This is a replacement pod for the Innokin Podin vape kit. Not compatible with other models. This pack comes with one Podin pod and two Podin coils (one spare, one pre-installed in the pod). The coils have a 1.3 ohm resistance. The capacity of the pod is 2ml. To refill, simply lift the silicone stopper and fill with your choice of e-liquid - we recommend using e-liquids that are at least 50% PG.
