Pack power banks in your carry-on, never your checked bag. If your cabin bag is gate-checked, remove your power banks and keep them in the cabin.
Make the gate check easy
Before boarding, put your power bank somewhere you can reach without unpacking your entire suitcase. If staff take your cabin bag for the hold, move the power bank into the bag you keep with you.
Protect the battery
Protect terminals against short circuits and keep the device safe from crushing or puncture. A protective pouch helps separate it from keys, coins and other metal objects. Never travel with a damaged, swollen or recalled power bank.
