One problem with portable generators is the noise that you—and your neighbors—have to put up with. You can compare decibel ratings to find quieter models, but keep in mind that there&#x27;s no industry standard, so you may be comparing apples and oranges. Standby generators are quieter, and for a stiff premium you can buy a really quiet portable generator like the 6,500-watt Honda shown here. It costs $4,500.Photo provided by Honda
