Morning guys, I bought a OBS a while back, love the tank for no other reason than it will not leak and is easy to build, when I bought the OBS I got two Clapton coils with it, I use a joytech evic Vtwo mini 75w as my everyday, I vape at around 20 watts .3/.4 ohms and I get everything I need from the vape and the battery last around 8 hours before a recharge, the thing is the claptons are sitting there screaming use me... not sure what the build of the claptons is but want to know what wattage I would need to fire these things up they look huge, and is the Evic up to the job..
