Use high-quality cables rated for the power levels required; for 45W charging use USB-C cables that support required PD wattage. For air travel, check airline regulations regarding battery capacity and carry the power bank in carry-on baggage if required. Regularly recharge the unit every few months if not used to maintain battery health.
