Braun kitchen appliances are generally designed for specific voltage ranges based on the market in which they are sold. In Canada, Braun devices typically operate on 120 volts. Using these appliances with international voltage, such as 220-240 volts, without a proper voltage converter can lead to damage or malfunction. Each appliance may have different specifications, so it is essential for users to refer to the user manual or product specifications for detailed information. Some Braun appliances may be dual voltage, allowing them to adapt to different voltages, but this is not common for all models. It is advisable to visit the relevant section of the current Braun website for information specific to each product, including safety tips regarding voltage compatibility.
