Recently I like to study things that are convenient for charging
In order to measure the influence of the wire resistance on the pressure drop, we started with an adapter plate.
Of course, this adapter board can also be used to perform various interface conversions and can be used when necessary
The adapter board supports five access modes: lightning interface, type-c, micro USB, mini USB, and terminal.
Finally, there will be no-load, 1A, 2A, 3A load test data for all lines on hand, all of which are dry goods.
Hard test for a long time, need everyone's broken silver support! Thank you for your valuable friend!
Second, out of the box
Yuantong express really annoying, send and receive points so far
Open the express parcel, which is a small paper box. Such a small thing is packed in carton.
Inside the carton is relatively simple, a bag that can be sealed
There are two things inside, one certificate, one adapter plate
Five sockets from left to right, lightning, micro USB, type-c, mini USB, terminal
On the other side, once from left to right, it is a USB male head, a forward and reverse plugged USB female head, and an ordinary USB female head.
Look at the solder joint of the USB plug, more uniform, not very full
The USB male and female heads on both sides have corresponding terminals for convenient wiring and measurement
Remove the USB male and female ends on both sides
Other sockets have no chips, only lightning socket uses three chips, macro screen printing, 92cd37
C009t FET
Note : The charge head is selected by anker's powerport+6 charger, the socket is selected QC2.0 socket
The YZX green watch is used to measure the meter. The only watch on hand is accurate.
The load is EBD-USB+, and the load current at the computer is set to 1A, 2A, and 3A for comparison test.
The total table, all the data are in this, indefinite ranking, according to the test sequence sort
Type-c interface line ranking
Lightning interface line rankings
Micro USB interface line ranking
1, adapter board is still very easy to use, plug is very smooth, almost all of the mainstream plug, you can easily measure and transfer
2, the adapter board's resistance is still there, and the adapter board there is a blue led light will be lit, so the above only test the pressure drop, there is no calculation of resistance and the like data, this adapter board can be used to Hengping For comparison tests, it is also necessary to pay attention to the own resistance of the adapter board when testing a single line separately.
3, the positive and negative plug adapter USB female head is still very good, you can easily insert a variety of measuring meters and wire
4, the above line pressure drop data comparison is more useful, it is not meaningful in terms of a separate, but it can be clearly seen that the resistance of the wire for charging speed is still a great impact
5, choose a good charging line, it is still necessary
Six, test picture appendix
The following is a screenshot of the test data, which is the contents of the above chart
No-load voltage data
One plus three original line test chart
Huawei original line test chart
Oreco line test chart
Apple's original test chart

You can see this is true love! muah!
thank you all!
