Thirty-two Charging Trines Thirty-six: Length Collocation and Charging Don't Care - ORICO 5A Line (0.5m & 1m) With Internal Resistance Test

I. Introduction

Oerlikon's 5A online time has left us with a very deep impression, cheap prices, with a small line resistance and a good appearance to work, is simply a must-have line for Type-C users.

This 5A cable is not to say that there are no shortcomings. The lack of support for Huawei's Mate9's FCP is one of the few limitations of this line. Of course, it is not a complete lack, and my various QC devices are compatible.

However, Orrick timely improved its products and quickly launched the new 5A cable to support Huawei's FCP fast charge.

Find ORICO ORICO Type-c data cable 0.5 meters 9.9 yuan (photographed legislation reduction) value of friends broke the original: ORICO Oreco Type-c data line 0.5 meters, Tmall ORICO original price of 15.9 yuan, photographed Set aside 6 yuan, and pay as little as 9.9 yuan for shipping. You can start with what you need. ORICO ORICO Type-c5A fast-charging data line, support 5A high current output, Scharge fast charging technology, the core uses two sets of 22# bold copper core, dual-core two series, environmental protection TPE material, value 2 Comments 12 Collection 5 Direct link details

Second, out of the box

â–¼ white courier bag looks better than gray

â–¼ After opening the courier bag, two 5A lines of different lengths are filled with bubble paper bags. For a line, the protection is good.

â–¼ The packaging of the data cable is white and green, the middle is the color printing of the data cable, the above is the brand logo and English name of Oerlikon, and the bottom is the four characteristics of the charging cable.

â–¼The information on the back is more abundant. Firstly, the length of the wire is clearly marked in the upper right corner, then the middle is the data line parameter, and the bottom is the data line barcode.

Product Name: TYPE-C 5A charging cable

Product Model: ORICO AC5

Product Specifications: USB-A to TYPE-C

â–¼ Open the data line box, inside a transparent plastic bag with a data line and a contact card

Third, the appearance

▼ The USB interface of the charging cable is printed with the Olympico brand LOGO, and the outgoing line protection is printed with the letter “H”.

â–¼The USB interface is marked with the "5A" printed on the back of the USB interface.

â–¼ Let's take a look at the contacts on the USB interface, the contacts are full, and the positive and negative contacts are widened to further reduce the contact resistance.

â–¼ Zoom in and see, the contacts are really wide

â–¼Type-C interface, the front is empty, printed on the outlet protection "5A"

â–¼The back is empty, and the word "5A" is also printed on the outlet protection.

â–¼ look at the contact details, the pin is not complete, it should be USB2.0, but the contact is full

â–¼ Zoom in to see

â–¼Look at the length of the charging cable, the length of 50cm is about 50cm, just

â–¼100cm length of the line is slightly longer, about 101cm or so

Fourth, test

▼ When the new equipment was changed last time, this time when the new equipment is flexing its muscles, the line resistance of this line can be directly measured. The line resistance of 50cm length is about 50.078mΩ.

â–¼ Everyone must be very interested in the measurement process. Let's take a look. The first step is to adjust the interface to measure the resistance, and then press the button for a long time.

â–¼ Enter the line resistance measurement mode, as shown in the chart above, first insert the meter into the charging head, measure the no-load voltage of the charging head, and automatically enter the next step after the measurement is completed.

â–¼ and then connect the load, select the current to be greater than 0.5A, this load current is about 1A, automatically convert the picture after the measurement is completed, automatically enter the next step

â–¼ Use the line to be measured to connect between the charging head and the table. At this time, unplug the watch and the load

â–¼ Insert the line under test between the charging head and the load, check, no-load voltage

â–¼ Then insert the load, the current is the same as before

▼ After a period of testing and calculation, you can display the results, 100cm long 5A line, line resistance of about 62.541mΩ, this line resistance is very small, under normal circumstances is less than 100mΩ charging line is a very good line, this Oricon 5A line is much lower than 100mΩ

â–¼Then this measurement will be saved until the next measurement

â–¼ Charging measured, QC2.0 handshake without pressure

â–¼QC3.0 handshake is not the same pressure

â–¼PE fast charge can trigger, there is no device to support Huawei FCP, can not measure, sorry

V. Summary

1, Orrick's 5A line appearance is still possible, is not aware of this 5A line of white skin with a long time will not be dirty

The line resistance of the 2 and 5A lines is very small, the line resistance of 50cm is about 50mΩ, the line resistance of 100cm is only 62mΩ, the line resistance is small, and the main resistance is the contact resistance.

3, the daily mainstream fast charge this line can support, there is no Huawei equipment, can not test FCP, sorry

thank you all!
