Apple (AAPL) debuted its iPhone 15 and iPhone 15 Pro on Tuesday, bringing major changes to the company’s most important devices including USB-C charging ports and a higher starting price for the iPhone 15 Pro Max.

Pre-orders begin Friday, September 15, with availability beginning Friday, September 22. The iPhone 15 and iPhone 15 Plus start at $799 and $899, respectively, while iPhone 15 Pro and iPhone 15 Pro Max start at $999 and $1,199.

The most notable change to both phone lines is their new USB-C charging ports. Rather than using Apple’s proprietary Lightning port, all four phones come equipped with the universal standard. Apple made the switch to comply with a new European Union regulation that calls on electronics manufacturers to use USB-C in an effort to cut down on e-waste and make things easier for consumers.

USB-C is used by manufacturers across the spectrum of gadgets. The standard not only allows for fast data transfer speeds, but streaming video and universal charging, as well. In other words, you can use your USB-C laptop charger to charge your iPhone or your Nintendo Switch charger to charge your e-reader.
