NPET UC10 USB C Wall Charger 20W Black
That changed with the release of the iPhone 12 series, which didn't include headphones or a power adapter in the box -- only a USB-C-to-Lighting cable. And the same is true for the new iPhone 13 models.
NPET UC10 is literally the size of old Apple's 5-watt USB charger that offers 20-watt charging. Featuring PD 3.0 technology, it charges more than 2.5x faster than that 5-watt charger (with a USB-C-to-Lightning cable). It's less than $11.99.
