The mvp 2.0 uses Ohms law to find the resistance + your desired wattage to apply the correct voltage to the atomizer. But to say it has step down No it dose not.
Let me get a little more detailed as well. That may help provide an answer better. I would still consider myself new to
vaping as I haven't branched out much. I had a clk 1280 and that seemed to work great. died on me. Bought an istick 20w and I blow through three times a much liquid and a ton of burnt hits with a fully charged battery. This prompted me ot jump on the net and see what people say bout the I stick as im only
vaping at 3-4v, which is a lil strange in the first place to be getting burnt hits at that voltage. This prompts me to get online and do some research. low and behold, I find the problem. Others have had the same issue due to the Istick not dropping down the voltage (like they claimed it did) when it was charged to a higher voltage than I wanted to vape. It vapes at the max voltage till the battery is drained enough to have to step up to my voltage. I want something small, so my options are Istick 30 or something in the mvp line.
