Don't be greedy for small and cheap power cable/data cable

First of all, thank you for your computer trial. I don't know how to start, so let's talk about the purchase of data lines first.

For mobile phones and other electronic products that need to be used with power adapters, what we have been unable to get rid of is the endurance and charging performance. For mobile phones, the battery capacity is fixed, so there will be obvious differences in the endurance of different mobile phones. But no matter what kind of mobile phone, in addition to the demand for performance and endurance, we are paying more and more attention to the charging performance. It is not only related to whether the mobile phone supports fast charging, but also related to the power cord. This is a detailed impact. It not only affects the charging speed, but also, to exaggerate, affects the battery life and even the life of the mobile phone. For example, some low-quality iPhone power cords on the market may not be able to charge properly, and some can be used at that time but cannot be used after the IOS system is upgraded. For micro of some Android phones Some USB power cables can only charge the mobile phone and cannot transmit data. Some data cables will generate obvious heat when charging. Therefore, for the purchase of power cord, try to choose official or well-known brand products, and do not covet cheap.

In the official publicity of some data lines, we often see several wires, metal woven mesh, and aluminum foil shielding layer. Are these really important? It is important and necessary, which is why their prices are generally high.

The number of wires and the materials used can be said to directly affect the speed of charging. The power cables that need to transmit data such as mobile phones and tablets generally contain four wires to realize power supply and data transmission. The common materials are copper wires, tinned copper wires and oxygen free pure copper wires. After studying physics, we all know that the thickness and length of the wire are related to the resistance and the current. The thicker the wire is, the greater the current will flow through it, and the faster the charging will be. Here is a unit to be explained: AWG (American Wire Gauge (American Wire Gauge), which is a unit of wire thickness, is one of the design specifications for the internal composition of wire materials, and is also the most commonly used industrial standard at present. The smaller the AWG value, the thicker the diameter of the wire, the larger the current the wire can carry, so there is a saying that the thicker the data wire, the faster the charging. For stable data transmission, the problem of electromagnetic interference needs to be considered, so the appearance of metal woven mesh is necessary to shield interference and ensure stable data transmission. For the aluminum foil shielding layer, in addition to further improving the stability of signal transmission, the most direct role is to protect the internal wires from being pulled and deformed. Therefore, even a small power cord has its own problems.

Type-C and USB3.1

Type-C has gradually become popular on mobile phones, tablets, computers and other devices. Type-C is no longer divided between the front and the back to achieve blind insertion. At the same time, it can achieve the function of video output, and has significantly improved the power supply performance. For example, Type-C to VGA, HDMI adapter cables already on sale, but the price is currently on the high side. Type-C is only a physical specification, and there can be many kinds of buses, which means there will be differences in data transmission. What is the relationship between USB3.1 and Type-C? It's actually very simple, USB 3.1 It is an industry technical standard, not a real product. USB Type-C is an actual product designed based on USB 3.1.

Short but not thin ORICO AC5-5A data cable

The advantage of Type-C interface is that it can freely plug in and out, which is a common micro What USB interface does not have. ORICO AC5-5A is made of TPE material, which is soft. The plugs at both ends are made of anti oxidant and rusty nickel plated alloy, which is resistant to plugging. At the same time, the ends are thickened, which reduces the wire breakage caused by frequent bending. The data line is internally made of double stranded 22AWG copper wire core, which is processed with aluminum foil+woven mesh double-layer shielding material to ensure better transmission of 5A current and stable data transmission.

Compared with the other two Type-C wires, the upper part is the power cord of the smart scale, the thinnest of the three; Orico data line in the middle, with the thickness in the middle; The black part below is the power cord of the mobile hard disk, the thickest of the three.

This is the part of the USB interface of the three types of wire, and there is little difference in the process treatment. The three cables are in three colors, from left to right, Orico, mobile hard disk cable and smart scale power cable.

Stable charging performance and data reading and writing performance

The three devices matched here are Yunmai intelligent body fat scale, Linkreal Type-C mobile hard disk box and Taidian Tbook 16 Power. They are compared in terms of charging performance and read-write data.

The smart scale can be charged normally with the same power adapter. The charging time from low power off to full power is about 16 minutes faster than the original data cable.

In the test of the matched mobile hard disk, the hard disk is WD 1TB blue disk, the hard disk case is a linkreal Type-C, and the matching notebook is a ThinkPad T520 (Win10 X64)， Use the same USB interface for testing. The first concern in the experience is that it can be recognized by the system normally, and the second is that the read/write speed cannot be significantly lower than the original data line.

The matched Orico data line can be identified by the normal cup system, and there is no significant difference between the original line and the reference rate test.

Type-C is becoming more and more popular in mobile phones, tablets and computers, such as this TV Tbook sixteen Power， In addition to the traditional DC charging port, Type-C interface is also designed, but Type-C power cord is not provided. As a multi-functional interface, Type-C interface can not only charge the device, but also be used as a video adapter.

Fortunately, the power adapter provided adopts a separate design, which can be used with USB interface wires. This also enables Orico Type-C to compare charging efficiency with original DC wires.

The following figure shows the instant charging power of the same panel with Orico, hard disk data cable and original DC cable. The panel can be charged normally with the Tye-C data cable, but the charging efficiency is lower than that of the DC cable, which means that the charging time is longer.

In general, Orico AC-5A data cable is more secure in the design of double ends, more convenient in plugging, and the environmentally friendly TPE material is soft and not easy to break. It can be used with different Type-C devices to achieve stable charging effect and data transmission, which can meet the needs of daily use.

With the more appearance of Type-C interface devices, a variety of cheap products of Type-C data cable can also be increased, so we should pay more attention to the purchase, not only for charging safety, but also for the safety of equipment use. For the purchase of Type-C data cable, the focus is on the material, internal material, interface design, charging speed and data transmission stability, which can generally be found in the official introduction, but the latter two parts are related to the actual use. The official data and publicity can only be a reference. We can only say yes or no after the actual experience, It is necessary to choose products of big brands as far as possible.
