.... Ipad chargers usually come with clip on parts for other countries use. Use it.
The outermost usb adaptor (both outermost units are one unit although they look separate) is a standard UK three pin iPad charger.
It does come apart, and although it is a 2 pin into a UK adaptor, it is not suitable for plugging into a euro socket.That’s why I said BOTH outermost units. Haven’t had anything other than a UK adaptor with the last half a dozen iPads we’ve bought - mini's, iPad Air 2 and iPad Pro so they must do special editions with UK/Euro/US adaptors just for you.
