The US Market TM5 is 110v only. The Thermomix TM5 has not been certified, designed nor tested for use with converters. While in theory a converter may work, Thermomix US cannot recommend nor support the use of a non US TM5 in the US. If a customer chooses to use a converter with a non US TM5, customers should know there is risk and the warranty may be voided. Also, service for the US version TM5 might not be available in the non US country.
