Rechargeable Electronic Shisha. The 800 Puffs EVOD Shisha stick bridges the gap between those who are looking for a cost effective alternative to traditional smoking methods and the popularity of natural hookah flavours.. This disposable Electronic shisha pen is a battery-operated device similar to an electronic cigarette. It is powered by an atomizer which heats up an e-liquid comprising of water and fruit flavourings, vegetable glycerine and propylene glycol. Both propylene glycol and vegetable glycerine are non-toxic organic compounds and generally considered safe for consumption and turning it into a vapour that can be inhaled.
