Geekvape Obelisk Tank 

A proper sub-ohm tank built for cloud production, not a halfway house between MTL and DTL. The Geekvape Obelisk holds 2ml of e-liquid within the UK's TPD limit and runs on Geekvape's Z Series mesh coils, with a 0.2ohm rated for 70-80W and a 0.4ohm rated for 50-60W both included in the box.

Stainless steel construction, a child-lock top-fill system, and a dual-slotted bottom airflow ring designed to feed those higher wattages without choking the draw. An 810 wide-bore drip tip comes fitted as standard. Stocked in six finishes at Pirate Vapes. Over 18s only, and this is strictly a device for mods built to fire sub-ohm coils.

Why vapers choose this:

• Genuine sub-ohm performance. The 0.2ohm coil at 70-80W produces serious cloud volume, not a watered-down version of it.

• Two coils in the box. You are not buying a spare before you have even opened the tank.

• Child-lock top fill. Refills stay contained, and the cap is not something a curious toddler can pop open by accident.

• 810 wide-bore drip tip. Fitted as standard rather than sold separately, which most sub-ohm tanks at this price do not bother with.

• Six colourways. More choice than most replacement tanks offer at this end of the market.

Geekvape Obelisk Tank Replacement Features

Z Series Mesh, Built for Watts

Geekvape's Z Series Coils use a KA1 mesh heating element designed to handle higher wattage without the flavour dropping off after a few tanks. The 0.2ohm variant is rated all the way up to 80W, which is a genuinely high ceiling for a tank this compact. Honestly, most sub-ohm tanks in this price bracket cannot claim the same.

Two Coils, One Clear Purpose

Both included coils, the 0.2ohm and the 0.4ohm, sit at the DTL end of the spectrum. Neither is built for a tight MTL draw. Fair enough if that catches out anyone expecting a hybrid tank: this is built purely for dense, warm clouds and flavour at volume.

Airflow That Actually Keeps Up

Higher wattage needs more air, and Geekvape's dual-slotted bottom airflow ring is sized for exactly that. Open it fully for the 0.2ohm coil's top end, or dial it back when running the cooler 0.4ohm setup.

A Fill System That Locks

The top-fill port uses a child-lock mechanism rather than a simple flip cap. Small extra step when refilling, but it means the tank is not something that opens with a light knock in a bag, and it keeps curious hands away from the liquid inside. Worth pairing with a proper high-VG shortfill.

Built Stainless, Not Fragile

Stainless steel housing around a Pyrex glass section means this tank shrugs off the odd knock that would crack a cheaper plastic tube. Not indestructible, but a genuine step up from entry-level sub-ohm tanks.

How to Set Up the Geekvape Obelisk Tank Replacement

A few extra steps compared with a basic tank, thanks to the child-lock fill system.

1. Unlock and remove the top cap by pressing down while twisting, then set it aside.

2. Choose your coil. Press-fit the 0.2ohm for maximum cloud, or the 0.4ohm for a slightly cooler, more controlled draw.

3. Prime the coil with three to four drops of e-liquid directly onto the mesh through the airflow slots before fitting it into the tank.

4. Fill through the top port to just below the max line, then lock the cap back into place.

5. Give it a full ten minutes before your first draw. Sub-ohm mesh at this wattage punishes an unsoaked coil badly.

6. Start low and build up. Begin around 50W on the 0.4ohm or 70W on the 0.2ohm, then adjust to taste.

What's in the Geekvape Obelisk Tank Replacement Box

One Obelisk tank body, a 0.2ohm Z Series coil pre-installed, a 0.4ohm Z Series coil as a spare, a coil removal tool, a spare parts pack, and a spare glass tube. No device and no e-liquid, so make sure your mod can handle sub-ohm firing before you order.

Built for Serious Sub-Ohm Mods

The Obelisk tank uses a standard 510 connection, so it physically fits the vast majority of box mods on the market. What matters more is whether your mod can actually fire down to 0.2ohm safely.

Check your device's minimum resistance rating before fitting the lower coil, since this is not a tank built for entry-level or MTL-focused devices. Browse DTL Tanks for other cloud-focused options if you are still shopping around, or Vape Mods if you need a device capable of running it properly.

About Geekvape

Geekvape built its reputation on rugged, high-output hardware, and the Obelisk sits alongside the brand's Zeus and Z lines as one of its dedicated sub-ohm tanks. The Z Series coil platform used here was developed specifically for higher-wattage cloud production, moving away from the lower-power coil designs Geekvape uses across its MTL-Focused Tanks. It is a straightforward proposition: fewer gimmicks, more focus on getting flavour and vapour right at volume.

Stock Up and Save

Running a 0.2ohm coil at 80W burns through a coil faster than a gentler MTL setup ever would, so keeping spares in stock matters more here than with most tanks. Pirate Vapes dispatches every order the same day before 4pm, with padded packaging that protects the glass in transit.

All stock is TPD compliant and age-verified at checkout, restricted to over 18s only throughout.

Conclusion

The Geekvape Obelisk Tank Replacement is built for one job: proper sub-ohm vaping without the compromises smaller hybrid tanks make. Two Z Series coils in the box, a genuinely wide wattage range, and a child-lock top-fill system that takes the fuss out of daily use.

Just make sure your mod is rated for it before you order the lower resistance. Check our Geekvape Coils range for spares once the included pair wear in, browse vape accessories for the rest of your setup, and pick one up at Pirate Vapes.

FAQs

Is this an MTL or DTL tank?

DTL only. Both included coils are sub-ohm and built for cloud and flavour at higher wattage, not a tight cigarette-style draw.

What is the actual UK capacity?

2ml, the TPD limit. Some international listings show up to 5.5ml, but UK stock is capped at 2ml.

Will my mod handle this tank?

It fits any 510 connection, but your mod needs to be rated to fire down to 0.2ohm safely. Check your device's minimum resistance before fitting the lower coil.

How long do the Z Series coils last?

Typically one to two weeks with regular use, shorter at the top of the wattage range and longer if you keep to the 0.4ohm coil.

Does it come with spare parts?

Yes. A spare glass tube, a small spare parts pack, and a coil tool are all included alongside the two coils.

Can I buy replacement coils separately?

Yes, Geekvape Z Series coils are sold separately once the included pair wear out.
