Best Generator for Emergency Preparedness: Comparisons Guide

SHTFPreparedness may collect a share of sales or other compensation from the links on this page.

When disasters strike, often one of the first services to be disrupted is electricity. We rely on electricity so much in our day-to-day lives these days that not having electricity for even a short period of time will be challenging for most households.

Having a good generator will definitely aid in being prepared for an emergency. A generator will allow you to run certain essential electrical items until the normal power supply is restored.

There are a number of considerations that need to be taken into account when you are purchasing a generator. One of the biggest factors in considering what you would like the generator to run is in terms of your electrical appliances.

You need to calculate the total load you would need the generator to handle in order to get the generator with the correct capacity. It is important to remember that certain electrical items will draw too much power for most household generators to handle.

Many electrical appliances are used for heating, like a stove or microwave, and these items generally draw too much power for an average generator to handle.

For these types of heating appliances, it could be useful to get an emergency gas stove instead. Have a look at our article, 5 ways to heat your home for free to get some more heating ideas.

Another important consideration when selecting a generator for emergency preparedness is the type of generator and how it is powered. Some generators use gas to generate power. Some use an inverter and batteries to generate power. Some are solar-powered.

It is important to consider how the power is generated to know if you will be able to maintain the generator and for how long it can be used before needing to be replenished in the form of more gas, etc.

With these and other considerations in mind, it can be overwhelming to choose the best generator for emergency preparedness but we have a great list to help you make the best decision for your needs.
