![]() This delivers up to 48V at 5A, supporting anything up to 240W. This new standard is known as USB PD 3.1 Extended Power Range (EPR). A new standard was developed to support power delivery of up to 240W, and Apple was instrumental in driving this. That was fine at the time, but with higher-powered laptops on the way, more power was needed. This allowed for power to be delivered via USB-C cables at up to 100W. When the USB-C standards were developed, there was a specific standard for charging, known as USB-C Power Delivery (PD). Update: The newness of the standard also means the USB-C ports aren’t compatible with it. The bad news is that the technology is so new that there isn’t yet a compatible USB-C cable. The good news is that it’s the first one on the market to offer a new high-power charging standard that enables USB chargers to exceed 100W for the first time. There’s good news and bad news about the new 16-inch MacBook Pro charger.
