Flavour is spot on
Not too strong, not too mild — just right. Good for all day use without being overpowering.
GeekvapeThe GeekVape Obelisk 200W Dual Battery Sub-Ohm Vape Kit by Geekvape across 4 flavours at 0mg. Free UK delivery over £20, same-day dispatch on weekday orders before 4pm.
The Geekvape Obelisk 200W Dual Battery Sub-Ohm Vape Kit is a reusable box-mod system built around two removable 18650 cells and a sub-ohm tank. It sits at the high-power end of the Geekvape range, in the same general territory as the Aegis kits, and it is aimed at vapers who want large vapour production, strong flavour and control over wattage rather than a slim pod device that fits in a jeans pocket. The name tells you most of what matters: Obelisk is the design family, 200W is the ceiling of the power output, and dual battery means the mod runs on two cells, which is how a mod reaches that wattage with comfortable headroom instead of pushing a single cell to its limit.
This is a reusable system, not a disposable. You fill a tank with e-liquid, fit a replaceable coil, drop two 18650 batteries into the mod and adjust the output to suit the coil and the liquid you are using. Single-use vapes have been banned from sale across Great Britain since June 2025, and a refillable kit like this one is the sensible long-term replacement if you used to rely on large-puff-count disposables and want a lower running cost and less waste.
What the kit gives you in practice:
Because specifications can differ slightly between production batches, always check the product page and the packaging for the exact tank model, the coil resistance supplied in the box and whether the 18650 cells are included. In most UK listings for kits of this type the batteries are sold separately, so assume you will need to buy two matched high-drain cells and a charger unless the listing says otherwise.
This guide walks through how the kit performs, how to set it up, which e-liquids and nicotine strengths make sense, what to do when something goes wrong, and how it stacks up against other kits you might be considering at a similar price.
A 200W ceiling does not mean you vape at 200W. That number is the top of the range, and for most people it is never touched. The practical value of a high-output mod is that it can drive low-resistance mesh coils comfortably across their recommended range without the mod sitting at its limit all the time. A coil rated for 50W to 80W, which is a very common range for sub-ohm mesh, runs easily on a mod like this, and you can step up or down a few watts at a time until the vape feels right.
Here is how the output typically translates into the experience:
Vapour production on a sub-ohm setup is noticeably larger than on any pod kit. That is a feature if you like big clouds and a warm inhale, and a drawback if you want something discreet for use in a shared flat or on a train. The vapour is thick and lingers, so it is considered good etiquette to vape outdoors or in designated areas, and many workplaces, public transport and venues restrict it entirely.
Ramp-up, the delay between pressing the fire button and the coil reaching working temperature, is short on a mesh coil at sensible wattage. Running a coil at the very bottom of its range makes it feel sluggish, and running it above the top of its range can cause dry hits. If you are unsure, start in the middle of the rating printed on the coil, take a few puffs and adjust up or down from there.
Draw style matters too. Sub-ohm tanks are designed for a direct-lung inhale, meaning you breathe the vapour straight into your lungs rather than holding it in your mouth first. If you are used to a mouth-to-lung disposable or pod, the first few draws can feel large and airy. You can close the airflow ring partly to tighten the draw, and dropping the wattage a little will make the transition much smoother.
Flavour on a kit like this depends on three things: the coil, the wattage and the e-liquid. The Obelisk 200W is a flavour-capable platform because mesh coils have a large heating surface area, which warms the liquid evenly and produces cleaner, fuller taste than the older round-wire sub-ohm coils did. You tend to get more of the top notes and the sweetness of the liquid, and the lower notes in a fruit or dessert flavour come through with more body.
What works well in a high-power sub-ohm tank:
As a general rule, a higher PG ratio (for example 50VG/50PG) carries flavour more sharply and gives a stronger throat hit, while a higher VG ratio (70VG/30PG or more) produces thicker vapour and a smoother inhale. Most shortfills sold in the UK are 70VG/30PG or 80VG/20PG, which suit sub-ohm tanks and mesh coils well. A 50/50 liquid suits lower wattage use and keeps the coil wicking comfortably, but it can leak more readily in a tank with generous airflow.
Fresh coils always taste a little off. Prime the cotton thoroughly, wait several minutes after the first fill, and start at the low end of the coil range for your first few draws. After that the flavour settles into its proper character. Coils generally taste their best in the first week of normal use and then gradually dull as residue builds up, especially with sweeter liquids. If a particular liquid begins to taste muddy, a fresh coil often fixes it faster than any change in wattage.
The kit itself has no flavour. It is a delivery system, and the character of your vape comes from the liquid and the coil, which is why it is worth keeping a couple of different liquids to hand when you first set the kit up so you can find the wattage and flavour pairing you prefer.
The Obelisk 200W follows the broad Geekvape formula for a dual-battery mod: a rectangular body with rounded edges, a fire button on the front and a battery door that gives access to both cells. The housing is a metal alloy shell, which gives it a solid hand feel and the ability to take a bump or a drop from pocket height without cosmetic damage in normal use. Geekvape has built its brand on durability, and the Aegis range in particular is known for rugged construction, so it is reasonable to expect similar attention to the housing here, although you should still treat it as a piece of electronics rather than a tool.
Some practical points on the build:
The range is offered in several colourways. On this site the variants include black, blue, gunmetal and silver among others, and stock moves around so availability changes. The colour makes no difference to performance, so choose on looks. Darker finishes hide fingerprints better; lighter finishes show scratches less obviously. If you like to carry the device loose in a bag, the darker colours tend to look fresher for longer.
Build quality is also about what happens over time. Keep the 510 connector and the battery contacts clean, wipe the housing with a slightly damp cloth, avoid leaving the device on a hot car dashboard, and do not rinse the mod under a tap. Only the tank gets rinsed. A mod that is kept dry and clean will outlive several tanks and many hundreds of coils.
Battery handling is the part of a dual-18650 kit where it pays to be careful. The Obelisk 200W runs on two removable 18650 lithium-ion cells, which are a standardised cylindrical format around 18mm wide and 65mm long. A 200W maximum output is only achievable if the cells can deliver the current, so the cells you buy matter as much as the mod does.
Whether the cells are included depends on the listing. In most UK kits of this type they are sold separately, partly because shipping lithium cells is regulated and partly because many vapers already own a set. If they are not included, buy two matched, genuine, high-drain 18650 cells from a reputable UK supplier. Look for a continuous discharge rating of at least 20A. Popular choices include the Samsung 25R, LG HG2 and Molicel P26A. Avoid unbranded cells and any listing that claims an unrealistic capacity, since a cell with an inflated mAh figure is usually a re-wrapped or fake product.
Safe battery practice:
Charging can be done in two ways. Some dual-18650 mods offer charging through a USB-C port on the device, which is convenient and handy when you are travelling. The more cautious approach is to remove the cells and charge them in a dedicated external charger, which is generally gentler on the cells and lets you monitor each one separately. Check the product page to confirm whether this kit has an onboard charging port and what its charging current is. Either way, use a quality charger and a reputable cable, and do not use fast chargers from unknown sources.
Battery life varies enormously with how you use the kit. At 50W to 60W on a 0.3 ohm coil, a pair of 2,500mAh cells will typically last most of a day of moderate vaping. At 100W and above the cells drain quickly and the cells work much harder, so you will want a spare pair if you vape at high power through the day.
When cells reach the end of their life, do not put them in your normal bin. In the UK, lithium cells should be taken to a battery recycling drop-off point, which you will find at most supermarkets, DIY stores and household waste recycling centres. Retailers that sell batteries are also required to take back old ones. Tape over the terminals first for safety. Never throw lithium cells into household rubbish or general recycling, as damaged cells can start fires in collection vehicles and waste sites.
A sub-ohm tank is a tank that takes coils with a resistance below 1.0 ohm. Lower resistance means more current flows through the coil at a given voltage, which generates more heat and so more vapour. Mesh coils, which replace the old coiled wire with a thin sheet of folded metal mesh, spread that heat over a much larger area. That makes them quicker to reach working temperature, more even in how they heat the cotton, and generally better for flavour than traditional coils at the same power.
What you need to know about the tank:
UK rules shape what your tank looks like. Tanks sold in the UK are limited to a 2ml capacity, and nicotine-containing e-liquid is sold in bottles of no more than 10ml. Nicotine-free liquids and shortfills can be sold in larger bottles, which is why 50ml and 100ml shortfills exist. The maximum nicotine strength for any e-liquid is 20mg/ml. The same limit applied to disposables when they were still on sale, which is one reason a 20mg nicotine salt was the usual choice for those products. For this kit, you will fill the 2ml tank more often than you would a larger overseas tank, which is a normal feature of UK-spec equipment. Never fit an oversized glass or a non-UK expansion kit to try to hold more, as it changes the product from its UK-supplied specification.
Priming a new coil properly is the single most useful habit you can build. Drip a few drops of e-liquid directly on to the cotton through the holes in the side of the coil, fit it to the tank, fill the tank, tilt the tank gently to help the liquid soak in, and let it stand for five to ten minutes before use. Skipping this step is the main cause of burnt coils in the first day of use.
Coils are consumables and should be recycled. Most UK vape shops and many household waste recycling centres accept used coils and empty vape equipment, and electrical items carrying the crossed-out bin symbol should go to a WEEE recycling point. Never put the mod itself in general waste either.
Choosing the correct nicotine strength is one of the places new sub-ohm users go wrong, and it matters more with a high-power mod than with a pod. A sub-ohm setup produces a large volume of vapour per puff. If the nicotine strength is too high, a single draw can deliver far more nicotine than you intended and cause nausea, dizziness or throat irritation. If it is too low, you will chain vape in an attempt to get enough and use more liquid than necessary.
A practical guide for freebase nicotine in a sub-ohm tank:
Nicotine salts, usually sold at 10mg/ml or 20mg/ml, are designed for low-power pod devices and low-wattage restricted draws. They are very smooth at higher strengths, which is exactly the problem in a sub-ohm tank. Putting a 20mg salt through a 70W mesh coil delivers a huge dose per puff and is likely to make you feel unwell. If you have a 10mg or 20mg salt liquid you want to use, use it at low wattage with a high-resistance coil, or save it for a pod device.
Mixing shortfills is easy once you know the maths. A 50ml shortfill sold in a 60ml bottle leaves room for exactly one 10ml nicotine shot. Add one 10ml 18mg nic shot and the final strength is about 3mg/ml. Shake it well and let it rest for a day or two before use. Always check the bottle's instructions for the specific brand, since the nicotine shot strength and the shortfill size both vary.
The UK legal maximum for any e-liquid is 20mg/ml. If you have been using a 20mg disposable and are moving to this kit, do not simply carry the number across. Start at 3mg/ml or 6mg/ml, see how you feel after a day, and adjust. Higher power gives more vapour per puff, so the same total intake happens at a much lower strength.
If you are not a current smoker or vaper, do not start. Nicotine is addictive, and these products are intended for adults who smoke and want a lower-harm alternative.
The Obelisk 200W is a specific kind of device, and it suits a specific kind of user. Matching the kit to the way you vape matters more than the headline wattage.
This kit is a good fit if you:
You may want to look at something else if you:
It is also worth being honest about where wattage stops being useful. You do not need a 200W mod to enjoy sub-ohm vaping, since most users settle between 40W and 80W. But the headroom in a dual-battery mod means the cells are working well within their limits at those settings, which tends to be kinder to battery life and means the mod stays cooler during longer sessions.
Setting up a new sub-ohm kit takes ten minutes if you follow the steps in order, and it avoids most of the problems people run into on day one.
To switch off, press the fire button five times again. To lock the button, check the manual for the specific key sequence, since it can vary. Locking is useful when carrying the device in a bag, as accidental firing can drain the cells or heat the coil with no liquid on it.
Everyday care takes a minute. Keep the tank topped up before it falls below a quarter, since running a coil dry is the quickest way to ruin it. Take regular short breaks rather than chain vaping, which gives the cotton time to re-wet. Wipe the 510 pin and the battery contacts with a dry cotton bud now and then. When changing flavour, rinse the tank under warm water, dry it fully, then fit a fresh coil. Never submerge the mod itself.
Draw gently. A slow, steady inhale of three to five seconds suits sub-ohm vaping. Fast, harsh pulls can flood the coil and cause gurgling and spit-back.
Most problems with sub-ohm kits come from the same handful of causes. Work through the likely ones before assuming the device is faulty.
If the problem remains after these checks, contact the retailer with your order number and a short description of what happens. Faults that appear in the first weeks are normally covered under your statutory consumer rights, and Geekvape equipment typically carries a manufacturer warranty on the mod itself. Coils, o-rings and glass are consumables and are usually not covered by warranty, so keep spare ones handy. Never attempt to open the mod or modify its electronics.
Assessing value on a refillable kit means looking at the whole cost of running it, not only the price on the box. The upfront price of the Obelisk 200W covers the mod and tank. After that, three recurring costs apply: coils, e-liquid and battery replacement.
A rough monthly picture for a moderate daily user:
Compared with a heavy habit on disposable vapes, a refillable kit usually works out considerably cheaper after the first month or two. A single large-puff disposable can cost several pounds and last a few days for a heavy user, and the single-use ban has removed that option for new purchases anyway. Compared with cigarettes, the running costs of a refillable kit are generally a fraction of the cost of smoking.
What you get for the money is an adjustable device with a wide wattage range, a standard 510 connector that lets you change tanks without replacing the mod, and removable batteries you can replace individually. These are the points where a dual-battery mod outweighs a closed pod system on long-term value. If one component fails, you can replace it. If a newer tank appeals to you in a year, the mod keeps working.
Where value is less clear is if you will use only a small fraction of the available power. If you know you prefer a mouth-to-lung draw at 15W to 25W, a high-wattage dual-battery mod gives you capability you will not use, and a simpler pod kit would be cheaper and easier to live with. Be honest about how you actually want to vape before you buy.
Check the current price on the product page, compare it against the price of the equivalent Aegis kit in the same Geekvape range, and add the cost of a set of cells and a charger if they are not included, so you are comparing like with like.
The market for dual-battery sub-ohm kits is crowded, and the better ones are close enough that personal preference and price often decide it. Here is a fair look at where the Obelisk 200W sits against the options most UK vapers will weigh up.
On the points that matter day to day:
The honest conclusion is that the Obelisk 200W is a competent, mainstream high-power kit rather than a niche product. If its look, price and feature set appeal to you, there is no strong reason to hold out for a rival. If you want the rugged reputation of the Aegis line or a different interface, those alternatives are worth a look before you buy.

Geekvape (Geek Vape) is best known for its waterproof, shock-resistant Aegis hardware — chosen by vapers who need a device that survives rough use. Its pod kits and AIO builds share the same tough-first engineering as the mods.
For a sub-ohm kit like this, most people use 3mg/ml or 6mg/ml freebase nicotine, and heavy former smokers sometimes go up to 9 or 12mg/ml at lower wattage. Nicotine salts at 10mg/ml or 20mg/ml are designed for low-power pod devices and are too strong for a 60W sub-ohm tank. The UK legal limit for any e-liquid is 20mg/ml.
The kit runs on two removable 18650 cells. You can charge them in an external charger, which is the more cautious approach, or through the mod if the product page confirms an onboard charging port. At a typical 50W to 60W, a good pair of high-drain cells usually lasts most of a day of moderate use, and less if you vape at 100W or above.
On most UK kits of this type the cells are sold separately, so check the product page for this specific listing. If they are not included, buy two matched, genuine high-drain 18650 cells rated for at least 20A continuous discharge, such as the Samsung 25R, LG HG2 or Molicel P26A, and never mix brands or ages in the same mod.
The variants of this kit are colourways, such as black, blue, gunmetal and silver, and they perform identically, so choose on looks and availability. The flavour comes from the e-liquid you put in the tank, so you can change it as often as you like. Rinse the tank and fit a fresh coil if you switch between very different flavours.
Most daily users get between one and three weeks from a mesh coil, depending on wattage and how sweet the liquid is. Replace it when the flavour turns flat or burnt, when you see gurgling or leaking that does not clear after cleaning, or when the cotton looks dark and dirty. Prime every new coil properly to get the full life from it.
A refillable kit usually costs less per day than a large-puff disposable once you have bought the equipment, and single-use vapes can no longer be sold in Great Britain anyway. Your running costs are coils, e-liquid and eventual battery replacement. If you only want a small, simple device for a few puffs a day, a pod kit may suit you better.
It suits adult smokers and vapers who want big vapour, strong flavour and adjustable power, and who are happy to handle 18650 batteries safely. It is not ideal if you want a tight cigarette-like draw, a very small device or a no-fuss built-in battery. Vaping is not recommended for non-smokers or anyone under 18, and sales to under-18s are illegal in the UK.
Orders are dispatched within the UK and you will receive a tracking link once your parcel ships. Delivery times depend on the service you choose at checkout, and the checkout shows the available options and costs before you pay. Lithium cells are shipped by sellers in line with UK carrier rules, so a battery order may use a specific service.
Geekvape equipment normally carries a manufacturer warranty on the mod, and your statutory rights under UK consumer law apply to faulty goods. Coils, o-rings and glass are consumables and are generally not covered. If something goes wrong, contact us with your order number and a short description of the fault, and keep the packaging until you are sure the kit is working properly.
