Most reviews of the IVG Pro system spend their word count on flavours and puff counts, and understandably so — a wall of 39 flavours and a ten-thousand-puff rating make good headlines. But the single decision that most shapes whether this kit works for you is quieter and less glamorous: which nicotine strength you put in it. Get it right and a few puffs satisfy you for an hour; get it wrong and you will either chain-vape all day or find the experience harsh and off-putting. This guide is a full deep-dive into the three strengths available across the range — 20mg, 10mg and 0mg — covering what nicotine salt actually is, how each strength feels in practice, who each one suits, and how to use the three-tier system as a genuine step-down ladder if reducing your intake is the goal.
The System in Brief
Quick context for new readers. The IVG Pro is a rechargeable pod kit — launched as the Pro 10K, now sold as the Pro 12, with a companion Pro 2 device, all taking the same refills. Each refill pack pairs a 2ml mesh-coil pod with a 10ml container that automatically tops it up as you vape: 12ml of nic salt e-liquid in total, rated at approximately ten thousand puffs. There is nothing to fill and no coil to change; when the liquid is gone you swap the whole unit. Everything below applies to the standard ivg pro 10k refills that fit all three devices.
Nicotine Salt: Why the Formulation Matters
Before comparing numbers, it helps to understand what kind of nicotine you are choosing between, because the milligram figure alone does not tell the story. All IVG Pro pods use nicotine salt rather than the older freebase nicotine found in traditional e-liquids. Freebase nicotine gets progressively harsher on the throat as strength rises, which is why old-school liquids rarely went above 12mg comfortably. Nicotine salt is a modified form — closer to the state nicotine takes in tobacco leaf — that is dramatically smoother to inhale and absorbs into the bloodstream faster.
The practical consequences are two-fold. First, a 20mg nic salt pod feels far gentler than the number suggests; smokers who tried harsh high-strength freebase liquid years ago and gave up should not assume this will feel the same, because it does not. Second, the fast absorption means satisfaction arrives in a cigarette-like timescale — a couple of minutes rather than the ten-plus that freebase needed. That speed is exactly why nic salt devices became the default tool for switching smokers: the craving-to-relief loop finally matches what a cigarette delivered.
20mg (2%): The Standard
Twenty milligrams per millilitre — two percent — is the maximum nicotine concentration legal in the UK, and it is the strength the entire flavour range ships in. This is the setting for current smokers making the switch, for anyone who previously used disposables (which were almost universally 20mg), and for heavier vapers generally. In use, the 20mg pods deliver a noticeable but smooth throat hit with a satisfaction curve that closely mimics smoking: a short session of eight to twelve gentle puffs does the job of a cigarette, and then you naturally put the device down.
The common worry — that 20mg is ‘too strong’ — is usually a misreading of how strength works in practice. Nicotine intake is self-regulating: with an adequately strong liquid you vape briefly and stop, while with an under-strength one you compensate by vaping far more, often absorbing a similar total while burning through liquid and never quite feeling settled. For a ten-a-day-or-more smoker, 20mg is not the aggressive option; it is the accurate one. Signs it genuinely is too strong for you — light-headedness after short sessions, a throat hit you find sharp even with gentle draws — are your cue to try 10mg, and they are more common among very light or social smokers.
10mg (1%): The Middle Step
The 10mg tier covers roughly fifteen of the range’s most popular flavours — the big ice fruits, the cherries, the core menthols — and it exists for two audiences. The first is light smokers: if your habit was a handful of cigarettes a day, half-strength salt often satisfies fully without the slight buzz 20mg can give lighter users. The second, larger audience is steppers-down: established vapers who have decided to reduce their nicotine intake and want a manageable intermediate stage rather than a cliff-edge.
In the mouth, 10mg pods are noticeably softer — the throat hit recedes to a whisper and the flavour arguably steps forward slightly without the nicotine pepperiness underneath. The trade-off is honest: satisfaction per puff halves, so expect to take somewhat more puffs per session while your body adjusts, and expect a pack to empty a little faster during the transition. That settles down within a week or two for most people as the new level becomes normal.
0mg: Flavour Without the Nicotine
The nicotine-free tier is the smallest — around thirteen flavours, weighted toward the best-selling fruit-ice profiles — and the most misunderstood. Who vapes zero nicotine? Primarily people at the end of a step-down journey: the physical dependence is gone, but the hand-to-mouth ritual, the flavour and the exhale remain genuinely enjoyable and, for many ex-smokers, protective — a harmless-feeling stand-in during the moments that used to trigger a cigarette. The 0mg pods use the identical dual-chamber system and mesh coil, so nothing about the experience changes except the absence of throat hit, which makes the vapour feel notably softer and sweeter. If you are here, congratulations: you have done the hard part, and this tier exists so you never have to renegotiate your flavours on the way out.

Matching Strength to Your Smoking History
For switchers, the honest mapping looks like this. Fifteen or more cigarettes a day, or any roll-up habit: start at 20mg without hesitation — under-dosing is the number one reason switch attempts fail. Ten to fifteen a day: 20mg remains the safer starting bet, stepping to 10mg later if it ever feels like too much. Under ten a day, or social smoking: 10mg is a reasonable starting point, with 20mg in reserve if cravings persist. Never smoked or vaped: none of these — nicotine products are for existing users, full stop. The universal rule underneath all of it: start where your habit actually is, not where you wish it were. Aspiration is for the step-down phase, not day one.
How to Step Down Properly
The three-tier structure makes the IVG Pro one of the better reduction platforms in the prefilled category, because you can lower your nicotine without changing device, draw, or — if you pick your flavours from the pods stocked at all strengths — even taste. But technique matters. Move to a lower tier only once you are stable at your current one: comfortable, not white-knuckling, with pods lasting as long as they used to. When you drop, expect a week or two of slightly increased vaping as your intake finds its new level; that is normal compensation, not failure. Resist the temptation to skip from 20mg straight to 0mg — the double-halving route through 10mg has a far better completion rate, because each step feels like an adjustment rather than a withdrawal.
Two further tips from the trenches. Time your drops sensibly — a calm fortnight, not the week of a house move — because stress is the classic trigger for reaching back up. And consider a mixed rotation as a soft launch: running a 10mg pod at home and a 20mg out and about for a while lets the reduction happen gradually across the day, and the click-in-click-out pod design makes that trivially easy in a way bottle kits never were.
Mistakes That Undermine the Whole Thing
Four errors account for most strength-related complaints. Starting too low out of caution, then blaming the kit when cravings win — covered above, but worth repeating because it is ubiquitous. Judging a strength by its first day, before your draw technique settles; give any new tier at least a full pod before ruling. Compensating for a drop by pulling harder — long aggressive draws flood the mesh coil and waste liquid without meaningfully raising absorbed nicotine; take more gentle sessions instead. And chasing throat hit for its own sake: if you miss the scratch after stepping down, a menthol or ice flavour restores much of the sensation with zero added nicotine, which is one of the range’s more useful open secrets.
How Strength Interacts with Flavour
One under-discussed nuance: nicotine level subtly changes how flavours taste, and knowing this saves confusion when comparing tiers. Nicotine itself carries a faint peppery bite, so 20mg pods layer a touch of warmth and edge under every profile — welcome in menthols and darker fruits, where it adds body, and barely noticeable in bold ice blends. Drop to 10mg and flavours read slightly sweeter and cleaner as that undertone recedes; sensitive palates often say the fruit profiles taste truer at this tier. At 0mg the effect is fullest — vapour turns notably soft and dessert-like, which flatters candied profiles like blue raspberry but can leave stark menthols feeling like they are missing a gear, since much of a menthol’s perceived punch was the nicotine all along. None of this is a reason to pick a strength on taste alone — satisfaction comes first — but it explains why the same flavour reviewed at different strengths reads like two different pods, and why ice-heavy profiles are the smart anchor choice for anyone planning to travel down all three tiers.
It also means your draw technique deserves a brief recalibration at each tier. At 20mg, short gentle sessions extract everything you need; at 10mg, slightly longer or more frequent sessions are normal and nothing to fight; at 0mg, vape however feels pleasant, because the only currency left is flavour. Vapers who carry their 20mg habits unchanged into lower tiers are the ones who report a step-down ‘not working’ — adjust the rhythm along with the number and each tier settles within days.
Strength FAQs
Do all strengths cost the same? Yes — pricing is per pack regardless of nicotine content, so stepping down carries no financial penalty. Does 0mg last longer? Puff count is identical; the liquid volume and coil are unchanged. Can I tell strengths apart by packaging? Yes, the strength is printed clearly on every pack — 20mg (2%), 10mg (1%) or 0mg — alongside the standard UK nicotine warning on the nicotine-containing tiers. Is anything above 20mg available? No, and treat any listing claiming otherwise as counterfeit — 20mg is the UK legal ceiling, and legitimate IVG Pro 10k refill pods never exceed it. Will mixing strengths in rotation confuse my body? No; total daily intake is what matters, and blended rotations are a recognised, sensible reduction tactic.
Where to Buy Across All Three Tiers
Because the 10mg and 0mg tiers are smaller runs than the flagship 20mg wall, physical shops often stock only the full-strength versions — frustrating if you are mid-step-down and your flavour vanishes from the shelf. Online is the reliable route: Pink Vape carries IVG Pro 10000 puffs across the available strengths with multi-buy pricing and fast UK delivery, which makes maintaining a mixed-strength rotation straightforward. As always, buy from established UK retailers and check for compliant packaging; strength labelling is precisely where grey-market stock cuts corners.
The Bottom Line
Flavour gets the attention, but strength does the work. The IVG Pro’s three-tier range is quietly its most important feature: 20mg to make switching from cigarettes genuinely stick, 10mg to make reduction achievable rather than theoretical, and 0mg so the finish line does not require giving up a ritual you have come to enjoy. Choose your starting strength based on honesty about your habit, step down based on stability rather than ambition, and the system will meet you at every stage of the journey. Adults 18 and over only — and if nicotine is not already part of your life, no tier of this range is for you.
