A phone connects maps, transport, translation and bookings. Prepare power before you need it.
Check the plug
Korea commonly uses round two-pin 220V outlets. Confirm your charger supports the voltage and bring an adapter if needed.
Carry a cable and power bank
Maps, transport and translation drain batteries. Keep a cable and power bank in a small bag.
Use café outlets respectfully
Outlets are not available at every table. Follow shop rules and keep cables out of walkways.
Avoid public USB ports
Availability varies. Prefer your own charger and cable, with a screen lock and backup.
Charge before the next move
Charge before long transfers, boarding or check-in. Offline maps and lower brightness also save power.
