Geekvape Soul 2: what this refillable pod is worth
The Geekvape Soul 2 landed in 2025 as the second generation of a refillable pod the brand had launched the year before. On paper the promise is simple: keep the logic of the first Soul, grow the battery, widen the power range and tidy up the screen. This article goes through the spec sheet line by line, clears up exactly what the product name covers, and sets out what UK rules change about the capacity figure you will see quoted online.
Geekvape Soul 2: which model are we actually talking about
Geekvape sells several objects under the Soul name, and the confusion is common in shops and online alike. There is the first generation Soul from 2024, and the Soul 2 that succeeds it. On top of that sit the cartridges, sold as Soul and Soul Boost, which do not map neatly onto one another across the two generations.
What is covered here is the Soul 2 pod kit, meaning the battery and cartridge sold together in a box. It is not a box mod, not a device running a removable cell, and not a closed system using pre-filled capsules. It is a refillable cartridge pod that the user fills with the e-liquid of their choice.
The distinction matters because the numbers change from one model to the next. The first generation Soul carries a 1500 mAh battery and a 30 W ceiling, where the Soul 2 moves to 2100 mAh and 35 W. Mixing the two spec sheets is the fastest way to end up quoting figures that are simply wrong.
What the Geekvape Soul 2 spec sheet states
Battery life is the headline. The Geekvape Soul 2 carries a 2100 mAh rechargeable battery, against 1500 mAh on the previous generation. That figure is consistent across the review published by Vaping Post in May 2025, the manufacturer listing and the Soul versus Soul 2 comparison put out by specialist retailers.
The stated power range runs from 5 to 35 W, again according to those same sources. This is not a figure you sit at permanently. The chipset reads the installed coil and limits the setting to the range the manufacturer validated for that cartridge, so the upper bound only unlocks with the cartridge designed for it.
Charging is over USB-C, from the underside of the device. The screen is small, sits under a transparent finish and stays invisible until it is woken. That is a deliberate design decision, and it is also the main criticism raised in the specialist press: brightness is judged insufficient in direct sunlight.
Weight sits at around 90 g according to published measurements, which puts the object in the category of pods you carry without thinking about, while still being more present in the hand than the truly tiny formats. Firing is either automatic on the draw or on the main button, whichever the user prefers.
Cartridges and coils, the real centre of gravity
The kit ships with two Soul Boost cartridges. The first carries a 1.0 ohm coil, which the manufacturer states for use between 5 and 15 W with a tight draw. The second carries a 0.6 ohm coil, stated between 15 and 30 W, for a more airy inhale.
A third reference exists, a 0.4 ohm cartridge stated between 30 and 35 W, sold separately. That is the one that reaches the top of the range. These three values and their ranges are the ones published by the distributor and repeated in the Vaping Post review.
Those ranges are not loose guidance you can wave away. They correspond to what the manufacturer validated for each coil, and the device holds itself to them without being asked. On a product aimed at a broad audience, that is a sensible piece of design.
Airflow is set by a rotating ring at the top of the cartridge, reachable once the magnetic cap is off. Filling is from the side, under a silicone bung. Nothing exotic, but a clean execution, with windows that let you see the liquid level.
Capacity: what UK rules change
This is the point that needs stating precisely, because a great many listings in circulation quote a number that does not match what is legally sold in Britain. UK rules cap a refillable tank or cartridge intended for nicotine e-liquid at 2 ml, alongside a 20 mg/ml ceiling on nicotine strength and a 10 ml limit on refill bottles.
The larger capacities you will see in international descriptions of the Geekvape Soul 2 refer to versions destined for other markets. In a UK specialist shop, the cartridge you buy respects the 2 ml cap. Taking the international figure at face value means overestimating how long a fill will last you.
In practice that means refilling more often than some listings imply. It is a constraint shared by every refillable pod legally sold in the UK, not a weakness particular to this model, and it is worth knowing before you compare two spec sheets side by side.
An integrated battery and what that implies day to day
The Soul 2 battery is built in, so it is not removable. There is no cell to buy, screw in or carry separately, and no choice of cell to make. That architecture simplifies ownership and removes a whole class of handling mistakes tied to loose cells.
On devices that do run a removable cell, the sound practice is to read the datasheet published by the cell manufacturer, not the description written by a reseller or a forum post. Those datasheets state the true capacity, the maximum continuous discharge current and the nominal voltage. Cross-referencing those published values against what a given setup actually draws is the only way to judge whether a cell suits it.
A few habits apply to any vaping device, integrated battery or not. The plastic wrap around a cell must stay intact, with no tear or nick. Transport happens in a rigid case made for the purpose, never loose in a pocket alongside keys or coins. And charging is done with a charger suited to the device, following the manufacturer's instructions.
Who this pod is for
The Soul 2 is positioned as an all-rounder. The two supplied cartridges cover two fairly different draw styles, which lets you try both without buying more hardware straight away. For an adult vaper still undecided between a tight draw and a looser one, that is a concrete advantage.
Anyone chasing absolute discretion will find slimmer formats elsewhere on the market. Anyone wanting comfortable battery life across a long day without moving up to a box is squarely in the target this product was designed for.
To place this kind of hardware in context, our report on e-cigarettes in Paris shows how far refillable pods have taken over since disposables were pulled from sale. The same movement is visible in our piece on e-cigarettes in Lyon, with buyers paying closer attention to spec sheets than they used to.
For the opposite product philosophy, our look at the blu pod range covers a closed system where the user fills nothing at all. The two approaches are not aimed at the same use.
FAQ
What is the difference between the Soul and the Soul 2? The second generation moves from 1500 to 2100 mAh of battery and from 30 to 35 W of stated maximum power. It is also slightly heavier and adopts a borderless integrated screen. The operating principle is unchanged.
Which coils come with the kit? The box holds two Soul Boost cartridges, one at 1.0 ohm stated for 5 to 15 W and one at 0.6 ohm stated for 15 to 30 W. A 0.4 ohm cartridge stated for 30 to 35 W is sold separately.
Can you really run this pod at 35 W? Only with the cartridge designed for that range. The device reads the installed coil and will not allow a setting beyond what the manufacturer validated for it.
What is the cartridge capacity in the UK? It is capped at 2 ml, like every refillable tank intended for nicotine e-liquid sold in Britain. The larger capacities shown on some listings apply to other markets.
Is the battery replaceable? No, it is integrated into the device and charges over USB-C. There is no cell to choose or to handle separately.
Geekvape Soul 2: what to take away
The Geekvape Soul 2 is a coherent update rather than a break with what came before. The 2100 mAh battery and the 5 to 35 W range answer the main criticism aimed at the first generation without complicating the device. The Soul Boost cartridge system, with three coil values and power ranges policed by the chipset, covers a genuinely wide spread of draw styles.
Two points are worth keeping in mind before deciding. The screen, neatly integrated as it is, lacks brightness outdoors, a criticism that comes up unanimously in published reviews. And the real capacity in the UK stays capped at 2 ml, whatever figure an international listing shows.
For an adult vaper who wants a versatile refillable pod that is well built and legible in its settings, the Geekvape Soul 2 holds its place without overreaching. For anyone whose priority is maximum discretion and the lowest possible weight, other formats on the market will answer better.
