These are the specifications on the PnP-VM1 coil.

The juice you are using is a factor for coil longevity, some commercial juices are very sweet and will go through coils quite quickly.
You might want to try a PnP-M2 as it's only 20 to 28W, it will go through less juice but have a tighter draw than the VM1.
If you are looking for a tighter draw still, the PnP-R2 is a 10 to 15W coil designed for MTL vaping.
