Will I need a voltage converter for my UK electrical items in China?

Natasha, you may check and see what the voltage range for your electrical items. According to what I know, the standard voltage in UK is 230V. In China, it is 220V. In fact, the voltage different is very little. You may ignore it. By the way, if the voltage ranage for your items is from 110V to 240V, you won't have a problem to use them in China.

However, you'd better bring an adapter because the socket in China is different.
