Yes you can, it's the coil inside that makes the difference, not the tank it's self. But on most mech's you will need to use a 510 adapter with skirted tanks, like evods, and they do look a bit silly.
What you do need to watch out for with mech's, if you haven't used them before, is for when the battery gets low. As there is no warning lights, like a vari volt/watt mod, to tell you the battery needs a recharge.
