If you've been vaping for a while, you already know that airflow affects everything—from flavor to throat hit to vapor production. An airy draw tends to produce more vapor and a cooler hit, but it can also make the e-liquid finish faster if you're not careful.

To stretch your device on a tight budget, focus on technique. Instead of long, deep inhales, try shorter puffs with a pause between them. This gives the coil time to re-saturate, so you don't get dry hits that waste e-liquid.

Also, consider the weather. Spring temperatures are usually mild, but if you're outdoors a lot, keep your vape out of direct sunlight. Heat thins the e-liquid, which can cause leaks and faster consumption. A pocket or a small case is a good spot.

Finally, check your airflow settings. If your device has adjustable airflow, you might want to close it slightly on windy days to avoid losing vapor to the breeze. It's a small tweak that can save you money over time.
