I am doing something wrong but can't figure it out. I bought my first MVP about a year ago. After a couple of months it stopped holding a charge...I'd plug it in when the amber light came on and even left it to charge overnight... but it had died . The supplier kindly replaced it at no charge. The same thing has just happened with the new one after only three months ! I have been using it with the supplied iclear 30. I am a heavy vaper, and I do tend to use the pass-through while charging. I've read other posts which indicate a problem with the charging port...but it's happened to me twice and that seems odd. These two were the original MVP, not the 2 version. I'm thinking of just buying an MVP 2 and hope for better results, but am afraid I might break that one too. Help ! Thanks.
