A switching power supply. The switching transistors are gallium nitride,
which allows for higher switching frequencies (at pretty low losses) and
thus for smaller inductive components and smaller packages. This makes
for surprisingly small power supplies

But they'll only help you if you find a mains outlet -- many public transport
vehicles and places (rail stations, e.g.) in our area do have USB-A charging
sockets but no mains. Which kinda makes sense.
