Following advice from other members, I bought 2 Kanger Evod's. however, whenever I use them. I get decent throat hit but very little vapour. My batteries are 3 900 mah and power up my other clearomisers easily. The Evod's came withh a note advising that they need 4.2 to 4.4 volts from a battery. What voltage do normal batteries supply and what battery should I get to drive the Evod's.
