Elux Legend's 10mg/ml and 20mg/ml nic salts are the same e-liquid in every way except one, how much nicotine is in each millilitre, and that single difference changes more about how a vape feels day to day than it might seem to on paper.
What Actually Differs Between The Two
Nothing changes except the nicotine concentration. Both strengths use the same nic salt formula, nicotine combined with an organic acid to keep the throat hit smooth even at higher concentrations, covered in more depth in the nic salt versus freebase piece elsewhere on this site. Both use the same 50/50 VG/PG ratio and the same flavour.
The only figure that changes between a 10mg/ml and a 20mg/ml bottle is the amount of nicotine per millilitre, 20mg/ml containing exactly double the nicotine of 10mg/ml in the same volume of liquid.
| 10mg/ml | 20mg/ml | |
|---|---|---|
| Nicotine per ml | 10mg | 20mg (UK legal maximum) |
| VG/PG ratio | 50/50 | 50/50 |
| Flavour | Identical across both | Identical across both |
| Puff pattern | More frequent, milder | Fewer, stronger |
| Best suited to | Smoother, more frequent draw | Firmer throat hit, less frequent draw |
Does Strength Change How It Tastes?
Mostly no. Flavour comes from the flavouring concentrate and the VG/PG ratio, neither of which changes between strengths, and most sources checked for this piece confirm flavour is unaffected by nicotine concentration. One source did note a slight flavour-muting effect at 20mg/ml compared to 10mg/ml, though this isn't consistently reported elsewhere, worth knowing as a minor, unconfirmed observation rather than something to expect as a rule.
The Real Difference Is How Much Nicotine Reaches You Per Puff
This is the part that actually shapes day-to-day use. At 20mg/ml, more nicotine reaches you in a single draw, which tends to mean shorter, less frequent puffs feel satisfying. At 10mg/ml, nicotine delivery per puff is lower, so reaching a similar level of satisfaction often means vaping somewhat more frequently across a session.
Neither pattern is better than the other, it's a genuine trade-off between fewer, stronger puffs and more frequent, milder ones, and which suits you comes down to how you actually prefer to vape rather than anything about the liquid itself being better or worse at one strength.
Device Wattage Matters More At 20mg/ml
Both strengths are built for the same low-wattage MTL pod kits Elux Legend is designed around, generally somewhere in the 10 to 25W range, but this matters more at 20mg/ml specifically. Vaping 20mg/ml through a higher-wattage device than it's designed for pushes considerably more nicotine into each puff than intended, which some people find uncomfortable rather than satisfying.
Keeping 20mg/ml in the low-wattage MTL devices it's built for avoids this. This is the same wattage range covered in more detail in the ingredients and VG/PG ratio piece elsewhere on this site, which also explains why the ratio itself, not just the strength, is built around this specific format.
It's worth knowing that nicotine in excess of what feels comfortable can cause lightheadedness or nausea, a standard pharmacological fact about nicotine generally, not something specific to any one strength or brand.
Why Nothing Else Needs To Change When You Switch Strength
Because the underlying formula, ratio and flavour stay identical between 10mg/ml and 20mg/ml, moving between the two doesn't mean relearning anything about your device or your favourite flavour. The same pod, the same coil, the same low-wattage setup that suits one strength suits the other, only the nicotine concentration in the bottle changes.
This is different to switching between entirely different products, where flavour, ratio or even the device itself might need reconsidering, here it's genuinely a single variable, which makes trying the other strength a low-effort way to see which suits you better rather than a decision that needs much research beforehand.
Thinking About Frequency, Not History
The clearest way to choose between the two isn't looking backward at anything, it's thinking about how you currently vape or expect to. If you'd rather take fewer, more concentrated puffs across a day and don't mind a firmer throat hit, 20mg/ml, the UK legal maximum under the Tobacco Products Directive (TPD), implemented through the Tobacco and Related Products Regulations 2016, delivers that (gov.uk/guidance/e-cigarettes-regulations-for-consumer-products).
If you'd rather have a milder, smoother draw and don't mind vaping a little more often to get there, 10mg/ml does that instead. Some people also simply keep both on hand and choose depending on the moment, there's no rule that says a bottle of each isn't a perfectly reasonable way to cover both preferences.
If You're Still Not Sure, Trying Both Costs Less Than You'd Think
Because a 10mg/ml and a 20mg/ml bottle of the same Elux Legend flavour differ in nothing but nicotine concentration, there's no real downside to picking up both and comparing them directly over a few days rather than trying to reason it out in advance.
Vape the 20mg/ml for a day or two, note whether the puff count and throat hit feel right, then do the same with the 10mg/ml. Most people know fairly quickly which one feels more natural once they've actually tried both back to back, and since the flavour and device setup stay identical either way, it's a genuinely low-effort comparison rather than a big commitment either direction.
It's worth being direct about this: neither strength is objectively better, they're built for different preferences around how nicotine is delivered, not different tiers of quality or a beginner-versus-advanced split. Someone who's vaped for years might genuinely prefer 10mg/ml for the smoother, more frequent draw, and someone new to Elux Legend might find 20mg/ml suits them from the start. The right one is whichever matches how you actually like to vape, not a fixed rule either way.
FAQ
What's the actual difference between Elux Legend 10mg/ml and 20mg/ml?
Only the nicotine concentration. Everything else, flavour, ratio, formula, is identical between the two strengths.
Does 20mg/ml taste stronger or different to 10mg/ml?
Mostly not. Flavour comes from the flavouring and ratio, not nicotine strength, though one source noted a slight muting effect at 20mg/ml that isn't consistently reported elsewhere.
Will I vape more often on 10mg/ml than 20mg/ml?
Often, yes, since less nicotine reaches you per puff at 10mg/ml, some people find they draw a little more frequently to reach the same satisfaction than they would on 20mg/ml.
Can I use 20mg/ml in any device?
It's built for low-wattage MTL pod kits specifically. Using it in a higher-wattage device pushes more nicotine into each puff than intended, which can feel uncomfortable rather than satisfying.
Is 20mg/ml the strongest nic salt available in the UK?
Yes. 20mg/ml is the legal maximum for nicotine containing e-liquid under UK TPD regulation, so nothing sold legally in the UK goes higher than Elux Legend's 20mg/ml option.
Do I need a different device to switch between 10mg/ml and 20mg/ml?
No. Both strengths use the same formula, ratio and flavour, so the same pod kit and coil suit either strength without any changes.
Can I mix 10mg/ml and 20mg/ml bottles, or keep both?
There's no reason not to. Some people keep both on hand and pick whichever suits how they're feeling or the time of day, since the two are otherwise identical.
What's the easiest way to decide between the two?
Try both directly rather than reasoning it out in advance. Since flavour, ratio and device setup stay identical between strengths, vaping each for a day or two is a low-effort way to find out which suits you without any real downside either way.
