Well, the nature of my job as an IT Specialist and a Researcher, takes me from place to place every now and then and in most of my journey I come across folks complaining about how USB cables don't seem to work like those ones that were first shipped into Nigeria when the rave of smart devices just hit this region of the world. This has always given me reasons for concern most especially since, family and friends are amongst those whom are not considered as "Tech-Heads" and considering also the fact that fake USB cables and chargers can spoil/destroy your device battery and in some cases, your entire device thus, I got prompted to pen this down so as to create, at least, a reasonable sense of awareness.
There is a certain feature that one can look out for when buying one of these USB cables if one expects to get the best value for your money and/or make your battery life and device last longer for maximum utility.
When buying one of these USB cables from any tech store, you should look out for the colour of the metallic in between the two openings at the tip of the USB cable that goes into the charger. If the cable (or wire, depending on the one you understand the most) is not golden in colour but silver then, it's not an original one. This is because, copper that conducts the electricity between your power source and your device is usually golden in colour, not silver, does enabling proper conductivity of electric voltage. The ones with silver colour cable in between the two slots are made from aluminium and this is a poor conductor of electricity when compared to copper. This is as depicted in the picture shown below. Now, I believe you have the perfect check on which is, and is not, an original USB cable.
