I'm going on vacation next week and would like to take minimal supplies. If I charge up all my batteries before I leave will there be a chance that one of them will still work if the other goes dead? (I plan to take 4 plus a charger). I will be in vegas and there will be a change a I won't have access to be able to charge if I'm out and about for a full day. I don't have to sit in my room for 4 hours waiting to charge a battery! Taking 3 pen style and my eGo-T. Thoughts?
