The Galaxy Watch5 Charging Cradle is now available in the USA. $24.99 from Shop app. I ordered one that should arrive on the 30th. I will report on it when I get it.
I received my charging cradle yesterday. It is plastic, but it is weighted decently. It requires the charging puck from a Galaxy Watch5 or Galaxy Watch4. There are 2 inserts that fit the charging puck. If your puck is for the Watch5 one insert is smaller and fits that. The other insert fits the Watch4 puck. I used my Watch4 puck since it charges slower for better overnight charging. It is more convenient for charging with the D buckle sport band. Since I used points to lower the price it was worth it. I'm not sure about value at full price, since it is plastic and requires a charging puck to use it. Bottom line, I'm satisfied.
