When traveling with multiple devices, it’s recommended to bring one large (10,000mAh or higher) and one small power bank, along with a foldable charging station and the necessary cables. Key aspects to consider for a power bank include its capacity, weight, and connection types, ensuring it complies with TSA regulations that require spare batteries in carry-on luggage and limit them to 100 watt-hours. For international flights, check airline policies, as most follow similar rules about carrying spare batteries.
