Our TerpPens PowerPen delivers as a Li-Ion battery with full 420mAh more than enough energy to use our inhalers continuously in everyday life.
The TerpPens PowerPens are activated solely by the draft of air during inhalation - without waiting and without pressing a button - thanks to the practical Airflow function.
The scope of delivery includes a practical USB charger onto which the TerpPens PowerPen is simply screwed on during the charging process.
