What you have should work. It might take a while before you can taste milder liquids . I agree on the spares ,you should have two or three batteries and if using disposable clearomisers or cartomisers you should have as many as you can afford. If you switch to a atomizing device with changeable coils as suggested you still need a spare device and as many extra coils as you can afford. What you have should last from a week to a month but you just never know. On your battery you can use any atomizing device for Joye Ego,306 or 510 and that is quite a lot of different atomizing devices. Look at Vaportalk store ,Eliquid Market, Ecigbestsave, Litecigusa or Madvapes for atomizing devices,batteries and eliquid and you should be treated fair.
