Ok I should have read it better, but it really didn't occur to me that anyone today still sells electronics with micro USB instead of USB-C. A huge hassle, because all my universal cables are useless and I have to drag an archaic micro USB wire with me. Alzo, this is not supposed to be sold in the EU from 28.12.2024.
Compact
Micro USB?
