Many friends have bought the iPhone 15. Since the iPhone 15 this time has been replaced with a USB-C port, which is also a Type-c port, it is necessary to prepare a few more Apple charging cables, one at home, one in the car, and one in the office. root.
Many people want to take advantage of the current business activities and stock up on a few more cables for backup. However, when buying Apple iPhone15 charging cables, you really don’t need to buy them randomly. I’m not sure whether it will burn the phone or not, but you might be cheated. Paying more IQ tax will be very helpful. normal.

1. If you want to buy a dual-head USB-C interface, don’t buy one with USB-A on one side and USB-C on the other.
We know that many data cables for now mobile phone have a USB-A interface on one side and a USB-C interface on the other, so there are many such cables, but we recommend not to buy them.
Because many of these USB-A to USB-C interface cables are modified by magic and do not support all the protocols. Once the PD protocol is not supported, fast charging cannot be activated or even used. However, the dual-head USB-C cable is basically All of them support PD.
When buying a charger, try to buy one with a USB-C interface instead of one with a USB-A interface.
2. Charging power, 60W, 100W, 240W are all IQ taxes.
The maximum power of the iPhone 15 can reach 27W, but in fact the stable power is around 19.5W. If you buy a 240W power charging cable, the maximum power is 27W.
The most common USB-C cable can also support up to 27W, so don’t think that the higher the power, the better. In fact, the higher the power, in addition to being more expensive, the wire diameter is also larger, thicker, harder, and difficult to store. All are shortcomings.
Of course, if you also want to consider your Macbook and your notebook also use this cable to charge, then if I didn’t say it, it probably needs to support 100W. It’s just for Apple 15, so you don’t need to consider the charging power.
3. Transmission speed is very critical, so special attention should be paid here.
The transmission speed of iPhone15/iPhone15 Plus is USB2.0 specification, with a maximum of 480Mbps, and the actual transmission can reach about 60M/S.
The transmission speed of iPhone15 Pro/iPhone15 Pro is USB3.2 standard, with a maximum of 10Gbps, and the actual transmission can reach more than 1000M/S.
In my opinion, more than 90% of the so-called iPhone15 data cables currently sold on e-commerce platforms are USB2.0 cables. If you don’t believe me, take a look at the final transmission speed. It is either not marked or has a hidden version of 480Mbps. , this is USB2.0.
If you hold the Pro series, be sure to buy one that supports USB3.2. Do not buy one that only supports USB2.0. Data transmission is much faster. This does not affect the charging power, but it will affect the synchronization of data between you and the computer. Remember! !
My suggestion is that even if you get an iPhone 15, although its speed only supports USB2.0, you can also buy a USB3.2 cable directly. The price is about the same. Why not just get it right in one step. After all, the USB-C cable can also be used for many other things. As for the occasion, most mobile devices currently support USB-C cables. It is of course better to buy USB3.2 ones.
4. Does the data cable need to have an E-marker chip?
You will see that some high-end data cables will say that they have an E-marker chip. If you are only using them to transmit data or charge iPhone 15, it will not matter if you use them or not.
Without the E-marker chip, the charging current can only reach 3A, up to 60W. With this chip, it can support higher power, such as 5A, 10A, etc., and then the power reaches 100W240Wt, but if it is only for iPhone15 In other words, there is no need to consider the E-marker chip for charging.
In addition, the data cable of the E-marker chip can also be used to transmit video information. If you are considering using the iPhone 15 phone to connect an external monitor directly with USB-C, then you should buy one with an E-marker chip, so that you can directly project the screen output. , if you don’t have this usage scenario, then don’t use the E-marker chip.
- data cable
To sum it up:
- If you want to get it right in one step, just buy a double-ended USB-C cable with an E-marker chip that supports USB3.2 and above specifications (speed 10Gbps or above).
If you don’t have video transmission needs, then you don’t need an E-marker chip. Just buy an ordinary double-ended USB-C cable that supports USB3.2 and above specifications (speed 10Gbps or above).
If you basically don’t use it to transmit data, just for charging, then the most common double-ended USB-C cable will do.
Finally, I would like to remind everyone that the USB-C charging cable provided by Apple only supports the USB2.0 specification. Whether it is the iPhone15 Pro series or the entry-level iPhone15 series, the cables provided are all USB2.0 specifications. Apple is really smart. .
