preface
Previously, the charging head network received a Lenovo 65W charger, although it was a product two years ago, but with excellent charger firmware and highly integrated components, it is also considered a "table of talents" today. And this charger is equipped with a data cable as standard, a milky white cable body, the degree of refinement of the workmanship looks like the charger is comparable, so let's see what functions this cable has in addition to charging.
Product introduction
The wire is bundled with a storage strap, so don't think about the packaging.
C2C terminal configuration, terminal shell and tail using injection molding, the transition is smooth and burr-free, large factory workmanship.
The length of the wire is about 178cm, which is quite enough.
16pin USB-C male, see the two sides of the empty pin, you probably know that it is USB 2.0 specifications.
Read the cable terminal chip data using the POWER-Z KM002C, which has a built-in E-Marker chip that supports 100W of high current passage and a transmission specification of USB2.0.
Wire testing
For the evaluation of the performance of the wire, there are no more than three kinds, whether it can be charged, whether it can transmit data, and whether it can transmit video signals. A little more advanced is whether to support fast charging, fast charging of transmitted data, bandwidth of transmitting video signals, etc. Let's test this data line attached to lenovo 65W charger.
Fast charging
Using a flash pole 140W Gallium Nitride charger with a fast charging cable to charge the normal 100W input charger, the power is 20.48V 4.8A 98.3W, and the cable supports 100W power transfer.
To charge the MacBook Pro 16 2021, the charger outputs 20V high voltage, and the power is around 95W.
Charge the Black Shark 5 Pro with a power of 17.22V 5.11A 88.16W.
Charge this 100W charging treasure of AOHi, and the power comes to 102.43W.
brief summary
In terms of fast charging, the actual test has been carried out for laptops, mobile phones, and charging treasures, the power is about 100W, and the cable supports the power transmission of 20V5A 100W, which is in line with the POWER-Z KM002C for the reading of wire information.
Data transmission
Let's take a look at whether the cable supports data transmission, the two ends of the wire are connected to the hard disk box of the notebook computer and the internal solid state drive, at this time the computer reads the hard disk, proving that the cable supports data transmission.
The actual test showed that the write speed is about 38.1MB/s and the read speed is about 38.7MB/s, which is often referred to as the USB2.0 transmission standard.
brief summary
Lenovo 65W charger standard this data cable in addition to supporting 100W fast charging, but also support data transmission, nearly 40MB / s data transfer speed daily use simple transfer of small files is enough, but if you want to transfer large files or recommend the use of other cables, otherwise it is easy to get mad.
Video expansion
Finally, let's take a look at whether the cable supports video transmission, connect the two ends of the cable to the laptop and the monitor, after the actual test can not light up the display, Lenovo's charger standard fast charging line does not support video transmission.
brief summary
As a 65W charger standard fast charging line, Lenovo's C2C fast charging line supports 100W high-power fast charging, supporting data transmission has been very sincere, after all, it is an attached cable. If the video transmission function is added, I am afraid that the price of cable or charger kit will skyrocket.
Charging head net summary
This comes with a cable from lenovo's 65W charger, the milky white appearance and charger matching, the length of 1.78 meters to meet the daily needs of most people. And the cable performance is not too many surprises, support 5A large current, the highest compatible with 100W PD charging; data transmission specifications are USB 2.0, upload a small file what is not a problem, video expansion is not very good.
