With the rise of computers, cell phones, and tablets, it is becoming more difficult to find a USB port for your devices. If you're tired of struggling to charge your phone while still using your laptop or using a power strip, then this article is for you. In this article I'll be going over all the different types of USB cables and the physical differences between them. This will help you find a USB cable that can handle both charging and data transfer at once. There are 3 physical connector types of USB cables. They are Type A, Type B, and mini-A. Let's go over each one. Type A is the most commonly used USB cable (Figure 1). It is rectangular shaped with two flat sides and two rounded sides. It looks like a rectangle with two cut outs at the top for attaching to other devices or ports. If you look closely, you should be able to notice that there are 11 pins that go into the male side rather than just 10 pins like I mentioned earlier. This is because the pin spacing is made a little wider so that it can be more durable. If you ever need to look inside a Type-A port, the 11th pin will be a little bit larger than the other pins. The width of these pins are supposed to have been designed at 8.25 by 2.5 mm for Type A ports, 18 by 29 mm for Type B, and 11 by 18 mm for mini-A ports. Mini-A ports are just like Type A ports but they are smaller and aren't compatible with full sized USB cables (Figure 2). Mini-A ports are designed to fit in between a USB port and a device. They are also specifically designed for use with USB flash drives. Type B is the second main type of USB cable (Figure 3). It is shaped like a rectangle and has similar dimensions and number of pins as the Type A cable. The only difference between these two cables is that Type B's pins are closer together. This makes for a smaller cable, but it also makes it more durable because the pins can't bend apart as easily as Type A's pins can bend apart. You'll notice that on the Type B cable, there are 10 pins but there is an extra pin on top right next to one of them (green line). This pin is marked as VBUS and it's only on cables that support data transfer rates of 1.5 Mbits/s, 12 Mbits/s, 18 Mbits/s, and 480 Mbits/s. The reason for this is that the VBUS pin is used to supply power to the USB device. If a device needs a lot of power then a Type B cable can supply more power through the VBUS pin than a regular Type A cable can provide. There are also 2 other types of USB cables but they aren't as commonly used as the types mentioned above. eccc085e13
