Hello, everyone, this is my very first post here, so if I am posting in the wrong section let me know. So I am really new to vaping and have never vaped before, I have a SMOK Vape Pen 22. I opened it up today and decided to try and inhale but when I did it ended up leaking, and almost got into the charging port. I'm not sure if it did or not but I tried my best to keep the liquid from getting into charging port. I found out that the pen was not actually charged so I decided to put it on charge with the USB cable they gave me and I had to use my own power brick of course. But I noticed after a few minutes the pen started to get really warm not hot but just really warm the tank got warm and the battery. I was told this is fine as long as it's not hot. So I just want to confirm this here to see if this is actually normal, I should be under warranty so if anything I can always see if they can exchange it for me.
