Thanks, I did ring apple support but they didn't know. I have bought one and it does come with the 15v/3amp profile. So for anyone else with this query, now you know.I'm not familiar with the specs on the EU power supply. But I googled 15v/3a and similar devices popped up. The 61W Charger is the basic charging brick that comes with the MBP but each region has a different outlet connector. So when I'm in London or Amsterdam I could use my US brick but with a EU converter. Since the iPad uses USB this will work. If you travel to Ams or US you would need a converter. The voltage is the same because of the connector.
None of the stores have the info either.
Here is the US one.
You could use your Apple Support App and ask them since it's not listed online
