Disappointed by the Delock adapter () that never worked, I switched to Startech. This adapter works great and filled the office to which I had intended to say, do not have to buy cables and chargers Micro USB and Mini USB my reusing. In addition, the reverse adapter (Mini USB Male / Micro-USB female) was sent to me by mistake by the seller (Avondale) and even this adapter works fine (load and connect a Mini USB device from the Micro-USB charger made without worries). So reliable.
