What is the difference between this product and the Gigaset C530H? Is the base station still included here and only a charging cradle with the other one?
HX can be paired with various third-party base stations (routers), H can only be paired with Gigaset base stations.
See http://blog.gigaset.com/gigaset-hx
The base station is not included here. As far as I know, this model has a few more features (not relevant for me) than the C530H, but otherwise it is pretty much identical.
