8 to 10 watts on an istick 20 may be a little high. I usually run around 7.5 and sometimes lower on the 20.
+1 on the above. The iStick 20 ran hot, especially on the lower end of the scale. Never had a iStick Mini, but as I recall it fires the same as the 20. (You can read about the Mean vs. RMS power calculation thing in the iStick thread - or watch pBusardo's youtube vid review on the iStick 20.)
I now use my 20w only as a back-up device - which means "hardly ever". It became too much of a hassle trying to get the same vape when switching between the 20 and other devices.
However, I just took off a GS-Tank from an iStick 30w and put it on my 20. Somewhat of a subjective observation, but to me the 20 running at 7 watts produces more vapor than the 30 at 11 watts. Really a nice vape, but like I said it was too much hassle when switching between devices. It's been awhile, but as I recall I usually ran it at 6.5w.
Caveats: Running a rebuilt 1.5 ohm coil in the GS-Tank and only have 50/50 PG/VG ratio eliquids.
It is the same other than the mini suffers from .5 intervals in wattage and only dips to 8 watts and no less.Yeah, I remember the MEAN voltage issue with the OLD 20 watt, so I waited and bought the iStick 30 watt, gave it away. I just got the newer MINI 20 watt, tiny version, and maybe it suffers the same problem.
Which coil are you using?I have the 20w now and ms air and couldn't get a coil to last a full day. I noticed my son runs his device on volts with long coil life. Sooooo I put in another new coil changed my device to volt and three days later I'm still on that coil. The tank doesn't get as warm and my juice is not turning dark. Don't know why this works because I'm running 4 volts which is higher than the 7-8 w I was running. Just wanted to share what is working for me.
1.5 coil 50/50 juice but I did run one tank on it at 70.vgWhich coil are you using?
The 1.5 handled my DIY 100% VG just fine, but couldn't go above 8 watts on the 30W.1.5 coil 50/50 juice but I did run one tank on it at 70.vg
