Hi,
Most of the clips on Utube show how to fill a cart or cartomiser or even cartridge but they don't show the other end of the device.
Unscrew the cart from the battery and hold it (the cart) at arms length at eye level. If you can see the thread then it is a male thread and the battery has a female thread.
I am not trying to be rude or crude but the male fits inside the female.
