A vape tank is an essential component of any high wattage vaping device, such as box mods and nearly all sub-ohm vape mods. Vape tanks are usually screwed onto the base of a vape mod, which then supplies heat to the coil within the tank responsible for vaporizing the vape juice that is contained in the tank. Vape tanks come in myriad of different sizes, types, base diameters, and liquid capacities, allowing for greater flexibility of choice when pairing with a compatible vape mod.
A tank will typically be attached to a mod via a 510-threaded connection that's as simple as twisting on. Vape tanks house a coil that can be screwed onto the either the base of the vape tank or the chimney section, which is made of cotton and wire. Once the coil is fastened and glass piece secured, vape juice can be squeezed into the tank from a filling port located somewhere on the tank (usually the top, where it can be uncovered). The cotton will take a few minutes to wick the vape juice, but once fully saturated you can start vaping!
Most tanks will also have some sort of air-flow control, which can be adjusted to personal preference. As a rule of thumb, more air means cooler vapor production, whereas more restricted air-flow will product a warmer vape.
The standard across the industry, sub-ohm tanks are usually large in capacity, and use coils that have resistances of less than 1.0ohm (although typically lower and as low as 0.10ohms). Sub-ohm tanks like the Uwell Crown 4 are great for beginners.
Mesh coil vape tanks utilize mesh coils, which offer incredible smoothness and flavor production, while still maintaining satisfying cloud production. Traditional coils use wrapped metal wiring to heat surrounding cotton, but mesh coil designs create a more even heating surface area that is responsible for their fantastically smooth output.
Clearomizers are simple tanks that are disposable after the cotton has run its course, as they have a wicking element built into them that cannot be replaced.
