iPhone 15 will charge your watch and airpods from the back of the phone, so you don't even need to travel with the watch charging cable anymore.
Samsung did this already (branded as "PowerShare") so it's the year of iPhone catching up on charging features.
I am surprised apple hasn't included this ability yet. My pixel 6 pro also has this ability.
I was also really hoping for wireless "MagSafe-out" charging for the Apple Watch, which would come in very handy when traveling – often there's limited outlets on hotel nightstands, and sometimes I just forget the watch charger.
If I'm traveling with a computer too I use a 2x USB-C wall wart to fit everything in one plug. Not perfect, but beats the rat's nest of cables that it replaced.
Since the Qi charger isn't MagSafe it doesn't really work for topping up the phone from the battery on the go, so I often end up tossing a short Lightning cable in my bag anyway. Will be nice to have USB-C eventually and not worry about that (but I intend to drag this iPhone mini out for a good 5 years).
