Being fairly new to vaping, some things just confuse me and this is one of them...Yesterday I went to my B&M store and tried the new leaf istick 30 watt battery and found that the vape at 6.8 watts was airy and lack luster. Now I used those numbers because that's where I vape on my eleaf iStick 20 watt. The 30 watt read my atty correctly (1.9 ohms), volts, registered the same (3.5 volts) but I had to jack the thing up to 10 watts to get the same vape as my 20. Any idea what may have been going on?
