What to do: Leave a fully charged device in a coat pocket for an hour outside (above freezing, just cold), then check the battery indicator and take a few draws.
Success signal: A device that holds its charge and delivers consistent vapor in the cold is a keeper. If the battery drops drastically or the vapor feels thin and weak, that device will frustrate them all winter.
Lithium batteries dislike cold, and that affects performance. Adjustable-airflow devices often have larger batteries to support the variable wattage, but that also means more weight. Pod-style devices are lighter, yet they might need a mid-day charge if your recipient vapes heavily outdoors. Think about their routine: do they take short breaks outside or spend hours in the cold?
