Geekvape Obelisk C Vape Tank

A sub-ohm DTL tank built for cloud chasers who still want proper flavour. The Geekvape Obelisk C runs Geekvape S Series mesh coils, comes with a tri-slotted adjustable bottom airflow ring, and fills through a threaded top-fill system that keeps refills quick and mess-free.

2ml TPD-compliant capacity, stainless steel build, 510 threaded, and finished with an 810 wide bore drip tip for those deep, open-lung pulls. Push-to-fit coil installation means no threading and no fuss. Four colours in the store picker. Over 18s only. Browse more DTL Tanks at Pirate Vapes.

Why vapers choose the Obelisk C:

• Tri-slotted bottom airflow gives a genuinely adjustable draw instead of the single fixed setting most budget sub-ohm tanks offer

• S Series mesh coils ramp up fast and hold their flavour longer than standard wire builds, according to Geekvape's coil testing

• Push-to-fit coil swaps take seconds. No threading, no guessing whether it is seated properly

• 810 wide bore drip tip suits big, open-lung DTL pulls and pairs well with high-VG liquid

• Stainless steel construction shrugs off the odd knock that would crack a cheaper plastic tank

Geekvape Obelisk C Vape Tank Features

The Airflow Ring Actually Does Something

Most sub-ohm tanks in this price bracket ship with a basic slotted ring that barely changes the draw. The Obelisk C's tri-slotted AFC is genuinely adjustable, wide open for maximum cloud and a looser lung hit, or dialled back for a warmer, more restricted pull. Worth experimenting with both coils to find your sweet spot.

Two Coils, Two Very Different Vapes

The tank ships with both a 0.25ohm dual mesh coil rated at 45-55W and a 0.15ohm single mesh coil rated at 80-90W. The dual coil gives a balanced, everyday DTL vape with strong flavour and manageable vapour. The single mesh pushes into proper cloud territory. Start on the dual coil if you are new to sub-ohm tanks, then try the single mesh once you know your mod can handle it.

Push-to-Fit, Not Screw-In

Coil swaps take one motion: pull the old coil out, press the new one in until it seats. Push-to-fit designs like this reduce the risk of cross-threading a coil, which is a genuinely common way coils get damaged before they even reach the cotton. Fair enough, it also just saves time.

Top Fill With Dual Ports

Threaded top-fill with two fill ports means less chance of e-liquid pooling in the wrong place while refilling. Twist the cap, fill, twist it closed. The seal underneath the cap is designed to be leak-resistant even when the tank is on its side in a bag.

Built From Steel, Not Plastic

Stainless steel construction across the main body. Sub-ohm tanks take more knocks than most, especially if you are swapping coils regularly or carrying the tank loose in a pocket. Steel handles that better than the resin bodies used on cheaper alternatives. Pair it with a Box Mod that can comfortably run down to 0.15ohm if you want to use the single mesh coil.

How to Set Up the Geekvape Obelisk C Vape Tank

Five steps. A couple of minutes if the coil is not already fitted.

1. Unscrew the top cap by turning it anticlockwise to expose the fill ports.

2. Press the S Series coil into the base until it seats firmly. No threading required.

3. Prime the coil with four to five drops of e-liquid directly into the coil's exposed mesh ports.

4. Fill through the top ports, keeping liquid clear of the central airflow tube, then screw the cap shut.

5. Leave the tank to stand for eight minutes before your first draw. Mesh coils need the extra time to fully saturate, and rushing this step on a sub-ohm coil burns the wick almost instantly.

Once primed, start at the lower end of the coil's wattage range and work upward until the flavour and vapour balance suits you.

What's in the Geekvape Obelisk C Vape Tank Box

• One Obelisk C tank, 

• one pre-installed 0.25ohm dual mesh coil,

• and the user manual. 

No e-liquid, no mod, no battery included.

Built for Sub-Ohm Mods, Not MTL Devices

The Obelisk C's 510 threading fits any standard 510 mod or box mod capable of running down to 0.15ohm. It is designed specifically for sub-ohm, direct-to-lung vaping with High-VG E-Liquid at 60% VG or above. This is not a tank for MTL Pod Kits or low-wattage pen devices; the airflow and coil resistance are built for cloud production, not a tight cigarette-style draw.

What it does not fit: any device that cannot output at least 45W, and any MTL pod system regardless of thread type. Check your mod's wattage ceiling before ordering replacement Geekvape Coils.

About Geekvape

Geekvape built its name on rugged, performance-focused hardware, and the Obelisk line sits firmly in that tradition. The Obelisk C itself is a revision of an earlier Geekvape sub-ohm tank, rebuilt around the newer S Series mesh coil platform for faster ramp-up and longer-lasting flavour.

Geekvape's core strength has always been coil engineering, and the dual and single mesh options on the Obelisk C reflect that: two genuinely different vaping experiences from the same tank body, rather than one coil dressed up as two.

Stock Up and Save

Mesh coils on a sub-ohm tank do not last as long as MTL coils, especially on the 0.15ohm single mesh at higher wattage. Grabbing a spare pack of S Series coils alongside the tank means you are not caught short mid-week. Pick up a bottle of high VG e-liquid at the same time, and you have everything sorted in one order.

Every order from Pirate Vapes ships same day before 4 pm in padded packaging. TPD compliant stock, age-verified checkout, over-18s only. Free Pirate Post on orders over £25.

Conclusion

The Obelisk C is a genuinely adjustable sub-ohm tank at a fair price point, with two coil options that cover both balanced flavour-chasing and serious cloud production. It has tri-slotted airflow, push-to-fit coils, and a stainless steel build that holds up to daily use.

If you want a DTL tank that does not force you into a single vaping style, this is worth a look. Browse the full range of Vape Tanks and vape accessories, or head back to Pirate Vapes for more from the Geekvape Range.

FAQs

What coils fit the Obelisk C?

Geekvape's S Series mesh coils, either the 0.25ohm dual mesh at 45-55W or the 0.15ohm single mesh at 80-90W. Both come included in the box.

Is this tank suitable for MTL vaping?

No. The Obelisk C is a sub-ohm DTL tank built for open-lung draws and high-VG liquid. For a tighter, cigarette-style draw, look at an MTL tank instead.

What e-liquid should I use?

High-VG e-liquid, ideally 60% VG or above. Sub-ohm mesh coils are not designed for 50/50 blends and will not wick properly with thinner liquid.

How often do the coils need replacing?

Roughly every one to two weeks with regular use, sooner on the 0.15ohm coil if you are running it near the top of its wattage range. Flavour dropping off is the usual sign it is time to swap.

Does the Obelisk C fit any mod?

Any mod with 510 threading that can output at least 45W, ideally with a range up to 90W to make use of both included coils.
