The Best Generator Brands of 2021
Finding the right generator for your home, RV, or job site begins with selecting a reputable brand.
When a storm strikes and the power goes out, a good generator can prevent hours in the dark and a fridge full of spoiled food. Depending on its size, a portable generator can provide up to 15,000 watts of energy, enough to keep the lights on and power the air conditioner and refrigerator. However, a generator is only as good as it is reliable. With so many brands on the market, finding a model that provides dependable backup power without breaking the bank can pose a challenge. This guide delves into the world of generators to identify the top brands on the market and reviews the factors that make these generators a good purchase.
Known for: Honda’s generators have a reputation for reliability and relatively quiet operation.
Price: $1,000 to $5,000
Editors’ Choice: The Honda EU2200ITAG 2200-Watt 120-Volt inverter (available on Amazon) offers Honda’s reliability and ultra-quiet operation, as well as handy safety features and smart capabilities.
Not only does the brand manufacturer some of the most reliable automobiles on the market, but it also produces quality generators. Honda revolutionized the generator market when it introduced the now legendary EU1000i model in 1998, redefining the market for portable power.
Since then, the company has continued to improve on that technology while others have sought to copy it. Though this generator is more expensive than others, consumers are willing to shell out the extra dough because of Honda’s reliability and reputation for quiet operation—the EU2200ITAG produces around the same amount of noise as a coffeemaker at its loudest. However, Honda’s cutting-edge technology isn’t cheap.
