It depends on three things, the ejuice, the volts you have the battery set at and the ohms of the coil head in the clearomizer. A lower ohm coil head (1.5 Ohm or 1 Ohm) will provide more heat to vaporize the ejuice, but will drain your battery quicker. The blend of the juice, vg/pg ratio may affect the vapor, high PG juice will have less vapor than say a 50/50 blend which is ideal for Kanger protanks. If your battery is fully charged and you have a good coil head at 1.5 ohms, you should be getting ok vapor. Crank up the volts. As an alternative step, you can get an Nautilus Mini Tank with BVC coils (bottom vertical coils) to use on your Spinner for a while while you look at some of the other mods such as an iStick 20watt, which will have all the power you need and then some for the Nautilus and the Kanger Protank.
