This is the amount of power required to run an appliance or device. Every electrical device requires a certain wattage to operate, which can usually be found on the device itself or in its manual.
- Capacity: This refers to the power output a generator can produce, typically measured in watts or kilowatts.
Portable generators vary in size and capacity, usually ranging from about 1,000 watts to 10,000 watts. To determine what you can run on your generator, you need to add up the wattage requirements of all the devices you plan to power simultaneously.
Essential Home Appliances
During a power outage, you might prioritise keeping essential home appliances running. Here’s a look at some common household appliances and their average wattage requirements:
- Refrigerator: Typically needs about 600 watts, but requires up to 2,200 watts to start up.
- Freezer: Similar to refrigerators, freezers need about 600 watts for running and a higher startup wattage.
- Portable Heater: Depending on the model, these can require between 1,500 to 3,000 watts.
- Lights: A single light bulb might only use about 60 watts, but the total wattage adds up with more lights.
- Television: Modern TVs are quite efficient, generally consuming between 100 and 300 watts.
Kitchen Appliances
If you’re using a generator while camping or during an event, you might want to run a few kitchen appliances, such as:
- Microwave: Uses about 1,000 watts, but this can vary widely depending on the model.
- Coffee Maker: Typically requires about 800 watts.
- Electric Grill: Can consume up to 1,500 watts.
Remember, the starting wattage for these devices can be much higher, so always check the peak requirements when calculating the total load.
Charging and Electronics
Portable generators are also great for keeping your gadgets charged during power outages or when off-grid. Read on to find out the average wattage for some of these devices.
- Smartphones and Tablets: Generally require less than 10 watts when charging.
- Laptops: Usually consume around 45 to 100 watts.
- Wi-Fi Router: Typically runs on about 10 watts.
Power Tools
For those using a portable generator on a job site, power tools are likely essentials. Here’s the wattage for electric drills, circular saw and air compressor.
- Electric Drill: Requires around 600 watts.
- Circular Saw: Power usage can be around 1,200 watts.
- Air Compressor: Small models may run on about 1,000 watts, but larger ones might need up to 2,000 watts.
Calculating Total Wattage
To effectively use a portable generator, calculate the total wattage you’ll need by adding up the wattage of all devices and appliances you plan to run simultaneously.
Consider both the running wattage and the starting wattage as this is particularly important for appliances with motors that require a surge of power to start.
Important: Be aware that the wattage stated in this guide is an approximation. You must check to get accurate numbers for your own devices.
Tips for Safety and Efficiency
Using a portable generator requires careful consideration to ensure safety and efficiency:
- Do Not Overload
Running too many appliances simultaneously can overload your generator, potentially causing it to shut down or even get damaged.
- Use a Transfer Switch
For home use, connect your generator to your home’s electrical panel with a transfer switch. This is safer than powering devices by plugging them directly into the generator.
- Regular Maintenance
Keep your generator in good working condition through regular maintenance. Check the oil and filters, and run the generator periodically to ensure it’s ready for use when needed.
- Proper Ventilation
Always operate your generator outdoors, away from windows and doors, to avoid carbon monoxide poisoning.
Find Out Which Generator Best Suits Your Needs
Portable generators can be a lifeline in many situations, from home power outages to outdoor adventures. By understanding what you can power with your generator and how to calculate your power needs, you can make informed decisions about the best ways to use it.
Always prioritise safety, and plan for your energy requirements, and your generator will serve you well in keeping your essential devices and appliances running smoothly whenever and wherever you need them.
