Obelisk Tank by Geekvape

£12.49 Was £17.99

Select one of the following

The Geekvape Obelisk tank is a 2ml, sub-ohm tank designed for use with the Zeus coil range.

  • 2ml tank for the Geekvape Obelisk
  • 510 Connection
  • Works with Geekvape Zeus coil range (not included)
  • Push-fit coil design
  • Leakproof, childproof design
  • Sliding, top-fill
  • Wide bore drip tip
  • Slotted bottom airflow control

The Geekvape Obelisk tank's 510 connection means it can be paired with most vape mods for sub-ohm, Direct-Lung vaping. (See more in the FAQs below).

The tank's convenient push-fit design makes switching coils super simple and eliminates the need for fiddly, time-consuming coil changes.

More versatility is offered by the tank's bottom slotted airflow control. Simply adjust the airflow to get an airier or more restricted vape depending on which you prefer.

The transparent design of the tank means you can easily keep track of your e-liquid levels to prevent you from running out and burning the coil. When it is time to refill, the sliding top filling design makes it simple and prevents any pesky mess or wastage.


The Geekvape Obelisk tank works with the Geekvape Zeus coil range (not included) and is recommended for use with high VG e-liquids (VG:PG 70:30 and above).


What e-liquid can you use in the Geekvape Obelisk tank?

When used with Geekvape 0.4ohm Z1 and 0.2ohm Z2 coils, the Obelisk tank is best used with high VG e-liquids with a VG:PG ratio of around 70:30 or 80:20.

What is sub-ohm vaping?

Sub-ohm vaping refers to vaping with a coil with an ohm (ohm) rating below 1.0. When pairing low resistance coils with high powered devices and high VG e-liquids, this method of vaping will produce thicker, denser vapour clouds, more intense flavour and stronger nicotine hit.

Do note that while sub-ohm originally referred to vaping with any coil less than 1ohm, vape technology has advanced and some modern MTL coils often have a resistance of less than 1ohm.

See The Beginners Guide to Sub-Ohm Vaping for more information.

What is the difference between Mouth-to-Lung (MTL) and Direct-Lung (DL) vaping?

In Mouth-to-Lung vaping you inhale vapour and hold it in your mouth for a moment before inhaling again for the vapour to reach your lungs. In Direct-Lung vaping you inhale in one continuous breath into your lungs. See MTL v DL for more information.

Product Care

All tanks & pods

  • Use the correct e-liquid for the coil/pod you are using - see recommended e-liquids on the product description page on E-Cigarette Direct.
  • Avoid filling the tank or pod above the fill line or to the very top.

Tanks & pods: Replaceable coil

  • When adding a new coil, ‘prime’ it first by allowing e-liquid to soak in for at least five minutes before use.
  • When device is switched on, only press fire button when inhaling. This prevents condensation build up in the pod or tank.
  • Push/screw coils in firmly but don’t over-tighten.
  • Use the correct power settings for the coil you are using. You will usually find this on your manual or on the coil itself.
  • Always keep some e-liquid in the pod or tank. The key here is to ensure the coil is saturated with e-liquid so it does not dry out. 
    When travelling on 

Tanks & pods: Fixed coil.

  • When using a new pod for the first time, allow e-liquid to soak in for five minutes before using. 
  • When device is switched on, only press fire button when inhaling. This avoids condensation in the pod or tank.
  • Keep some e-liquid in the pod at all times. The key here is to ensure the coil is covered with e-liquid so it does not dry out. 
  • When travelling on a plane, empty pods before use, as changes in air pressure can cause leakage. 

Keeping a tank or pod clean

Keep the mouthpiece clear, especially if you spend a lot of time doing outdoor activities such as gardening or if you find the airflow is affected. If you have a removable mouthpiece, remove and blow through it to clear it. You can further clean the mouthpiece by pushing some kitchen towel or a cotton bud through it.

Occasionally cleaning your tank can improve performance. To clean, first, remove all e-liquid from the tank. If you have a replaceable coil, remove it. Wash the tank using warm but not boiling water. Allow the tank to dry completely before using it again, as water can affect the quality of your vape.
