The pod attaches easily to the top of the device through a strong magnetic connection. However, it can be easily removed when you need to fill with e-liquid. The filling port is on the base of the pod. To fill push the nozzle of the e-liquid bottle down onto to inlet. This will allow you to squeezed the liquid through the seal while it is pressed down.
Both coils are designed for mouth to lung vaping but use different materials.
The 1.0ohm pod uses a mesh coil. The mesh makes contact with more liquid so it can heat up a larger amount to create a thicker cloud of vapour. It also activates quicker.
This pod uses patented ceramic tech for a more stable and durable vape. Within the wicking material are small holes that allow the heat to be be passed through a large amount of liquid to create a fast-acting cloud of vapour.
