Having the Kangertech Subtank, Aspire Triton, Uwell Crown, Freemax Starre Pro, UD Zephyrus, UD Goliath V2 at home, the SMOK TFV4 blows them all away. This is definitely no tank for low-wattage mods. Everything that can handle above 80W is perfect. The triple coil is a cloud chaser with good flavor, the quad coil a still blows huge clouds with tremendous flavor.
This thing sucks juice like I never saw before with another tank – so better do your own juice and don’t use the expensive premium ones. Otherwise you will easily spend $30 a day just for juice.
A real con are the really crappy o-rings. So take care of them – especially because there are no spare o-rings in the package. The full kit comes with a triple and a quad coil, the single RBA deck and a spare glass tank.
There are a lot more coils coming (all the coils are HUGE). For example a sextuple coil, several TC nickel coils and the one I am looking forward the most: a titanium coil (for TC too of course).
Let’s see if my excitement holds up for the next few days. Currently this is the strongest buy for a tank I could express.
About stepdown: You might have noticed or read in several forums that the IPV D2 does NO stepdown in power mode. This means that it puts out always at least the nominal battery voltage. In case you have a .5 ohm coil and set it to 7W, the Mod will show around 1V but in fact there are >3.7V.
This is a bummer for low wattage vapers as well as for proper breaking in coils. But there is a workaround:
The D2 IS capable of stepping down in Joule (Temperatur control) mode. It switches from DC to PWM there. So take your kanthal build, switch to TC mode, set the Joules to your desired wattage (Joules = Watts with YiHi chips) and just to be sure: maximize the temperature.
Temperature protection will not kick in as kanthal does not change its resistance.
Originally the confusion was there because most shops just stated “Output voltage: 1.0V-7V”. In fact it is:
Output voltage: 3.6V-7V (Power mode)
Output voltage: 1.0V-7V (Joules mode)
Maximum resistance in TC mode should be .3 ohm. Tests show that the mod does not bother at all. You can vape your .5 ohm builds in TC mode as well and so far it has not kicked out of TC.
Pioneer4You fixed this now – but not for the D2 but with the release of an updated IPV D3.
