Innokin Endura T20-S Vape Tank

Innokin Endura T20-S Vape Tank

At 20.5mm across, this is one of the slimmer MTL tanks going, and that is the point. The Innokin Endura T20-S is a 2ml refillable mouth-to-lung tank running the Prism S coil system, with a top-fill cap, fixed dual airflow and a 510 Delrin drip tip.

It takes a 0.8ohm coil for a warmer draw and a 1.5ohm coil for a tighter, cigarette-style pull, so you tune the vape by the coil rather than fiddling with a ring. Built for ex-smokers and anyone after a simple, reliable MTL setup. A steady pick among MTL Vape Tanks at a price that does not sting.

Why vapers choose this:

• Two coils, two draws. The 1.5ohm at 13 to 14W gives a tight, discreet, cigarette-style hit that suits higher-strength nic salts, while the 0.8ohm at 16 to 18W runs warmer with a touch more vapour. You pick the feel by swapping the coil.

• No-spill coil swap. The Prism S system lets you change coils without draining the tank first, so there is no mess and no wasted juice.

• 20.5mm slim. Looks right on a pen battery or a compact mod, not oversized.

• Delrin drip tip stays cool on longer sessions, unlike bare metal tips.

• Cheap to run and cheap to buy, which is the whole reason the Endura line has stuck around.

Innokin Endura T20-S Features

Easy Prism S Coil System

This tank lives or dies on its coils, and the Prism S heads are the good part. Bottom vertical coil, organic cotton wicking, and an integrated 510 pin so installation is a straight push-fit. Flavour comes through clean on both resistances. Keep a spare pack of Replacement Vape Coils in the drawer, and you are never caught out by a burnt hit.

Fixed Airflow For MTL Vaping

Adjustable airflow rings sound good until they loosen, drift, or clog. This one is fixed, tuned by Innokin to the coils it runs. The 1.5ohm gives a proper tight MTL draw; the 0.8ohm opens it up a little. Honestly, for a set-and-forget MTL tank, fewer moving parts is the smarter design.

Simple Top-Fill Design

Unscrew the top cap, pour in your juice, screw it back. The tank stays on your mod the whole time, and there is no unscrewing the base or dealing with the coil to refill. Pair it with a 50/50 Vape Juice and topping up takes seconds.

Strong Stainless Steel And Pyrex Build

Stainless steel body, Pyrex glass, the sort of build the Endura name has traded on for years. It is not trying to be clever. It is trying to last, and that is what it does.

Seven Colours To Choose From

The hardware is the same across the range, but the finishes are not. From a plain stainless build to a rainbow anodised shell, there is a colour to sit against whatever mod you already own. Swap the Vape Drip Tips too if the standard Delrin tip is not your shape.

Innokin Endura T20-S Colours

Seven finishes in the store picker, all on the same slim stainless body. Darker shades hide marks; the brighter and anodised options stand out more. Pick whichever suits your setup.

How to Set Up the Innokin Endura T20-S

Quick job, a couple of minutes plus the soak.

1. Unscrew the base and push the old coil out if you are fitting a fresh one.

2. Line the new Prism S coil up and push it firmly into the base until it seats, then reattach.

3. Drip three or four drops of e-liquid straight onto the exposed cotton so it is not going in dry.

4. Screw the top cap open, fill with 50/50 or high-PG liquid, and close it up.

5. Let it sit for a full five minutes, then take two or three pulls without firing to draw liquid through the wick.

6. Start at the low end of the coil's range and build up until the draw feels right.

What's in the Innokin Endura T20-S Box

The tank ships with a Prism S coil fitted and a spare drip tip, ready to run once you add juice and a battery. It does not include any e-liquid, and it does not include a mod, so you will need a 510 device to fire it.

Coil count in the box varies by supplier, so it is worth adding a five-pack of Prism S coils to your order. A spare Replacement Tank Glass is cheap insurance against a cracked window down the line.

Fits Most 510 Mods and Pen Batteries

The Endura T20-S uses a standard 510 connection, so it drops onto essentially any regulated mod or pen battery that can reach the coil's low wattage range. Being an MTL tank, it is happiest on simple Vape Mods and tube batteries rather than high-power devices, and the team at Pirate Vapes can help if you are unsure yours suits it.

The Prism S coils are shared with the EZ.WATT kit and the Endura Apex pod, but note they will not fit the older T20 tank. Run it on a device that pushes 13 to 18W, and it performs.

About Innokin

The Endura line is where a lot of UK vapers started, and it built its name on affordable, low-power MTL kit that just works. The T20-S carries the Prism S coil platform, Innokin's flavour-focused MTL system with the no-spill coil swap, and pairs it with the simple stainless build the Endura range is known for.

It is deliberately basic hardware aimed at reliability over gimmicks, which is why the Innokin Range stays a go-to for ex-smokers and MTL vapers who value consistency.

Stock Up and Save

At this price, the Endura T20-S is one of the easiest tanks to recommend to anyone after a fuss-free MTL setup, and the coils cost little to keep topped up. Pirate Vapes ships every order with Free Pirate Post on baskets over £40, packed with care so nothing rattles loose.

All hardware is sold to over-18s only through age-verified checkout, and every tank is TPD compliant at the 2ml UK capacity.

Conclusion

The Innokin Endura T20-S is a slim, honest, low-cost MTL tank that does exactly what an ex-smoker needs and no more. Two coil resistances cover a tight or slightly warmer draw, the top-fill is painless, and the Prism S coils are cheap and easy to swap.

Pair it with a battery from our MTL Kits or a spare part from the Vape Accessories shelf, all from Pirate Vapes.

FAQs

What coils does the T20-S take?

Innokin Prism S coils, in 0.8ohm (16 to 18W) and 1.5ohm (13 to 14W). A 0.9ohm mesh version exists in the range too. They push straight in, no threading.

Is the T20-S tank MTL or DTL?

Mouth-to-lung. The 1.5ohm gives a tight cigarette-style draw; the 0.8ohm runs a little warmer with slightly more vapour, but it is still an MTL tank.

How much does the T20-S tank hold?

2ml, in line with UK rules. Refill through the top cap without taking it off the mod.

What e-liquid suits the T20-S?

50/50 or high-PG. Nic salts at higher strengths pair well with the 1.5ohm for a strong throat hit.

Will the T20-S coils fit my old T20?

No. Prism S coils are for the T20-S, EZ.WATT and Endura Apex. They do not fit the original T20 tank.

Does the T20-S airflow adjust?

No, it is fixed dual airflow. You change the draw by switching between the 0.8ohm and 1.5ohm coils instead.
