I travel with work a fair bit to different countries, lots of different wall sockets, I like to travel light so I use my MBP charger (means I can fast charge iPhone/IPP/MBP) and I have a travel adapter kit so that means I take only the wall socket adapter that is needed (instead of another adapter to work with my UK 3 pins).
Then I have 4 cables all USB C -
Then I have 4 cables all USB C -
- to lightning for my iPhone X and Beats Pro
- to USB C for MBP/IPP (cable that comes with the MBP charger)
- to Apple Watch 0.3m (short so less cable to carry/mess with)
- to multiport AV adapter (just in case I have to present)
