Jokes aside, what the hell "single smartphone charger" means? Only one type of port (usb c) in smarphones? Or only one type of charger (for example 5V & 3A)? Or what? Poor choice of words.
This is why Apple just announced their new iPhone 15 with a USB-C charging port. They're standardizing and getting rid of the lightning cables, because the EU forced their hand.
Now you can buy any USB-C cable for your iPhone, instead of the overpriced garbage cables they forced you to use previously.
