The Nexmini uses nexMESH replaceable coils that are specifically made for it. This means that they aren’t cross-compatible with any of Wotofo’s other coils. The Nexmini comes with the following two coils which are the only coils presently available:
1 x nexMESH M21 0.6ohm Parallel Coil (15-25W)
1 x nexMESH M22 0.6ohm Coil (13-20W)
Interestingly, even though these coils are the same resistance, they have different wattage ranges. The M21 is rated for 15-25W and best from 18-22W. The M22 is rated for 13-20W and best from 15-18W.
