DynaVaps are an innovation in the dry herb vaping market. Unlike most other devices, there are no batteries in the DynaVap. Instead you apply heat either with a flame or an induction heater to the VapCap, when it is up to temp it makes an audible click and you can start pulling!
Where you place the heat will dictate the sort of hit you will get from the device, with heat applied right up near the tip of the cap resulting in lighter, flavourful pulls with multiple hits from the chamber. Alternatively building the heat towards the base of the cap can give massive hits, and with practice a bowl can be cleared in one.
