Questions about Roline USB 2.0 cable

I found an article about this on the Internet: http://michaelsonntag.net/testbericht-mobile-monolautsprecher/ It says under "Connections" that most of these speakers are charged via mini-USB (i.e. possible with this cable), some via micro-USB. Either the manual for your x-mini says what kind of connection you have for charging, or you enter the brand and type in Google or similar and search for a corresponding statement.
