Buying an external drive from EU or UK to use in USA voltage problem?

If I buy an external drive from EU or UK, can I use it in the USA or will I have some voltage problem?
Also is the Sony BDX S500U going to be sold in the USA?

You’ll need a different electrical adapter. The sockets and voltage/amperage standards in the US are not compatible with European equipment.

Haven’t seen that Sony mentioned here in the US, but it is easy to fall behind on new equipment.
