There are two versions of this coil available; the UB Pro P1 0.15ohm Coil, UB Pro P3 0.3ohm Coil to suit each vaper's desired preference.

In addition, the UB Pro P3 coil is suitable for a power range between 60 and 70 watts. According to the manufacturer, the UB Pro P3 0.3ohm Coil can be used for vaping in the TC mode. The temperature recommended by the manufacturer is 260 to 290°C or 500 to 550°C. Both coils have a mesh structure and are used for DL (direct lung) vape.
