MacBook Pro USB-C Charger Not Working? Here's What You Need to Know

Are you experiencing issues with your MacBook Pro's USB-C charger not working as expected? If so, you're not alone. In recent times, there have been concerns about the compatibility of certain chargers with Apple's latest laptops. Specifically, some users have reported that their MacBook Pro's USB-C ports are not supporting fast charging via USB-C to USB-C cables.

So, what's going on here? According to a Reddit post by USB-C engineer Benson Leung, there isn't yet a USB-C to USB-C cable that supports the Extended Power Range (EPR) standard. As a result, fast charging is currently only available through Apple's new MagSafe 3 port. This has left many users wondering why their MacBook Pro's USB-C ports are not capable of supporting this feature.

The reason behind this limitation lies in the fact that Apple's implementation of the USB PD 3.1 EPR standard is limited to 28v, which delivers up to 48V at 5A, supporting a maximum power output of 240W. This means that only chargers that support this standard can take advantage of fast charging.

In recent news, Apple released its new 16-inch MacBook Pro charger, which uses the USB PD 3.1 EPR standard, making it the first charger on the market to do so. This development is significant because it allows for power delivery via USB-C cables at up to 100W.

The history of USB-C charging standards dates back to when the USB-C Power Delivery (PD) standard was developed. This specification supported higher voltages needed for fast charging, but the new 16-inch MacBook Pro models do not support this feature. However, Apple's involvement in driving the development of the USB PD 3.1 EPR standard has paved the way for faster charging capabilities.

If you're experiencing issues with your MacBook Pro's USB-C charger not working, it may be due to the lack of compatibility with the new USB PD 3.1 EPR standard. Unfortunately, this means that fast charging via USB-C to USB-C cables is currently unavailable on these devices. However, Apple's implementation of the MagSafe 3 port provides a workaround for those who need faster charging.

In conclusion, the MacBook Pro's USB-C charger not working issue is primarily due to the limitations of the current USB-C to USB-C cable standards. While this may be frustrating for some users, it's essential to understand that Apple is actively developing new technologies to support faster charging capabilities. With the release of the 16-inch MacBook Pro charger, we can expect to see more advancements in this area.

In the meantime, users who require fast charging should consider using alternative charging methods or exploring other options for their specific needs.
