I also travel and have managed to consolidate my power needs on a single Anker USB C + 4 USB A brick, albeit with a 12” MacBook on top Spec. Decided to optimize for weight and practicality on the road.
It is an awesome setup. Period.
I just carry an extra iPad block to loan to people who request to borrow a charger.
The 39W Anker brick does pretty well charging the MacBook, iPhone, 2nd phone, and a couple of Anker batteries (10K and 20K) at once. Only got a bit hot when I also threw an iPad instead of the 2nd phone.
