Vaporesso Gen S Vape Kit

TL;DR: The Vaporesso Gen S Vape Kit is a 220W dual-battery box mod with the NRG-S mini tank, GT mesh coils and Vaporesso's AXON chip. It suits cloud chasers and sub-ohm vapers who want serious power for under £20. Not ideal for beginners who want a small, simple pod kit. Note: it takes two 18650 batteries, sold separately.

Key Facts

• The Vaporesso Gen S fires from 5W to 220W using the AXON chipset.
• The Vaporesso Gen S runs on two 18650 batteries, which are not included in the box.
• The kit includes the NRG-S mini tank (2ml UK TPD) with GT4 and GT mesh coils.
• The Gen S supports coils from 0.03 to 5.0 ohm.
• Modes include Pulse Mode, Power Eco, Smart TC and DIY Mode.
• The Vaporesso Gen S costs £19.99 at Vape Online Store as of July 2026.

The Vaporesso Gen S Vape Kit is the answer to a simple question: how much power can you get for £20? A box mod is a larger vape with removable batteries and full wattage control, and the Gen S pushes that to 220W while staying light in the hand thanks to its rubberised coating. If you searched "what is Gen S", this is it: Vaporesso's high-power Gen mod paired with the NRG-S tank instead of the standard GT tank kit.

Key Specs Customers Check

• Batteries: dual 18650, sold separately. The mod does not ship with cells; grab two high-amp 18650s at checkout.
• Output: 5 to 220W. Huge headroom; most vapers run the included coils at 45 to 60W.
• Chip: Vaporesso AXON. Fast firing with Pulse Mode, which re-fires every 0.02 seconds for a consistent hit.
• Tank: NRG-S mini, 2ml (UK TPD). Slide top fill and adjustable bottom airflow.
• Coils: GT4 mesh and GT mesh included. The GT4 runs 30 to 70W and is best at 45 to 60W.
• Resistance range: 0.03 to 5.0 ohm. Takes the full GT coil family.
• Modes: Pulse, Power Eco, Smart TC, DIY. Eco mode stretches battery life when cells run low.
• Charging: micro-USB, 2.5A. An external battery charger is faster and kinder to the cells.

Pick Your Inhale: DTL power, MTL possible

DTL (direct-to-lung) is a fully open lung inhale for maximum vapour, and it is what the Gen S is built for. MTL (mouth-to-lung) is a tight, cigarette-like draw. The coil decides which you get:

• GT4 mesh (included): DTL at 30 to 70W. Big vapour with strong flavour; the everyday coil.
• GT mesh (included): DTL at similar wattage. A slightly different flavour profile; try both and keep your favourite.
• Higher-ohm GT coils (sold separately): a more restricted draw with the airflow closed down, though a dedicated MTL kit does this better.

Coils and E-Liquid Pairing

Sub-ohm coils need thick juice. Use a 70VG shortfill; VG (vegetable glycerine) is the thicker part of e-liquid that makes vapour, and thin liquid floods low-resistance coils. Pick from the 100ml shortfill e-liquids range at 3 to 6mg freebase nicotine. At 220W-class power, high nicotine strengths become harsh, so heavy smokers moving from cigarettes should start at 6mg and adjust. When your included coils wear out, the Vaporesso GT coils range covers GT2, GT4, GT6 and GT8 options from £5.99 a pack.

Batteries, Coil Life and Running Cost

Two good 18650 cells give a full day of vaping at 50 to 60W, and the Eco mode adds more when they run low. Remember the cells are not included: add a pair of Molicel P26A 18650 batteries at £5.49 each so the kit works out of the box. A GT coil lasts one to two weeks, and at roughly £2 to £3.30 per coil plus e-liquid, expect £5 to £8 a week in running costs, far below any disposable habit.

Compatibility and Refills

The NRG-S mini takes the standard Vaporesso GT coil range, the same coils used by the NRG and NRG SE tanks. It does not take GTX or GTi coils; those belong to Vaporesso's newer pod and iTank platforms, so check the packet says GT. The tank base is a standard 510 fitting, meaning the mod also accepts most other sub-ohm tanks up to 25.5mm wide.

Best Colours

The Gen S comes in a wide range of two-tone finishes. Plain Black is the most popular and the most discreet choice for anyone who wants the mod to disappear into a bag or jacket. Black Blue and Black Purple suit vapers who want some colour without going loud, while Black Green and the brighter finishes stand out and tend to appeal to vapers who like their hardware to look distinctive on the desk or at a meet-up.

How to Set Up the Vaporesso Gen S

1. Insert two 18650 batteries, matching the polarity markings inside the door.
2. Screw the NRG-S tank onto the 510 plate and check the preinstalled coil is snug.
3. Slide the top cap open and fill with 70VG e-liquid.
4. Wait 10 minutes so the coil primes, meaning the cotton soaks fully before the first fire.
5. Press the fire button five times to switch on, set 45W, and work up until the flavour peaks.

How to Make It Last Longer

• Buy cells as a matched pair and always charge and use them together.
• Check battery wraps monthly. A torn wrap on an 18650 must be re-wrapped or replaced before use.
• Never fire a dry tank. Refill before the liquid drops below the coil ports.
• Stay inside the coil's wattage band. Pushing the GT4 past 70W burns it early.
• Use Eco mode when battery is low instead of pushing full power.
• Clean the tank threads weekly so airflow and contacts stay crisp.

Vaporesso Gen S Price Comparison

The Gen S launched at around £45 to £50, and as of July 2026 many UK retailers no longer stock it at all. Vape Online Store lists it at £19.99, which buys a 220W kit for the price most stores charge for a basic pod device. Within the range, the newer Vaporesso Gen 200 kit adds the award-winning iTank and USB-C for £32.99, but if outright value is the goal, the Gen S is the cheapest dual-battery mod in the store.

Vaporesso Gen S FAQs

What is the Vaporesso Gen S?

It is Vaporesso's 220W dual-battery box mod sold with the NRG-S mini tank and GT mesh coils. The S refers to this NRG-S tank pairing rather than a different mod.

Does the Gen S come with batteries?

No. It needs two high-amp 18650 batteries, sold separately. Add a pair to your order or the kit will not fire.

Which coils fit the Vaporesso Gen S?

The full Vaporesso GT range, including GT2, GT4, GT6 and GT8. GTX and GTi coils do not fit; they belong to different Vaporesso tanks.

Gen S or Gen 200: which should I buy?

The Gen 200 is newer, charges by USB-C and uses the iTank with GTi coils. The Gen S offers more raw power for less money. Pick the Gen S for value, the Gen 200 for the newer tank.

What e-liquid should I use?

A 70VG shortfill at 3 to 6mg. Thin 50/50 liquids and nic salts are made for low-power pod kits and will flood a sub-ohm tank.

How long do the GT coils last?

One to two weeks for most vapers. A burnt or muted taste means it is time to swap the coil.

Why is my NRG-S tank leaking?

Reviewers on the E-Cigarette Forum and Vaping Underground rate the NRG-S as reliable, so leaks usually mean a worn O-ring, an unseated coil or thin e-liquid. Refit the coil, use the spare O-rings in the box and stick to 70VG juice.
