Like most things in the vape world there are a few exceptions on what I’m about to advise, but in most cases here’s what we find the best… so… if you have an MTL device with a high resistance coil (above 0.7ohms) and low wattage supplied from the battery (up to 60 watts) then we would usually recommend a 50VG/50PG e-liquid, or possibly a 60VG 40PG. If you are using a DL device then you will likely have high wattage (70 watts upwards), low resistance coils (below 0.7ohms ), this usually works better with a 70/30 or 80/20 e-liquid.
The e-liquids usually come in various sized bottles. 10ml, 50ml, 100m,l and 200ml are the most popular, however there are 25ml, 40ml, 60ml and other random sizes up to 1ltr. 10ml are the official size and these usually contain nicotine and are fully TPD compliant, in brief this means that the nicotine contents of a 10ml bottle must not exceed 2.0% or 20mg/ml, among many other EU guidelines and restrictions. If you are purchasing a bottle of e-liquid above a 10ml capacity then it is not TPD( Tobacco Products Directive) compliant and can therefore not contain nicotine, the consumer would usually purchase small bottles of nicotine in a 10ml bottle, which they would then add (there selves) to the bigger bottles of e-liquid.
This does not necessarily need to be measured out as such, as you would just usually pour a full 10ml bottle of nicotine ‘nic shot’ into a 50ml bottle of e-liquid, which would give you an estimated total of 3mg nicotine strength within that 50ml bottle of e-liquid (which would now be £60ml of liquid).
As a rough guide of nicotine to e-liquid ratio, would go like this;
|Amount of 0mg E-Liquid||Amount of 10ml 18mg Nic Shot Added||Overall Liquid (ml) and Nicotine (mg)|
|50ml||1||60ml of 3mg e-liquid|
|100ml||2||120ml of 3mg e-liquid|
|Amount of 0mg E-liquid||Amount of 10ml 15mg Nic shot Added||Overall Liquid (ml) and Nicotine (mg)|
|40ml||1||60ml of 3mg e-liquid|
|80ml||2||120ml of 3mg e-liquid|
Simply double the amount of nic shots added to your short fill in order to double the overall strength.
Please be responsible with your nic shots with short fills, if you prefer it with 18mg of nicotine we would recommend sticking to TPD, don’t start throwing 6 and 10 battles of nic shots into a bigger container with your 50ml of juice, nicotine is a toxic chemical, so please be cautious of that.
Most short fills don’t seem to cater for those who would rather higher nicotine levels, with the common strength of short fills generally being 0mg, 3mg and 6mg. The most common nicotine shot is normally 18mg of nicotine in a 10ml bottle however there are 15mg nic shots available too. Some people do prefer to add 2x 15mg nic shots instead of x2 18mg nic shots, especially to an 80ml e-liquid, but this is all trial and error and personal preference. Most websites will offer to add a nic shot to your basket when you’re purchasing short fills, however the rules are constantly changing and you may not have it so easy in the near future, you may have to go to another section of the web site in order to purchase your nic shots.
It is also important to remember that adding more nicotine shots to your 0mg of e-liquid will dilute the flavours, which no one wants!
