Portable Generators and Power Supplies Outdoors

These generators, sometimes called backup generators, are used to provide temporary power when and where it is needed. Portable is a relative term; some are more portable than others. While the smallest models can be picked up and carried, most have wheels and a handle to make transport easier.

Giant generators are used in large buildings for backup electricity; these are larger versions of the portable ones used by homeowners and outdoors enthusiasts. The best portable generators, and fuel to run them, often are in demand after natural disasters. Generac's 5735 GP17500E portable generator is the best overall portable generator available.

When you're in a lurch with no electricity for your home or camp, having a portable generator to get things running is a godsend. These powerful machines are lifesavers after storms knock off electricity, or if you need a boost to run equipment. Ever been at your hunting or fishing camp and need to do some work?

Some examples of devices I used with large starting and running loads include a large air conditioner and a portable table saw. I evaluated these generators based on ease of starting, power response, sound levels, value, safety, and reliability to select the top performers.

Most portable generators are powered by gasoline, which is the most commonly available fuel. However, when using generators for emergency power, their infrequent use presents some issues to consider.

A portable generator is an engine running on gas or diesel fuel that creates temporary electrical power. The engine turns a small internal alternator that creates electricity. You can use a portable generator to run large items, such as a refrigerator, furnace or freezer, or smaller ones such as a microwave or television.
