Aeroshot Pure Energy is a slim, pocket-sized tube that works like an asthma inhaler. Puff gently, and the tube releases a light powder that dissolves instantly in your mouth. Each Aeroshot contains 100 milligrams of caffeine, roughly equivalent to a tall mocha at Starbucks. Unlike a Starbucks mocha, it’s calorie-free, and it won’t give you horrid coffee breath. And unlike your average energy drink, it meets TSA regulations. Though personally, a big jolt of caffeine is the last thing I want when I’m boarding an airplane.

AeroShot will be available in Boston and New York in January.
