GeekVape Aegis M100 Starter Kit overview

The GeekVape Aegis M100 Starter Kit is a refillable pod mod kit from Geekvape, a manufacturer whose Aegis range has built its following on tough, travel-friendly hardware rather than on flashy looks. The M100 name points to a power ceiling in the region of 100W, which places this kit at the upper end of what most people want from a pocketable device: enough output to run a proper mesh coil at a comfortable temperature, in a body small enough to carry in a jacket pocket without feeling like you are hauling a brick around. This guide goes through what the kit does, who it suits, how to run it, and where it sits among the alternatives sold in the UK, so you can decide with the facts in front of you rather than the marketing copy.

A note on specifications before we go further. Manufacturers revise batteries, pod sizes and coil bundles between production batches, and retailer listings sometimes lag behind. Where this page quotes a figure we say whether it is a firm number or a typical value for kits in this class, and we recommend checking the specification table on the product page and the printed insert in the box for final figures. That is slower than copying a number from a press release, but it means you will not be caught out by a detail that changed.

The important thing to understand about a kit like this is that it is a different proposition from a disposable. You buy the device once, you fill it with e-liquid of your choosing, and you replace the coil every so often. There is no puff count printed on the side counting down to a bin, and the running cost per day is a fraction of what a single-use product costs. The trade-off is that you do a little more yourself: filling, priming, occasionally cleaning, and choosing a nicotine strength that suits you. For anyone who has been through a few disposables and wants something more controllable and cheaper to run, that trade is usually well worth making.

Seven variants sit in this product family. For a hardware kit those variants are colour finishes rather than flavours, so you pick the look you like and then choose your own e-liquid separately. We cover the flavour side in its own section below, because it matters more than most buyers expect.

Specifications and what to expect in the box

The figures below are the ones we can stand behind for a 100W-class Geekvape pod mod kit sold into the UK market. Treat the battery and resistance ranges as typical values for this category and confirm the exact numbers against the specification table on the listing before you rely on them.

• Device type: refillable pod mod kit with variable wattage output, adjustable up to roughly 100W as the M100 name indicates.
• Battery: built-in rechargeable lithium-ion cell. Kits of this size usually carry a battery somewhere in the 2,000 to 3,000mAh range, which is the sweet spot between pocket size and a full day of mixed use.
• Charging: USB-C, so the same cable that charges your phone or tablet will normally do the job.
• Pod capacity: refillable pod holding 2ml of e-liquid, which is the maximum tank size permitted for nicotine vaping products sold in the UK.
• Coils: replaceable Geekvape mesh coils in the sub-ohm range, typically between about 0.15 and 0.4 ohm depending on which coil is fitted.
• Output control: wattage adjustment through the fire button and a small display, with an adjustable airflow slider or ring on the pod.
• Protections: the usual set of short-circuit, over-temperature, over-discharge and low-resistance cut-offs that responsible manufacturers build into regulated devices.
• Colour options: seven finishes across the family. Available colours depend on stock, so use the variant selector on the product page.

In the box you should expect the device itself, a refillable pod with a coil already installed or supplied alongside it, a USB-C charging cable, a quick-start manual and a warranty card. Some kits include a spare coil as well. If anything is missing when you open the box, contact us with your order number and a photo of the contents and we will sort it out.

One detail worth explaining is the 2ml pod. Some Geekvape kits are sold overseas with a pod or tank of 4ml or 5ml and a smaller version supplied for the UK. British rules limit refillable tanks on nicotine vaping products to 2ml and e-liquid bottles to 10ml, so a UK kit will come with a 2ml pod. That limit is not a flaw in the product. It is simply the legal size, and it means you will refill more often than someone using a larger tank would, which is something to factor in if you plan to take this device on long days out.

Performance and vapour delivery

Power is the headline number on a kit like this, but it is worth being honest about how most people actually use it. A 100W ceiling does not mean you should run the device at 100W. A mesh coil designed for this kind of device usually has a recommended wattage window printed on the coil itself, and the sensible place to start is at the lower or middle part of that window, then nudge upwards in small steps until the flavour and vapour density feel right. For many people that lands somewhere between 40W and 70W. Going beyond that tends to produce hotter vapour, faster e-liquid consumption and a shorter coil life, with only a modest gain in flavour.

Where the extra headroom earns its keep is in consistency. A device that is comfortably within its limits delivers the same vapour on the tenth puff of a session as on the first, without the battery sagging or the coil struggling to keep up. Mesh coils also heat up quickly, so the delay between pressing the fire button and getting vapour is short. You should not need to hold the button down for a second or two to get going, which is a frustration with some older round-wire coils.

Airflow is the second half of the performance story. This kit is built around a restricted direct-to-lung or restricted lung style of inhaling, which means a slightly looser draw than a traditional cigarette-style pull but not the wide-open airflow of a high-power rebuildable tank. Tighten the airflow if you want a warmer, more concentrated vapour with more throat hit from your nicotine salt. Open it up for a cooler, airier draw. It is worth experimenting with both the airflow and the wattage together, because the two interact. Opening the airflow cools the vapour and can make a flavour feel thinner, which you can compensate for with a small increase in power.

As for how long a fill lasts, there is no puff count to quote because this is a refillable device and the answer depends on power, airflow and how you draw. As a loose guide, a 2ml fill at moderate wattage lasts most users somewhere in the region of a few hundred puffs, with heavy users at higher wattage emptying it sooner. Treat that as an estimate rather than a promise. If you want the most economical use of your e-liquid, run the coil at the lower end of its range, because lower power uses less liquid per puff.

Compared with a prefilled pod device, you will notice a step up in flavour definition and vapour volume, and you will notice that you control it. That control is the point of buying a kit rather than another single-use product.

E-liquid and flavour: what to put in your Aegis M100

A starter kit ships empty, so the flavour you get is entirely down to the e-liquid you choose. That is an advantage, because you are never locked into a single taste, but it also means the first bottle you buy matters. The seven variants of this kit are colour finishes only. Flavour is a separate decision, and mesh coils reward a bit of thought about what you pour in.

Mesh coils have a large surface area, which gives sharp, well-defined flavour and handles most liquid styles well. Here are some popular directions that suit this type of device:

• Menthol and mint: a clean, cooling option that lets the mesh coil show off its crisp delivery. A good everyday choice for ex-smokers.
• Blue raspberry ice: sweet and tangy with a cold finish, one of the most popular profiles in the UK.
• Watermelon ice: light, juicy and refreshing, easy to vape through a long day.
• Strawberry and cream or strawberry ice: dessert-leaning and fruit-forward, with a smooth finish.
• Mango: a rounded tropical flavour that comes across clearly at moderate power.
• Cola: a fizzy, slightly spiced profile that suits warmer vapour.
• Tobacco: a dry, toasted tobacco style that appeals to people moving away from cigarettes who want a familiar note.
• Blackcurrant menthol: a darker berry with a cooling backbone, a favourite with menthol fans who want a bit of fruit.

Two practical points about e-liquid matter more than the flavour name. The first is the base ratio. Liquids are sold as a blend of propylene glycol (PG) and vegetable glycerine (VG). A 50/50 blend gives a stronger throat sensation and carries flavour well. A 70/30 VG-dominant blend gives a smoother, thicker vapour. Both work in this kind of kit, but very thick liquids can be slow to wick through some coils, so if you notice dry hits with a high-VG liquid, a 50/50 blend or a slightly higher wattage may help.

The second is that sweet liquids leave residue on the coil faster than menthol or tobacco styles, so a coil running dessert flavours may need replacing a little sooner. If you switch between very different flavours, flush the pod with warm water, let it dry fully and fit a fresh coil when changing from a strong menthol to a fruit, otherwise you will get a muddled taste from the old liquid still sitting in the cotton. Keep a separate pod or coil for strongly flavoured liquids if you swap often.

Design and build quality

Geekvape's Aegis family is known for a rugged approach to device design. The brand's pitch has long been devices that cope with everyday knocks, with a rated resistance to water, dust and shock on many models in the range. We recommend checking the product listing to confirm the exact protection rating of this kit, but the design philosophy is clear: this is a device intended to survive a pocket, a rucksack and the occasional drop, not to sit politely on a desk.

In practice, the body of a kit like this is normally built around a metal alloy chassis with a textured or coated outer finish. That gives it weight and a reassuring solid feel. It also means the device is a touch heavier than a plastic pod system, which most people read as quality but some find noticeable in a small pocket. The textured grip is not just for show. It stops the device sliding out of damp hands and resists the fine scratches that smooth anodised finishes pick up quickly.

The pod usually seats onto the body with a magnetic or snap connection and a positive click. Check that it sits fully flush after every refill, because a pod that is not completely seated is the number one cause of a no-atomizer or check-atomizer message. The fire button should be firm enough to avoid accidental presses in a pocket but responsive enough to fire first time. If your unit has a lock function, which most devices of this type do, use it whenever the device is in a bag.

The small display shows the information you actually need, which is usually the wattage setting, battery level and the resistance of the installed coil. It is not a large touchscreen and does not pretend to be. That restraint is a benefit in a robust device, because fewer fragile parts mean fewer things to go wrong.

Where you may find fault is in the finish itself. Coated and textured surfaces hide wear well, but the corners of any metal device will eventually show use if you carry it loose with keys. A cheap silicone sleeve costs very little and protects the colour you chose. The seven colour variants in this family let you pick something that matches your taste, from understated darker tones to brighter finishes, and since the colour does not affect performance, pick the one you will be happy to see every day.

Battery and charging

The built-in battery is what lets a device of this size run a mesh coil at sensible power. Kits in the 100W class typically carry a cell in the 2,000 to 3,000mAh range, and that capacity is what determines how long a day you get. We would encourage you to check the exact milliamp-hour figure on the listing, since it varies between hardware revisions.

How long it lasts depends on how you vape. At 45W to 55W with normal use, most people with a battery of this class get through a working day and often a little beyond. Push the wattage towards the maximum, vape continuously, or use the device in cold weather and you will see the battery drain noticeably faster. Lithium-ion cells lose capacity in cold conditions, so a device kept in an outer coat pocket on a winter morning can behave as though the battery is weaker than it is. Keep it in an inside pocket and it will perform more consistently.

Charging is by USB-C. A few sensible habits will keep the battery healthy for longer:

• Use a reputable charger and cable. A decent phone charger rated at 5V is fine. Avoid very cheap unbranded adaptors, which can deliver unstable power.
• Do not leave the device charging unattended overnight, and do not charge it on a soft surface such as a bed or sofa where heat cannot escape.
• If the device becomes hot while charging, unplug it and let it cool before using it again.
• Avoid draining the battery to zero regularly. Topping up when it reads somewhere around 20 percent is kinder to the cell than running it flat every time.
• If you are storing the device for a few weeks, leave it at a partial charge rather than full or empty, and keep it somewhere cool and dry.

Expect a full charge to take somewhere between one and two hours on a normal USB-C charger, with the exact time depending on the charging current the device accepts. Lithium-ion batteries wear with use, and after several hundred full charge cycles the capacity will be gradually reduced. For a typical user that is a couple of years of service, which is long enough to get good value from the kit.

If you travel by air, a vape with a built-in battery belongs in your hand luggage, not in the hold, with the fire button locked and the pod empty or the liquid sealed, since pressure changes can push e-liquid out of a filled pod.

Coil and mesh technology

The coil is the heart of any vape and the part you will replace most often. Geekvape's mesh coils use a flat sheet of fine mesh wire in place of a conventional round wire wrapped around cotton. The advantage is surface area. A mesh sheet contacts far more of the cotton wick at once, which spreads heat more evenly across the liquid. In use that tends to mean quicker ramp-up, more consistent flavour and a lower chance of a hot spot burning part of the cotton.

Coils are rated by their resistance in ohms and by a recommended wattage range. A lower resistance, such as 0.15 ohm, generally suits higher power and gives denser, warmer vapour. A higher resistance, such as 0.4 ohm, suits lower power and is a little more economical on both battery and liquid. Which one comes installed in your kit depends on the bundle, and a spare coil of a different resistance gives you an easy way to find your preferred style. Always use coils that the manufacturer lists as compatible with this specific pod. A coil from a different system may fit physically but run incorrectly, which risks poor flavour or a damaged device.

Getting the most from a coil comes down to preparation and habit:

• Prime the coil: before first use, drip a few drops of e-liquid directly onto the exposed cotton through the coil's wicking holes, then fill the pod and wait five to ten minutes. This stops the cotton firing dry, which is the commonest cause of an instantly burnt coil.
• Start low: use the lower end of the recommended wattage for the first few puffs, then increase gradually.
• Take short puffs: three to four seconds is plenty. Very long draws superheat the coil and starve it of liquid.
• Keep the pod topped up: never let the liquid fall below the wicking holes, because a coil sitting in air is a coil being damaged.

How long a coil lasts is not fixed. Typical lifespan is somewhere between one and three weeks of regular use, shorter if you vape sweet, dessert-style liquids at high power, and longer if you vape menthol or tobacco at modest wattage. You will know it is time to replace the coil when the flavour turns flat or slightly burnt, when you taste a faint scorched note even with a freshly filled pod, or when vapour production drops noticeably. Do not try to push a failing coil further. It will not recover and the taste is unpleasant.

Budget for coils as a running cost. A multipack is usually the most economical way to buy them, and keeping a spare in a drawer saves you from being caught short.

Nicotine strength guidance

Choosing the right nicotine strength is the single biggest factor in whether a kit like this feels satisfying or harsh. In the UK, nicotine e-liquid is capped at 20mg per ml, and that cap applies to every legal nicotine vaping product, including the former disposables market. Single-use disposable vapes have not been legal to supply in the UK since 1 June 2025, which is a significant reason refillable kits like this one have taken over. The 20mg ceiling remains the strongest liquid you can legally buy, and for many people it is stronger than they need.

There are two main types of nicotine in e-liquid, and the one you choose should match your power setting:

• Nicotine salts: smoother at a given strength, and designed to be used at lower power. They deliver nicotine quickly and with less throat harshness, so they suit lower wattage and a more restricted draw. Common strengths are 10mg and 20mg.
• Freebase nicotine: the traditional type, harsher on the throat as strength rises, and generally better suited to higher power and more open airflow, where lower strengths such as 3mg or 6mg are normal.

A rough guide, offered for general information and not as medical advice, runs as follows. Someone who has been smoking a pack a day and wants a close replacement is often most comfortable with a 20mg nicotine salt, run at the lower end of the wattage range with tighter airflow. Someone smoking lighter, or who has been vaping for a while and is cutting down, often settles at 10mg salt. If you plan to vape at higher power with open airflow and want large clouds, a low-strength freebase liquid at 3mg to 6mg is a better match, because a high-strength liquid at high power delivers a lot of nicotine very quickly and can feel overwhelming.

Do not run a 20mg salt at the top of the wattage range. The combination produces very harsh vapour and a much larger dose of nicotine per puff than the strength suggests. If a liquid feels too strong, the answer is a lower strength or a lower wattage, not struggling through it.

A few firm points. Nicotine is addictive. This kit is for adults aged 18 and over, and for current smokers or vapers. If you do not currently use nicotine, do not start. If you are pregnant, have a heart condition or take medication, speak to a pharmacist or your GP before using nicotine products. Free local stop smoking services are available across the UK and are worth using alongside vaping if your goal is to quit completely.

Who the Aegis M100 suits, and who should skip it

No device suits everyone, and a clear view of who gets the most from this kit saves money. Here is how we see it.

This kit is a good fit if you are:

• A smoker or former smoker switching to vaping who wants a step up from prefilled pods and the freedom to pick your own liquid.
• Someone moving on from disposables, whether because of the ban or because the cost of single-use products adds up quickly. A refillable kit gives you a much lower cost per day.
• A person who is rough on devices: commuters, tradespeople, people who work outdoors or walk a dog every day, who want hardware designed to take knocks.
• A vaper who wants flexibility, such as the option to vape nicotine salts at moderate power one week and try a different coil resistance the next.
• Anyone who likes a mesh-coil flavour with reasonable battery capacity in a pocket-sized body.

You may want to look elsewhere if you are:

• A complete beginner who wants zero effort. If the thought of filling a pod and priming a coil sounds like a chore, a closed prefilled pod kit is simpler, although it costs more per day over time.
• A cloud-chaser who wants very large vapour production. A 2ml pod and a pocket-sized battery are not built for that, and a larger two-battery mod with a bigger tank, where legal, is a better match.
• A strict mouth-to-lung vaper who wants a very tight, cigarette-like draw. The airflow can be tightened, but a dedicated lower-power pod system is built specifically for that style and may feel more natural.
• Someone who dislikes the idea of a built-in battery. When the cell eventually wears out you cannot swap it yourself as you could with a removable-battery mod.
• A non-smoker, or anyone under 18. Vaping is for adult smokers who want an alternative, and this kit should not be bought as a lifestyle accessory by people who do not already use nicotine.

If you land in the first group, the Aegis M100 is a sensible, durable choice. If you land in the second, you will probably be happier with something designed for your preferred style, and it is better to know that before you spend the money.

How to set up and use your kit

Setting up a refillable pod kit for the first time takes about fifteen minutes, most of which is waiting for the coil to soak. Follow the steps below, and keep the manual to hand, since button sequences can vary slightly between hardware revisions.

• Step 1, charge it: plug the USB-C cable into the device and a suitable charger. A short charge before first use is wise even if the battery already shows some power.
• Step 2, check the coil: if the coil is not already installed in the pod, push it firmly into place until it seats fully. Wipe off any residue.
• Step 3, prime the coil: drip a few drops of e-liquid onto the cotton visible through the wicking holes. This is the step most beginners skip, and it is the one that most often saves a new coil.
• Step 4, fill the pod: open the fill port, which is usually a silicone bung on the top or side, and fill slowly with the bottle nozzle angled against the wall of the pod so you avoid forcing air into the central chimney. Stop just below the maximum line to leave room for air.
• Step 5, wait: leave the filled pod standing for five to ten minutes so the cotton can absorb liquid fully.
• Step 6, fit the pod: click the pod into the device and make sure it seats flush.
• Step 7, switch on: most Geekvape devices power on and off with five quick presses of the fire button, but follow your manual if it says otherwise.
• Step 8, set the power: begin at the lower end of the coil's recommended range, take two or three gentle puffs without inhaling deeply, then adjust.

In daily use, keep the device locked when it is in a pocket, top up the pod before it runs dry, and wipe the contacts between the pod and the body occasionally with a dry cotton bud. A small amount of condensation around the pod seat is normal and is cleaned with a tissue.

Changing a coil is simple. Remove the pod, empty the remaining liquid into the bin or back into a bottle if it is clean, pull the old coil free, and fit the new one. Rinse the pod with lukewarm water, let it dry for a few hours, then prime and refill as above. Never use a coil that has been wet or flooded without letting the pod dry first, as water in the electronics does no good to any device.

Troubleshooting common problems

Most problems with refillable kits come down to a handful of causes, and most can be fixed in a minute. Here is a quick guide to the ones we see most often.

• The device will not fire or shows a check-atomizer message: take the pod out and put it back, making sure it clicks fully into place. Wipe the contacts, check that the coil is pushed all the way into the pod, and make sure the battery is charged. If the message persists with a new coil, try another pod to find out whether the device or the pod is at fault.
• A burnt or dry taste: usually caused by a coil that was not primed, a pod run too low, or a wattage set above the coil's rated range. Lower the power, top up the liquid, and if the burnt taste remains replace the coil.
• Gurgling noise or liquid in the mouthpiece: excess liquid or a flooded coil. Blow gently through the mouthpiece with the pod removed, wipe the chimney, and fill slightly less next time. Tightening the airflow a little can also help.
• Leaking from the pod or airflow slots: check that the fill port is fully closed, that the coil is seated properly and that the pod is not overfilled. A cracked pod needs replacing. Hot cars and flights can make a pod leak because of pressure and temperature changes, so empty the pod when you know you will be in either.
• Weak vapour or flat flavour: the coil is probably worn, the liquid is too thick for the setting, or the wattage is too low. Try a modest increase in power or fit a fresh coil.
• Vapour too hot: reduce the wattage, open the airflow a little, and take shorter puffs.
• The device will not charge: try a different cable and a different charger, since cable failure is far more common than device failure. Clean any lint out of the USB-C port gently with a wooden cocktail stick. If it still will not charge, contact us.
• The display shows low battery but the device seems to be fully charged: leave it connected to the charger for a longer period, then check again. A battery near the end of its life may report inconsistent readings.

If you have worked through these steps and the device still misbehaves, stop using it and get in touch with your order number. Do not open the casing or try to repair the battery yourself.

When the device finally reaches the end of its life, do not put it in your household bin or kerbside recycling. It contains a lithium-ion battery, which can start fires in waste vehicles and recycling plants. Take it to a vape drop-off point, a household waste recycling centre that accepts small electricals, or return it to a shop that offers take-back. Recycling the device and used coils responsibly is part of owning a reusable kit.

Value for money, alternatives and UK notes

Value is not only the sticker price on the kit. The real comparison is cost over a few months. A single-use disposable could be thrown away after a few days, and since they are no longer legal to supply in the UK, that comparison matters mostly for anyone remembering what they used to spend. A refillable kit costs more on day one but much less per day after that. Your running costs are e-liquid, which is typically a few pounds per 10ml bottle, plus a new coil every one to three weeks. For a regular user that comes out far below the cost of a pack of cigarettes and below what repeated single-use products used to cost. Add the fact that a well-built device from a major brand should last well over a year, and a kit in this price band tends to pay for itself within the first couple of months.

Here is how it compares with other options, as fairly as we can put it. Check current specifications on each product page, since models are revised regularly.

• Vaporesso GEN range (such as the GEN 80 S): a similar class of pod mod with a strong reputation for flavour and a wide choice of coils. It tends to pitch itself on style and a larger display. The Aegis family differs mainly in its emphasis on durability.
• Voopoo Drag range (such as the Drag X or the Drag M100S): comparable power and a wide ecosystem of PnP coils, which gives you plenty of choice in resistance. It is a strong competitor on coil variety. Our reading is that Geekvape pulls ahead where toughness matters more to you than choice of coil.
• SMOK Nord range: easy-to-find coils in many shops and a long track record. Some models are a little more basic in terms of protection and ruggedness, but they are straightforward to use.
• Smaller, lower-power pod systems such as the Uwell Caliburn or Oxva Xlim families: better if you want a tight, cigarette-like draw and a slimmer body, and generally cheaper. They cannot match a 100W-class kit for vapour production or flexibility.

None of these is automatically better than another. The right pick depends on whether you value durability, coil variety, size or the tightness of the draw. For people who want a hard-wearing everyday device with decent power, the Aegis M100 is an easy kit to justify.

A few UK points to finish. You must be 18 or over to buy, and we may ask for age verification. Refillable tanks are limited to 2ml, e-liquid bottles to 10ml, and nicotine strength to 20mg per ml. Buy e-liquid from a reputable UK retailer rather than unlabelled sources, and keep all vaping products and liquids out of reach of children and pets. Finally, once the device wears out, recycle it through a proper drop-off point rather than binning it.
