Problem with USB-C mobile battery charging backwards on iPhone 15

Apple changed the port on the iPhone 15 series to USB-C this year, allowing the use of USB-C cables and existing USB-C compatible mobile batteries. However, we have found that some USB-C compatible mobile batteries are not working properly and are experiencing charging issues (MacRumors).

According to information provided on Reddit and MacRumors forums, this problem is caused by the reverse charging feature in the iPhone. Not all existing USB-C mobile batteries are compatible with the iPhone 15 series, causing the iPhone 15 to fail to charge or, in some cases, the iPhone 15 to charge the mobile battery.

Various mobile batteries are affected, although it is not possible to list the models that do not work. Users who contacted Anker about problems with the nonworking product, the Anker PowerCore Slim 10K PD, were told that they could only use the USB-A port to charge the iPhone 15.

It seems that due to the iPhone 15 series’ reverse charging function, the USB C’s port charging of the Anker PowerCore Slim 10k PD The only way to get your iPhone charged is to use the USB A port.

The only way to get your iPhone charged is to use the USB A port.

Anker will do more tests on all of our power banks to see if this is the issue with certain power banks and try to get a solution.

What is the E-Marker chip?
The USB-C charging cable connector has a chip called an E-Marker (Electronic Marked Cable), similar to the charging cable’s security ID card. This is actually a protocol controller feature that monitors the charging status and helps to properly allocate the current.

Most USB-C charging cables on the market today have specifications of 3A and 5A. According to USB-IF Association regulations, if the current output of the power adapter exceeds 3A (100W) or 5A (240W), an E-Marker chip must be incorporated to ensure that charging occurs under a safety protection mechanism. The following table distinguishes these E-Marker cables according to various parameters
