Vape Tanks Category Page FAQ

A vape tank is the part of your setup that holds e-liquid and houses the coil. It screws onto a mod or device, usually via a standard 510 connection. Inside the tank, cotton wicks soak up the liquid, and the coil heats it when you press the fire button. Tanks are refillable and use replaceable coils, so you can keep the tank and only change coils when needed.

Mouth to lung (MTL) tanks are designed to mimic the tight draw of a cigarette. They usually use higher resistance coils, smaller airflow, and lower wattage. Sub ohm tanks use coils under 1.0 ohm, larger airflow, and higher wattage to produce bigger clouds and a more open inhale. MTL tanks are usually better for nicotine salts and higher strength freebase. Sub ohm tanks suit high VG liquids and lower nicotine strengths.

Most modern tanks use a standard 510 connection, which is also used by most mods and many pod mods with adapters. As long as your device has a 510 connector and enough wattage to support the coil you plan to use, the tank should fit and function. Always check the device’s wattage range and compare it with the coil’s recommended wattage before pairing them.

For MTL tanks, thinner liquids such as 50VG/50PG and many nic salts work best because they wick easily at lower wattages. For sub ohm tanks, thicker high VG freebase e-liquids perform better, giving more vapor and smoother draws at higher power. If a tank is advertised as compatible with both MTL and restricted lung coils, you can usually run a wider variety of juices as long as you match the coil to the liquid type.

Coil life depends on the liquid, wattage, and usage, but many people get anywhere from a few days to a couple of weeks from a single coil. Signs it is time to replace include:

• Burnt or harsh taste
• Significantly muted flavor
• Very dark e-liquid in the tank after only a short time

Sweet and dessert style juices usually shorten coil life compared to lighter fruit or tobacco flavors.

Common causes include:

• Overfilling or liquid getting into the central airflow chimney
• Loose coil installation or worn out O-rings
• Very thin liquid in a tank with wide airflow
• Taking very soft draws at high power, which can flood the coil

Checking coil placement, not overfilling, and using the right VG/PG blend for the tank style can often fix minor leaking or gurgling.

Most modern tanks fill from the top by sliding or unscrewing the top cap. Fill slowly into the side fill port, not down the center chimney, and leave a small air gap at the top to avoid pressure issues. For maintenance:

• Rinse the tank with warm water when changing flavors
• Let it dry fully before reassembling
• Prime new coils with a few drops of e-liquid and let them sit in the filled tank for several minutes before first use

These habits help prevent dry hits and extend coil life.

Yes, but they are best used in MTL tanks or tanks that can run at lower wattage with higher resistance coils. Using high strength nic salts in a sub ohm tank at high power is usually too intense. If you want to use salts, choose a tank and coil combination that is specifically rated for mouth to lung or lower wattage use and adjust your nic strength to something comfortable.
