The center pin in my iStick 100w is pinned down, when screwing in 0.30ohm atomizer, it starts jumping at between 0.31 to 0.34 thus making unstable WW.
Even the slightest touch makes the ohms to start jumping around.
Is there any way of straightening the center pin?
It's spring loaded.
My battery is dual Sony US 18650VTC4 30A 3,7V 2100mAh.
