The rumors continue to abound as to whether Apple will include a USB-C to Lightning cable to function as an 18 watt fast charger with the upcoming iPhones this fall. The current consensus is that fast charger options may be somewhat limited because Apple is requiring USB-C authentication compliance for the charger and cable.
Per supply chain sources, third-party device makers can still make iPhone chargers, but only those that are comply with the USB-C authentication standard for power can support fast charging. That means even though non-certified chargers may offer 18 watts, the iPhone will likely draw just 2.5 watts.
Apple is apparently also requiring that USB-C to Lightning cables support the USB-C authentication standard, too. Without the right charger and cable combo, it looks like you won’t get 18 watts charging no matter what the device maker advertises.
As usual, Apple is expected to debut its next-gen iPhone in September. Previous rumors have stated that the new handsets will include a USB-C to Lighting cable, a USB-C charger, and may ship with three iPhone X-style screen size options.
The authentication requirement is currently seen as a method of quality control, as a shoddy power adapter could damage the handset’s battery life or possibly help cause a fire.
Stay tuned for additional details as they become available.
