When a storm strikes and the power goes out, a generator from one of the best generator brands 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. In this guide, we delve into the world of generators—both portable and stand-by systems—to identify the best brands in the business. We leveraged our own experience using generators as a backup source of power for home and RV, along with extensive research to inform our selections of the best generator brands.
1. Honda
Price Range: $$ to $$$$
Our Top Picks: Honda 2,200-Watt Portable Inverter Generator for $999 and Honda 1,000-Watt Portable Inverter Generator for $999.
Not only is it a manufacturer of some of the most reliable automobiles on the market, but Honda also produces some of the best generators available. 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 EU2200i produces around the same amount of noise as a coffeemaker at its loudest (between 48 and 57 decibels).
