Sub Ohm Tanks
Sub Ohm tanks like the Kanger Subtank Mini are more similar to oversized bottom coil vape pen tanks. The Kanger Subtank Mini holds 4.5 ml of eliquid. They are very easy to operate as you just need to unscrew the base of the tank to refill it with a high VG ejuice or to access the oversized wick. You can use disposable wicks or switch to the rebuildable atomizer deck and build your own coil. Sub Ohm tanks work well with 30W box MODs like the iStick and IPV Mini.
