On mainstream Android phones, the USB Type-C interface has gradually replaced the Micro USB interface. It is undeniable that Micro USB is still the interface with the largest number of mobile phones, mobile power, speakers, Bluetooth headsets, cameras, electronic cigarettes, and driving.  It is widely used in digital products such as recorders.  Sinodec Industrial Co., ltd. Provides all kinds of USB-C cable and Micro USB cable production, MOQ and fast delivery.

The ordinary MicroUSB 2.0 cable has 4 pins, and each pin is defined as follows, where Vbus and GND are used for power transmission, and Data + and Data- are used to transmit data.  The maximum carrying current of Micro USB in the safe range is 2A, and the charging current of some micro USB cables is 4A. Therefore, it has specially designed the Micro USB cable. The extra pins are used for excessive current to ensure safety.

There are countless Micro USB cables on the market, the quality is good or bad, and some are very slow to charge and cannot connect the phone to the computer.  So, how to choose when buying a Micro USB data cable?

First, look at the appearance, USB data cable has many materials to choose from, TPE, PVC, TPU, Nylon braided, etc. USB connectors also have many options, there are nickel-plated, iron casing, aluminum alloy, and gold-plated

The OD of USB is also different, some OD2.8mm, OD3.0, OD3.5mm ,, OD4.0 and even OD5.5mm usb cable. The length can also be customized according to customer requirements.  In addition, as some USB data cables for gifts, we also launched 2 in 1 USB cable, multi 3 in 1 usb cable and all in one multi usb cords.

The outer diameter of the usb cable cannot be directly linked to the thickness of the wire core, because some brands have thick and thin wires, while others have thin and thick wires. They are only described as a parameter and are not used as a direct judgment standard.

Testing

The quality of the charging line is good or bad, and the line resistance is an important evaluation parameter.  If the wire material is poor, the wire resistance will be large, and the loss during charging will be more.  We can roughly estimate the resistance of the wire through the voltage drop test, and we can also judge the quality of the wire. The faster the voltage drops, the more the data line

Summary

From the test results, the performance of the brand's Micro USB data cables is good, and they can perform normal power transmission and speed transmission.
