SCOSCHE BLMDWT-XTSP BaseLynx Vert Modular Charging Station for PD 3.0, USB-C and USB-A Devices

I have the end cap with usb+usb-c, apple watch, wireless charge, and the verticle charger with 2 usb+usb-c. Is it possible to add one more vert charge

Hi, when will this item be in stock?

Can i use it in eu 230volt ac outlet?

I am interested in the watch and phone chargers. . Is it necessary to buy a separate end cap charger too?
