Some electric toothbrushes have charging stands that will support 110-240V meaning you will not need the voltage converter. The Philips Sonicare DiamondClean is one example.

Bathrooms are deivided into designated zones, 0, 1, 2 and regulations cover what type of light, heater other appliances can or cannot be installed in the different zones. What you may need though is a plug adapter. This is to convert the 2 pin adapter found on most charging stands in the UK and Europe to work with the power supply in the other country. To be honest, I would have done the same thing. Aside from the 2 pin AUS power connector, the UK voltage is very similar and will have likely been supported by your charging stand. You are best powering or charging each device independently as and when you need it. For example, connect and charge your toothbrush, when that is done, connect and charge your shaver or other appliance. Your commentsIt is very detailed and legally correct description of why we have 2 pin plugs on electric toothbrushes. This is a good question and one I have often thought about myself. Including an adapter in the box would be a nice addition. KS: there is ONE problem that you might face, and it does not matter if you have a shaver or a toothbrush. For example, let’s say you live in the UK and are going to the USA and assuming you are going long enough that you need to charge your brush when there. Please note: This information relates to the UK and Europe primarily, America and many other countries differ.

There is good reason behind the 2 pin adapter, I will now explain this and I promise I won’t get too technical. Under most circumstances if you include water and electricity the effects of injury are much greater as water reduces the resistance the human body has to the electrical current.

I really hope all of the above is helpful to you and has answered any questions you may have had about 2 pin plugs and adapters required for electric toothbrushes and similar products like shavers. Buying more adapters will add to environmental problems caused by the prolifieration of waste electrical equipment. Many homes will however, have spare three pin plugs for reuse.
