About DeWalt

DeWalt has certainly made a name for itself in the power tool and equipment industry since it was founded in 1922 by Raymon DeWalt.

Partnering with Stanley Black & Decker, DeWalt continues to have a strong presence within the US, even having seven different manufacturing facilities located in the country to produce their highly popular hand tools, power saws, and other specialty products.

Recently, they’ve also begun offering an extensive line of portable generators with traditional open-style designs and various output levels, some running on Honda engines.

While most of their products are ‘made in the USA,’ according to some sources, DeWalt’s portfolio of portable generators is not one of those exceptions as they are produced under license from Generac. Regardless, anyone looking for quality home or job site tools would be wise to give DeWalt’s offerings serious consideration.
