Hi. This is my first post. I've been vaping for just a few weeks now and enjoying the exploration, but there is just so much information to sift through! I'm hoping someone can answer a few questions.
I'm using a 650 mAh ego with a smok dc mega cartomizer, which I chose after doing a lot of research. I haven't had any problems, and have been loving it...until now. I got a new batch of sampler juices in the mail and after letting them steep for a while, I filled a new carto with juice just as I had with every other flavor/cart I have used til now. I did everything the same, but it tastes like burning electrical things smell, with some burnt sugar on top. Any ideas what caused this?
Also, I've read some conflicting things about the set up I'm using, re: dc mega cartos being bad for ego batteries. Can anyone clarify this using newbie speak?
And finally, is it bad for juices to sit in the cold, like in my mailbox when it's freezing outside? It's that time of year, and I have a few more orders on the way.
I have many more questions, but suppose too many might be inappropriate for this forum. Not sure of all the etiquette yet.
Thanks to anyone who wants to reply.
