I am fairly new to vaping. My friend gave me his old starter kit after he upgraded a few weeks ago. I quickly upgraded the stock tank to an aerotank mini, I like the airflow control. So everything worked fine until last night. I opened the tank and topped it off (only about half empty). When I closed it back up and waited a couple minutes it tasted really burnt. So I thought maybe its the coil going bad and replaced that. Still burnt, so I read up on priming coils, which seems to be a bit more for top coils. I played around with a few things and go no new results.
So I went to the vape shop this morning. The guy tried my tank on his battery and it worked fine. Back onto my battery it was burnt after 3 draws again. So he suggested that the battery was misfiring and boiling rather than vaping the liquid, or I think more likely overpowering and burning the coil faster than it can wick. So I got a new battery, something I was meaning to do anyways. I grabbed a Spinner II VV battery and tossed the aerotank mini on it. It worked fine for a while. Then all of a sudden, burnt again.
Back to the internet, I replaced more coils from a different pack. I went back out and grabbed an aerotank v2, also something I've been wanting to grab recently. I lowered the voltage, cleaned battery contacts. Anything I could find online basically. Nothing worked. So I called up the shop, he suggested the coils were duds until I explained that they were from different packs and they all did the same thing. At this point everything within the device was replaced and brand new. Tank, coils, battery. The only thing the same was the juice. It is a 50:50 PG:VG, 1.8mg blend that I got locally. He said that it could maybe be a bit too thick so I cut a tank full of the juice with a few drops of pure RO/DI filtered water. Still no change, plus I used about 1/3 of a 30ml bottle with no issues. So now I'm just frustrated and almost out of ideas.
I still think it is a wicking issue though. Everything in the device is brand new and replaced. When it sat overnight it worked briefly in the morning before being burnt again. I am give ample time in between draws for the coil to cool. My last idea is to try a different juice, I have one here that I'm not overly fond of but will test it just to see if it helps. I still would like to know the cause though if that does do the trick.
