In the subway after work, you can always see the young office workers holding the power bank,Charging lineWrap it in the hand in a circle, or only put it in the side pocket of the backpack.
The charging head network has received a model from AOHiMFiCharging lineSet, not only hasMFiCertified C to Lightning wire, and can pass the“Docking”The charging head network will introduce the wires in the package one by one.
Product Introduction
As usual, look at the packaging first.
Charging lineThe front of the package box is bright printed with the word "FUTURE" printed on it, and the grid stripe design below is actuallyCharging lineSchematic diagram after connection;In the transparent cabin designed with "!" on the right side, you can see that there are Lightning type wires, which have passed the“MFi”Certification.
The back of the packing box is similar to the design of the spaceship operating platform;The diagram in the left column indicates that the wire can be“Docking”, customized connection length and charging indicator: low current (green), standard charging (blue), fast charging (yellow flashing);In addition,extended lineThe material supports 240W power transmission and the length of each wire.
The packing box adopts the design of "heaven and earth box", and the internal wires are fixed in the black foam of "tailored design".
Take out all items, including C to Lightning wireC to C wire, two wires with different lengthsUSB-CThe adapter cable, a double headed fixing nut, a rubber storage box and a paper jam of instructions for use.
C to Lightning wire is packed in a separate box and has“MFi”Certification mark;The wire is made of yellow braided wire, and the sub end shell is made of alloy metal. The connection with the wire body is made of three-stage integrated injection molding, and the surface is flat without burrs.
Use POWER-Z MF001 tester to test Lightning terminals, and the measured terminals are original C94 terminals, scoring 100 points.
The design of C to C wire is the same as that of C to Lightning wire, which also adopts the design of braided body.
Only the sub terminal housing with thread in C to C wire is equipped with a charging indicator.
During charging, different colors are displayed according to the corresponding charging power. For example, the above figure is a yellow flashing indicator in the fast charging state.
USB-CThe adapter cable is also designed with a braided body, which hasUSB-CTerminals andUSB-CThe USB-C port is designed with alloy double head fixing nuts.
The length of the spring-loaded USB-C adapter wire is increased only, and other designs are consistent.
The close-up of the USB-C port of the USB-C adapter line is consistent with the USB-C port of the charger, and the rubber core of the female port is black.
In addition to the double head fixing nuts configured for two adapter lines, a spare nut is also provided.
Connect USB-C wire with adapter wire“Docking”See the figure above.
The length of C to Lightning wire is about 17cm.
The length of C to C wire is about 16.5cm.
The length of USB-C adapter cable is about 88cm.
The straightening length of spring-loaded USB-C adapter cable is about 194cm.
All wires weigh about 150.9g.
Charging test
Next, the wire will be used for charging measurement.
Use C to Lightning wire and Apple 35W charger (A2676) to charge the iPhone 14 Pro Max, and the measured power is 8.89V 2.96A 26.33W, which meets the fast charging requirements of the iPhone.
Use C to C wire and Nubia 120W charger to charge the Black Shark 7Pro, and the measured power is 17.83V 5.37A 95.67W, which meets the fast charging demand of the Black Shark 7Pro.
Use C to C wire“Docking”After the USB-C adapter line is equipped with Huawei 90W charger to charge Huawei P40 Pro, the measured power is 9.24V 3.87A 35.79W, which meets the fast charging requirements of Huawei P40 Pro.
Rate test
Connect the C to C wire to the laptop and the hard disk box respectively. The hard disk box is a Samsung 970EVO solid state disk. It can be seen that the hard disk is successfully read on the desktop of the computer at this time, indicating that the wire supports data transmission;And use Disk Speed Test on the computer side to test the data transmission speed.
The measured write speed is about 38.9MB/s, and the read speed is about 35.8MB/s, which conforms to the data transmission specification of USB 2.0.
video transmission
C to C wire is used with the fourth generation 11 inch iPad Pro for video expansion test. It is measured that this wire does not support video transmission function.
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 both 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 difference is the value of the voltage drop.
It can be seen from the data that the pressure drop of gear 1A is about 0.09V;The pressure drop of gear 3A is about 0.23V;The pressure drop of 5A gear is about 0.35V.
Let's see how the pressure drop data of the combined wire rods are.
Combine three sections of wire rods, and the combined length is about 3m. Test the voltage drop, and then summarize the test data into a table.
It can be seen from the data that the pressure drop of 5A gear is about 1.46V;The voltage drop at 3A gear of 5V, 9V and 12V is about 0.85V;The 1A voltage drop of 5V, 9V, 12V, 28V is about 0.3V;The pressure drop of 15V3A and 20V3A is about 0.24;The voltage drop of 15V1A and 20V1A is about 0.09V.
Summary of pressure drop test
It can be seen from the test that the voltage drop difference becomes larger and the charging power decreases after the wires are combined, thus the charging efficiency will be reduced.
Use Scenarios
When using iPhone for wired charging, it can overlap with the power bank, and has the right length requirement,The same is true for C to C wire.
When used on the desktop, the wire can be used“Docking”It can meet the length requirements of the desktop when used.
At the same time, the "docking" of three sections of wire can fully meet the demand for the length of power taken from the power bank placed in the bag. Users can select appropriate wire for "docking" and adjust the charging posture.
Summary of charging head network
AOHiCharging lineAll wire sub ends in the suit are formed and fitted smoothly in the mold at the connection of the wire body, all of which are designed for braided wire body, which is more wear-resistant and resistant to bending, and the wire is flexible;It also has a rubber storage box, which is more convenient to carry and store when traveling.
In terms of performance,The C to Lightning charging cable can only be used for iPhone charging. The above test parts should be measured around the new iPhone 14 series. It can be seen that the charging experience is the same with the original charging cable when it is paired with the original PD charger;Measured C to C wire and USB-Cextended lineAll materials are 5A wires, which can support up to 240W power transmission and USB 2.0 transmission rate.
Overall,AOHi charging line kit hasMFiCertified C to Lightning wire, realizing the use experience of original iPhone wire;With "docking" capabilityextended lineThe material can meet the use needs in various scenarios, with a maximum length of 3 meters. Users can match it as they like.
