The VooPoo TPP X vape tanks are easy to refill. Simply use the release button on the side of the pod, to reveal the e-liquid inlet. The mesh build of the coil means that e-liquid heats up more evenly and the overall flavour is improved. As both coils are made for sub ohm vaping, we’d recommend that an e-liquid with a 70% VG concentration or higher is used for best results. You’re also able to choose a tighter or looser draw with the adjustable airflow, so you can find an inhale feel that you prefer.
