The Ailia Bottle is travel friendly in the sense that all you need is the bottle and the charger to use it (no microwaves or kettles). Before travelling overseas or domestically via plane you must contact your airline and get confirmation from them as all airlines have different rules and regulations. You must also take into consideration the power voltage of the destination country as some outlets may not be able to support our power wattage. Also, you will need a plug adaptor for your destination country as our charger has an Australian plug.
