I got the charging head networkLvlianA USB-C data cable is introduced. This data cable uses a white plastic body, and the USB-C terminal uses an injection molded case.Printed on the housingLvlianlogo。MeasuredLvlianThe cable is 2 meters long, supports USB2.0 data transmission, and supports 100W charging power.
The data cable with a length of 2 meters has greater flexibility. Compared with the cable with a length of 1 meter, it can better meet the fast charging requirements of mobile phones and laptops.NextLvlianTake a look at the internal workmanship and materials for the disassembly of this 2-meter long data cable.
This data cable of Lvlian is packed in a translucent plastic bag, and the front of the package is designed with UGREEN Lvlian and the Chinese and English name of the product.
The back of the bag is printed with the address, hotline and other information of Shenzhen Lulian Technology Co., Ltd.
The package contains data cable and inspection certificate.
The data cable is a conventional white color matching cable, which is bound by two binding wires after winding several times.
The USB-C cable head shell and net tail are designed in an integrated way, and the surface is sanded, which is convenient for users to plug in and out.
The enclosure is designed with UGREEN brand and 5A words, which indicates that the wire can pass 5A high current, and the power transmission performance is naturally good.
Internal close-up of USB-C male head, not full PIN design.
The measured length of the data line of Lvlian is 2 meters.
The diameter of wire body is 4.24mm.
In addition, the measured wire weight is about 70g.
Using ChargeLAB POWER-Z KM003C, it is measured that the cable is equipped with an E-Marker chip, with power transmission capacity of 20V5A and data transmission capacity of USB 2.0.
In terms of voltage drop test, the test data results of 11 gears are shown in the table above.
The histogram is drawn. It can be clearly seen that the gear with the largest difference in pressure drop is 0.84V of 20V5A, and the gear with the lowest difference is 0.16V of 15V1A and 20V1A.
Finally, use this data cable with a charger to charge Apple MacBook Pro, and the measured charging power is 18.77V 4.64A 86.15W.
Lvlian 100W data cable disassembly
After watching the appearance and testing of the 2-meter USB-C data cable of Lvlian, we will disassemble it to see the materials and workmanship of this data cable.
First, cut the cable injection plug with a cutting machine, and spot weld the USB-C plug to the stainless steel shell.
The harness at the tail of the cable is filled and reinforced with hard glue.
Take out the filled hard glue, and wrap the copper foil with the cable shielding net.
Remove the steel sleeve, and fill the translucent rigid plastic insulation support between the small terminal PCB board and the steel sleeve.
Translucent filled plastic is wrapped with high-temperature tape for insulation.
Clean the filled plastic, and weld the connecting wire on one side of the small board.
The other side is reserved with an E-Marker chip.
The small plate is welded with red positive power core, USB2.0 data core, CC core, VCONN core and negative core.The positive power core is connected in parallel with two wires to reduce the resistance and improve the current carrying capacity.
Continue cutting to remove the plug at the other end.
Translucent filled plastic inside the steel sleeve is also wrapped with high-temperature tape for insulation.
The small terminal board and solder joints are also covered with translucent hard glue for protection.
Clean the hard glue covered by the small terminal board, and weld the connecting wire on one side.
The other side is welded with E-Marker chip.
E-Marker chip screen printing 332A is Huinengtai HUSB332A, and HUSB332A is USB Type-C electronic label chip (USB eMarker).It supports USB PD3.1 EPR extended power range and has passed the certification of USB-IF Association, TID No.: 4324.
HUSB332A is internally integrated with Ra resistor and VCONN diode, which can realize zero peripheral design.The built-in burning storage unit (OTP) can support multiple burning.HUSB332A can also support Type-C finished head or finished cable system burning through CC pin.CC, VCONN1 and VCONN2 pins of HUSB332A all support 25V high withstand voltage.
Cut the data line to observe the section. Two red thick cores are positive power cores, yellow is VCONN core, blue is CC core, white green is USB2.0 core, and negative is composed of multiple bare cores.
Cut the outer skin of the cable, and the inside is a woven shielding mesh.
Below the screen is a layer of shielding aluminum foil.
The interior of the shielding aluminum foil is the power wire core and data wire core, and the interior is also filled with anti pull wire.
At a glance, the cable cores inside the cable will be introduced in detail below.
The two red positive power wire cores are tinned copper wires with anti pulling wires inside.
Close up of blue CC wire core, with anti stay wire inside.
The yellow VCONN core also has anti pulling wire inside.
For the data line used for USB2.0 transmission, the green D+core has an anti pull wire inside.
White D-wire core also has anti stay wire inside.
Five bare cores are used for negative power transmission.

Take a look at all of them and have a family photo.
Disassembly summary of charging head network
The USB-C data cable of Lvlian is 2 meters long and supports 100W fast charging and USB2.0 data transmission. It is suitable for fast charging of laptops, mobile phones and mobile power supplies. The cable uses plastic injection terminals, which is practical and beautiful.
The charging head network learned through disassembly that the USB-C data cable of Lvlian uses injection molded USB-C terminals, the internal plug is spot welded to the stainless steel shell, and is filled with hard glue to increase the mechanical strength.Thickened wires are used inside the cable, and woven shielding mesh and shielding aluminum foil are set, and anti stay wire is filled to increase strength.E-Marker chip is from Huinengtai, model HUSB332A.The cable is solid, reliable and durable.
