Understanding Nicotine Salt Strengths in the Crystal 600 Pro Range

What the nicotine strength options mean and how to choose the right one.

Quick answer: The Crystal 600 Pro was available in 10mg/ml and 20mg/ml nicotine salt. The 20mg version is appropriate for most smokers switching from 10 or more cigarettes per day. The 10mg version suits lighter smokers or users who have already reduced their nicotine intake. Both deliver nicotine via nicotine salt for a smooth, fast-absorbing hit.

Choosing the correct nicotine strength is the single most important factor in switching successfully from cigarettes to vaping. Too low and cravings persist; too high and the experience can be uncomfortably intense.

Crystal 600 Pro Nicotine Options Explained

Strength	Total nicotine in device	Cigarette equivalent	Who it suits
20mg/ml (2%)	2ml x 20mg = 40mg total	~20 cigarettes (1 pack) across full device	10+ cigarettes per day; standard switcher strength
10mg/ml (1%)	2ml x 10mg = 20mg total	~10 cigarettes (half a pack) across full device	Fewer than 10 cigarettes per day; users stepping down

What Nicotine Salt Means

Nicotine salt (nic salt) is nicotine combined with a mild organic acid, typically benzoic acid. This combination lowers the pH of the liquid, which produces a smoother throat feel at high concentrations and allows the nicotine to absorb through lung and mouth tissue more quickly than freebase nicotine. The result is a faster, more satisfying nicotine hit that more closely replicates the speed of nicotine delivery from a cigarette.

This is why a 20mg nic salt Crystal 600 Pro feels significantly less harsh than a 20mg freebase vaping device would. The throat smoothness is a deliberate formulation choice, not a sign of weakness.

Frequently Asked Questions

Not necessarily. The "cigarette per day" figure is a guide, not a precise threshold. If you find 20mg causes nausea, dizziness or headaches, step down to 10mg. If 10mg does not satisfy cravings, step up to 20mg. Nicotine needs vary between individuals based on metabolism, smoking history and depth of inhalation. Start with 20mg if in doubt and adjust based on your experience in the first few days.

Yes. Some users alternate between a 20mg device in the morning when cravings are stronger and a 10mg device in the evening. Since the Crystal 600 Pro is a sealed single-use device, there is no mixing of liquids involved; you simply use whichever device matches your current need. This is a valid approach if you want to manage total daily nicotine intake more precisely.

20mg/ml and 2% are the same concentration expressed differently. 20 milligrams of nicotine per millilitre equals 20 grams per litre, which equals 2 grams per 100ml, which is 2%. UK TRPR regulations cap the maximum at 20mg/ml (2%). Both expressions appear on UK vaping products. If you see either notation, the other can be calculated directly.

No. Nicotine strength is independent of vapour production. A 20mg device and a 10mg device with otherwise identical components produce the same amount of vapour. The difference is only in nicotine content per millilitre. Vapour production is determined by the coil, battery power and airflow design.
