They might say they can
use each voltage but unless it's a welder or the like that can sense the incoming power, you change the wiring like you would do on a 115/230v motor found on many stationary shop tools.
110 volts is ancient in this country. We were 115 average at one time but David is correct that 120+ is the standard today. Here it's 123v.
