A vape tank is the part of your e-cigarette or mod that holds your e-liquid and contains the coil which vaporizes it. In most devices, the tank sits on top of the battery. Which is the pen-like part on older designs and the bigger, usually box-shaped part on modern devices.
Tanks are usually cylindrical in shape, with glass bodies and a metallic top and bottom section. They have a stem running up the centre, which is attached to a coil at the bottom and leads up to the mouthpiece. The main function of tanks is to allow the liquid in the tank section to soak into the wick, which makes contact with the coil. When you activate your vaping device, the coil heats up, vaporising the liquid in the wick. The tank then replenishes the wick with liquid and you can continue vaping.
There is a perfect vape tank out there for everyone. Here are the best vape tanks in each device to help you find exactly what you are looking for.
