Can I carry my VocalMist on flights?Updated 2 months ago

There are no issues flying with your VocalMist, both in checked or carry-on baggage. 

VocalMist uses small, non-removable lithium-ion batteries (2.4 Wh). Travel restrictions only apply to much larger lithium batteries.

You will be glad to know that it is also fine to bring your Hydration Formula capsules in your carry-on baggage.

For both domestic and international flights, TSA's rules permit liquids to be included in your carry-on bags, so long as each liquid vial is under 3.4 ounces (or 100ml), and the entirety of your liquids are placed in a quart-sized bag. Hydration Formula units are each only 5ml, easily passing this requirement.

To avoid confusion, you can carry your capsules in the original box (featuring ingredient information), and/or put your capsules in a plastic bag to expedite the TSA process.
