• If you've left a disposable vape in a hot car or drawer for weeks, summer heat may have altered its performance. A quick stress test—checking airflow, battery response, and flavor—can tell you whether it's safe to use or time to replace it. This guide walks you through the steps without any technical jargon.
• Heat can thin e-liquid and affect battery performance, so a visual and airflow check matters after a long break.
• A stress test helps you decide pass/fail: if airflow is blocked or flavor is off, don't force it.
• Store disposables in a cool, dry place—avoid leaving them in direct sunlight or a hot car.
