Vaporesso Gen S Vape Kit

Vaporesso Gen S Vape Kit

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.

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 5.0Ω.
• 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.

Vaporesso Gen S Specifications

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:

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 26mm wide without overhang.

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 the batteries: Match the polarity markings inside the door. A ribbon is fitted to help with removal. The magnets are strong and the door sits with zero rattle.
2. Screw on the tank: Attach the NRG-S to the 510 plate and check the preinstalled coil is snug. The plate is slightly raised to prevent scratches.
3. Fill the tank: Slide the top cap open and fill with 70VG e-liquid. Leave a small air gap. If you're using a large bottle, remove the drip tip first for easier filling.
4. Prime the coil: Wait 10 minutes so the cotton soaks fully. Skipping this is the #1 cause of a burnt first puff.
5. Turn on and set wattage: Press the fire button five times to switch on. Set 45W and work up until the flavour peaks — around 60–65W on the included coils.
6. Adjust airflow: The airflow ring is smooth, easy to adjust and has a stopper. Open it fully for DTL, close it down for a more restricted draw.

How to Make It Last Longer

• Buy cells as a matched pair and always charge and use them together. Mixing old and new cells is unsafe in a dual-battery mod.
• 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 75W 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.
• Watch the O-rings. The kit includes four spare O-rings. A worn O-ring is the usual cause of a leak — swap it before assuming the tank is faulty.

What UK Vapers Say

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.

Conclusion

The Vaporesso Gen S Vape Kit is the cheapest way to get a genuine 220W dual-battery box mod in the UK right now. At £19.99, you're paying pod-kit money for a mod that launched at £45–£50 and is now discontinued at most major retailers. The AXON chip, Pulse Mode and rubberised build are proven, and the NRG-S tank delivers proper sub-ohm flavour despite the noisy airflow and average coil life.

It's not for everyone. You need to buy two 18650 batteries separately, the tank is 2ml (not the 8ml US version), and the coils last 50–60ml rather than weeks. But if you want DTL power on a budget and don't mind a bit of coil-swapping, nothing else at this price comes close.

Grab a pair of Molicel P26As, a 70VG shortfill and a spare pack of GT coils when you order. That's a complete setup for under £40 that will outlast a drawer full of disposables.
