I'm fairly certain that it's more involved than a simple firmware upgrade. The amperage and voltage limitations would have to be a hardware issue. It's probably a simple fix that will come in the next incarnation. There have been some minor complaints about the "enter" button as well. As it stands though, the eVic is probably one of the coolest PV's that has ever been introduced to the vaping community and you can be sure that any problems will be corrected. It amazes me how quickly the vaping technology is moving forward. When I first started, there were only a handful of "mods" out there and they were all strictly mechanical. In just the last year or so alone...Darwin, ProVari, The Buzz, The Joker, Saber Touch VV, Infinity, Diamante, Lavatube, Lambo, VMax, ZMax, Vamo...and many more are flooding the market. The eVic is the next evolutionary step and it won't stop there. I can only imagine what will be available this time next year! Sorry...I was on a roll!
