For home use or on the job, generators are a handy power tool that provide emergency electricity when there’s a power outage. But before you buy one, it’s important to understand how they work and follow all the generator safety information.

What will a 12000 watt portable generator run?

Portable generators run on gasoline, propane gas or diesel fuel and produce fumes that can be dangerous if not used properly. In fact, more people die from carbon monoxide poisoning from generators than from the disasters that cause power outages. That’s why it’s critical to place the generator outdoors on a flat surface away from the house, at least 10 ft. and never underneath awnings or canopies, carports or inside the garage. It’s also a good idea to plug in a carbon monoxide detector that monitors air near the generator and shuts off the engine if levels get too high.

Choosing the right Generator Basics starts with knowing what kind of appliances you plan to power and their starting wattages. Then look for a model that matches those requirements, as well as your expected runtime and tank size. For example, if you’ll be using the generator for long periods, a bigger tank will keep you from having to refuel as often.

The most common portable generators have two 120V outlets and a USB port, but larger models with more wattage may have 240V outlets as well. And since you’ll be using them outside, it’s best to find a model with GFCI (ground fault circuit interrupter) outlets that shut off the engine if there’s a fault.
