Innokin Endura T20-S Vape Kit
The best starter kit is usually the one with the fewest decisions to make. The Innokin Endura T20-S has one button, one fixed power setting, and a tank that fills from the top in seconds, which means the only real choice left is which e-liquid to put in it. That's where we come in, and it's exactly why we've paired this kit with a free bottle of e-liquid built to suit it.
The Innokin Endura T20-S Vape Kit is £19.99 (inc. VAT), and that price already includes a 10ml bottle of Platinum e-liquid. Available in four colours.
Matched from the start, not an afterthought
A lot of starter kits get bundled with whatever e-liquid happens to be spare, rather than what actually suits the device. The T20-S runs its coils at a fixed 18W and is built for a mouth-to-lung draw, which is exactly the profile our Platinum e-liquid range is formulated for, a 50/50 PG/VG blend that wicks cleanly through low-wattage coils without the dry hits thicker juice can cause.
Key Features
1500mAh built-in battery. Comfortably covers a full day of normal use for most vapers, with a simple 3-level LED (green, yellow, red) as the only indicator you need.
18W fixed output. No wattage dial or menu to navigate, the T20-S is tuned to the right power for its coils from the moment you take it out of the box.
2ml top-fill tank, UK TPD-compliant. Unscrew the cap, fill, replace it, no bottom-fill valve to align.
0.8Ω and 1.5Ω Prism-S coils. The 0.8Ω comes pre-installed for a slightly fuller flavour and vapour, the 1.5Ω option (also compatible) tightens the draw further for an even more cigarette-like pull.
Single-button design with lock. Five clicks locks the fire button, useful for travelling or dropping it in a bag.
Vape-while-charging. Keep using it while it's plugged in, no need to wait out a full charge if you're running low.
Stainless steel construction. A slim pen shape that holds up to daily use without adding bulk.

It's a slim cylindrical pen rather than a boxy mod, so one diameter figure covers both width and depth, about the footprint of a slim highlighter pen.

Compatibility Guide
The T20-S uses Innokin's Prism-S coil family, shared with the Prism T20S tank and several other Innokin devices, so replacements are widely available as this range grows.
Compatible coils: 0.8Ω and 1.5Ω Prism-S coils.
Compatible e-liquids: Best matched to 50/50 PG/VG e-liquid, like the included Platinum range, nic salts also perform well, particularly on the 1.5Ω coil. High-VG shortfills aren't a good fit, the low wattage and restricted airflow aren't designed for thick juice.
Charging cable: Standard Micro-USB, not USB-C, worth checking you've got a compatible cable or plug to hand.
Recommended E-Liquids
Every T20-S kit comes with a free 10ml Platinum e-liquid, our house 50/50 blend built around exactly this style of low-wattage MTL device. Beyond the one included, our full Platinum range covers:
- Platinum E-Liquid 10ml
- Red Tobacco Platinum E-Liquid
- Sahara Tobacco Platinum E-Liquid
- Grape Platinum E-Liquid
- Peppermint Platinum E-Liquid
- Full range: Platinum E-Liquid at Pure E-Liquids
Prefer a stronger throat hit? Our Nic Salts range pairs particularly well with the 1.5Ω coil.
Coil and Usage Guide
0.8Ω Prism-S (pre-installed). A slightly more open draw, with a touch more flavour and vapour than the 1.5Ω option, a solid all-rounder.
1.5Ω Prism-S. Tighter and closer to a cigarette's draw, best paired with higher-strength e-liquid for vapers who want maximum throat hit without much vapour.
Coil lifespan. Expect one to two weeks of regular use per coil, a burnt or flat taste, or a gurgling sound on the draw, means it's time to swap. Prime a new coil by letting it sit filled for a few minutes first.
Filling the tank. Unscrew the top cap and fill down the side of the chimney, avoiding the centre tube, leave a small air gap rather than filling right to the top.
Usage Advice
Give the T20-S a full charge before first use, around 60 to 90 minutes from empty on a standard Micro-USB charger.
Always prime a new coil, five minutes filled and resting before your first draw prevents a burnt, dry hit.
Stick to 50/50 e-liquid or nic salts, not thick shortfills, the wattage and airflow here aren't built for high-VG juice.
Use the five-click button lock when it's in a bag or pocket, so it doesn't fire by accident.
Frequently Asked Questions
Is the Innokin Endura T20-S suitable for someone switching from smoking?
Yes, that's exactly what it's designed for. The tight, restricted draw feels close to a cigarette, and there's nothing to set up, just fill, charge and go.
How long does the battery last?
The 1500mAh battery typically lasts a full day of normal use for most vapers, depending on how often you're puffing.
How long does it take to charge?
Around 60 to 90 minutes from empty on a standard Micro-USB charger.
Is the wattage adjustable?
No, it's fixed at 18W, there's no dial or menu, the kit is built to work correctly straight out of the box.
What's the difference between the two coils?
The 0.8Ω (pre-installed) gives a slightly more open draw with more flavour and vapour, the 1.5Ω gives a tighter, more cigarette-like pull with less vapour.
Which e-liquid should I use?
50/50 e-liquid like the included Platinum range, or nic salts for a stronger throat hit. Avoid thick, high-VG shortfills, which aren't suited to this kit's low wattage.
Does the kit come with e-liquid?
Yes, every kit includes a free 10ml bottle of Platinum e-liquid at no extra cost.
How often should I change the coil?
Roughly every one to two weeks with regular use, a burnt taste or gurgling sound are the usual signs it needs replacing.
Can I use it while it's charging?
Yes, the T20-S supports vape-while-charging.
What's the maximum nicotine strength I can use?
20mg (2%) is the UK legal maximum, and a sensible strength for most smokers switching over.
Does it leak?
It's a standard top-fill tank, keeping it upright and not overfilling helps prevent leaking, as with any refillable tank.
What colours does it come in?
Four colours: Black, Blue, Grey and Red.
Is this a good first kit for a complete beginner?
Yes, it's built specifically for that, one button, no settings, and a familiar cigarette-like draw.
Can I buy replacement coils on their own?
Yes, The Innokin Prism S range of coils are the replacement coils for use with the Innokin Endura T20-S.
