Lots of trouble with Protank mini and ego twist getting dry hits. Please help.

[mr Z]

I've got a Chinese knockoff of the ego c twist and a kanger protank mini 2. To start, I know the twist is not the issue because I have tried my friends VV battery and the problem persists. I purchased the protank mini from the same site (fasttech.com) and while the site said it was authentic, I am not sure I trust them. (I also purchased kanger coils labelled as authentic and I'm pretty sure they weren't.)

Anyways, I've now got authentic Kanger 1.8 omh coils (Purchased from discountvapors.com so I assume they are trustworthy) and I can't go above minimum voltage without getting a serious burning taste. At 4.0 volts I get burning within 1 or 2 hits, I've tried this on 3 coils. Yes, I've tried turning the plastic caps on the coils upside down.

So, do I have a bad/fake protank, or is it normal to not be able to run 1.8 omh protank coils at 4 volts? What should I do?

I have found you can't go past @ 3.8v on a stock 1.8 coil. This is all a matter of taste though. Also a matter of what type of juice you are using. PG/VG ratio for example

What kind of PV/VG ratio should I be looking for to run a higher voltage?

Also what else should I look for in my juices to be able to get more smoke? I feel raising the resistance to be able to raise the voltage is just going to leave me with the same amount of smoke. Correct me if I'm wrong please.

The girlfriend has went thru about 10 bad pro tank replacement heads in about a week so I don't know if there has been a bad batch or what but this is the first she's ever had trouble with them.

on a twist, higher resistance coils are what you will want to burn at hotter/higher volts. You could use any ratio of juice really but thicker juice might gunk your coils quicker, thicker can mean high vg or a lot of sweetner (darker juice). I find higher vg gives more vapor but higher pg tends to give more flavor. lower volts will make the vape cooler than high volts though.

i got a lot of dry hits using the stock coils. rebuilding fixed that.

I actually like lower resistance on my ego style batteries with lower voltage. Battery lasts a little longer. I have also been getting a lot of dry hits with my stock kanger heads lately. I found re wicking them with cotton solved this problem for me.
A dry hit and a burnt liquid hit are two different things. A burnt liquid hit means the voltage is too high. A dry hit means your coil head isn't wicking properly or you're not allowing enough time between draws for the wick to draw in more liquid. As I mentioned, I have had several over the past few weeks that weren't wicking properly.

I'd aim for 5 watts.

for 1.8 ohm
v squared = 5 x 1.8 = 9
v = 3 volts


at 4 volts, your power is : 16/1.8 = 8.9 watts. Ya, that would be high.

More vg gives more fog, but more likely to burn; I suggest experiment with 50/50 and vary from there.
