The Best Portable Generators (Under $500) on Amazon in 2018

A generator is a blessing after a big storm or hurricane.

Power outages can last days or weeks, and while that sounds bad in writing, it feels much worse when you've lived through it. That's why demand for generators skyrockets after a storm.

A standby generator system automatically restores power to a home. These systems are permanently installed (often by a professional contractor or electrician) and they cost several thousand dollars. 

Alternatively, many gas-powered generators cost hundreds of dollars. These portable generators are useful for maintaining critical things like lighting, heating, cooling and food storage, but don't expect one to power a whole house (or even a whole room). 

Gas-powered electricity is expensive. It can also be dangerous. Gas generators need to be kept at a safe distance from a home to minimize the risk of carbon monoxide poisoning. Learn how to use a generator safely before buying one. 

Despite the risks and expenses, a portable generator is worth it for many households. Here are the best-reviewed portable generators (with 3,000 watts or more) selling for less than $500 on Amazon:
