I've also had one of these tanks hooked up to an istick mini and it works great. On paper, the istick mini cuts out at 10 watts, but using an inline 510 meter, I've read my setup at about 13.5 watts, steady with the 1.6 ohm coil at 5 volts. Performance was top notch and just about as good as the istick 30 at 17 watts. 15-20 is about as far as you will want to go with this tank, but 16 or so seems to be the sweet spot. That said, the mini istick at 13.5 watts performed GREAT with the tank. And the setup was teeny tiny at 113 mm with the stock drip tip. Use a slightly shorter one, and it'll be even smaller.
