How to choose an iPhone USB-C charging cable?

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.03.11
In order to avoid high fines for violating new EU rules, Apple abandoned the Lightning interface that was born in 2012 and changed the charging interface of all iPhone 15 series to Type-C interface. For a while, many fruit fans were a bit uncomfortable, and how to purchase new charging heads and data cables became a new problem.

In fact, the Type-C interface only unifies the shape of the interface, which still includes many concepts such as USB4, Thunderbolt, Thunderbolt, and fully functional C-ports. The charging cables on the market also use the Type-C interface, with prices ranging from a few yuan to several hundred to thousands.


So how do you choose the right charging cable for your iPhone? What are the differences between Apple original cables, Android official cables, and third-party brand cables?

Kinri Energy has specially prepared original fast charging kits from Apple, Huawei, Xiaomi, OPPO, and vivo, as well as charging cables from well-known third-party brands such as Greenlink, Bess, Pinsheng, and Romance, as well as miscellaneous charging cables and a magnetic design charging cable.

Next, Kinri Energy will conduct a horizontal comparison of 11 products, comparing them one by one in terms of charging speed, transmission speed, and wire design.

Charging speed

Kinri Energy will use the same iPhone 15 Pro Max for all subsequent tests, which will be referred to as the iPhone in the following text.

Testing process: First, drain the iPhone's battery to the warning line of 20%, and then use different charging cables for testing one by one. The testing process involves charging from 20% to 30%, recording its charging time and peak power. After each test is completed, we reset the battery to the 20% level.


It should be noted in advance that we consider that the charging devices randomly included by these brands all include a charging head and a charging cable. Consumers of these brands are likely to have a complete set of chargers at home, so the chargers used for this part of the testing are all from their respective brands.

From the test results, it can be seen that the performance of Apple, Xiaomi, and vivo's original chargers is relatively similar. Among them, the vivo charger has the highest peak power, reaching 26.4W, and a charging time of 4 minutes and 51 seconds, which is also the shortest time consumption among these brands.

However, there are some differences in the test results between Huawei and OPPO. The original Huawei charger did not respond when connected to the iPhone. The iPhone 15 series supports the PD fast charging protocol, and the charging cable that Huawei comes with is a "straight line" without an E-Marker chip, which prevents the iPhone 15 series from obtaining cable information and recognizing the PD fast charging protocol, making it impossible to charge. The Huawei original charging head and Apple original charging cable can charge normally, and the peak power and speed are not inferior to the official Apple package.

The peak power of the original OPPO charger is only 7.7W, and the charging time took 15 minutes and 6 seconds. The reason is also very simple, because OPPO's VOOC flash charging technology adopts a "low voltage and high current" scheme, which is not compatible with the PD fast charging protocol. Therefore, when using the OPPO charging kit, iPhone 15 series phones can only activate the DCP common charging protocol, which means they will charge very slowly.

Let's take a look at the charging performance of third-party cables. We used the official 30W charging head of the iPhone and conducted charging tests with the remaining 6 products. The final results are as follows:

The performance of the six products is relatively consistent, with a peak power of around 25W and a charging time difference of less than 10 seconds. When we add the official iPhone charging kit for comparison, we will find that everyone's performance can be said to be evenly matched, including even a miscellaneous charging cable that costs just over 10 yuan.

Of course, there cannot be a single problem with third-party charging cables. Firstly, there is a heating issue, as there is slight heating at the joints of the miscellaneous charging cables and magnetic suction cables during the charging process. Secondly, when holding the phone while charging, there will be a slight warmth sensation when the fingers touch the connector. This situation did not occur with other third-party brand wires during the testing process.

If we only talk about the charging process, the official charging packages of Xiaomi and Vivo, as well as four third-party cables, are very compatible with the iPhone 15 series phones.

Data Transmission

In addition to being able to charge, data transmission is also an important function of cables, especially after the C port of the iPhone 15 Pro series supports USB 3.0, data transmission speed will become a highlight. But the iPhone comes with a random data cable that only supports USB 2.0. We also conducted a round of data transfer testing on the cables we have on hand, transferring large video files from the phone to the computer. The test results of all cables are as follows:


Their transmission speed is basically the same, but of course, even after Huawei's data cable is plugged in, there is still no response and data transmission cannot be carried out.

From the parameters on the packaging, we can also see that the maximum transmission speed of these wires is 480Mbps, which is a very standard USB2.0 specification. This also means that whether it is the performance of charging or the speed of data transmission, there is not much substantive difference between Apple's official cable and the several cables we tested. Is there a difference in workmanship, texture, and portability?

Wire design

When it comes to workmanship and texture, the woven wire that Apple comes with randomly has a good hand feel. The advantage of the woven wire is that it is easy to curl and store, and there is no need to worry about breaking or opening the glue if the bending degree is too large.


The cables of the four mobile phone brands are made of TPE material, which is currently the most common material for charging cables. However, everyone should have experienced its drawbacks, such as strong toughness and difficulty in bending. Long term forced bending can also easily lead to skin bursting and breakage. These charging cables are all flagship standards in terms of workmanship, but they are not particularly convenient to store. If you have a need to bring a charging cable out, it is still recommended to choose a woven material charging cable.

summary

After a complete experience, we can find that there is not much difference in performance between the official charging cable for over a hundred yuan on the iPhone and the affordable third-party charging cable. In terms of portability, some third-party products even do better than the iPhone. If ordinary users do not have special pursuits, there is no need to purchase the official cable. Choosing a reliable third-party brand is also a good choice.

If we recommend a third-party brand charging cable that best matches the iPhone 15 series based on Kinri Energy's subjective feelings, among these products, we would choose Pinsheng's woven material charging cable. Whether it's charging, data transmission, or portable design, its comprehensive experience is the most satisfactory, and its price is not the most expensive.
