At the end of the day, give your device a quick wipe down. Then store it in a cool, dry place—not in your car, and not on a windowsill where it'll bake in the sun. Spring temperatures can swing, and extreme heat or cold can affect the battery and e-liquid consistency.

If you have a protective case, use it. Disposables are durable, but they're not indestructible. A case prevents accidental drops and keeps pocket lint out of the mouthpiece.

Before you close up, take a few puffs to check performance. If something feels off, troubleshoot now rather than discovering it tomorrow.
