Geekvape Max 100 Kit overview

The Geekvape Max 100 Kit is a refillable pod mod kit from Geekvape, the Shenzhen manufacturer best known for tough, shock-resistant hardware in its Aegis range. It is not a disposable. You fill a pod with e-liquid of your own choosing, fit a mesh coil, load a high-drain battery and vape at a wattage you set yourself. With a ceiling of 100W it sits at the powerful end of the pod category, closer in output to a compact box mod than to the small, low-wattage pods that most people picture when they hear the word.

That positioning matters in the UK. The ban on single-use vapes that came into force in June 2025 pushed a large number of adult smokers and existing vapers towards reusable hardware, and a kit like this one is the logical destination for anyone who wants to keep the throat hit or the vapour volume of a disposable without putting a lithium battery in the bin every few days. A refillable kit costs more on day one, then settles into the lower running costs of bottled e-liquid and the occasional replacement coil.

This guide is written for UK buyers and goes through the kit in plain terms: what you get, how it performs, what to put in it, how to look after it, what tends to go wrong and how to fix it, and how it stacks up against rivals at a similar price. We have tried to be straight about the weak points as well as the strong ones, because a 100W pod kit is not the right purchase for everybody.

Some quick context before the detail:

• Category: refillable pod mod kit with variable wattage, suited to restricted direct-to-lung and looser mouth-to-lung styles depending on the coil you fit.
• Audience: adult smokers moving away from cigarettes, and existing vapers who have outgrown low-powered pods. It is not intended for non-smokers or anyone under 18.
• Range: the product listing offers six variants in the family. For a kit these are mostly finishes and colourways rather than flavours, so choose on looks and then pick your e-liquid separately.
• Running costs: e-liquid, coils and a spare battery, rather than a whole new device each time the puffs run out.

Specifications for kits in this class can change between production batches and between regional versions, so treat the figures in this guide as a reliable steer and check the product page and the leaflet in the box for the final word on the unit you receive.

What is in the box and key specifications

Contents vary slightly by retailer and batch, but a Geekvape Max 100 Kit of this type normally includes the items below. Always confirm against the listing before you order, particularly on whether a battery is supplied, because many kits in this class ship without one.

• The Max 100 pod mod device
• A refillable pod with a mesh coil already fitted
• Usually at least one spare mesh coil
• A USB-C charging cable
• A user manual, warranty card and safety leaflet

The headline specifications, as typically listed for this kit, are as follows.

• Output: variable wattage from the low single digits up to a 100W maximum.
• Power source: a single removable high-drain lithium-ion cell in the 18650 class. Some versions of the device also accept a larger 21700 cell, so check the manual for the sizes yours supports.
• Pod capacity: 2ml for UK sale. UK rules cap refillable tank size at 2ml, so if you see a larger figure quoted in overseas specifications, a pod sold here will be the smaller capacity.
• Coil system: Geekvape B Series style mesh coils, with lower-resistance options for higher wattage and higher-resistance options for tighter draws. Confirm the exact resistance fitted on your listing.
• Charging: USB-C, which means the same cable as most modern phones and no proprietary lead to lose.
• Display: a compact screen showing wattage, battery level and coil status.
• Protection circuits: short-circuit, low-resistance, over-discharge, over-time cut-off and overheat protection, which is standard for regulated devices from established makers.
• Durability claims: the Aegis family is marketed as shockproof, dustproof and water resistant, with an IP68 rating on the range. Treat that as protection against drops, pocket dust and rain, not an invitation to submerge the device with a battery installed.

One point on puff counts: a refillable device does not have a fixed puff count the way a disposable does, because the figure depends on pod size, e-liquid, wattage and how you draw. We give realistic estimates in the performance section rather than quoting a marketing number.

Finally, an age note that applies to every product on this site: vaping products are for adults aged 18 and over only, and are intended for people who already smoke or vape.

Performance and puff delivery

Performance on a variable-wattage kit depends on what you ask of it. The Max 100 can be set to a gentle 20 to 30W for a tight, cigarette-like draw with salt nicotine, or pushed to 60 to 100W with a low-resistance mesh coil for a looser, warmer and noticeably more vapour-heavy draw. Most owners settle somewhere in the middle for daily use, and that middle ground is where this class of device is generally happiest.

Low wattage, roughly 15 to 30W. Paired with a higher-resistance coil, this is mouth-to-lung territory. The draw is tight, vapour is modest, flavour is concentrated and nicotine delivery from a 10mg or 20mg salt liquid is efficient. A pod fill lasts longest here, and the battery will carry you through a long day.

Mid wattage, roughly 40 to 70W. With a mesh coil in the lower resistance range this is restricted direct-to-lung vaping. Vapour is warm and dense, flavour is full, and the throat hit softens, which is why lower-strength freebase nicotine of around 3 to 6mg suits this range. Both e-liquid and battery consumption climb quickly compared with low wattage.

High wattage, roughly 80 to 100W. At the ceiling the kit produces hot, dense vapour and burns through liquid fast. A single cell is working hard to feed that output, so expect more heat in the device, shorter runtime and a higher risk of dry hits if your e-liquid is very thick. Most people use the top of the range occasionally rather than all day.

Mesh coils reach working temperature almost instantly, so response after pressing the button or inhaling is quick, with little of the lag you get from older round-wire coils. Depending on the version, the device fires on the inhale, on a button press or both, so check the manual for how yours behaves.

How many puffs from a pod? There is no official figure, but a sensible estimate is around 150 to 250 puffs per millilitre at higher wattages and noticeably more at low wattage, which puts a 2ml pod at roughly 300 to 500 puffs at mid power and more than that at low power. That is in the same region as many disposables claim, except that refilling costs pennies rather than the price of a new device, and nothing is thrown away.

One honest caveat: because UK pods are limited to 2ml, refills come around quickly at high wattage. If you plan to vape at 80W and above all day, you will be topping up often, and a bigger-tank device may suit you better.

Flavour profile and what to put in it

The Max 100 is a hardware product, so its flavour is whatever you pour into it. What the kit contributes is how faithfully it renders that liquid. Mesh coils have a large heating surface and spread heat evenly across the wick, which usually gives a rounder, more consistent taste than older single-wire coils and avoids the harsh patches that come from hot spots. At low to mid wattage the flavour is clear and well defined; at the top of the range, delicate flavours can flatten and sweeteners can turn slightly harsh.

The six variants in this product family are finishes rather than flavours, so you are free to buy any e-liquid you like. These are the flavour groups that tend to suit a 100W pod kit, with notes on how to set the wattage for each:

• Menthol and mint: peppermint, spearmint and menthol ice all cope well with higher wattage, and the cooling effect stays crisp at 50W and above.
• Blue raspberry and berry blends: sharp, sweet and sour profiles sit comfortably in the 35 to 60W window, where the fruit stays bright without burning the sweetener.
• Strawberry, watermelon and other juicy fruits: work across the range, and often taste best slightly below the maximum rating of the coil.
• Mango, pineapple and tropical mixes: acidic fruits can feel sharp at high power, so a mid-range setting keeps them smooth.
• Cola, energy drink and soda styles: these carry a lot of spice and acidity and are usually happiest at moderate wattage.
• Tobacco and classic blends: best at the lower end, around 20 to 35W, with a salt nicotine liquid and a higher-resistance coil for a cigarette-like draw.
• Vanilla, custard and dessert flavours: keep the wattage on the low side, as heavy creamy liquids tend to cook and leave a dull, sticky taste when pushed.

PG and VG ratio. A 50/50 blend is the safe all-rounder and wicks quickly into a mesh coil at any wattage. Higher-VG liquids give thicker clouds but can wick slowly at high power, which raises the risk of dry hits, so if you choose a 70VG liquid, start a little below the coil's rated range and work up. Nicotine salt liquids are typically 50/50 and are best kept for lower wattages.

Flavour ghosting. Pods and coils hold on to the taste of whatever has been in them. If you switch between very different profiles, such as menthol one day and cola the next, rinse the pod and use a fresh coil or a dedicated pod for each family, because residual menthol will otherwise leak into everything that follows it.

Design, build quality and ergonomics

Geekvape built its name on tough devices, and the Max 100 follows that line. The body is a rugged shell designed to take knocks, with a finish that stays grippy in the hand rather than slick. It is larger and heavier than the pen-style pods that fit almost any pocket, and it feels closer to a small box mod. Expect a device that sits comfortably in a jacket pocket or bag, and that is more noticeable in a tight trouser pocket.

The weight comes mostly from the removable battery and the metal and reinforced plastic used around it. That is a trade-off most people accept, because a removable cell means you can swap in a fresh one rather than waiting to recharge, and the sturdy body protects the battery compartment, which is exactly the place you want to be well built.

Controls and screen. The Max 100 uses a small display and a simple button layout so that changing the wattage becomes a quick habit rather than a menu hunt. The screen shows the wattage you have set, remaining battery and any error message, such as a coil fault or short circuit warning. In bright sunlight, small displays can be harder to read, which is true of nearly every device in this category.

Pod fit and filling. The pod should seat firmly with a distinct click and sit flush with the body. A pod that wobbles or sits proud of the shell is a sign it has not clicked fully into place and is a common cause of poor connection errors, so it is worth checking each time you refit it. Filling is done through the fill port on the pod; fill slowly, avoid the central airflow tube, and stop at or just below the maximum line so that the coil has room to breathe.

Airflow. The adjustable airflow lets you move between a tighter mouth-to-lung draw and a more open restricted direct-to-lung draw. Matching airflow to coil and wattage is the most important single adjustment you will make, since too little air at high power is a classic source of overheating and burnt flavour.

Finish and wear. Textured and coated finishes hide fingerprints better than gloss, but all painted devices pick up scuffs over time. If you carry the kit loose with keys, a silicone sleeve or small case is a sensible and cheap precaution, even with a rugged shell.

Battery, charging and safety

The Max 100 is built around a single removable lithium-ion cell rather than a sealed internal battery. That gives you two big advantages. First, you can carry a charged spare and swap it in when the first one runs low. Second, when a cell eventually wears out you replace the cell, not the entire device, which is better for your wallet and for the amount of electronic waste you generate.

Choosing a cell. The device needs a genuine high-drain battery from a reputable brand, rated for continuous discharge of at least 20A and preferably 25A or more, because a regulated 100W device pulls a lot of current at the top of its range. Cheap unbranded cells with inflated capacity claims are a safety risk and a false economy. Buy from a reputable UK retailer, never from an unknown marketplace seller, and check the cell size against the manual. Capacity is typically in the range of 2,500 to 4,000mAh depending on the format.

Runtime. A reasonable expectation for a good cell at mid wattage is a full day of moderate use. At 80 to 100W, runtime drops sharply and the cell and the device will both run warm. If you vape heavily at high power, carry a second cell.

Charging. The device charges over USB-C. A 5V wall adapter or a computer port is fine. Charging inside the device is convenient, but for the long life of removable cells many experienced vapers prefer an external charger that stops at 4.2V and gives a more controlled charge. As a rough guide, charging a 3,000mAh cell inside the device takes a couple of hours; check the manual for the maximum charge rate the device supports.

Safe handling.

• Never carry loose cells in a pocket with coins or keys. Use a plastic cell case.
• Do not charge unattended or overnight, and stop using any cell with torn wrap, dents or signs of swelling.
• Do not mix old and new cells or different brands in the same device over time; always use a matched, healthy cell.
• Keep the device out of direct sun, hot cars and damp places.

Recycling in the UK. Never put batteries or devices in household bin or normal recycling. Lithium cells start fires in bin lorries and waste plants. Take dead cells and old devices to a household waste recycling centre, or use the battery recycling boxes provided by many supermarkets and the vape shops that now offer take-back schemes. Spent coils and empty pods can often be recycled alongside small electricals at the same places, and the wick material is minimal.

Coil and mesh technology

The coil is the heart of any pod kit and the biggest influence on how the Max 100 feels to use. This kit uses mesh coils from Geekvape's B Series family. Instead of a single round wire wrapped around cotton, a mesh coil is a thin sheet of perforated metal, folded and pressed against a cotton wick. That design has several practical consequences.

• Larger heating area. The mesh heats a wide stretch of wick at once, which produces more vapour at a given wattage and smooths the flavour.
• Fast ramp-up. The thin material reaches vaping temperature in a fraction of a second, so response is crisp.
• Even heat. Hot spots are less common, which cuts down on the burnt taste that plagues cheaper coil designs.
• Longer working life. With sensible wattage and clean liquid, a mesh coil typically lasts one to three weeks of moderate use, though sweet liquids shorten that.

Resistance and wattage. Coil resistance is measured in ohms. A lower-resistance coil lets more current flow, allowing higher wattage and more vapour, and calls for lower nicotine strength. A higher-resistance coil needs less power and suits a tighter draw and higher nicotine strengths. The Max 100 is designed to read the coil automatically and suggest a power range, but you can adjust inside the range printed on the coil casing. Staying within that range is the main way to extend coil life.

Priming a new coil. This step is where most early problems begin. After fitting a new coil, drip a few drops of e-liquid directly on the cotton through the wicking holes, fill the pod, and let it stand for five to ten minutes before you use it. Then take a few gentle draws at low power before moving up. Skipping this is the most common cause of a burnt first pod, which can ruin a coil in a few puffs.

When to replace a coil. Replace the coil when the flavour turns dull or burnt even with fresh e-liquid, when vapour thins out, or when you hear gurgling or notice crackling. A coil that tastes bad cannot be rescued by cleaning, and pushing on only wastes liquid.

Compatibility. Use only the coil family listed for the device. Mixing coils from another range can cause a poor fit, leaking or an error message. Buy replacements from the same retailer as the kit to avoid counterfeit coils, which are common for popular Geekvape lines.

Nicotine strength guidance

Choosing the right nicotine strength matters more on a 100W kit than on any low-powered pod, because power and strength interact. Higher wattage produces more vapour per puff, so a given strength delivers more nicotine and a harsher throat hit. In the UK, e-liquid is capped at 20mg/ml nicotine (2%) and bottles at 10ml, and the same 20mg cap applied to the single-use vapes that are no longer on sale. Nothing sold here exceeds that limit, but that does not mean the top of the range is right for a powerful device.

Match the strength to the way you vape.

• Low wattage, tight draw, higher-resistance coil (roughly 15 to 30W): nicotine salt liquids at 10mg or 20mg work well. Heavy smokers who want a clear step down from cigarettes usually start at 20mg and move down as they cut back; lighter smokers do better at 10mg.
• Mid wattage, restricted direct-to-lung (roughly 40 to 70W): choose lower-strength freebase liquid, typically 3 to 6mg, or a low-strength 5 to 10mg salt if you want a smooth hit. The extra vapour volume means you take in nicotine quickly even at modest strengths.
• High wattage (80W and above): stay at the low end, around 0 to 3mg freebase, or a very low-strength salt. Combining 20mg salt nicotine with 100W produces a harsh hit and a risk of taking in more nicotine than you want, with symptoms such as nausea, dizziness, sweating and headaches.

Salt versus freebase. Nicotine salt is smoother at higher strengths and is built for low-power devices. Freebase nicotine is harsher but is the usual choice at higher power and lower strengths. At the top of the Max 100's range, freebase at a modest strength is the more comfortable pairing.

Coming from disposables. Many disposables sold in the UK before the ban used 20mg salt liquid at around 10 to 15W of effective power. If that is your starting point, run the Max 100 at 20 to 30W with a 20mg or 10mg salt liquid and a higher-resistance coil, and treat the higher wattages as a later experiment. Starting at 80W with 20mg is the most frequent mistake new users make.

Coming from cigarettes. If you are a daily smoker, switching fully to vaping is easier when your nicotine is matched to your habit. A 20mg salt liquid at low wattage is the closest match for heavier smokers; lighter smokers can use 10mg. Review after two weeks and drop a strength once you notice you are drinking more than you need.

If you have a health condition, are pregnant or are on medication, speak to a pharmacist or GP before switching, and consider the NHS stop smoking service, which supports people using vaping to quit.

Who the Max 100 is for, and who should skip it

A powerful, rugged pod kit is a good match for some vapers and a poor match for others. Be honest with yourself about which group you are in.

It suits:

• Disposable vapers moving to reusable kit. The ban left many people looking for a refillable device that still delivers satisfying vapour, and a 100W pod with a mesh coil gives them a way to dial in the draw they are used to.
• Adult smokers who want a stronger switch. At low wattage with salt nicotine, it is a capable cigarette replacement; at higher settings, it gives a more substantial draw than a basic starter pod.
• Vapers who like to tinker. Adjustable wattage and airflow, plus a choice of coils, reward people who want to tune their vape.
• People who work or play outdoors. The rugged build and splash resistance suit tradespeople, walkers, festival-goers and anyone who is hard on their kit.
• Heavy daily users who like having a spare removable battery.

You may want to skip it if:

• You want something tiny and discreet. The Max 100 is a hefty device, and a slim MTL pod will be easier to carry.
• You are brand new to vaping and want zero fuss. Wattage settings, coil priming and battery choice add complexity. A simple closed-pod system with pre-filled pods is easier on day one.
• You never want to buy a battery or charger. If the kit does not include a cell, you need to budget for one and a safe way to charge it.
• You only vape occasionally. A 100W kit is overkill for a puff or two a day, and the weight and cost are hard to justify.
• You are a non-smoker. Vaping is intended for adults who already smoke or vape, not for people who have never used nicotine. It is not risk free.
• You need a large tank. UK pods top out at 2ml, so heavy vapers who like to fill once a day should consider this honestly.

If you sit in the middle, the kit is easy to run at low settings first, then step up as you learn how coil, wattage and liquid work together. The risk is not in the hardware; it is in running it too hot too soon.

How to set up and use the Max 100

Setting up the kit takes a few minutes. Follow the order below and you avoid most of the problems that new owners run into.

• Step 1, unpack and inspect. Check the device, pod and coils for damage, and make sure the contacts are clean. Read the safety leaflet and note the supported battery size.
• Step 2, fit the battery. Open the battery compartment, check the polarity marks and insert a genuine high-drain cell with the positive end the right way round. Close the cover until it sits flush. Never use a damaged cell.
• Step 3, prime the coil. Place a few drops of e-liquid on the exposed cotton of a new coil, then fit it in the pod and press it home.
• Step 4, fill the pod. Open the fill port, tilt the bottle and fill slowly to just below the maximum line. Avoid the central tube, close the port and wipe away spills. Let the pod sit for five to ten minutes so the cotton saturates.
• Step 5, seat the pod. Push the pod into the body until it clicks, and check it sits flush.
• Step 6, switch on and set the power. Press the fire button the number of times given in the manual to switch on, then set the wattage. Start low, in the range printed on the coil, and take a few gentle draws before stepping up.
• Step 7, adjust airflow. Open the airflow for direct-to-lung and a cooler draw, close it for a tighter mouth-to-lung draw. Reduce wattage as you close the airflow.

Daily habits that protect the kit.

• Top up the pod before it runs fully dry. Vaping on an empty or nearly empty pod burns the wick within a few puffs.
• Use short draws of two to four seconds with a pause between them. Chain vaping at high power overheats the coil and shortens its life.
• Wipe the pod contacts and the device connector with a dry cotton bud once a week. Residue here causes error messages.
• Lock the device when it is in a bag or pocket so it cannot fire by accident. Check the manual for the lock sequence.
• Store the device upright where possible, and remove the battery if you will not use it for a few weeks.

If the device ever feels unusually hot, smells of burning, or the battery swells, stop using it, remove the cell if it is safe to do so, and take it to a recycling point. Do not carry on regardless.

Troubleshooting common problems

Most problems with pod mod kits are caused by a small number of things: a poorly primed coil, a poorly seated pod, a tired battery or wattage set outside the coil's range. Work through the list below before you assume the device is faulty.

• Burnt or harsh taste. Usually a dry or worn coil. Check the liquid level, let the pod rest, lower the wattage and open the airflow. If the taste stays burnt after a refill and a rest, fit a new coil. Sweet liquids and heavy chain vaping wear coils out faster.
• Leaking from the pod or the base. Causes include overfilling, a loose pod or coil seal, a very thin liquid, or changes in air pressure on a flight or in the car. Wipe the pod, check that the coil is pressed fully home, and fill to just below the line. Carry the kit with the pod empty when travelling.
• Gurgling or spitting. Condensation and flooding in the airflow. Remove the pod, blow through the mouthpiece to clear it, then wipe the base. Lowering the airflow slightly can help.
• No vapour or a weak puff. The wick may not be saturated, the pod may be empty, or the coil may be spent. Prime again, refill and try. If the device is draw-activated, check the airflow is not blocked.
• Error message such as check coil, no pod or short circuit. Take the pod out, wipe the contacts on both the pod and the body with a dry cotton bud, and refit it. If the message continues, try a new coil, because a failed coil causes the same message.
• Device will not switch on or charge. Check the polarity of the cell, try a different battery and a different cable and adapter, and clean the USB-C port with a dry wooden toothpick, not metal. If it still fails, contact the retailer.
• Battery drains quickly. High wattage, a worn cell or an undersized cell will all shorten runtime. Drop the wattage, replace an old cell, and use a cell with a suitable discharge rating.
• Device gets hot. Normal in short bursts at high power, but persistent heat means the wattage is too high for the airflow, the cell is struggling or the coil is faulty. Lower the power and open the airflow.
• Pod will not click in. Check for dried liquid on the connector, and make sure the coil is seated and the pod is the right way round. Do not force it.
• Sticky, cracked or crackling mouthpiece. Wash the mouthpiece in warm water, dry it fully and avoid soaking the electronic contacts.

If you have worked through the checks and the device still misbehaves, stop using it, keep your proof of purchase and contact the shop. Faulty items are covered by consumer law, and a short description of the fault with a clear photo speeds up a resolution.

Value for money and how it compares with rivals

Value on a refillable kit is about the total cost over a few months, not the sticker price. The Max 100 asks for more at the till than a disposable did, and may need a battery on top, but the cost per day falls rapidly once you start refilling.

A simple running-cost picture. A 10ml bottle of nicotine salt or freebase liquid is often priced in the range of a few pounds, and will fill a 2ml pod around five times. At moderate use, that bottle might last four to seven days. Add a mesh coil every one to three weeks, and the weekly running cost is typically well below what a regular disposable user spent. The saving rises the more you vape, and the less waste you create.

What you are paying for. Rugged construction, a wide wattage range, a removable cell and the ability to choose your own liquid. What you are not paying for is a throwaway shell. Where the Max 100 is weaker on value is for people who need a large tank, a battery that is included at no extra cost or the smallest possible pocket footprint.

Honest comparisons.

• Vaporesso XROS series. Smaller, lighter and usually cheaper, and focused on mouth-to-lung vaping at much lower power. A strong choice for tight-draw, salt nicotine users who value discretion, but it cannot reach the Max 100's higher-power, cloud-heavy settings.
• Uwell Caliburn series. Compact, simple and easy to run for ex-smokers. Again lower power and mainly mouth-to-lung, so it is gentler on the learning curve but narrower in what it can do.
• Vaporesso GTX Go 80 and similar 80W-class pods. These are closer rivals, with built-in batteries and comparable output. A sealed battery is convenient for charging but cannot be swapped on the go, which is where the Max 100's removable cell has the advantage.
• Voopoo Drag series and Smok Nord 5. Popular mid-power options with good flavour and large coil ranges. They are fair alternatives on features and price, and the choice often comes down to which design, screen and coil system you prefer in the hand.
• Disposables and closed pod systems. Disposables are now illegal to sell in the UK, and closed pods cost more in the long run for heavy users than refilling a kit.

Verdict. The Max 100 Kit makes sense if you want a rugged, powerful and flexible reusable device and are willing to manage a battery and a coil. It makes less sense if you want the smallest, simplest and cheapest way to start. For adult smokers and vapers who fit the first description, it is good value over the long term, especially when bought from a retailer that stocks genuine coils and offers clear returns terms.
