Use what you already have The matching cables are often already available, but with the wrong plug combination. With this adapter, you can convert the mini-USB-B interface of your USB device into a micro-USB-B socket. This means that you can also use the micro-USB-B data/charging cable usually supplied with your smartphone/tablet for external hard drives or video cameras, for example. This is good for the environment and your wallet. Gold is the trump card The gold-plated plug contacts protect against corrosion and also increase conductivity. This ensures fast and long-lasting transmission of your data.
