iStick 50w will default to 20w with Valyrian tank

[abstruseoni]

I'm trying to use my old iStick 50w with my Valyrian II. But as soon as I screw in the Valyrian, my iStick instantly changes to 20w. Does anyone know why? Typically I don't go above 15w with my Voopoo tank. And when I'm priming a new coil, I usually start around 6w and build up to 15w. I don't want to kill a new coil by hitting it with 20w, but the iStick won't let me go any lower while the Valyrian is attached. Any thoughts?

-Update-
So apparently Valyrian tanks should run around 90w? And using only 20w will feel like hitting a Voopoo tank at 6w.. I'm steadily increasing the watts and it's hitting great

Hi bro, yes, the coils that come with Valyrian tank are rated at higher watts. Because the lowest output voltage for Eleaf iStick 50w is 2V, if using a 0.15ohm coil with iStick 50w, the lowest output wattage is around 26W (according to the formula P=U²/R, "P" represents "Power(Wattage)", "U" represents "Voltage", and "R" stands for "Resistance"). So the iStick 50w won't go lower.
