Xbox series S bought from Amazon Germany

Yes, you will be able to play it when it arrives. The Xbox Series S is similar to the Xbox One, in that it supports multi voltage, so just change the power cable to an American one, and you should be good to go.

Yes that is correct!

I bought the console from amazon in germany with a pre installed 250GB hard drive

There is no such thing as a series one S, do you have a one S or a series S? If it has a disc Drive it's a one S

If you purchase the Xbox one version it will work on both systems, but the series version will work on series

Unfortunately since you bought the code from a third-party retailer no refunds are available, and since you redeemed the code it's unlikely Amazon would refund you because they can't take it back

The Series version is playable on the cloud via GamePass Ultimate

Xbox s I bought the game from Amazon on pre order

I bought it from Amazon, I called MS this Morning and they helped me and now i got my 50 € Card.

Thanks for the help Guys Greetz from Germany
