How to Choose the Perfect One
Are you confused about the different types of generators? Ask yourself a few simple questions to determine the best type of portable generator for you.
1. How Much Power Does Your Home Need?
Those who buy portable machines often want one that can power appliances in their homes during an emergency situation, but even they still need to look at how much power they need. While a standby model, which is a type of permanent model, can operate multiple circuits and produce 20,000 watts of power, portable models produce less power. Most produce between 5,000 and 7,000 watts.
A good way to determine the size that you need is with a look at your home. Make a list of all the things you’ll need during an emergency, including lights, cell phones and appliances like your fridge and stove. You can then add up the number of watts each one needs.
2. What Fuel Source is Best?
Portable generators use either propane or natural gas. You’ll need to source the fuel necessary to run it and keep enough on hand to last until the power comes back on. Though some models use gasoline, you’ll need to use a special additive in that gas to make it work with the machine.
3. Do You Need an Electric Start?
An electric start makes it easier for you to turn on and use a generator. You can push a button on the front to start the motor instead of pulling on a cord to start the motor.
As you look at our list of the top portable models, you’ll want to keep an eye out for those that come with an included battery. Some companies make you purchase the battery that works with the electric start separately.
4. Should You Invest in a Manual Transfer Switch?
Standby generators usually come with an automatic transfer switch that you use to connect one to your circuit breaker. This automatically turns on the power to specific circuits. With a portable generator, you can purchase a manual transfer switch separately.
A manual transfer switch lets you hardwire or more permanently attach it to your home’s system. It provides instant power to any appliances operating on that circuit breaker. If you have a power failure, you can turn on the motor to provide power to appliances and other devices without running extension cords around your house.
