The only issue is whether you can plug it in and then you will need an adaptor to let you do this
People who have absolutely no knowledge f electricity are dangerous and should not try to answer questions. One day Eric will give an answer that kills someone. Power supplies of any kind need to be designed to work at specific voltages. Since laptop and phone chargers may regularly be used in different countries any good manufacturer may try to make it cover all the regions. Your charger is labelled 100 - 240 v. That means it is designed to run on any voltage between the US standard 110 V to what used to be the UK standard of 240 V. Most of Europe now uses 230 V so they can share generators across borders in times f shortage. A few use variations as in the case of Greece who quote 220 v. UK now states 230 v +- 10 %. So all you will need is a suitable plug to convert the pins on your charger to use Greek wall sockets. If your charger has the 2-pin plug it will fit anyway as they are universal. Most good electronics (Maplin etc) shops and computer shops sell travel packs to convert plugs.
If your charger is marked 100-240v any voltage between these figure will be OK, if 100/240 no not before checking the switch is in the 240 position
( reading Fred's screed you will only be charging you iphone you will not be inside the charger)
Voltage isn't a problem. Greece use 4 flavours of plug

All you need is a UK 13A plug adapter to the appropriate Greek plug. The most likely will be the type F.
Yes, this type charger can automatic adjust its voltage rate to fit any power source between 100V to 240V.
well if you use and adaptor I can't see what problems should occur. just don't plug it in like it is now (without an adaptor) or it will short.
This may be a daft question BUT
Will I be ok to use my UK Iphone charger in Greece (where the voltage is 220v) without a converter/transformer
Obviously i will need an adapter
I just wanna make sure my phone wont break!
Many Thanks
