preface
As a "bridge" connecting power supplies and devices, data cables play an important role in compatibility, fast charging power, and transmission rate. In addition, a small data cable has also begun to work the appearance design to meet the needs of different consumers with as many functions as possible.
Because of this, high-quality woven wire affects consumers' first impression and use experience by virtue of their appearance and feel. For digital geeks, some cables also have a digital display screen, which can display real-time charging voltage, current, power and other data, so that users can intuitively understand the fast charging status of the device. Previously, the charging head network has successively disassembled five digital display fast charging data cables, let's take a look.
ACASIS Acasis
Akasis 100W screen display detection data cable
The USB PD data cable with screen display launched by Akasis comes with a 0.96-inch LCD screen, which supports 100W power transmission at the same time, it can also display parameters such as voltage and current, and understand the power consumption information of the device in real time. It is suitable for consumers who want to easily understand the power consumption status of the equipment. At the same time, the length of this cable is 2 meters, which can cope well with a variety of usage scenarios.
Through the dismantling of the charging head network, it is learned that this data cable of Akasis has a built-in Guangxin micro UM3506 SOC, the chip supports the E-Marker function, and can be used as an MCU, through the built-in ADC with the sampling resistor to collect current information, and collect bus voltage information, through the screen display. At the same time, the built-in HT7533-2 regulator chip is used to power the single-chip microcomputer, and the AW9364 LED driver is used to power the screen backlight.
This PD data cable of Akasis solves the problem of not knowing the voltage and current during fast charging, and can help consumers understand the voltage and current parameters of the current charging and understand the power consumption of the device. And through the size of the output power, it can help identify the authenticity of the charger. The data cable can be used as an entry-level USB meter, and the design idea is still very OK.

Mcdodo
McDuoduo 100W digital display fast charging data cable
This USB-C fast charging cable uses a braided cable body with a length of about 1.3 meters. The cable supports 5A high-current fast charging, USB2.0 data transmission, and 100W fast charging. Different from the traditional data cable, this data cable has a built-in LED digital display screen, which can display the charging power in real time, which is more practical than ordinary data cables.
Through the dismantling of the charging head network, it is learned that the data cable of Maiduoduo adopts a shielded wire design, and the internal injection of glue filling in the terminal shell increases the strength. The inside of the cable is shielded with aluminum foil, and Hynetek HUSB332 E-Marker chip is used for cable transmission capability marking, which meets the needs of mainstream fast charging applications.
The small board of the digital display terminal is welded to the LED digital display screen on one side, and the MCU, LDO, op amp chip and switch are welded on the other side, which is used to detect the voltage and current parameters, and calculate them for display on the digital display screen. The cable is braided and the USB-C terminals are made of zinc alloy for durability.

Maiduoduo 6A digital display fast charging data cable
This USB-A to USB-C interface fast charging data cable adopts a braided cable body, with a cable length of 1.3 meters, supports USB2.0 data transmission, supports 6A high-current fast charging, and supports 66W fast charging. The USB-C terminal of the data cable has a built-in LED digital display screen, which can display the charging power of the mobile phone in real time, which has a unique selling point.
Through the dismantling of the charging head network, it was learned that the data cable of Maiduoduo adopts a shielded cable design, the inside of the cable is shielded with aluminum foil, and the internal injection of zinc alloy terminals is filled with glue to increase strength. The USB-C terminal board is soldered to the LED digital display screen, and the other side is soldered to the MCU, and the sampling resistor and LDO are used to detect the voltage and current parameters, and calculate the display charging power, which is displayed on the digital display screen.

Maiduoduo 5A digital display fast charging data cable
This digital fast charging cable launched by Mcdodo is a braided cable, and the terminal head part is made of high-purity zinc alloy integrally, and the black wire body is dirt-resistant and durable, and it feels good at the same time. In addition to real-time observation of the charging power, the cable itself can exceed a maximum of 5A high current, and most brands of fast charging on the market can use and detect the charging power, and the actual measurement can trigger Huawei's 40W, 66W super fast charging, and VOOC fast charging. Of course, you need to match your own private fast charging head to trigger fast charging.
Through dismantling, the charging head network learned that the wire has a built-in shielding tin foil to prevent interference, and the core is doped with a tensile wire to improve the overall tensile performance. The thread is filled with hard sealant, and the outermost metal shell is made of zinc alloy, which has strong protection.

Summary of the charging head network
The digital fast charging data cable solves the problem of not knowing the voltage and current during the fast charging process, and can help consumers understand the voltage and current parameters of the current charging and understand the electricity consumption of the equipment. And through the size of the output power, it can help identify the authenticity of the charger. In addition, these cables are more cost-effective than buying expensive instruments.
The dismantling of the charging head network learned that the statistics of these wires are more than 1 meter in length design, plus many are braided wire design, and the terminal shell is made of metal, the overall sense of refinement of the product is more sufficient, and the length is enough to meet the use of normal office and other scenarios. Equipped with a digital display screen, the main function is to display the charging voltage, current and power.
