The Revvo by Aspire is an awesome leak proof tank.
We carry one type of replacement coil for this tank. These replacement coils will vary in resistance from 0.10ohm to 0.16ohm. The effective wattage range on these coils is pretty substantial, due to the leak-proof nature of this tank. We have seen people successfully operate this tank anywhere from 50 to 100 watts.
These coils tend to last for around 3 to 5 days with normal use.
Note: It is worth mentioning that the Revvo requires the user to tilt the tank on a regular basis to saturate the coil.
Revvo Arc coils are sold in a pack of 3.
