According to the previous unpacking introduction,iPhone 15All series of mobile phones still have no charger, or later models will not appear;At the same time,iPhone 15、iPhone 15Although the USB Type-C charging port of the Plus mobile phone only supports the USB 2.0 transmission specification, it supports DP video transmission. Does the attached braided wire support it?How about the specific performance?
Product Introduction
Clear thinking, first look at the product.
Accessories in package exceptiPhone 15In addition to the mobile phone itself, its supportingCharging lineThe materials are still tied and fixed with "environmental protection" paper tape, which is USB-C to USB-C typeCharging lineWood.
iPhone 15Mobile phoneC to CCharging lineThe body is white woven design, which is consistent with the matching wire material of the previous new iPad Pro. The fiber yarn is twisted into a strand and then arranged and woven, which is not easy to tangle and has a longer service life.
The junction between the braid body and the sub end joint shall be smooth, transitional and jointed. The plastic shell of the thread head shall be designed with bright surface, and the transition on both sides shall be smooth.
The wire model: A2795 and product serial number are printed on the metal interface.
IPhone 15C to CCharging lineThe internal part of the interface terminal is designed with a specially designed pin pin. The male and female socket interfaces are universal and support forward and backward blind insertion.
The POWER-Z KM002C test failed to identify, that is, the cable does not have an E-Marker chip.
IPhone 15C to CThe diameter of charging wire body is about 3.16mm.
IPhone 15C to CThe most obvious difference between the charging wire and the original conventional C to C wire, except for the braided material, is that the sub end housing of the new wire is slightly shorter.
performance testing
The test of wire rod is mainly reflected in two aspects: functional test and the quality test of wire rod itself.The former mainly tests which functions the wire supports and whether it supports fast charging, data transmission and video transmission;The latter mainly tests the internal quality of the wire rod, involving specific test items such as voltage drop. Here are the test results of the functions of the C to C charging line of iPhone 15.
Quick charge
Since it is wire material, charging must be tested. Let's test it.
Use Apple 30W charger with original cable to charge iPhone 15, and the measured output power of the charger is about 8.81V 2.63A23.19W, the charging current is 2.63A。
The Apple 140W charger is used with this cable to charge the iPad Air 5. The measured input power of the current panel is 14.56V 2.26A 32.91W, and the charging current is 2.26A.
The original 140W charger is used with this cable to charge the MacBook Pro 16 M1 Max 2021 notebook. The measured input power of the notebook is 19.95V 2.97A 59.18W, and the measured current is 2.97A3Awire rod.
data transmission
For a data cable, charging is the basis, while other functions are advanced.Next, let's see if the wire equipped with iPhone 15 series phones supports data transmission.
Connect Apple's new C to C charging wire to the notebook computer and the hard disk box. In the hard disk box is the Samsung 970EVO solid disk drive. You can see that the hard disk icon is successfully displayed on the desktop of the computer at this time.
On the computer side, use Disk Speed Test to test the data transmission speed. The measured write speed is about 35.9MB/s, and the read speed is about 38.8MB/s, which conforms to the USB2.0 data transmission standard.
video transmission
Finally, let's see if this cable equipped with iPhone 15 series phones supports video transmission.
Connect the two ends of the wire to the Type-C interface of the MacBook Pro laptop and the Type-C video input interface at the bottom of the display. The actual measurement shows that the display cannot be lit normally, which confirms that the wire equipped with the iPhone 15 series mobile phone does not support video transmission.
Pressure drop test
Voltage drop test is an important factor to measure the quality of wire rod. In daily use, it charges the mobile phone. The voltage and current are output to one end of the wire rod through the charger, and then transmitted to the other end of the wire rod to the mobile phone. The transmission of both ends of the wire rod involves voltage drop data.
Connect the two ends of the wire to the power supply instrument and the load instrument respectively. This time, the charge voltage and output voltage of the wire at different gears are tested respectively, and the travel value is calculated. The difference is the value of the voltage drop;A total of 10 gears were tested this time, and the test results are as follows.
It can also be seen from the histogram that the gear with the highest difference is 15V3A、12V3A0.58V for 9V3A, 5V3A and 20V3A, and the gear with the lowest difference is 0.19V for 20V1A, 5V1A, 15V1A, 12V1A and 9V1A.
Summary of charging head network
This wire equipped with iPhone 15 series mobile phones is made by precision knitting process. The wire measured by POWER-Z KM003C tester has no E-Marker chip, which is a 3A charging wire.
In terms of charging, this cable supports the highest level60WThe power transmission capability can meet the fast charging requirements of thin and light notebook computers, while the data transmission is still USB 2.0, which is only applicable to small file transmission. At the same time, it does not have the video transmission capability. Users need to purchase additional wires to realize the external display function of iPhone 15 series mobile phones.
