What is a USB Cable?

USB(Universal Serial Bus), was been developed in the 1990s, simplifiying the connection between computers and peripheral devices. It was widely used for data transmission like connecting computers with mobile devices to transmit files such as video, songs and pictures, as well as charging phones and external connections.


Different Types of USB Cables

USB Type A

USB type A is rectangular in shape, and the most popular USB cable nowadays. It is usually seen in DC, media players and smart phone charging cables.

USB Type B

Type-B connectors, at the other side of USB cable, plug into a peripheral device like hard drive and smart phone. The types of Type-B socket can be divided into standard, mini and micro. They all have same function but different socket shape design as for plugging together in the way they work.

USB Type C

Type C allows for reverse plug orientation, which means that you can plug in your USB cable correctly whether in positive or negative direction without worrying about being upside down.

The Importance of Choosing a Durable and High-Quality USB Cable

USB chargers impact how fast your device's battery will be fully charged. Choose the right USB cable for your smart phone is of great important for a safe and quick charge experience. It may bring many potential safety risks to you if you choose a cheap USB cable. The main problem of charging safety is that the interface plug is not durable and will be broken due to plugging with many times after long time use. It may lead to prolonged charging time, unstable data transmission, fracture and other hidden dangers, or even lead to electronic equipment scrap or explosion.

So, it is really important for you to choose a high-quality USB cable. The following will tell you the influence factors and tips to choose a durable USB cable.

Influence Factors of USB Cable’s Performance

Cable Material

There are many different materials being used in USB cables in the market. They are different in wire materials, design, specifications and other aspects. Some commonly used are PVC, TPE, Nylon, metal weaving, and mercerized cotton.

  • PVC material is a common material used for most USB cables. It has non-flammability, high strength, weather resistance and excellent geometric stability. However, it was abandoned by the appearance of better performance of TPE outer coating material.
  • TPE is plastics which has good elasticity and toughness. It is environmentally friendly because the waste TPE materials can be recycled. At present, most of the original USB cables of smart phones still use TPE material.
  • Nylon braided is a special fabric material added to the original USB cable to enhance the external tension of the USB cable and ensure that the copper core inside the mobile phone cable is not damaged due to external tension. Nylon braided USB cable is not easy to be torn off. It is very strong, firm and exquisite in appearance.

Zendure designs its own super durable USB cable with defense-grade material. It has passed 50,000+ bend test to prove its super durable performance. SuperCord USB cable is your best choice for a durable charging cord.

The Length of USB Cable

Data transmission and charge speed of smart phone USB cable is related to the length of data cable. In the case of the same material, the shorter the length of data cable, the faster the data transmission and charging speed for the smaller the resistance.

The Thickness of USB Cable

The wire of the USB cable will affect charging speed. The unit of the wire is AWG. The thicker the wire, the greater the load flow, and the faster the charge will be. However, the cable also needs to have a metal braided mesh to ensure the magnetic interference shielding effect, which will enhance the cable's tensile strength.

Tips on Choosing a Durable USB Cable


Touch the USB cable to identify if it is soft or hard. A little softer the cable, the better quality because the cheap cable usually has the hard touch feeling. And the soft cable help with easy storage.


Look at the package detail and the cable extension carefully. The thicker the wire is, the higher its tensile strength is, and the larger the power output is. The cable wire body is not easy to get hot, and the thick wire body has a good protective effect on the inner copper core. As for this perspective, we highly recommend Zendure super durable USB cable because of its advanced materials and construction.

Inner Core

A good USB cable adopts a thick, high quality copper core. The resistance of pure copper core is small, which can improve the efficiency of data wire charging. The charging is efficient and stable.

However, the inner core cannot be directly identified with the naked eye, so we can choose the data cable with thick wire diameter, heavy weight and relatively hard wire while choosing.

Cable Connection

Better quality cables connection are exquisitely made, compact and durable, and the insulation layer is soft and tightly coupled with the wire harness. It is easy to identify with cheap one which is not neat and well-made.

Zendure USB cable premium design and high-speed charging performance can be the best reason why you should choose it as your work and household essential.
