When I travel, I'm usually going with an iPad, now 2 iPhones a watch and AirPods. Throw in the Pencil also.
I bought a travel charger/case for Apple Watch and upon getting it in the house, I knew I'd never use it. Way too big and bulky to suit my tastes so I use the lightning cables and standard issue puck that comes with Watch.
I do however take with me a 4 port wall charger and also carry 1 of the single standard issue Apple chargers because they're small enough and easy to use if you need to get power in an airport and well I paid for it!
This is is the 4 port charger I use.
