Apple is rumored to bundle an 18W USB-C charger with its 2018 iPhones. While that’s certainly good news, the company is reportedly planning on clamping down support for counterfeit and low quality third-party USB-C chargers.
As per Mac Otakara, third-party USB-C fast chargers will require USB-C Authentication or C-AUTH so as to allow them to fast charge 2018 iPhones at their full 18W speeds. If not, the charging speeds from them will be limited to a mere 2.5W, with a warning being displayed on the iPhone’s display as well.
USB-C Authentication chargers are built to spec, and the certification is a good way of knowing that a USB-C charger is going to work properly with your device and not fry its circuitry.
Apple is a key member of the USB-IF (Implementers Forum) so its implementation is going to be the same as the standard that has been widely adopted by the industry.
This is in no way a bad move from Apple and given how widely counterfeit USB-C cables and chargers are available in the market, the company is just ensuring that its 2018 iPhone owners remain safe from them. Hopefully, existing USB-C chargers from reputed brands and other OEMs should also work properly with 2018 iPhones and charge them at their full 18W capacity.
