So, recently received my NEXGEN Style 2 Ego battery with a variable voltage/LED display. Today, the display stopped working and is stuck on 3.8v. I tried messing around with the '+' '-' buttons but it doesn't change on the display... Now, I fear, that the voltage is too high and might be burning my artomizers. Currently, I have an off-brand CE4 (bought it from the local gas station) with 1.5 ohm wicks and an iClear 30 with 2.1 ohm wicks. Is there any way I can tell what the voltage is at? I've been putting it up to my ear, listening to the sound but am not too sure of what I'm doing. I'm new to vaping. The voltage range is 3.0-6.0. I've already contacted NEXGEN about the problem...and am awaiting a reply. Thanks.
