Top 10 Best Generators (2021 Review)

Having a backup generator not only gives you peace of mind but also prepares you better for a power outage during a weather-related emergency, natural disaster, and even a pandemic. The most popular generators to buy is a portable generator because it keeps you safe at home and powers your appliances, tools, and electronic devices for RV trips, camping, and job sites.

As you shop, factors such as startup power, fuel type, tank size, runtime, noise level, and the number of outlets ultimately affects the quality, efficiency, and price of a generator.
