( September 2021) ( Learn how and when to remove this template message) This is a good question and one I have often thought about myself. Including an adapter in the box would be a nice addition.

There is good reason behind the 2 pin adapter, I will now explain this and I promise I won’t get too technical. Whether the battery life is worse or not as a result of this approach, I can’t say for sure, but I would be surprised. Additionally, the design allows for a more compact and less bulky design of mobile phone chargers, than the BS 1363 form factor in the UK.

Right now, aside from switching to a completely different brand of brush that can charge from the USB port in your van (Sonicare DiamondClean/DiamondClean Smart) you have no other option. However, I have noticed that the shaver adapter I use for the Vitality doesn’t charge the other two. Through experiments, I have concluded that the shaver adapters sold now are 1 amp and this isn’t high enough for the Pro range of oral b toothbrushes. I have an ancient 2 amp adapter (belonging to my dad who is now 91) which does charge the Pro series toothbrushes. The 1 amp fuse is a lot shorter than my standard 3 amp and 5 amp fuses otherwise I would simply change the fuse and see if that worked.

Most electric toothbrushes bought in the UK and Europe have charging stands that work on 220-240V. So to use them in the USA, you need a power converter to allow the charging stand to accept the 110V. 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. So, technically....... if the shaver plug is based on the old BS546 plug, if I could find a round to square pin adaptor I could use that instead? I have a multi-travel adaptor bought at an airport that accepts my UK bathroom plug without problem. But I also have 2 different ones that will not accept it, but they will accept the Euro-plug.(these are the large adaptors that can be used for multiple countries by extending different pin configurations out of the body

KS: there is ONE problem that you might face, and it does not matter if you have a shaver or a toothbrush. Strictly speaking, from an Oral-B perspective, there is no option for this at this time. So you cannot charge your current electric toothbrush from a USB port within your van.Using the travel form the UK to the USA again, the ‘Step Up’ voltage converter has the 2 pin US connector on it, but actually offers up a 3 pin UK power adapter. However your toothbrush has the 2 pin adapter, so although you are travelling to the USA, you will need the 2 pin to 3 pin adapter. Why are 2 to 3 pin adapters not included with my electric toothbrush or shaver? 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.

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.
