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 a risk and the warranty may be voided. Also, service for the US version TM5 might not be available in the non-US country.
