Whether you choose draw or button, a little prep goes a long way. Charge your device fully the night before—nobody wants a dead battery at the gate. Clean the connection points with a cotton swab if you've been using it daily. And if you're carrying a spare cartridge, keep it upright in a protective case.

For button-activated devices, check your temperature settings before you head out. Set it to a lower wattage if you're new to the device, so you don't get a harsh hit when you're in a hurry. For draw-activated, just make sure the airflow isn't blocked and the mouthpiece is clean.
