Hello @dizin Sorry to hear about your troubles. With it coming back on for a spell, then it stop working again, sounds like you may just need to snug down one or both contacts inside the Nano. Could also be your cord going bad, but it could be an easy fix you at least could check. Be vaping tonight, if lucky. The two screws to access the innards are under the cork feet on each end of the Epicvape name on the bottom plate. Remove the bottom plate and check the snugness of the two contacts. The contacts are not soldered, they are car speaker type contact slides. Hopefully one of those has just slid off. First step in trouble shooting, couldn't hurt to check. And I'm sure @nadia_epic will pop in here shortly and you'll get sorted out either way. Good luck.
