Type-c (USB-C) has been attacked, and various Type-C devices have quietly entered our lives. The new mobile phones from all major mobile phone manufacturers are equipped with type-c interfaces, and mobile power supports type-c. There are quite a few products. The benefits of type-c support up to 100W 20V5A power pass, positive and negative blind plug, audio and video charging one line package and USB3.1 support.
The latest flagship machine Meizu PRO6, Huawei P9, Xiaomi 5, are equipped with type-c interface, then make a horizontal comparison of these three original data lines.
The equipment is as follows:
Meizu PRO6 original data line x1 (referred to as Meizu line); Huawei P9 original data line x1 (referred to as Huawei line); Xiaomi 5 original data line x1 (referred to as millet line).
The type-c line of three mobile phone manufacturers.
From the left to the Meizu, the middle of Huawei, the right millet, the back is also arranged in this order.
Meizu line rolled up, there are two clips, Huawei line translucent rubber sleeve, millet line rubber band.
The male and female heads of the three lines.
The angle of the small hot pot can be seen inside the approximate contact.
The three lines are put together and the Meizu line has the largest head.
The length of the three lines, the Meizu line is the same as the Huawei line, both 102cm, the longest millet, reaching 120cm.
The male head can be magnetized, the type-c is weakly magnetic, and the rear cut is estimated to be stainless steel.
Three wire type-c output ports.
Conductivity test
The voltage values ​​in the 5V low voltage mode are as follows:
The current in the 5V low voltage mode is as follows:
It can be seen that the Huawei wire has the best conductivity.
The voltage values ​​in the high-voltage fast charge mode are as follows:
The current in high voltage fast charge mode is as follows:
It can be seen that different data lines perform best when they are powered by their own brand of mobile power.
The table is now summarized as follows:
The voltage is measured at a fixed current load.
Data transmission capability test
Test conditions: Use the ATTO Disk Benchmark software to measure the mobile hard disk using 4 different data lines on the same computer. The mobile hard disk is Orico USB3.0 Type C 2.5′′ Hard Drive Enclosure.
Using the Meizu data cable, the write/read speed exceeds 300MB/s in USB3.0 mode, which fully demonstrates the advantages of the USB3.0 5Gbps interface.
With the Huawei data cable, the write/read speed is 40MB/S in USB2.0 mode.
With the Xiaomi data cable, the write/read speed is 40MB/S in USB2.0 mode.
Cut all.
Three wire cross sections are compared.
After the three lines are removed, let's take a look.
A clear structure.
Contact part: left from Meizu, Huawei, Xiaomi.
Both ends are put together for comparison.
The components of the three lines, from left to Meizu, Huawei, Xiaomi.
Type-c port close-up.
USB-A port close-up.
The back of the USB-A port.
All lines of the three lines.
to sum up:
Meizu line uses the USB3.1 standard, the line body is soft, and the data transmission capability is super strong;
The Huawei line uses the USB2.0 standard, which can over-current, and the current circulation capability is close to that of Meizu, but the four lines;
Xiaomi is also a USB2.0 standard. The head has no extra metal parts. It is filled with hard rubber. It is directly molded and wrapped at both ends. The wire is the thinnest and hardest. The 3A high current cannot pass, and the current circulation capacity is normal.
