Hello All, I'm new to vaping. I just purchased an aspire CF Sub yesterday & have a question. I'm ready for bed, but it's not fully charged. Do I leave it charge all night although I'm sure it will finish while I'm still sleeping? Or do I unplug for the night and continue in the morning? The man at the Vape shop I purchased it at said to let it die entirely before charging & let it charge entirely before unplugging.. Will over charging hurt it? I spent far to much money on it for me to already begin messing it up not even 24 hours since purchasing. Thank you in advance!
