Cables are an inevitable part of every gadget. Whether it is something as big as television, or as small as a mobile phone, you need them to get the necessary work done quickly and efficiently. Carrying one with yourself wherever you go, or keeping one at home or work desk is always a good idea, as it comes handy in a variety of ways. This is the most popular one out of the lot. The primary function of these cables is the fact that they can help transfer files at high speed, while also charging your phone. Make sure the size of the port supports your mobile phone’s port and fits appropriately. The cable used to connect a smartphone or a tablet to another device, which has a micro USB for charging, is called a power-sharing cable. This just means that both the devices share the power. Listening to music will be a piece of cake with an AUX cable at your disposal. All you have to do is connect it to a stereo’s input, and enjoy listening to music or watching a movie.
