Your link does not work for me. But I think you are referring to the product with the manufacturer's number EP-PG950 (http://digit.ec/6200033).

In a nutshell:
The linked charging station (EP-PG950) was released to coincide with the release of the Galaxy S8. This charging station (EP-N5100TBEGWW) was recently launched with the Galaxy S9 and is therefore newer. However, both products are compatible with all Qi-certified smartphones. In the case of the Galaxy series, this means from the S6 onwards.
