USB Connector Guide | Guide to USB Cables

WIf you purchased your first computer about 15-20 years ago, you would surely be proud to present a 1GB hard drive. This could also be surpassed a few years later with up to 10 or 20 GB. If you think about it today, you will surely also have to smile that these giants of hard drives are now not only replaced by USB sticks but also surpassed. Your smart or i-phone already has more storage space than the huge “monster” of PC from that time. In principle, everything is controlled, charged and connected today either via USB cable or HDMI cable. Hardly any consumer electronics device, which works wirelessly, is charged with another plug. Since there are so many devices with a USB port, there are also correspondingly many USB cables. The PC alone, which used to have 1 – 2 USB hub in the best case, now has up to 5 or even six extra USB hub ports, except for those that have to be connected to the desktop, keyboard, mouse, etc., which already go up to generation 3.1. Now you also need the new USB cable, because the old generation no longer works flawlessly or not at all on the new connectors. The development is progressing faster and faster; you must not stop there yourself. Otherwise, you have literally missed the connection.

Smartphones, iPhones, tablets and the like – all are charged via USB cable or can be used to establish a direct data connection to another compatible device. A well-known smartphone manufacturer has started not to assign a new charging cable to every new phone. In this manufacturer model, you can charge a 1st generation mobile phone with the same USB cable as the 5th or 8th generation. This has significant advantages. But there, too, there are small but insignificant deviations that can be used but do not have to be. Some models can be connected to the PC with a so-called quick charging cable or with the conventional mini USB cable or can be charged with a suitable plug for the socket. Luckily, the manufacturers, no matter which smart or i-phone come over them, supply the appropriate USB cable at the time of purchase. If this is not the case, then it is recommended to look at the contact port on the device or to read in the operating instructions which USB cable is the right one. Accordingly, you can start your selection.


But what is actually a USB cable?

Das USB (Universal Serial Bus) Cable, was released to the public market around 1996 and wa

USB cable

s originally intended to be used only for connecting external devices to the computer to improve the connection quality. Thanks to its many years of further development, it now serves to connect two suitable devices. For example, it can connect a mobile phone and a PC and exchange data, as well as two smartphones for playing an app together. To do this, you need a USB cable with a normal and a mini-connector on both sides. Devices that are to be connected within the PC usually have two identical connections. For PCs that require more USB interfaces, there is a so-called USB hub or plug-in modules, which are easily mounted into the PC, such as a graphics or sound card element. This expands the connection capacity for several additional USB cables without causing a loss of computer quality. If the distance from one device to another to be connected to each other is too far, extensions can be plugged between the device and the USB cable. Example:

You cannot side by side with your printer or scanner (or a device that integrates both), but you must bridge a distance of about 6 meters. This is an extension. Meanwhile, you can also buy USB cables at this length. Over time, the appearance of the connectors of the USB cables has not changed significantly. The basic shape has remained, only small, flatter or rounded plug modules have been added.

A small list of modified and renewed types will make this clear to you:

  • The LOW POWERED PORT has been distributed with the designation USB 0(cable or stick)
    • 5 volts, too Voltage is around 4.40 – 5.50 volts, maximum current = 0.1 A, maximum power = 0.5 watts
  • The HIGH POWERED PORT has the designation USB 0(cable or stick) and can still be found on some computers today.
    • 5 volts, too Voltage is 4.75 – 5.50 volts, maximum current = 0.5 A, maximum power = 2.5 watts
  • The USB 0 and 3.1 are among the newer connectors for a cable and a stick.
    • 5 volts, too Voltage is 4.45 – 5.50 volts, maximum current = 0.9 A, maximum power = 4.5 watts
  • The UNIVERSAL BATTERY CHARGING USB – BC 1.2 for one cable.
    • 5 volts, too Voltage is 4.45 – 5.50 volts, maximum current = 1.5 A, maximum power = 7.5 watts
  • The USB Type C for cables or sticks.
    • 5 volts, too Voltage is 4.45 – 5.50 volts, maximum current = 3 A, maximum power = 15 watts
  • The UNIVERSAL POWER DELIVERY USB connector for a cable
    • 5, 12 or 20 volts, maximum current = 5 A, maximum power = 100 watts

  1. They have something in common: they have a mains voltage of 5 volts, except for the Universal Power Delivery, which can handle a power voltage of both 5 V and 12 V or 20 V via a USB cable or USB stick. USB cables and sticks are absolutely on the rise and will safely replace many of the conventional power supplies on technical devices in the near future. The reasons for this are obvious: The transmission of data is transmitted at a much higher speed, which is about 10 Gbps.
  2. Faster recommissioning of tablets, mobile phones, laptops and the like is ensured, as the shorter battery charging time (up to 100 W and 3 A) no longer results in long waiting times in order to be able to make calls or send e-mails.
  3. Not only the HDMI cable but also a good USB cable can ensure that your sound and image quality is at a 4K – Ultra HD resolution when used correctly.

And, these are just three reasons why the innovation of power supply and data transmission for technical devices is called USB cable. But here, too, there are small pitfalls. You can’t look into a USB cable, and you don’t know if it’s a fake offer or a real price crunch. Externally, they are indistinguishable, and manufacturers of cheap copies also make use of this. It is really very difficult for the consumer to distinguish between them. Above all, many of these copies are circulating on the Internet. You may think that you are making a real bargain, which may be the case, while you run the risk of going to a deeper with his “cheap scrap”. And not only that. For example, if you purchase a USB-C cable that is not certified, at least by which the certification is not visible at first glance (it should be), then it can happen that if you still buy it and still use it – your device to which you have connected it:

  • or may have an immense, perhaps irreparable defect
  • the USB cable can break or is easily loaded
  • the plug of the USB cable can become unstable, interfere with the transmission or completely abandon the mind, in the worst case even cancel and damage your device in such a way that repair is no longer possible (also the warranty services are no longer necessary in this matter)
  • Your connected device runs uncleanly, does not charge properly or fails completely

In the end, you don’t save money at all – it’s the opposite! For example, how do you recognize an original USB-C cable?

  • Each USB cable (also a USB-C cable) has a certificate symbol and emblem and a logo of the manufacturer, which can be seen on the first glance on the packaging and/or on the product, was printed straight and not in the skewed form
  • Typing errors, implausible or confusing translations also indicate a copy of the real, well-known USB-C cable
  • If the USB-C cable is offered far too cheaply, then don’t make a bargain!
  • Much more you will fall victim to a fake or the USB-C cable is cheaply processed, so you won’t have much fun with it for long.
