All About the Charging Cables

A charging cable is used to charge a portable device like a smartphone. One side is plugged into a USB charger's socket, and the cable has a device connector on the other side (Micro USB, Mini USB, Apple dock connector, etc.).

What Makes a Good Charging Cable?

Your charging cable influences your device's speed, so even if you have the contemporary fast charger, you might still not be able to charge at the fastest speed possible.

What is the Difference Between Cables?

Externally, many cables look the same but, on the interior, the assembly is different, and many cables have a slow-only design. It all depends on the wire's ability to carry a fast speed.

The 4 Cables Inside

There are four cables on the inside of the wires. The green and white wire you will see are for data. While the black and red are 5V and transmit the power for charging. These wires determine charging speed. (A number of fast-charging protocols can even be up to 20V. The amount of power your wire can carry is determined by the magnitude of the two power wires inside. A typical cable is 28 gauge and capable of about .5A, which is the normal charge rate. A faster charger wire has huge internal wires (mostly 24 gauge) that can carry massive currents of 2A or more.

The association between the gauge and the total current is basic electric physics. A cable is limited in the amount of current it can transmit; therefore, a larger cable can carry more current. But this effect can get worse if you purchase long USB charger wires. China charging cable provider can make a good quality faster cable economically.

Want a Fast-Charging Cable?

At first, check if your device is fast charger capable (most are) and you have a charger capable of rendering a faster rate. Then watch the original cable provided with your device; some bigger phones and tablets come with fast, good-sized wires. So, test with that initially; if you don't have the original, grab a fast charger wire that is right for your device and desired length, and enjoy your wholly compatible fast-charging system.
