Step 1. Appearance and basic specifications
Specification:
Model: IET2020C11
Material PU +Aluminum alloy
Connector USB C/Lighting /Micro
power 15W/ 20W
Output 5V 3A/ 9V 2.25A
Length: 1.5M
On the basis of traditional charging cable, leather is added and stitched with nylon thread. Aluminum alloy shell is used at the joint. The classic black and white combination looks simple and generous.
The measured product weight is 35g , Due to the addition of leather, the overall will be a little heavier than ordinary cables.
Test wire diameter 3.83mm，The wire diameter is also a bit thicker than ordinary cables, due to the addition of leather.
The length is 1.5M, which is more convenient and reasonable in daily use.
Step 2. Functional test
Mobile phone charging test，
Connect the computer to transfer the data in the mobile phone. The test result supports data transmission and the transmission speed is normal.
cable resistance test，The resistance is only 0.002389 ohms, which is very small.
The input voltage and current are 5V /2A, and the output voltage and current is 4.87V/2A. Due to the loss of the machine and connectors during the test. This pressure drop is within the normal range.
Step 3. Disassemble
The aluminum alloy shell and the twill design are added to the plastic joints, which are non-slip and easier to handle.
Cut open the aluminum alloy shell and internal adhesive layer, you can see the PCB and core welding. This glue is very difficult to peel off.
Cut out the nylon sutures and take apart the leather outer skin. You can see the black PVC outer skin with four conventional thread cores inside. Still the same, the two thick power lines and two thin data transmission lines.
Step 4. Summarize
The design of the leather cord is not easy to break the cable, and the length of 1.5 meters is more suitable for use while charging. Basic functional test and performance test are qualified. It is a good choice.
