Propane portable generators are excellent not only as a backup power source, but for recreational purposes as well such as camping and tailgating.
They are available is different sizes and prices.
The size corresponds to the amount of wattage you need from your generator.
The lower watt propane portable generators will be able to operate smaller items, such as lights, TV, and a larger appliance while the more powerful ones can almost run an entire home.
Propane generators with around 5000 continuous watts will typically be able to run the essentials during a power outage.
This includes lighting, a refrigerator, and possibly a smaller air conditioner.
Getting a propane portable generator with about 20% more wattage than needed is encouraged so you have some extra power just in case.
You may realize too that there are more items that need power supply than you originally thought.
Also, starting appliances requires more wattage than running it.
If you want several appliances running simultaneously, then add up the wattage needed to start all of them.
This is how much power the propane generator will need, plus any other items you want to run.
Once you decide which items you want to run during an emergency, then add up all the wattages based on how much it will take to start each one.
This information can sometimes be found on the product tag, or in the manual.
Also, it's best to purchase a propane portable generator when you don't need it.
Many will only buy them when a power outage occurs.
Having one ahead of time will allow you to be prepared when the time comes.
You also won't have to rush your decision on which one to buy.
