List devices and ports
Write down every device, its port and whether it must charge overnight or during the day. This prevents packing duplicate cables while forgetting the one unusual connector.
Choose one capable wall charger
A multi-port charger can reduce bulk, but verify its power distribution with all planned devices connected. The smallest option is not automatically the most convenient if ports are blocked or tightly spaced.
Pack one deliberate spare
A second general-purpose USB-C cable is usually more useful than several random backups. Keep it in a different bag so one lost pouch does not remove every way to charge.
Check the destination
Socket shapes, voltage support and airline battery rules depend on the trip. A plug adapter changes the physical connection; it does not necessarily convert voltage. Read the labels on your equipment and current carrier guidance.
