Have you ever tried to transfer files from your computer to your phone using a Data cable, only to have your computer refuse to recognize your phone? — It merely charges the device.
Well, It's not a big deal, and I suppose we've all experienced it.
To what end do these things occur, though? In some cases, the data cable may be a counterfeit. It is also possible that your cable is damaged or malfunctioning in some way. Yet, in most cases, your USB cable is good; it was simply not designed to carry data.
So, what's the difference between a data cable and a charging line? Keep reading this article to become familiar with chosing a USB cable for data transfer.
You might have been persuaded to assume that all USB cords can transfer data since most of the ones offered with smartphones and those that arrive with them can. On the other hand, they don't.
The two most common kind of cables are Data cables and charging lines. Charging lines can only be used to charge your phone or other electronic gadget. Information cannot be transferred from one gadget to another. In common parlance, these cables are known as "charge-only" cables. In contrast, data cables can be used to both power and transfer data between electronic devices.
The construction of a data cable is different from that of a charge-only USB cable. In particular, the nature of their wiring or the number of conductors within the cable is different. Even though the exterior of your USB cords is attractive, there must be wires inside. The ability of a cable to charge your phone, transfer data, or do both depends on the number of wires it has.
In most cases, there are four wires in a data cable (positive, negative, data transfer & data receive). The positive (+) and negative (-) lines supply electricity to the device. Information is transmitted and received on the "data transfer" (D+) and "data receive" (D-) wires, respectively. In contrast, charging lines are only equipped with the power wires (positive and negative) and not the wires for data transfer.
Because of their critical nature, all USB cables include a positive and negative wire. Not all USB cables, however, feature the data-transfer pins. Because of this, there are cables that will solely charge your phone.
It is nearly impossible to discern charge-only cables different from data-transfer connections because the USB Implementers Forum does not require manufacturers to do so. Yet, there are some tried-and-true methods for determining whether a USB connection is limited to charging solely or can also transfer data.
As they contain more wires, USB data cables tend to be bulkier than USB charging cables. The outer insulation of data cables is thicker than that of charge-only cables because data cables have four wires rather than two.
To be sure a USB cable you intend to buy online supports data transfer before you buy it, you should call the store's customer care. If you're purchasing the cable from a physical location, check with an employee to ensure that it is indeed a data cable.
In addition to determining whether or not the cable is a data transfer or charging cable, you can also test it (s). In the absence of a standardized label, symbol, or icon from the USB Implementers Forum, you'll need to test each cables to determine their specific characteristics.
The USB cable is probably not a data-transfer USB cable if you are unable to access your device on the computer and the phone just charges.
